The horrific instruction manual I got with my Raiden Tech Zero Fighter-25 resulted in a mistake and damage to the covering. I cut the cover where the instructions sorta kinda pointed to and realized with a horrid sinking feeling that I'd just opened up a hole in the wrong place.

A great big nicely trimmed rectangular one.

I about had a fit.

Calling their toll free number resulted in no live help whatsoever. All I got was a generic computer that kept telling me it would try to connect me, all to the strains of "Take Five."

At least it was the Brubeck original. Over and over and over. No live help no matter what I did with my phone. Five minutes, ten...no answer.

Well, directory assistance wasn't able to find the place and the number I did find for the company online is busy. Constantly.

However, I finally got lucky and got a live tech who was quite helpful. While he didn't have the olive drab covering on hand, he did have some of the gray covering used on the underbelly. Since there's always a chance that the underbelly might get dinged by a rock or something, I took him up on his offer to send me some of that color. As far as the wait on the phone is concerned, I just needed to wait longer than I was able to spare. Eventually, I'd have gotten through.

Thank goodness I kept the elevators from the crashed Zero. I have no idea why. I should point out that I received the first plane with the tailfeathers already installed and I...Continue Reading

The new Zero is coming along nicely despite every effort of the instruction manual to make it do otherwise. When the review comes out, you'll see how much I love the plane (so far) and hate the manual.

I go a nice, warm welcome at the AMA Gold Certified local field yesterday. Nice folks, all. Somehow, that club had gotten a reputation for elitism and snobbery toward those with electrics. Booshwah. Nicest folks you ever want to meet who do a lot for the community in return. In fact, a grandfather/grandson team were having a ball with a GWS Slow Stick soon after the club president landed his 100mph delta wing.

The combat plane made the ride with me. Unfortunately, it bit me. The idle was too fast; it was the first time I'd flown it since tweaking the throttle cable. I reached around the back to pinch the fuel line and ka-WHANNG! Took a nice chunk out of my right thumb. Despite "leaking" all over the sidewalk, it was more of a glancing blow than a deep, direct one. I got lucky. If I'd have been there alone, I would have been a long way from first aid.

Unfortunately, the plane didn't like ROG from the pavement, so it was time for a hand launch. REAL fun with a sliced-up thumb and bloodsoaked dressing. It flew fine, but the engine loaded up soon afterwards. Didn't quite make the field and the new landing gear got tweaked. No biggie; relaunched without the gear...started loading up again...and I brought it in for a nice, greased belly landing before it stalled. Looks like I may have an air bleed problem along with that thumb bleed problem (which, by the way, looks a lot better this morning than it did yesterday). Lots of fuel and oil in the muffler.

I needed to change the dressing on the thumb and I figured I'd had enough. Still, a great day despite having left a lot of DNA on their patio.

...so why do certain ones of great importance always seem to be on backorder?

Wouldn't you know it.

All the parts for my HPI Savage 25 came in today as did my Hitec GS-81 servo gears and FlyZone Cessna 182 Skylane main gear. It turns out that I had landing gear for my combat plane right under my nose; I cannibalized the Skylane park flyer for its aluminum main gear. Perfect fit. Two DU-BRO Ultra Lite wheels which I had on hand and one DU-BRO micro tail skid later, that combat plane now does perfect ROG's, at least from a dirt runway. It wanted to pirouette on the club's asphalt runway, so I may experiment with installing a steerable tailwheel. Three channel plane, four channel radio! Anyway, it was worth the $14 it cost me to replace the thing (complete with wheels, hardware and wheel fairings), especially since I was planning on doing so anyway after it got tweaked in a crash some months ago and never did fit right since. That's the good news.

The servo gears for the GWS Naro Pico servo I need for the throttle of my Raiden Tech Zero Fighter-25 didn't. They're on backorder, for cryin' out loud. Either there are a lot of people stripping gears or those servos have lousy gears that need replacing often. I haven't used them long enough to give an opinion either way.

I could have lived without the parts for the Savage, but doggone it, I need those servo gears, especially since I'll be writing a review.

I guess it won't be a total loss. I can now rebuild the Hitec aileron servos which means I can assemble the wing and photograph its progress at the same time.

The hobby shop promised to look into exactly how long the backorder will last; I'll know by Friday. If it'll be too long, I'll simply get a new servo.

Which I'll have to order.

The hobby shop is out of stock...

Talk about service!

The new Zero Fighter-25 from Raidentech.com was on my doorstep less than 24 hours after I ordered it. It was here before the new servo gears I ordered from the hobby shop...and I'm still waiting for those!

I've installed the engine, but that's as far as I can go without the servos, so the project begins anew next week.

I got in touch with Angela and I hope to do a review of the build and the (hopefully crash-free) flying in the magazine. Snapped a few pix of the fuse last night along with detail shots of the packaging and other components. The AMA membership is renewed and I'll be testing the plane at one of the premier club fields in the country. The Coachella Valley Radio Control Club hosted the turbine meet last year that was covered by the AMA in Model Aviation last November. The president has been egging me to join up for months.

Heck, how can I say no?

No frequency hits, no crazed bees like the one that insisted on divebombing my head one day, no dust, no noseovers due to irregular ground.

I'll have shade, work tables, a place to sit and a HUGE runway to ROG from.

Not a bad tradeoff...

It's amazing what a little bit of time will do to your point of view and your attitude.

I figured that it wasn't worth getting upset over the loss of an ARF that I could replace for $80. Sure, I was upset at losing a plane which I'd worked hard to get airborne again, but it's really not too much of an issue when one can replace the thing for relatively little money. Heck, rekitting a park flyer like a ParkZone J-3 or Flyzone Cessna from the ground up would cost about $80. A beautifully built balsa and ply warbird for that same price sounds pretty good to me.

What surprises me is the lack of choices in the .25 size range. Plenty of electrics in the "general vicinity," not many nitros.

So, thought I, why not just get another one of the same plane? It appears to be the least expensive ARF of its type on the market and it comes chock full of a lot of extras to boot, like a steerable tailwheel. The smaller, more expensive Great Planes Spitfire I'd been considering does not.

Plus, it's BIG. All the .25 planes I found had a wingspan of around 39". The new Zero will, like Project Zero before it, measure in at 49".

I'm off to the Raiden Tech or Nitro Planes website later tonight to place the order. Should be here in a couple of work days which means I can start the initial assembly on Friday if I'm lucky.

Boy, am I stoked!

It seems Great Planes makes a neat little Spitfire that'll accept my .25 and, in fact, they recommend the very engine I happen to have on hand waiting to be fully broken in. It has a 39" wingspan, a full 10" shorter than the recently deceased Zero and the same as my E-flite P-47.

Hmm...

This thing has got to scream with that .25 up front. I've seen this plane or a similar one at the field set up for electric power and was it neat. Not only that, there's parts support from Great Planes.

There's also a very detailed and comprehensive instruction manual, unlike that horrific mess I got with the Zero.

Hmm...

You know, this might be a do-er. I'll have to check Tower and see if my incentive coupon is still valid.

Hmm...

Retail therapy, anyone?

It's kindling.

I should have listened to the fellow who gave Project Zero to me. Our field has been the site of some really severe radio hits bad enough to trash two of his planes. The hit would send his planes into a hard left spiraling power dive from which there was no return.

It happened today. Second flight. On Project Zero. Same MO. All that work down the tubes. Complete rekit necessary and three of the five servos had their gears stripped. All this after grinning like a total idiot all through the first flight. I was running the engine rich as part of the recommended break-in, but that didn't stop it from flying absolutely fantastic. Just like a bigger, faster version of my E-flite P-47 with some really sensitive ailerons and far more rudder control just to keep things interesting. My radio doesn't have exponential, so I figured I could live with it. It really wanted to torque roll on takeoff and it was all too easy to overcompensate. On the other hand, rolls and loops were utterly gorgeous, albeit limited per the engine's break-in recommendations. I even got it to do a fairly nice knife edge with all that rudder, something that's flat impossible to do with the P-47.

I guess I could be philosophical and say that I crashed a free airplane...but I did spend a lot of money to get it airborne and more than a little bit of totally irretrievable time.

All this before breakfast, too.

I seriously found myself wondering whether or not I wanted...Continue Reading

As of exactly noon local time, Project Zero was finally completed! Man, that cowl was work!

In any event, all that's left to do is to fill the fuel tank, check the CG, plug in the receiver and reinstall the battery. I simply couldn't resist bolting on the wing so that I could photograph the plane and share the news.

Oh, and I will of course be rejoining the AMA at my earliest convenience. I really want to take advantage of the local club!

If anyone has the November '06 edition of Model Aviation, the club has a featured article since it hosted a statewide turbine meet. You'll agree it'll be worth the $15 a month to play there.

Enjoy the photos!

Since all of the airframe repairs were made to my Project Zero some time ago, the rest is comparatively straightforward.

However, I promised pix of the ongoing work and pix there shall be.

I can see why everyone raves about O.S. engines, including the guy at the hobby shop. Using the opportunity to not only rest my sprained ankle but to do some of the easier tasks necessary to finish the job, I soldered up a Sullivan Gold-N-Rod throttle cable and proceeded to do the preliminary break-in.

What a magnificent piece of engineering this .25 FX is!

I broke it in with a 9x6 prop but I'll be flying on a 10x5 since the 9" looks mighty small against the cowl. One of the freebies I was given along with the plane itself was a Master Airscrew 10x5. Lucked out on that one. Even with the 9x6 up front, that fuselage wanted to practically explode off of the field box. This engine is smooth, powerful, easy to start and is built like a Swiss watch.

It's down to only this:
  • Final trimming, painting and filling of extra holes in the cowl

    Drilling the access holes in the cowl for the mixture screw and glow plug

    Mounting the "Fueldot" fuel filler

    Double-checking the CG

I have a feeling this is going to be one fun ride.

While it's true that those of us who fiddle with R/C models occasionally get bitten by them (and I have scars on my right forearm to prove it), I may be one of the first...if not the first...to twist an ankle because of a model plane.

Thought I'd fly the combat plane one last time before dissecting it in order to add the landing gear. So, I wound up to do a "Hail Mary" throw with the thing...one, two, three steps forward...and my right foot came down wrong on a clump of crabgrass. Might have been the same clump that hung up the P-47 on landing the other day.

Time to do some weeding. Sweet revenge.

I almost forgot: I've mounted the new engine on "Project Zero," but hoo boy, do I still have a lot of work to do.

The engine is mounted on its new nylon mount in exactly the same place that the thing would have been mounted on the wooden mounts, but I had to trim the fuse to clear the muffler and (sadly) had to cut open one whole side of the cowl to accomodate same. After all that work to repair it, too. Thought I was gonna cry. Oh, I knew I'd have to trim that part, but it didn't make it any easier.

...unless you have to disassemble everything to make it right.

For instance:

The E-flite P-47 just got itself a new wing after three months of waiting. The factory told me that they were backordered. So, I've been tooling hither and yon across the sky with a wing that was damaged on its second flight by one of those dangblasted vinyl servo covers coming loose in flight. P-47 owners, you can no doubt relate.

Yesterday, sure as heck, one new cover popped off the new wing. Lost it in the field, but at least the wing didn't get damaged. Again:

Thankfully, I had a near-new spare with the double-sided tape intact, so on it went with a bit of Zap-a-Dap to help hold it down.

Naturally, the covers will have to come off. The adhesive holding the landing gear blocks are letting go after only two landings. They're impossible to remove when new. A little bit of impact is all it takes to loosen them.

So...why in HECK does that factory insist on doing stuff like that? In their attempt to save building time, the opposite is happening instead since each and every factory adhesive bond in that plane is substandard. The instructions even hint to that fact, suggesting that all hinges and the motor mount stick be checked. Naturally, they come right off in your hand, necessitating a cleanup of the old "gorilla snot" adhesive and reattachment of the part.

Result: Double the build time.

I hope that I can get that cover with the contact cement off without much trouble.

Grrr.....

No, I'm not predicting the apocalypse. Really.

It's just that I have everything I need to complete "Project Zero!" It's been a long and piecemeal process...a little bit here, a little bit there...but I expect this little sport plane to be back in the air within the next week.

To recap: "Project Zero" is a new "Zero Fighter 25S" ARF. A friend of mine bought it online through, I believe, nitroplanes.com. That's the only online source I could find, by the way. Anyway, he put it together with electric power and proceeded to clip another plane in midair a few seconds into its maiden flight. Rather than repair the exceedingly light damage, he elected to simply order another ARF. He gave me the damaged plane less electronics (but with the brand new, unused fuel tank) this past May. My plans were to rebuild it with glow power since the model can be equipped either way, and so I have. I've been working on it a little bit at a time since then, repairing damage to the wing, the internal structure of the fuselage, the canopy and the engine cowl. There was some damage done to the tail after the crash when something was dropped on it. That may have been the proverbial back-breaking straw. I've also been documenting the progress here on this blog.

So, the countdown has begun! Once this is done, I plan to hit my next project which will be my first kit. A Hobby Lobby Mini Telemaster waits patiently in my closet.

All told, this whole affair has set me back maybe $200, most of which went toward the engine and fuel. Not bad at all.

Stay tuned!

You know, there's something very satifying in taking a discarded machine and bringing it back to life.

I gotta tell ya: I'm feeling mighty satisfied right about now.

Burned much midnight oil last night without realizing it in my attempt to fully free up the crank and carb of a really old and completely gummed up Veco 19 that a gentleman had given me.

Once assembled with a glow plug, the compression felt like that of a new engine. Lots of bite.

So, I used my .25 combat plane fuselage as a test bench this morning, fueled it up, fired up the glow plug...and darned if it didn't run even without a pressurized tank.

FYI, the tank had to have some sort of ventilation. Woudn't run at all when I plugged off the line I normally use for pressure.

It doesn't like being run lean, it really doesn't like to idle (although it may be because the exhaust port is closing too far) and it's sputtering a bit on the top end. It also wants to flame out after about half a minute; I suspect that the carb gasket is contributing. That missing carb setscrew might be contributing as well. I couldn't really adjust the mixture screw when it was running since it happens to be on the same side as the exhaust port. Owie. I didn't pull the pressure line off of the tank, so the engine might have been "sucking through a straw," as it were.

What I do know is this: An engine that likely dates back to the Kennedy administration (or earlier) and which languished in a box of junk for heaven knows how many years (or decades) is a viable, operating machine once more.

There may very well be a vintage project in that engine's near future.

I just can't leave well enough alone.

Here I was, all ready to incorporate an old Veco 19 as part of a wallhanging, when I decided to start tinkering with the thing.

Before leaving on vacation, I'd managed to get the crank to turn (albeit not too well) and I also managed to free up the exhaust baffle.

Tonight, I got serious.

Off came the top of the head and off came the carb. Some electric motor spray, WD-40 and VB penetrating lube freed the crank from its sludgy prison. Turns nice and easy.

Best part is, the internals look to be in great shape.

Even with key parts removed, the pop-suck-pop of that little engine was nice and strong. There's no scoring in the cylinder, no play in the crank bushings and the piston looks good as well as viewed through the exhaust baffle. There was a bit of crud on the top of the piston, but only a bit. Maybe someone wanted to upgrade to a .25, so this .19 just got set aside.

So far, the only hangups are the carb and one of the carb's setscrews. The carb has been dissected and is currently in the opening phases of a two-day spa treatment in VB penetrating oil. Like the old O.S. that I just resurrected, the throttle barrel is stuck at WOT. As far as the setscrew is concerned...I lost it! Somewhere between the back of the house and the front yard, one of those original parts was lost. I can easily replace it, but it's the thought of losing an original part that steams my fleckmans.

Here's where you Veco...Continue Reading

Tell you all what: Ten days in Hawaii is enough to mellow even the most messed-up mind. Kinda like mine was before I left. I may post a picture or two. First time there; it won't be the last.

Still, it was nice to return to the toys.

I went to the indie hobby shop today to order up a new O.S. .25 FX for "Project Zero" and I bought a few small items it needs in order to be finished.

Now, when they say to "measure twice and cut once," they aren't kidding.

I bought a beautiful combination power switch and battery charger receptacle made by JR. It may be beautiful, but it sure as heck is big. No place to mount it on the inside where it won't be seen and it'll ruin the scale effect on the outside. On top of all that, it would have made that small space in the fuselage even smaller. The factory cutout is for a very small switch. The JR goes back tomorrow and I'll apply the store credit toward the engine.

I also discovered that the wooden engine/motor mounts from the factory are too wide for a .25 engine. I'm glad that I had the foresight to remove the old O.S. Max FP .25 from the homebuilt combat plane I was given to use as a mock-up. Looks like I'll be adding an off-the-shelf nylon mount after all. The plane's instruction manual is downright useless as more than a basic guide for mounting the engine. I just need to get 105mm between the firewall and the back of the prop and all should be well. The slots on the firewall for the...Continue Reading

Well, I can take another project off my to-do list.

The RC10GT went back together last night and got driven this afternoon. It started with a couple of tugs of the pull start and only needed some minor adjustments of the idle and throttle trim. It went screaming down the street faster than I recall it ever having run, trailing that wonderful nitro exhaust flume behind it. Ran a tank of fuel through it and I was smiling the whole time. I thought it best to run it without the body for testing purposes, but that's a small gripe.

That was a nice feeling; it made up for a minor mishap with my P-47.

It caught a clump of crabgrass upon landing out at the field this morning which yanked off the right landing gear wheel. When the tail slammed back down, it broke the elevator.

Oh, well. A bit of glue and the elevator's good as new. I had a spare wheel spacer on hand from my crashed P-47 (I'd lost the original at the field) and I installed a couple of proper metal wheel retainers while I was at it. Lost the little black plastic wheel retainer, too. This isn't a biggie since I'd been meaning to lose the plastic retainers anyway.

Taking things easy for a couple of weeks. "Project Zero" will be completed soon afterwards and the old combat plane will be wearing landing gear from an E-flite Mini Brio plus a DU-BRO tail skid since I'm tired of having to restart the engine after every landing. I'm also picking up a couple of 7.2v ni-cad packs and a machine-wound modified motor for my old and long-unused Team Losi LX-T truck which had been modified for onroad before I even bought it. In fact, it was a record holder at the track it used to race at and it drives like it's on rails. See you all soon!

Ah, what a wonder this internet thing is.

A bit of research regarding the starting and running problems an RC10GT RTR has been suffering turned up some interesting causes.

Chief among those is fuel tubing.

Now, I know that the stuff doesn't last forever. Just look at my last post; I seemed to know it then. To reiterate, it doesn't last that long and all it takes are a couple of microscopic pinholes to develop while running to cause the whole schmutz to come to a screeching halt. Who'd a-thunk that?

New fuel tubing: Check.

Nitro guy at the local hobby shop pointed out a little something on that engine that I hadn't noticed, specifically a bit of grunge around the base of the carb which escaped the blast of cleaning spray. Bad o-ring? Possibly.

New o-rings throughout dissected carb: Check.

I'm taking no chances with that old fuel tank. I don't know if the fuel residue that was in it means either a leak or a deteriorated filler cap seal, but I figure a new tank is cheap insurance.

New tank: Out of stock at local hobby shop; checking franchised shop on the morrow.

Engine is ready to go back in. Report forthcoming!

In my last post, I mentioned that the videocassette shipped with my son's Team Associated RC10GT RTR said that the engine could be started from underneath with an airplane starter against the flywheel.

Owner of the local hobby shop said he tried that routine. Doesn't work.

On the other hand, I'm inclined to take a closer look at a Sullivan Tiger Drive starter. Since my son has a rather powerful Dewalt cordless drill that would spin that little engine rather nicely, I think that might be the economical way to go as opposed to a starter box, but we'll see.

This doesn't immediately solve my starting and running problems, though.

Last night, I pulled the engine and set everything exactly to the factory recommendations. Once I either tighten up or replace the flywheel and put everything back together, I'll at least have a baseline reference to go by.

As a result of all this nitro noodling, I did some R/C Zen this morning. Found my center with some electric flight. Banged sticks with the Blade CP and then I put the P-47 Thunderbolt through its paces. I even managed to loop the chopper...but ain't no way I'll try that again anytime soon without symmetrical blades. Very, um, dramatic. Fun, though. Nice and clean as well. Not as fast as that little .25 combat plane, but nice and clean.

Oh, and after doing a bit more research, the problem might be ridiculously simple: Silicone fuel tubing has a tendency to develop pinholes, sometimes really tiny ones. Engine temp goes up, fuel level goes down, bye bye pressure.

Cheap fix and I was going to buy some anyway since I wasn't too happy with the condition of the tubing that was on the truck when I started in.

With all the fun I've had as of late bringing two long-neglected nitro models back to roaring and thunderous life, I decided to roll up my sleeves and attack yet another nitro project that got kicked to the corner a long time ago...and it isn't even mine.

In today's spotlight, one out-of-production Team Associated RC10GT RTR, complete with blister-inducing pull start.

Now, before I continue, if you ever wish to see the most amateurish video production ever produced for enclosure with a world-class product, get hold of the videocassette of Cliff Lett and Gene Husting explaining how to tune the engine. The jump cuts alone are worth the price of admission. I endured it last night before attempting to play with the truck today.

My wife and I gave this to our son about three Christmases ago as a way of making up for the fiasco he'd endured trying to get his Savage 25 running properly (see an earlier post to learn of its fate). He's since moved out but has expressed no real desire for me to send the RC10 his way. In fact, he'd like me to keep it here since he has no room in his new place.

Wonderful. Another orphan.

The issue with this little monster is typical: It starts, it runs, it stalls and becomes impossible to restart even though it doesn't appear to be overheating. As a result, this truck has logged very little runtime.

So, off came the fuel tank with its old, stale fuel sloshing at the bottom and out came the nitro car spray cleaner. Truck is...Continue Reading

I just got back from the usual Sunday fly-in. Not a huge turnout since a few folks are on vacation, but I did meet a couple of new "members" of our little "club."

This was a tattooed and very friendly father and son duo who were given a well-used and crashed Global Hobbies Right Flyer .40 trainer with accessories. They did an admirable job of getting it back together, but oh, what a strange looking little bird it was in its spray-painted blue and silver livery. With hand-drawn flames at the nose, yet.

Poor guys were trying to get the engine started but to no avail. They claimed that it ran fine at home, but not even so much as a sputter at the field.

The electric drill they were using to spin the prop was rather low on juice as were all of their glow ignitors. I gave the prop a spin and I have to tell you, there wasn't a whole heck of a lot of compression biting back.

Keep in mind that they brought the plane to the field in pretty much the condition they got it. This wouldn't be so alarming if not for the fact that the radio wasn't hooked up properly. I noticed this when working the throttle...and it was working backwards. "Do you prefer to fly with the throttle lever reversed like this," asked I.

"No, that's the way we got it," was the reply.

Twiddling other levers revealed that the ailerons were on channel four and the rudder on channel one. Only the elevator was responding properly.

As it turned out,...Continue Reading
