The A2826-M 1100Kv motor and stick mount from the Gorilla Bob's store at the AMA expo are ready to rock at the front of the little Thunder Tiger Bearcat foamie. The motor, mount and my temporary 40A ESC are in place, I've installed a receiver and once I do up the control throws and expo and install the 8x6E APC prop, I'm ready.
I've spent a bit more money on it than I might have otherwise done, but the initial tests with brushless power were very encouraging.
The wing is very stiff, but it isn't reinforced. Once I'm satisfied that it flies well, I'll run a carbon fiber spar underneath.
Once this little project is complete, I want to finish up a project which has long been dormant. It's a kit built Great Planes .46 Ultimate biplane given to me a few years ago. I blogged about it at the time. It was done as an electric, suffered slight damage in a crash and the owner gave it to a friend of mine who gave it to me. The airframe has long since been repaired, but no power or electronics are installed.
This brings up some interesting possibilities. I can either use the O.S. or K&B engines I have in mind or follow suit and go electric.
OK, so it's almost a week late in coming, but I have to say that my grandson and I had a marvelous time at the AMA last week. Always fun to see fellow hobbyists and to reconnect with many of the vendors.
Visiting the Pegasus Hobbies booth reminded me of the little Thunder Tiger Bearcat park flyer I bought last year and about which I've blogged on and off since. Easy to see why; they were offering more of those little RTFs for sale once more!
So, thought I, why not get mine flying once and for all? I think it had all of three flights to its credit and not all of them successful.
Found an 1100Kv motor, stick mount and APC prop for the proverbial song right there at the expo from the Gorilla Bob's stand. The 18A ESC I was using is too small for this combo, but I'm going to give it a go with a 40A unit. If all goes well, I'll put a 30A control in the little booger. Should've picked up an inexpensive ESC at the time, but oh well.
Will be blogging once more once I get it flying. There's just something about the challenge this little foamie has presented which makes me want to keep on keeping on with it.
Just sitting by the computer waiting for the new year to arrive. When I saw that I might be one of the first to blog this new year - or one of the last to blog in the old - I wanted to take the opportunity to wish everyone in the RCGroups.com family a happy, prosperous and blessed new year. Some great reviews are coming down the pike and I invite everyone to keep checking in over at the electric flight page.
I received one of these entry level brushless quads today as an official RCGroups.com review sample. It must have either been a demo unit or it was tested before being shipped from China. In any event, it came with no manual.
Binding the transmitter and the model isn't an issue, but I can't figure out how to arm it. Anyone else have one of these and who would be kind enough to please tell me how to arm it?
Yup, one of this site's biggest sponsors is getting a head start with some incredible deals on already low priced hobby goodies. Since I was asked if I'd be kind enough to share this good news both here and other social media, heck, who am I to say no?
Happy Thanksgiving to everyone here in the US and yes, Merry Christmas to the rest of the world!
Trouble is, I wadded it in due to pilot error, hence the bit about "the first part." HobbyKing, a major sponsor of this site and a great bunch of guys to boot, sent me a new Super-G to use in the second part of the review and even a Durafly Auto-G2 for practice!
So, practice I did. The president of the R/C club did the honors of the maiden flight of the Auto-G2 and got it trimmed. I flew the second flight.
Tell you what: Autogyros are definitely not airplanes nor are they helicopters, but let me say that I really learned my lesson with the Super-G. This unusual, exotic model was fun to fly!
Here's the funny thing: The club president had never flown an autogyro prior to yesterday! Still, he did a fantastic job of getting the Auto-G2 dialed in.
I'll be putting in a lot of stick time before proceeding with the assembly and flight of the replacement Super-G. I'm definitely going to add some fluorescent orange and green tape to the fuselage to make it easier to see, even with 20/15 distance vision.
Part two of the review will concentrate on the flight characteristics of the Super-G.
I've been doing official reviews for this site for a long time, but one upcoming review in particular has been a big undertaking, so much so that I split the reviews of both an airframe and engine in two parts.
The airframe is the large scale Nitroplanes Pitts Model 12 biplane with a 20cc gas engine, J'tec Pitts muffler and 17x6 prop from Valley View RC up front, held in place by most of an Aeroworks mounting kit. Guidance is via an Airtronics SD-10GS radio and the Pitts Python graphics are from none other than Callie Soden at Callie Graphics.
The second parts of each review should be ready within a couple of weeks; I wasn't able to get video of the maiden flight earlier today. My club's president did the honors of the maiden flight and yours truly snapped some pictures.
All I can say is, this combo simply rocks. Full details soon to come here at RCGroups and Flyinggiants.com.
Half the fun of this site is meeting new users. Case in point: Joe Kwok, aka "Hansondiandian" who is the "Joe" half of Joe-Hanson Aircraft Co. in Texas. Joe is a twelfth-grader who has been designing and building model aircraft for the last several years.
I'd contacted Joe via a private message soon after he'd blogged about his new hand-cut foam sheet kits. As a result, I received a kit to assemble and test for an upcoming RCGroups.com review. It wasn't until later that I'd learned just how young this model's designer really is.
I couldn't send this sample photo via a private message, so I'm sharing it here on the blogs. I had intended to fly it today, but two things got in the way. One, it was kind of windy. Two, I left my radio at home.
This was shot on the back of a flatbed utility trailer parked at a nondenominational church which allows electric flight over its parade grounds. It's a site I often use as part of testing models for the review process.
So, please welcome the loftily named Joe-Hanson Aircraft Company JH-21A Vesper II utility airplane. Designed to haul a small camera or FPV system aloft, I'll be flying this (hopefully tomorrow) as a fun flyer. All of the electrics are courtesy of Global Hobby Distributors.
Keep an eye on the electric flight page for all the details!
After a few emails to and from my contact at Gearbest.com, I have a couple of RTF quads which are about to be officially reviewed for RCG.
One is just too darn cute.
It's the Floureon FX-10, the world's smallest quadcopter. It's so tiny that it's actually stored in the transmitter!
No pix yet, but I'll have a bunch in the review.
Looking at the other end of the size scale, my Nitroplanes Pitts Model 12 biplane with its Valley View RC 20cc gas engine is nearly ready for its first flights. I've already written reviews of my initial impressions of both the airframe and engine with the latter currently showcased both here and at Flyinggiants.com.
How tiny is the FX-10, you might ask?
Its diameter is just a bit larger than that of the prop retaining washer on the 20cc engine.
Large and small, indeed. Stay tuned to the electric flight, large scale and gas power pages here at RCG!
That, by the way, is a quote from Allen Saunders and not John Lennon. Lennon used the quote in the lyrics of "Beautiful Boy," one of his last compositions.
That said, I haven't made any progress on the little Thunder Tiger Bearcat since last we met here on the blogs. That missing motor bearing might be an unusual 3.17mm version and there were none to be found at the hobby shop. I'm just going to install an E-flite and be done with it soon.
Lots of professional stuff has kept me busy, but in a remarkably nice way. Details to follow.
In the meantime: Lots of great hobby stuff is on its way to the electric flight review pages! I'm covering the HobbyKing Super-G autogyro, the HobbyKing micro B-17 and the Joe-Hanson Vesper II utility airplane. The latter is a foam board model designed and produced by an RCGroups.com user, namely "Hansondiandian" out of Texas. It's a very utilitarian model which can be used as an FPV platform, camera platform or even an aileron trainer. I'm simply waiting for parts and supplies to complete all three models.
Watch this page and the electric flight page for updates!
I admit it. I enjoy a good challenge, especially where getting my money's worth is concerned.
To wit, the continuing saga of the little Bearcat park flyer which has been the subject of my last few blog postings.
I sent it up for a test flight and as luck would have it, the elevator was way out of trim. Far too much up, which wasn't an issue on the previous flight.
This, of course, made it difficult to fly...
I brought it around for a landing, bounced the landing and broke what was left of the original wooden motor mount. A close inspection revealed that the plastic factory motor adapter was damaged from the previous mishap.
Another thing which was readily apparent was far too aggressive a prop for the old motor I installed as a temporary measure. More on that in a moment. What to do? The answer came in the guise of the parts removed from the Flyzone Cessna which had given up some of its components.
I already had most of what I needed from an E-flite firewall stick mount adapter system; the mount itself was cut down to fit the Cessna and was too short for the Bearcat.
Five bucks later, I had the adapter and the strongest possible motor mount. It looks like a factory setup, in fact.
Another test flight, another mishap. The Bearcat was ballistic! Maybe too much so. One of the screws holding the prop adapter shaft worked loose, causing the shaft to cock over to one side. And boy, was that motor hot. As I'd pointed out, too much prop on a high-revving motor with an unknown Kv rating. That's what I get for not checking the setup with a wattmeter beforehand.
Conclusion: The airframe is dialed in. I just have to get the other motor back from the hobby shop and I'll be in business.
The new FMS Kawasaki Ki-61 High Speed PNP from Diamond Hobby is a blast!
An official RCGroups.com review is waiting in the wings for public viewing. Stay tuned!
In the meantime, more weirdness regarding that doggoned little Thunder Tiger Bearcat.
I swung by Pegasus Hobbies a couple of weekends ago since I happened to be in the area. Tony at the airplane desk is a terrific help. He sold me a brand new cowl and told me that he had a lot of those planes on hand for parts. Cool!
On went the cowl, up went the Bearcat.
It flew great, but the elevator was acting twitchy. I brought it in, added some more expo, took off and all seemed well for the first few seconds.
That's when the motor's endbell decided to part company with the rest of the motor.
It isn't often one has to do a dead stick landing with an electric, but I did. Good one, too. No damage other than some minor breakage of the wooden motor mount due to the forces involved.
Everything is back together, but the motor is missing a bearing. I've left it with a buddy at the hobby shop who'll check the parts bin for a replacement.
I also have a no-name brushless outrunner I used to use on my ancient (and recently dissected and discarded) E-flite Blade CP. I've ordered a prop adapter; we'll see how this one works.
Wouldn't you know it? The battery compartment door for my OrangeRx transmitter seems to be lost forever. I went to the field today (with a couple of planes in tow, natch) so that I could look for it.
However, I did happen to see a new FMS P-40 high speed like the one I'd reviewed for this very site! Deja vu! The new owner is still somewhat nervous about flying it, but one of the club's flight instructors was on hand and he declared it to be a blast. This from a guy who was zipping a 150 mph Habu all over the place. I happened to mention that I'd soon be receiving a new FMS Kawasaki Ki-61 High Speed.
When I got home, sure as heck, that new Ki-61 was waiting at the door. Not deja vu, but pretty good prescience, no? This is one highly anticipated model and I'll be giving it the full RCGroups.com review treatment, so please stay tuned!
Yup, one of those nagging little voices tried to tell me something important and I ignored it.
This past Sunday, I had the Thunder Tiger Bearcat with me along with some other models.
I never really trusted the bizarre factory aileron hinges which consisted of decidedly unsticky clear tape across the tops of the wing and ailerons.
Meh. Should be fine. Checked the controls, lined up for takeoff, gave it the gas...
It came around hard left and crashed into the flight line. Upon removal of the tape, it was barely sticky enough to lift the paint and yes, those horrible quality factory strips were all that were serving as hinges. The motor mount broke, the cowl was crushed, the propeller broken, there were surprisingly few and clean breaks in the fuselage with no crushing and the right horizontal stab was snapped off.
A quick assessment of the damage showed me that it was repairable, so out came the epoxy, CA and paint and an old metal pushrod cut into reinforcement spars when I got home. I was even able to pop the cowl back in place and tape it from inside. I'll replace it soon if Pegasus Hobbies has it in stock. For now, it's doable.
I picked up some E-flite park flyer CA hinges yesterday and I properly hinged the ailerons this morning. I also found that the thin plastic plates atop the ailerons which were supposed to hold the torque rods in place were held down by little more than some weird, brittle glue.
The Testors Insignia Blue Model Master acrylic paint I used is at least a close match to the factory finish, if slightly darker. The prop should arrive at the hobby shop later today. In the meantime, the end result is nicely repaired, cosmetically acceptable and perhaps most importantly, the ailerons are properly hinged with the torque rod plates epoxied in place.
If I'd listened to that nagging voice telling me to re-hinge the ailerons, I would have saved myself from a lot of work.
Today was just one of those days which felt good. I got some stick time this morning with some recent review subjects, namely the HobbyKing DC-3, FMS/Diamond Hobby P-40 and the Nitroplanes Dynam Bf-109.
I think I have the tail wheel situation nearly dialed out on the DC-3. Still a bit wobbly, but taking off with flaps lowered allowed it to track much better. However, the flap switch is in a terrible position above the throttle stick. Trying to raise the flaps nearly caused a crash since I was having to really grope for the switch without taking my hands off of the stick at the same time.
I'll be mixing the flaps and the retracts on the radio before I take it up again.
That P-40 is one screaming fast bit of foam. The batteries are now somewhat seasoned and the punch is just incredible. Chalk up a winner to DIamond Hobby and Predator batteries!
Maybe I'm just spoiled after blasting the P-40 at nearly 100 MPH, but the Bf-109 feels, well, slow. That's with a Master Aircsrew prop on an otherwise stock bird. It flies beautifully and with no bad habits whatsoever. So, the perceived lack of speed isn't a problem. I just have to remember not to fly it after low passes o'er yonder runway at triple-digit speeds with the P-40.
Just got through watching "The Ten Commandments," something of an Easter tradition for my wife and I. Cecil B. DeMille was a genius.
Happy Easter, all. Christmas may get the hype, but this is the holiday which matters most. Back to work tomorrow!
My buddy wasn't kidding when he told me that his own Thunder Tiger Bearcat park flyer was a sweetie with brushless power.
I took it with me this past Sunday along with some models I'm reviewing for RCGroups. I needed to get video and I thought this would be the perfect time to fly the Bearcat as well, this time with a computerized radio.
To be sure, it needed trimming, but once trimmed, what a fun and fast little plane. It still wanted to nose over on landing, but that was simply due to the landing gear being bent too far backwards. Once that was fixed, boom. Perfect three-pointers.
Was it worth the money? I think so. I could have saved ten bucks by buying the receiver-ready version, but then, what would I have done without the 27MHz radio system, brushed motor, gearbox and NiMH batteries languishing in a drawer?
If anyone wants the unloved radio and power stuff, please feel free to drop me a PM. It works, it's new but nearly obsolete and I will likely never use it again.
The Thunder Tiger Bearcat park flyer I've been blogging about had, as I suspected, far too much control surface throw and no expo which meant some really gut-wrenching moments after takeoff.
Hoo boy, did it boogie when I settled down on the sticks. Fast, smooth and fun.
In all honesty, I can't help but wonder how many folks might have picked one up as a first plane and who soon discovered that flying it with the supplied radio and power system was unlikely to happen.
Result: Scores of disgusted hobbyists who lost interest in model aviation then and there.
The modified version is a whole 'nother deal.
That little Suppo outrunner pulled it with real authority as a Bearcat should and it glided forever on final approach. The touchy elevator made it difficult to flare and it came down kind of hard, but there was no damage other than a scratched cowl when it nosed over.
I do believe that I'll be flying the whee out of that little sleeper for a long time to come, that is, once I set it up on a computerized radio. The transplant was a raging success!
Now all I have to do is figure out what the heck I'm going to do with the original radio, batteries and motor...anyone?
