Just blathering....

The more I fly this plane, the more I love how it feels to be in command of something that looks so great, sounds so powerful, and flies with so much authority in the sky! This is one keeper of a plane!

There is a definite connection between me and this plane! I suppose it's easy to say when the power system (it's heart) was spec'd by myself, with the help of a few key people in the Sundowner 50 Fast setup thread. You know who you are! It has gobs of power, and is very fast in the sky for such a big plane... We estimate about +120mph flat out, 130mph in a shallow dive. The presence of this big plane at speed is impressive!

As the season is winding down up here in Canada, it will be sad to have to put this one away for hibernation, but I just can't see myself out there at -30c flying this one with skis

Here are some more more photos of it courtesy of Kevin B. our club photographer

Last weekend I had a slight fly away with my newly revamped P-47 Jug. It is comprised of a new air frame, Turnigy G25 motor, Turnigy 60A Plush ESC, and Nanotech 4s 2650 batteries, swinging a 9.5x7.5 prop. I had a few flight in under this new power system and it displayed lots of power! It was the 3rd flight and I ran it mostly wide open. I had also switch over to 10.5x9 prop for the increased speed. It wasn't really apparent, however I suspect it drew a lot more amps. I should have measured it before I flew it, but you know how it is...

So My 6 minute timer went off, after a mainly WOT flight from start to stop, I was flying it out to swing around for the landing, when I felt it was losing throttle response, I thought sure, my batteries are out.. But then it just continued to fly straight away with no radio response either.... I must have lost it all as it was pretty far away when I made the walk of shame out to it after it crash landed.

It had landed on the left wing tip, causing it to crack along the chord , the cowl was busted up as was the prop... Other than that, it was looking pretty good and did seem to display throttle and control response when I had it in hand. Anyway, lesson here is reduce the timer to 5 mins, and be sure to measure any high perf props should I adjust again.

I took it home, glued it it up and replaced what needed replacement. While I was there I decided it was time to change out the Snorting Bull Motif to the Elsie LiL Butch...Continue Reading

After supper the wind had died down significantly so I quickly packed up the MX and headed out to the field... The conditions were beautiful, as the autumn sun was setting.

I quickly assembled the MX and put her to the air. Upon take off I noticed it seemed really tail heavy so I made one quick circuit, landed her and adjusted the CG. I pushed the batteries forward by a good 2 inches and took off again.

It still seemed somewhat tail heavy, but it was certainly better. I took her up 3 mistakes high and started to make trim adjustments. I really had to trim in lots of down elevator so she would stop climbing like a home sick puppy. A bit of left aileron trim and I think that was it. One thing I noticed was this thing really responds to trim adjustments. One or two ticks one way on the aileron or elevator would have the plane pitching in that direction quickly..

Once settled, I started to just fly it around and get use to how it felt. It certainly was not what I was expecting... Recently I've been flying fast moving planes, and this one took me by surprise in that it doesn't really fly fast, but man can it ever stay up in the air at any speed. It's like a radio control kite or something... Even when I landed it, it seemed to take forever to float down to the ground. The difference it would seem is everything I have been flying recently depends on speed to fly, where as the Extra MX doesn't seem to need speed at all to fly, it just needs air under it`s...Continue Reading

I packed up my Extra MX and PZ P-51 and headed to the flying field, even though it felt much too windy out, I had to see what it was like... As I approached the flying field at about 12:00, I seen nobody was there. This should have been my first clue. As I was unlocking the gate, I suspected nobody had been at the field today there were no tracks in. It had rained all day yesterday, so the road in was untraveled & squishy. I had the truck in 4 wheel drive, and it was still sort of squirming about.

As I was unpacking, the Extra MX and P-51 was being blown around by the wind. A quick measurement showed the conditions at the field were between 30 &40 km/h wind from the south west. I knew I probably wasn't going to fly the Extra MX, but planed to take the P-51 up as that is my go to plane no matter what.

I assembled the Extra MX, just in case, however as I assembled I was struggling to keep the pieces, bags and parts in check and from blowing away.... I then knew I would not fly the MX, as I just didn't want to risk it.

I finished assembly, took a few pictures, and then put the P-51 in the air. This plane is a dream to fly regardless of the conditions. I think because I'm so relaxed with it, it always inspires confidence. Still, I flew only one pack and decided it was time to call it quits, and try again another day... Like Clint Eastwood said "A Mans Gotta know his limitations...."...Continue Reading

After the mid air collision from last week, I was able to get the Jug rebuild with a new air frame. The old fuselage was almost intact, with the exception for the plastic fire wall that had a bunch of cracks in it. I decided to just order the entire airframe and replace the guts, save the old fuse and replace the firewall for a secondary P-47 project.

The New P-47 uses a Turnigy G25 870 kV motor, Turnigy Plush 60A ESC, 4s 2650 mah, 25c Lipo, swinging the stock 9.5 x 7.5 prop. The calculated prop speed is 82 MPH. Flying it today I would say this set up has given the P-47 new life. Before with the stock BL-15 and 3s set-up, it was adequate, but it really didn;t climb well, and it was underpowered. With this new set up ti flys much faster and does seem to have unlimited vertical.

I left the stock paint scheme for now as I will paint up the old fuselage as a winter project.

On a different front, the Precision Aerobatics Extra MX is coming together, and hope fully I may get to fly her soon. I'm a bit apprehensive about flying this unit as every time I fly a 3D plane in the sims, I crash lots.. The amount of control and the insane angles a person gets with one of these planes is mind blowing! I definitely will need to tone down the throws and increase the expo for this one.

One thing about the construction of this kit it the amount of little things that a constructor needs to do to get it ready to fly. It's small fiddly stuff, but it has been satisfying.....Continue Reading

It was a successful maiden flight! The plane flew very well and is impressive in sound and in the air. It drew a lot of comments just in throttle ups on the pad. Many said it sounds very powerful! Another exclaimed "Yippe Ky Yay, MF"

The plane lifted off a lot faster than I had expected it would. My take of was a bit shaky, but really in spite of it, I felt in control. I though it would use more run way when suddenly it lifted off... I think I throttled back a touch, but then realized what was going on, throttle up, and adjusted for the wing tips rolling from side to side (you'll see it in the video). After review of it I think I do not need to hold full up elevator withthis plane as I do with my others. It's become a bad habit to hold full up elevator with my Parkzone P-47 to prevent nose ins, as well as my Pogo to keep the tail wheel planted to prevent left torque steer.

Once in the air it was smooth..... and fast!! I didn't really open it up too much at first as I wanted to get a feel for the plane. After I did, it was impressive! It has a nice whistle of wind over and through it that makes it so cool sounding. The Scorpion motor was sounding great too! Because the airspace was busy, I was cautious, especially as I'm a bit gun shy from my mid air collision the day before.

I found the rates set very well... The elevator could use some reduction in throw as pulling full amounts makes the plane almost flip over unnaturally. However the...Continue Reading

I was involved with my first Mid Air collision today that resulted in a spectacular explosion of parts in the air! I wished somebody would have captured this on video or pictures. regardless, it will be one of those stories that gets better as time progresses.

I was flying along the flight line at about 30 feet, when all of a sudden I seen a plane in my path. It happened so quick I didn't have time to even react, as I 'm sure we were both moving at WOT. As most times you sort of think you may miss each other and that you are not as close as you think, however with in this split second thought, it happened so fast.... It was a head on that produced a most impressive "SMACK". "CRUNCH"

I called out "Planes coming down on to the field" as there where others still the air. I watched helplessly as my plane tumbled to the ground. Lucky all the parts came down in the same area. In fact my pilot even ejected! LOL

Greg the other party had to collect many parts on the field, as his plane was balsa, where as mine was foam. In the end I could rebuild mine. His is a total write off (as he said). My wing could be fixed, but I think I will just get a new one. The fuse was intact (so I though), however upon inspection at home, the motor mount is cracked pretty bad. So I may as well get a new fuse too. They have a complete Air frame kit I have already ordered.

It was a day of carnage as others where having problems as well. Must have been the great sunshine and non existent wind

After getting a set of custom wing bags from the PA Extra MX "Bling Package", I decided it was time to get the wing bags made for the Sundowner 50.

I made it out of a roll of Reflectix bought at Home Depot. Almost as nice as the PA Extra MX wing bags from the "Bling Package"... Okay maybe not, but they are custom made for the SD 50, holding the Wing tube in the corner, top flap secured with Velcro tabs and comes with carry strap that matched the plane

Lately I have been flying my Pogo LR-1A the most as I find it's just a blast to fly. I absolutely love that plane! I have been getting close to getting the Sundowner 50 in the air, however I'm still waiting for the external CC 10 A BEC to arrive and some other bits. I did finally secure an APC 12x12e prop, however I also have some TGS 12x12 and 12x10 props coming as well.

So... I was in Calgary for the weekend and visited PM Hobby Craft, apparently the largest RC hobby store in Canada. I'm not sure if this is true, but it is time well wasted wandering through the store looking at all the inventory

My first trip there I walked out with only a few items, foam putty repair material, 12x12e APC prop for the Sundowner, a new Radio strap and some landing gear covers for my ParkZone P-47. But I did have plans for something, but I couldn't decide... It was over supper that I made my choice....

I went the next day and picked up a Precision Aerobatics Extra MX Kit. I have been wanting one of these since I started flying and I though it was time. I ended up getting the Airframe kit with the iPAs Power Package, and the optional "Bling Kit" as well as a Spektrum 6210 Rx to finish it off. I thought I may as well get everything I needed to get the plane in the air, as the season is nearly over and it would be nice to get at least a flight or two in before winter hits Getting the iPAs Power Option saves me form having to wade through, source and plan the...Continue Reading

I installed my rudder and elevator servos last night and sonnofagun if the control rods they give you aren't different lengths! I installed my elevator first, then went to install the rudder and realized I use the longest rod and now the rudder rod is too short... DOH!

In other news.. I installed the pilot and cut a sheet of plastic for under him. Something about the head on a stick look I was not digging. I have not finished the front of the cockpit yet as I may try to come up with an instrument panel, or not we'll see.

Checked the CG and as mentioned earlier int he Sundowner thread, my airplane also requires the batteries to be mounted as far back as possible. They are against the fibreglass wing tube, and it's still slightly nose heavy, but should be close enough. I will need another extension cord for the ESC to Rx as I had to move the Rx back.

Well, if it wasn't for a too short of a rudder control rod, and a lack of proper propeller, the SD-50 would be ready to maiden.... Darn Stat Holiday making a day of rest

So I took the Sundowner out for it first light of day for some pictures anyway. This is one heavy plane at what I estimate to be ~10lbs

I'm really looking forward to this one! Planning and building this airplane model reminded me of my Hot Rod'ding days of full sized cars. I can see me wanting a few more of these!

All the main parts have arrived to start construction of the Sundowner 50. I started with aileron servo trays. They required gluing blocks to the tray to mount the servos. After the epoxy was setting I though to myself why not use servo tape...? I then read on the Hi-Performance Forum that many do just glue the servos to the tray. Other forum members that have been helping me out also said they just glue the servos to the tray as well. Seeing as I already had the block glued in place I decided to use them, but I also added servo tape to make it more secure...

Once the wings and linkage were done I then turned to the power system. I had to cut out the cooling holes in the firewall area and cut the exit hole in the ultracote covering.

Then it was time for the Scorpion motor to meet it's home! It fit beautifully, and the standoffs will not required modification. The cowl spacing looked great! I will need to come up with a better solution to position the cowl with the set screws. I had put grommets in the cowl holes to prevent scratching of the cowl, however I need something more positive to position and immobilize the cowl.

The ESC is indicated to be mounted on the underside of the firewall box. I suppose this is a good place as it's in the cooling air stream.

That's it for tonight...

My RC club "Hub City Radio Control Club" Hosted a pylon race the had competitors form Calgary and Edmonton. It was a greta event and the weather was excellent. It was a lot of fun and I was thrilled to see the Q-40 planes fling at 200 MPH.

Here is a video of one of the heats I shot with a Go Pro between Plyon 2 & 3. I was judging on Pylon 3. Go Full Frame to catch the action!

Q40 Randys Heat (3 min 16 sec)

I have started to pre assemble the Sundowner 50. I have ordered all the parts required to make this plane fly and I think it's going to be a gooder. With The help of forum members on the Sundowner 50 Fast Setups I think I will have a +120 MPH machine! Which I think is pretty impressive given the size of this plane.

Power System:
  • Scorpion S4025-12 (440kV) motor
  • Castle Creation Phoenix Ice 100A ESC
  • 4000mah 25c 8s Nanotech LiPos
  • Spektrum AR6210 DSMX 6ch Rx with Sat Rx
  • Hyperion FMD Atlas DS -20 Servos - Elevator and Rudder
  • Hyperion FMD Atlas DS-16 Servos - Ailerons
  • APC 12x10 Prop to start with then step up to 12x12

My understanding is this is a very well mannered airplane, so I'm looking forward to it. More than anything I'm looking forward to the presence this size of plane has in the sky, the blistering power and speed is just a bonus

So the first maiden flight I handed over to John a club expert. I wanted him to check it out and make sure I built it OK, and that it flew alright. John was impressed very much, and said it made him eager to finish his Toni EF-1. Plus I had to get pictures

Later I flew it and I must say it's very smooth and does handle like it's on rails. It pretty quick, even with this 8x6e prop. Takes offs were excellent and we couldn't understand the bad rap this plane gets on torque rolls. Mind you John said it's different when it's a race, and everyone is trying to get off the line at full throttle. Plus the 8x8 prop most likely changes the characteristics of this plane. I was wishing I would have brought the 8x8 as well....

The sound of this airplane is awesome at speed and while coasting. What was freaky eerie was taking it up high, hammer heading it over with no throttle, and letting the plane dive to earth at speed with no power. The sound of the air as it rushes by is sweet! Knife edges with this plane is effortless, it does them with out even trying it seems.

I love the look of this plane and how it handles in the air, it looks and handles so surgically precise in flight. The sound is great too!

After much time, the Pogo LR 1A is ready to test fly. I'm a bit anxious to fly it as I've never flown a plane capable of the speeds this thing is able to reach. Still I'm excited as well as this is what I've always dreamed of flying, fast pylon planes

The plane was built up to EF-1 Racing specifications, although I don't really intend to race, I just wanted to burn fast holes into the sky, and have an adrenaline rush while at it. I've been told this plane will provide it in spades at around ~120 MPH

  • E-Flite Power 25 - 1250 kV Motor
  • E-Flite 60A ESC
  • Spekturm AR 6210 Rx with Satellite Rx
  • Spektrum SH5000 Servos
  • Turnigy Nanotech 4s 2650mah 30c LiPo
  • APC 8x8e Propeller

I have bolted on a APC 8x6e prop for the initial flights to keep the speed down. I can also run a 3s pack to make it more tame, however I have also ordered a few Nanotech 4s -4000mah 30c packs to get more run time for general sport flying. I have also set up the recommended Dual Rates and Expo as the machine does not require the full amount of control surface throws. With exception of the rudder, only Expo for that..

I was able to maiden the F-15, but it did not go well.... It is severely under powered and barely got flying. I ended up crash landing it as I could not avoid the trees that it veered off into as I was trying to keep it aloft. It's fixable, but in need of a motor upgrade. If I would have catapult launched it, it may have been OK.

The retracts are really fast and abrupt, but I was surprised the unit rolled for take off on our grass field as well as it did....

So at this point I'm repairing it and will increase the motor and ESC. I do want this to be a good flying model for me, so will try to make a silk purse out of a sows ear....

The forecast today was thunder showers and winds +20 Km H... However that did not deter me from maiden flight'ing Marie, the HK 1.2M P-51 Mustang.

I waited for a break int he weather, and headed out to the flying field. The wind was pretty gusty, and Environment Canada stated it was 20 km h. The flags at the club and the wind sock were pretty stiff, but then if you live in Saskatchewan, you have to learn to fly in wind.

I put Marie on the runway. She would not roll on the grass, as she nosed twice, before I decided to just hand launch her. This worked well, and I was underway. She needed some trimming, but after that was done I settled in with her. With the wind she was smooth, and predictable. Against the wind she was a bit under powered. I think a motor or a battery upgrade may be in order. Another fellow on the forums has the same plane and he upped the battery pack to a 4s pack from the standard 3s, which increased the performance to a good level I'm told.

After flying around for about 5 minutes, I put the gear down to bring her in for a landing. The gear is very slow moving as it is a worm gear driven affair. I was able to bring her down easily, and smoothly. However she did nose in soon after touchdown. I will probably look at upgrading the landing gear as I can't seem to keep the wheels in line, the assemblies twist on contact.

Overall she is a pleasure to fly and looks very good in the air. The color scheme really looks great in the air,...Continue Reading

Wow, this is one gorgeous plane!! I'm still in awe at what can be had for the price I was so excited to open this one, and I was not disappointed!

I love the look and size of this airplane. I was really wanting a general fly around sport plane, and I'm hoping I can stick to the plane, and not go too over the top in components with it. Power will be electrical, and I have ordered a Castle Creations Phoenix Ice 100A ESC for it. Motor is TBD, as I work out what i want to do with it and the logical sets of batteries I will need.

I do want speed, however I also want flight time, and basic Hi Performance fun

I have had my eye on this airplane since getting into the hobby, I can't believe it's actually going to happen! "I need NOS!"

So seeing as I just finished Marie, I had to jump into the next project. The Starmax F-15. Let me start by saying this kit really excites me! Must be due to the fact that I love F-15's

The kit itself is pretty impressive for the price. It's nicely packaged and finished. I would say I was pleasantly surprised with it. It looks wicked in the Dessert Camo paint scheme.

One thing I'm concerned about is the attachment of the wings... They have a small tab that is glued onto the fuse and that is it I suppose there is not a lot of pressure on these wings and it depends more on RPM and thrust to fly.

I spent most of the evening carving the cockpit and getting the pilots mounted. I printed some instrument panels up and made some ghetto HUDs I heated the co-pilots neck with a heat gun and twisted it to the left, just so they would not look like identical twins in the pit
