Hey A+++ for effort G! I've had plenty of failed attempts in my past! Looked like it needed more noise weight. My guess is the flight stabilization had negative effects?

I turned off the stabilization while I was correcting the roll, I thought that might be the cause of the roll. I think the problem is in the wing itself, too thick and possibly not giving balanced lift from side to side.
Right now I am trying to figure out if my HK G15 950KV motor will work in the GPM Electric Piper. They are calling for a brushed t600 with a 2.5:1 gearbox. I would rather use my brushless and go direct drive

While a cub is a viable trainer I would suggest a "typical" trainer which has a little dihedral in the wings and much more forgiving of stalls and has a tricycle gear set up

I am looking at a few trainers as well, the only problem is that a lot of the trainers are fuel and not electric, unless you buy an ARF/RTF foamy.

check out the Nexstar Mini - Balsa construction - it is an arf but being wood it is simple to repair. Anything can be made electric. Stopping by dads house tomorrow and will pick up a few of my old nitro planes. The ones where I remember the engines being tired will become electric (one I am most excited about is my Old HOB .25 size P51) Or if you really want to build (which I think is a good thing) check out the 40 size telemasters on Hobby Lobby. EXCELLENT planes - easy to build and fly very nicely. www.hobby-lobby.com/telemasters_216_ctg.htmWhile trainers are not pretty - they do what they are supposed to do - train you to fly

Looks very tail heavy. Many, many failed attempts myself. An irritating way to learn but a very GOOD way to learn. Great effort G! When I was learning to fly I was told " IF you're not crashing you are not learning." Still hate to crash but I learned well.

While a cub is a viable trainer I would suggest a "typical" trainer which has a little dihedral in the wings and much more forgiving of stalls and has a tricycle gear set up I downloaded the instruction manual for the J3 Electric Cub and it does have a "little" dihedral built in, but from reading the instructions it looks like it would be easy enough to add a little more. To put the stated amount in requires that you prop one wing up with their provided gauge and sand the wing roots till there is no gap. If I made the gauge a little taller all I would have to do is sand a bit more. Might have to add an extra piece of balsa to be able to sand what I want though. I am still up in the air about it, I want something it the size range of the GP Cub, 58" wing span and under 56oz, and will work with my electronics.

As I said, I had time to change my mind about what to get as a replacement for the scratch build and I did. I decided to get the Jet Legend T-45 Goshawk Kit www.greathobbies.com/productinfo/?prod_id=JLET45KJust kidding ;D I am leaning very hard towards the Flyzone Sensei EP trainer RxR version and put off building a balsa plane for a little bit yet. The Sensei comes in right around the same price as a build on the J3 Cub, but I can have it ready to fly in about the same time it takes to charge a battery. I have read a few reviews and watch a couple of Youtube reviews and they pretty much all say the same thing, this is a near to a perfect trainer as you can get. Come Thursday I could change my mind again though

Hard luck mate. Us bikers have a saying " its not about the destination but the journey". I'm sure you learned a hell of a lot along the way.

Thought of it for some reason after your quote ;D G, I am not telling you what to get but for me the T28 is near perfect even for someone like myself being a newbie to planks. If I can take off and land all on my own only after the 3rd time I flew it, I know you can too bro. All I am trying to say is that the T28 is very stable and fly-friendly for even someone like me

But the Sensei has bomb bay doors and the servo preinstalled I am going to step back from my warbird till I can successfully fly something a bit more docile. Once I get the hang of the trainer I will mount a keychain camera to it and get some aerial footage of the old canal and see if I can see the parts of the old town that were flooded back in 1958. There is not much of the old town left, mainly sediment covered roads, but you can see the odd building foundation outlines

So I picked up a Flyzone Sensei Rx-R this afternoon and put it together this evening. Still need to do all the setup of d/r expos and throws. I know that this model has some motor/ESC issues, but I am not too worried about because I have the G15 motor and 60 amp ESC from the scratch build so I am ready for it if I need it. I will say that a 58" wing span and 48" length makes for a large plane. Big enough that I have to store it without the wing on

Nice G, awaiting your maiden sir...

Not sure when I will get a chance to maiden it, we got an inch of wet snow over night, so all the wide open fields will be wet today when it finally melts off. It's calm out right now, but we have also been getting some high winds over the last few days here, high enough that the puddles had white caps and the geese were flying backwards For today I am just hoping that the wind stays down so I can get a couple of pictures of it after the snow melts off and I get the rest of the setup done.

I found a home for the electronics from this failed attempt to make a plane, I am making an airboat. I am making pretty good headway on it, got the bottom and sides glassed in yesterday. The motor tower has been done for a few weeks now, just need a finish coat of epoxy so I can get it nice and smooth, and this morning I did up the camera mount. I just bought a Polaroid XS80 action camera, and it is waterproof up to 20 meters, 30' for the guys in the USA . I was sitting there looking at it, trying to figure out the best way to mount it to the hull and It came to me Part of the packaging was a nice plastic tray with a built in tripod mount so I just cut an opening in my radio tray cover and stuck the packaging tray through it. I still have to epoxy it in, but the angle looks to be darn near perfect. Today I will be doing a bit of filling and sanding on the deck so I will epoxy it in while I am waiting for the fill to cure. Then its on to the glassing in the deck and some finish sanding over the next few days and a water/float test befor I mount the electronic in it
