FT-3D Speed Build
Hey everyone! I know this is the FT-3D scratch build thread, but I just put together a speed build and thought I'd share my experience here. I used to build blue fan-fold-foam planes but have been out of the hobby for a few years. Here's a
link to my old RCGroups blog if you want to see some of my old blue foam builds.
I'm not a 3D RC pilot so I chose the FT-3D for aerobatics and because it reminded me of my old blue Piranha build. I really like the speed build kit but I had some trouble getting clean cuts in the water-resistant foam. I started another thread here asking how to better work with it and it boiled down to dull blades and user error.
I used the recommended Powerpack C and the build took two evenings. My biggest head-scratching moment was trying to figure out the proper motor mounting setup with all the provided mount options. The most difficult thing to do was bend the wire for the landing gear. The wire that came in the kit (~1/8" dia) is stout and doesn't bend easily with pliers and hands. I had to rig up a vise with some scrap metal and clamps I had laying around.
I took her out for the maiden last night and it was a real success! I was cruising around against 5-10mph winds on 1/2 throttle with little trouble and the 10x4.7 prop made it really easy to pull out of any stalls. With just a little trimming, I was looping and rolling in no time. And the high rates...good Lord...I'm going to have to dial the ailerons down even more to tame that crazy roll rate.
Inverted flight required a lot of elevator but I think that's because my CG was a little too far forward. I didn't even attempt a knife-edge. I'm using some long-ish 3s1600mAh that wouldn't go back far enough on the bottom of the powerpod due to interference from the internal wing spar. Has anyone else run across this problem?
I know the plain brown plane doesn't look as good as some of the amazing paint jobs I've seen on this thread, but here are a couple of pics anyway. (I think it's funny how it matches my workbench top.)
I really like this plane. I think it is going to work wonderfully for aerobatics and will be there for me when I'm ready to start learning 3D. While the speed build kit makes the build easy, I would not recommend this for beginner RC pilots. It can be tamed down with rates & expos, but I would still recommend this for intermediate RC pilots who are ready to step up to a more aerobatic plane.
