I 3d printed the mounts and stuck a paper clip through each one. Stabbed it into the aileron and hot glued it. Here's the link to the files:How did you mount the ailerons?
If anything I’d lengthen the wingspan a couple inches. All the other ideas sound good though.It's been a little while, I took it up again. I flew it on a Master Airscrew 3-blade 9x5 prop and I love the prop. Super quiet and very robust. The plane flies OK but it has some aileron authority issues for sure. I ended up using a lot of rudder even when I cranked full aileron just to get it to turn.The flight ended when a gust of wind pushed the nose down about 40ft from the ground and I couldn't get it back up. Nosed right into the ground. Broke the firewall but the prop was OK. Good job Master Airscrew! I've got a few ideas for changes to make on version 2:
- Shorten the wingspan a couple inches
- Make the ailerons a bit fatter
- Enlarge all the tail surfaces
- Lengthen the aft section of the fuselage a couple inches
If anyone can think of anything that might improve the roll and pitch control please let me know!!!
Why is that? I thought shortening it would increase roll rate.If anything I’d lengthen the wingspan a couple inches. All the other ideas sound good though.
It will make them more responsive, but from your video it looks like it’s already a little unstable and decreasing the WS would exaggerate that. If I were you I’d increase the size of the ailerons, add a little undercamber to the wingtips, and enlarge/extend the tail. Just FYI the ailerons on my ft freedom fox don’t have very much authority compared to lots of my other planes.Why is that? I thought shortening it would increase roll rate.
Haha I forgot to add a picture of the new wing I have! I don't think I have a video of it flying either, that's my mistake! My new wing has under cambered wingtips with less a less extreme airfoil overall. It's a lot more stable now, but lacks aileron authority. I'll put up pictures of the new wing, and see if I can find a video of it flying.It will make them more responsive, but from your video it looks like it’s already a little unstable and decreasing the WS would exaggerate that.

Have you thought about extending the bottom skin further out towards the wing tips? This would strengthen the outer section of the wing from getting damaged. I look forward to seeing your progress.Well guys... Time to resurrect this thread, three years later. I've come to revisit the Kitfox! I've made a brand new version out of flite foam board. Here are some of the major changes:
- Less extreme airfoil shape
- Ailerons moved closer to the wing
- 30% enlarged tail surfaces
- Shortened nose
- Quick release struts
- Added a battery hatch... desperately needed it
- Cool looking three blade prop
Took it out for it's maiden flight a few days ago and it flew alright. It's a little squirrelly in the wind and I haven't quite figured out how to land it, it's a little finicky. But I was pretty happy and I've started putting a new paint job on it. I will update with photos later when the paint is done.
I forgot about that! I did decide to bring the bottom skin all the way to the wingtips, it's definitely much better than before.Have you thought about extending the bottom skin further out towards the wing tips?

🥵 dangggggSome better pictures of the complete KitFox. Unfortunately these are the biggest wheels at the local hobby store, but I ordered some new ones that are much better "bush" tires.
I'll update on flying it later today. Enjoy!
