RE: Make your 2$ Landing Gear
That is interesting. Post some video of it in flight if you can. The only thing that concerns me with that setup is where it is attached. If there is a significant sideward impact force to one of those arms, there is a high possibility of shearing off the plastic thread shafts where the battery tray attaches. I have done that by overtightening a nut. The thread shaft just came off inside the nut. Unfortunately, a whole bunch of stuff has to to come off just to replace a strut. If it's just for learning to hover a few feet off the ground, it shouldn't ever be a problem.
