Hi, If you look at the other postings about micro nuts as we call them here, you see a remote bungee system I use that allows me to launch using my gear switch on the TX and the launcher is flawless. The jet was clocked using two different radar guns both with high 200's mph limits which we've used on the turbines I fly. Actually my speeds are NOT the highest the Micro's are capabale of reaching as I've seen faster myself! The key is a fresh lipo pack and maintaing the motor, Lube etc..I even put spars in it because of the flexing. I just watch a newbie get close to 100 using a STOCK motor,25 ESC, 4.75 4.75 prop and a 2100 lipo..of course the motor lasted about 2 flights! I think the weight helped him a bit. so these things scream but you have to go through a few first! We need a micro fly in!
