I am currently in South Africa on home leave. I will be buying quite a lot of spares before going back to Angola. I have a small Emco Unimat 3 lathe with a milling attachment. I will be cutting 5mm solid mainshafts, drilling the two holes and cutting the flat spots to take with to Angola.
I also downloaded the e-book Setup Tips for 400 Size RC Helicopters form
www.rchelicopterfun.com
Really worthwhile book that gives a lot of tips as well as setup details to tame the Blade 400 for beginners.
