They are good little motors but can only be mounted in front of a firewall, they fly the Eflite YAK-54 really well. For $20 you cant go wrong they are worth at least a science experiment.

I have to go bigger on the prop not enough watts, the 450 is making 119 watts and the little 400 is making 122. I am switching over to Deans plugs from JST, I might be bottlenecking a little bit. Got a new TP 1320 and am only pulling 10 amps. I never made it out to the LHS to pick up more props to play with, I have been working on my BME YAK as you know, its finally done and ready to fly.
