Thanks Ryan for the info. Very useful indeed. I haven't had a chance to make a start yet, been hecticly busy. I got as far as printing out the plan. I didn't end up scaling it. I'll keep the tips in mind when building.

Another question, I have a nitro wildthing that I built a couple of years ago, with ply and balsa. It's got a .15 nitro engine, which i can't seem to master the art of tuning. Any suggestions if I want to convert it to fast electric?
