I Finnaly got take take it to my parent's pond today. It runs good on 6 cells but I put a 1.65" pitch prop on it and It runs alot better. I think I'm going to order a Graupner 700, a couple 7 cells, and a couple more props for it. I'm sure I'll be putting it on a tunnel soon if I can make the 700 work in it. I have access to a machine shop, so making it work shouldn't be a problem. The only gripe I have is the fact that it doesn't have a very far radio range.
