Thanks all for the advice! I guess I'm leaning towards a GP 42 due to it being light and the price being right for an engine that will probably take some abuse. The other option is a .25 but it's not a whole lot lighter and really lacks in horsepower. A .32 for around 60 would be an option for me. I have an OS .15 with under 2 hours on it but it's to small for much of anything. I've got a radio now! My dad gave me back a 4 channel Airtronics with low hours, but it's probably from 1997, that I used to have. Thinking of getting a new battery pack but he says it still works fine. Feel free to add more comments!
