GG,
Thanks for the info. The P-38 is the Raidentech 52". It's actually my bro-in-laws, but we're both going to school on this one as it's the first with retracts. My bro-in-law doesn't have access to a computer so I'm the link to these forums. Everyone has been very helpful! Thank you all. He has said a few times that maybe an air system would be the way to go. You mentioned some smaller systems. I'll check them out. Might eliminate a bunch of headaches. There's not a lot of room for all of these servos. Also, which do you think would weigh more, a small air system or the mechanical 3 servo system? The HS-75s are a bit porky. Thanks!
