DragonHeart, what struts, if any, are u using with the Irvine retracts. Were they easy enough to fit in the Spit? Can you post any pics of them fitted ? Can you recommend a servo for these or will any retract servo do?
Hi
Im not using any struts with the irvine retracts as the grass i fly off is a bit bumpy, as for the servo i use a Supertec Low Profile Retract Servo which is about £23.00 which is ideal for the job

i have these retracts on my Spit and my Zero and as you said for £20 if they bugger up its much cheaper to just replace them than fit air retracts, but soo far mine have been fine
Good Luck
