good luck with the conversion
air prop riggers can be REAL quick as some of the people on RCAW have found out! all be it nitro powered but up in the 50mph range!
i did try a quick depron style one but made a measuring mistake- battery would'nt fit in properly DOH!! so couldnt water tight it!! lol
i think i'll have another go at some point
im gonna stick at my rigger though- finally got it up on plane -i had the strut far to shallow and also i fitted some rear sponsens to get the back up quicker
modded the battery cover to take my bigger lipo and ready to go and try it out!
have you got any pics of b4 you mod it to air prop? and then after??
