I am in the process of building my Avistar ARF and have a question. In the assembly manual it shows three CA hinges for each aileron but the aileron and wing have four slots. Also after checking all the places that need CA hinges and counting the number I was given I only have enough to put three in each aileron. Are three CA hinges enough for one aileron? Thanks.

CA Hinges are cheap buy a some its a cheap why to gain piece of mind

Amen to that

Yeah I guess from post here and else where, sometimes you
get shorted a few ca hinges.. Don't leave them out!! Get you
some from your LHS or order online!! Also inform and "TELL"
hobbico to mail you your shorted hinges.. Don't just drop this,
But make them make this right on the ca hinges with the added
postage... Maybe they will insure its right the next time.. One
things for sure.... You don't say nothing... And you must know
"Nothing will change"...
