Hey Jack, Yeah mine had the manual.. They are suppost to have an updated
man. in the Profile OMP fourm here on RCU... I may have missed something,
But I did not see any difference between the two..
The straps were installed correctly with the thinner foam on the fuse side????
Maybe just a bad strap is all I can say?? Had no problems today with the
replacement straps and tank... But I did use velco instead of foam this time
with the straps.. My tank moved slightly from the prop wash. I guess it was
because of the backing on the foan I used.. Anyway it's still there after today

Yeah I think they are making a bit on it.... But if you look at the "name brand"
profiles their prices are the same.... HIGH... I always wanted an EF 540, about
the same price, but they have been out of them for over a year... I ordered this
one, then I see that E.F. has some in &$%#.... I hated to spend that much $$$$$
on a profile, but I like them to play around with and learn and they are a bit
stronger for those "bad low times" It does stay together a bit longer in the "opps
times". I only had one other profile a Kangle SU-31<?> I got NIB for $50 on ebay
But one too many tail touches with it I think It's fixable.. But it's twice that I
snapped the fuse in just about the same place...

The 51 would be better.. It really likes the YS63
