Hey guys...I've got no experience with the bigger planes from Ace/TT, but I do have a Seamaster ARF. This is (by far) the best quality ARF I've seen. Excellent covering job (ultracote), beefy hardware, and good build quality. I also have 2 TT Profiles, a G-202 and Extra 300...these are pretty much the same plane.
The quality here is, ummm, less. The covering is that sticky backed film. Do they fly well? You bet. I crashed one very badly, disintegrating the wing...that night I CA'd it back together from pieces in a sack, covered it with Towercote and flew it the next weekend. Another TT arf I've had a couple of is the TT Champion 45S, on floats, which is pictured below. Nice flying airplane. I have crashed 2 of them and the fuselage breaks right behind the canopy. Wing is tough, but the tail assy is very long and should be beefier. I still have one and it is an excellent flyer. My fave knockaround TT ARF is the Lazy 51. I have flown it this winter on skis... what a blast. The quality of this ARF is much like that of the Seamaster. Ultracote covered, ply sides, all wood construction. Nice.
On my ARF quality scale, I give the Seamaster and Lazy 51 an "A".
The TT Profiles get a "B-, C+" mostly because once the covering is punctured, you pretty much have to strip it and recover the whole plane...it doesn't repair well.
The Champion flies very well, but has the crap-o stick on covering, and has a flimsy tail assembly. The wing is very good. In fact, I am currently in the middle of kit bashing a twin C45S...that will give me somewhere to put the two gp-42's that are taking up shelf space.
I think they are all good value for the $$$, considering you can buy a 45S ARF with Pro-46 and 4 servos installed for around $170.
(not from me! I do not sell anything!)
Email me if you have more ?'s.
