RE: CMP Hellcat
I've been very satisified with mine. Been flying it quite a bit for the past couple of months. No unusual wear and tear, nothing coming loose. Didn't have to re-enforce the servo trays or bulkheads. I did add a bead of epoxy around the edge of the firewall on the inside, but that's something I do on all my ARFs. Mine is the same plane GiantScalePlanes.com sells.
I've seen another F6F on ebay that looks about the same except the pictures show different decals then came with mine. Mine are satin finish and the pictures I saw of the other plane appear to be glossy. Glossy decals and satin finish plane do not go well together. The other plane is pictured with a large white arrow decal on the tail. Arrows did not come with my kit.
I paid $127.50 not including shipping, which was another $35. GiantScalePlanes sells it for $199 before shipping. Was it worth it? Sure was. Go to a LHS and ask for a 120 sized fiberglass warbird with sheeted built up wings and tail, flaps, solarex painted finish and see if they can get you one for under $200. I think it unlikely in the extreme. Better yet buy a wood kit the same size, assemble it, cover it, paint it, buy the hardware and take a look at the tab...Under $200? No way. Not even going to consider the cost of labor to assemble such a nice plane.
As far as the fiberglass goes, if it holds up to flight and ground handling it's thick enough for me. I've put mine through some hard landings and extreme gyrations in flight and it's holding up just fine.
Just my $.02
