I have the Spitfire. The assembly was kinda tough at a few areas. Other parts of the build were just fine.
One thing that crossed my eyeballs was the wing. There wasn't a string installed along the root like most ARFs of that size.
Fishing the servo wires was an adventure in self control . Kinda like playing the kids game "OPERATION".
The retracks weren't too bad to install. I've seen worse. The Spit is a long tailed aircraft so one pound of weight was needed in the front. Flys great !! But which ever one you end up buying,,,, if it has retracks,,,,,don't go cheap on the gear. I wish I had spent the bigger bucks on my retracks. The plane weighs 11lbs. Also don't spare the fuelproofing around the engine and cowling.

Tip on fishing servo wires I stumbled onto......... (Elec fence wire) it's soft and bends easy yet it will follow the formers and spar and can be fished out without breaking stuff.
