The horizontal stabilizer is fully-sheeted; lots of those not-so-obvious wrinkles lurking there. Take your time.
My elevator had a slight twist; IOW, the trailing edges did not line up. Uncorrected, this will cause all sorts of grief when trimming the plane out (basically, you won't be able to). Its no drama on a model with split elevators and one servo per side; just tweak the linkage and nudge the sub-trim if you must. On a model with a one-piece elevator like this one, utilizing one servo...
Fortunately, it is easy to correct if you are CAREFUL. Figure out which way (and what side) you need to twist to straighten it, support the side you aren't twisting, apply TWICE as much twist as you think it needs, and apply heat to the opposite (supported) side while maintaining the twist. Remove the heat, maintain the twist until the covering cools, then check it. Might take you two or three attempts, but trust me, its worth the effort.
This one has a wood joiner, and is actually a LOT easier to correct than one with a wire joiner. I've had to do this on some bottom-tier ARFs that used a wire joiner, and it was a significant rectal discomfort to accomplish without trashing the balsa elevator. This one was, relatively speaking, a piece of cake.
Okay, break time. Yeah, the twisted elevator and bowed aileron were a couple of 'Aw, crap!' moments, but easily fixed with a bit of patience.
Maybe that's why they call it modeling...
I'm going to say something here, at the risk of annoying some folks. I'm new to this electric gig, and it seems that quite a few e-guys are into the foamie planes, be they a profile 3D job or "scale" warbird, etc. I have done three foamies since beginning e-power (scale warbird, a profile 3D'er, and a motor glider) and I have been tremendously underwhelmed with all three. There simply is NO precision there.
Okay, maybe I was expecting too much. Or perhaps it is unfamiliarity with the material. But my first e-plane was an H9 Pulse 25, and it is an excellent balsa sport model. It flies just as I would expect it to; i.e., good. This AeroWorks Extra is a cut (or two) above that one, in terms of build quality and overall kit quality. What a relief it is to deal with, after those miserable foam things.
Okay, done with all of that. Flay me if you will... I don't care!
I'll be back here when I have something to "report"...
