A must if into gliders better than flaps or use in conjunction with flaps cheaper to buy individually rather than a pair

I ordered a left & a right e-spoiler. The right one works as advertised. The left one was all sorts of screwed up, glitchy & obviously defective. Let's talk about the one that did work though. I noticed the HK e-spoiler only requires a very small range of stick movement to go from 0 to 100pcnt deployed. This means you don't get much resolution. Unlike other e-spoilers these are setup so you can't bottom-out the endpoints & fry the motor. They just stop once they reach either end of the travel. That's actually pretty nice. There is a LOT of slop in the mechanical linkages between the motor & the blade once it's deployed. That is not so good. Thankfully theyre pretty solid when retracted so I expect the blade wouldnt tend to get sucked up when in flight. I think these would work great for a budget foamy sailplane but I wouldnt recommend you install these in a $1000 composite ship.
