I would agree, Ed; in principle.

But its kind of difficult to spend $50+ for a spinner for a $200 ARF. Tru-Turn has gotten mighty proud of their stuff. I know it is top-shelf, but...

Lord knows I'm no cheapskate when it comes to my hobby. But you gotta draw the line somewhere. I plan to get a Tru-Turn for the Sig SkyBolt that's next up on the board. But I would no more put one on the CG Matrix I'm repairing now (after the aileron horns pulled through the wood and almost fluttered it to death) than I would on a trainer or Stik.
