RE: GP GEE BEE
Jeff,
Mine has the PIO tendency, yet it is a tad bit tail heavy... I think it is the design. My best landing was dead stick... a scary feeling! I just added robo struts and will fly it this weekend. I added a RAM on board ignition system too... hope this helps with the idle. I am hoping to idle slower than what I have it set to now to ease the landing issue. I think my prop is pushing too much air with too much speed to slow down enough to plant the tail... it wants to keep flying. I put a larger prop with less pitch too.
We'll see how it goes. I am hoping to add some video of the landings to my site once posted.
