electrics
Hey Don,
Given the different weather conditions for the week. How do you feel you stacked up with the electrics. Congrats on the finish.

RE: electrics
Greg,
Neutral. I was concerned about the smoke trail on the power plane but I actually think it made the plane look smoother this last week. I did not perceive any negative. Likewise, the electrics (QQ's, Chip's, Jason's, and Dave L's were the ones I observed the most) did not have any power issue in the wind. Their planes performed well.
I really like the 170 throttle feel, especially around idle to 1/3 throttle. It's really smooth and responsive, but not torque-y like the 1.4 and 1.6. It is a low compression piston.
I ran the engine at 60% throttle ATV limited on 30% nitro. Sean ran close to full throttle ATV but used a carb restrictor with 20% nitro. I found that although the noise db was the primary factor for dialing down the ATV, I was flying out too far and making too large of maneuvers given the power that was available. Maybe a 5 blade prop is the answer.
Since it appears that the Japanese and French will continue to use YS at the Worlds next year, it's a motivation for several US F3A top-level competitors to move back into glow. Right now my plan is to stay with YS.
Another item of interest that I saw something that I thought not possible- two electric "dead sticks" last week. One was battery and one was a motor issue during flights. I think these were more learning curve items (all but 5 of the F3A pilots were running electric).
