Just a quick update… I received the piston ring yesterday in the mail. After a few choirs, it was down to the hobby workshop and started in on the YS. I removed the motor from the Rave and stripped the YS down to its case. The sleeve has some marks / scratches that is only visible, I’ll microscope (30x eye loop) the sleeve to verify this.

The piston isn’t pretty, half of the top section, above the ring, is shattered. I believe it was from switching from rich / lean / rich condition....

Yesterday was our club meeting, so it was a good time to try out the Rave loops on my Trex 700. The meeting was ok, had the usual info, and I received a CD from our secretary with photos from our heli fun fly! Will post them later.

I put up 2 flights on my 700 with great results! The motor is breaking in fine, and the loops work. I just need to add a small piece of wire tie (like the instruction state) to each that will help in tightening them down more. So hopefully this will end...

Saturday was the last day of 100+ degrees!!! Not sure how long this will last, but I'm enjoying it. I decided to get out early Saturday before the temps got too high, I really wanted to test both 90 size machines!

First up was the Rave. I had everything ready to start and the motor didn't want to turn over. I pulled the plug thinking I had a hydraulic lock, and it still won't turn over. So I removed the fan shroud, then pulled the backplate first before the head. The inside was clean...

These last 4 days have got to be unreal…100+ degrees!? How much longer will this last? I’ve been talking to the other two guys that are coming with me to IRCHA this year, and we decided if the temps are in the upper 90’s or 100’s…we are not going. There is no sense in enduring that kind of heat and risking our health. So with that said…what is winter going to be like?

Anyhow…I started looking at my heli’s after the fun fly to see if I could address some of the issues I am still having....
