Oh, and by the way, went up for two hours today and can confirm that the CAS sensor polarity issue was the source of my problems.

Tracy C. - 1850 (RV-4) + 56 (RV-8) 1906 hrs total
David L. -
Dennis H. - 275 hrs - RV-7A Renesis
Bill B - 23 hrs - Lancair Legacy FG Renesis
So, how many hours do you have on your rotary now? Tracy, what's your total rotary flight hours? Just yesterday, someone was trying to label me as the "Rotary Guru" because I have almost 200 hours now. I quickly informed them that there are many others that are way ahead of me. Its been a while since we last tallied the total flight hours. So, if everyone flying wants to reply, I'll tally up the new total.
You know, Mark, there are some things you just can't give away - because nobody else wants them for some strange reason {:>)

Ed,
There's little chance of anyone else catching up to you anyway. You're the HCH champ!
Mark
Ok, Mark, but that detracts 2 points from your "Hairy Chested Hero" credit {:>)

Gee, two rotors to come home on doesn't provide much excitement,
That's the whole point of going with a 3-rotor, that and MORE POWER!!! BWAAAAAHHHHH
Gee, two rotors to come home on doesn't provide much excitement, Tracy.
Sort of reminds me way back in the old days of using the Rx-7 ignition coils and ballast resistors blowing on them. For some reason seems like that only happened to you and me.
We are all awaiting some performance numbers for that RV8-3R, so next time take your bottle and give those Ls1 coils a real try out.

Was finally getting around to doing hot weather cooling and altitude performance testing in the RV-8 yesterday. Cooling was good during a high power climb to 14500 ft where I leveled out ( I had forgotten to put the Ox bottle in the plane). Throttled up to WOT to see where the speed topped out at but. After less than a minute I felt some engine roughness and noticed rotor 3 EGT went above alarm threshold so I throttled back to low power. #3 EGT then went low off scale and I could tell that the engine was only running on 2 rotors. I then smelled a faint electrical burning smell that lasted about 2 minutes. Engine was surprisingly smooth for having a dead rotor and still had more than enough power for cruise flight but obviously it was time to get back on the ground and find out what went wrong. did all the usual diagnostics on the long glide down with no joy.
Made normal landing, poped off the cowl and coil diagnostics test revealed that both coils on rotor 3 were dead. I had done the coil disable tests prior to takeoff so I know they were both good then. I'm using RX-8 coils and there have been too many failures for me to feel good about them any longer. I ordered a set of LS-1s to replace them.
