Thanks for the help on the motor guys. I really like the motor... it has gobs of power and was really reliable for the two flights I have on it. I'll try adjusting the timing a little and tuning. Then I will just hope it smooths out more as it breaks in. I might send the piston in for a Frank Bowman ring but I have a hard time consigning myself to no slick for two weeks

Bivens, I have tried the RC exl ignition with my bec set to 4.8v and 5.4v. I noticed that it is always .1 to .2 lower than the software setting says it is. Anyway the stock ignition will run either way but the RC exl ignition won't. It sounds like the spark is happening inside the module instead of at the spark plug. I have taken the plug out and done just as you suggested and it does spark on the plug but not every time. It hits the plug probably 1/3 of the time but there is always the sound of a spark somewhere.

Just make sure you have some sort of remote ignition kill. You don't want to be the guy who gets stuck flying in a circle up high waiting for his plane to run out of fuel. Or worse have a throttle servo failure/problem with the plane on the ground and have it run away or hit someone. Nearly everyone at my field uses the Smart-fly optical kills, so that is what I went with and it has worked great so far.

On my 87" SHP is basically the same but 2 LiFe batteries into my Wolverine switch via Deans connectors - 3 JR connectors out to power my Rx and I use the Tech Aero IBEC for the engine kill and as it gets it's power from my 2 A123 packs no additional NiMh is used.

Got an M6 and threaded out the 71 Slick wing blind nut, but felt nothing in there. Actually I think the threads are a little too bored and that is causing the stripping of the bolts, so will be debonding and tapping out the blind nut and installing the new one tomorrow night after it shows up in my mailbox...

I just switched some blind nuts out of a big Vyper and used a prop adaptor from an Omega (I think it was an Omega) Either way it was a smaller prop adaptor and it threaded into the the blind nut perfectly and gave some more surface area to tap on getting the nut out.

I had my 89 in hover with DA60 about 15" up, I also have it set up with a high idle switch and I had it on high idle. The motor jus quite, who knows what happened. If the Smart Fly Optic kill fais, it cuts the igntion. Thinking of removing it but I sure like to be able to kill the plane from my TX. What to do! Some guys at the field that have a choke servo use it to kill the engine, not sure if that is a good idea or not.

I just don't think it's safe to not have any sort of fail-safe kill device on big gas plane. I personally would consider a choke servo less reliable (and more complex) than an optical kill or IBEC, since the servo has moving parts and linkage while the others are solid state electronics. The Smart-fly optical kills seem pretty reliable among those at my field (as compared to ignition modules or servos).
