RE: OS FS-52 to RCEXL Spark Ignition

Yes, the CH boots are fine. I have a couple CH ignitions too. If you didn't catch it in the thread I made my own boot for this one, and that's what failed.

RE: OS FS-52 to RCEXL Spark Ignition

I flew my FS-52 for the first time in a few months. I ended up with 3 failed spark boots this year. The first one ran for a long time, maybe 3-4 hours or more. The second and third lasted just a few...

RE: OS FS-52 to RCEXL Spark Ignition

My FS-52 starts very easily. In my video on my website it starts on the first flip. I got lucky that time, but it's usually only a few flips. My Enya 46-4C also started very easily. If it doesn't...

RE: OS FS-52 to RCEXL Spark Ignition

That pigtail should the the outer braid on the high tension wire lead. This should be grounded to the engine case.

RE: OS FS-52 to RCEXL Spark Ignition

Unfortunately, I did not take photos while building it. I have another to make soon, but I need to get another McDaniel head lock.

I just want to clarify that the CH boot is just like the one I...

RE: OS FS-52 to RCEXL Spark Ignition

CH Ignitions offers this type of spark boot. They don't list it on their website. I called and inquired about it. They cost 13USD. I had the parts and I like making things, so that's what I did.

RE: OS FS-52 to RCEXL Spark Ignition

Correct. However the lubrication situation in four strokes is very different than two strokes. A four stroke collects a certain amount of oil in the crankcase, then, the excess is pushed out the...

RE: OS FS-52 to RCEXL Spark Ignition

I think 5% of Aerosave will be perfect. I think with a high quality lube like Aerosave, Aerosynth, or Motul Micro, even less would be acceptable.

I'm currently running stock compression ratio. I...

RE: OS FS-52 to RCEXL Spark Ignition

I have not tried gasoline yet. I did run E85 in the Enya. You definitely want to use compatible fuel lines. Even the 15% gasoline in E85 caused the silicone to swell and not hold onto fittings. I...

RE: OS FS-52 to RCEXL Spark Ignition

I had a chance to run the engine today. It started up nicely and runs fine. The needles are sensitive on 0% nitro fuel. Idle transition is not great. I can't richen it enough slam the throttle open...

RE: OS FS-52 to RCEXL Spark Igntion

Thanks for the comments guys. It too expect it to run just fine. It's going to rain all weekend in Chicagoland, so I probably won't run it until Monday.

I have an Enya 46-4C that runs well with...

RE: OS FS-52 to RCEXL Spark Igntion

I guess Maynard Hill used Coleman fuel for his duration flights. He worked with the FS-61 for all his attempts as it was the largest he could use to obtain an FAI record with the 10cc limit.

RE: OS FS-52 to RCEXL Spark Igntion

Oh yes, I forgot to mention that I also replaced the main bearing with an open type and the front bearing with a rubber sealed type. The crankcase vent is plugged, just visible behind the ignition...

OS FS-52 to RCEXL Spark Ignition

This is how my spark ignition conversion turned out. In addition to the ignition, I made internal oil passages like the OS Alpha series use to recirculate crankcase oil to the intake. I hope to run...
