It's been a while since anyone has posted here, so I thought I'd wish everyone a Happy New Year! Holidays were hectic, so not much got done in the way of RC. stuff. I was totally preoccupied with rebuilding my now 19.5lb scratch Steen Skybolt from Dario Brisghella plans. It has remaidened sucessfully. Now, am continuing work on an engine I previously and mysteriously referred to earlier in this thread. It's not glow-to-gas, but I imagine this diversion can be tolerated, especially since some of the challenges of mounting electronic ignitions are common. That is the Homelite XL12 Chainsaw 54cc chainsaw engine. Pictures attached. What plane is it for? I recently located an OLD Sig Sundancer biplane ARF and put some $$ down on it. It's a 18 lb plane, and I feel fortunate for having located this extinct bird. Next up-another Saito 150 gas conversion. The first one still runs well after 2 years, starts every time, and has plenty of power. One thing I do notice is there doesn't seem to be much static compression, but it still starts every time and runs fine. In fact, the compression is so low after sitting that it feels like the valve springs are broken. Yet it runs fine. Theories on that?? Speaking of power, has anyone done any experiments with dynos for these conversions? Seems like they have a bit less power than nitro, and it would be nice to measure the HP more accurately. Also, I've recently gotten into telemetry so I can measure in-flight head temperature. I think this is very important, as we're dealing with gasoline here. I am using a Spektrum DX8 with a TM1000 telemetry transmitter. Hasn't flown yet, but I'm setting it up as we speak. I've measure head temperature on the ground after a good WOT run, and measured temps ranging from 275 to 305 degs F. Using the wrong fuel, I've seen these engines overheat in the air. Probably from over-revving, but It will be nice to see what happens in flight.
