Just purchased a Ch Ignition conversion kit for larger Saito engines. I will be converting a Saito 1.80 Golden Knight to run on Gasoline. CH suggests the rpm will be lower but 500-1000 rpm so it will be interesting to see how this converted engine performs. I have solicited Ron Czikowsky to be sure we have 2 sets of eyes and hands performing the conversion. It does appear simple & the only real issue is getting the timing correct. Another interesting comment suggested by CH is converting a glow engine to CDI will result in a more reliable lower RPM, usually results a in a gain of a couple of hundred RPM at the top end,with a fuel economy increase of up to 25%.

Well Fred,
Now that you have had a chance to run the engine on a stand, give us a small report, please. :P

We have run the Engine and did run into a problem with the Exhaust Valve sticking. We think that is because, although new, the engine has been sitting for several years & I used the wrong oil in the gas mix. Ron Czikowsky took care of the problem and we ran another 550cc of 20/1 gas through it using Redline Oil this time, and it ran very well. When broken in we expect an idle of about 1500 rpm with a heavier prop and probably close to 8k top end with an 18 x 6 prop. Currently with a 17 x 6 light wood prop 20/1 mix with low test gas, idle about 2K top about 7.6K. Now, what to mount it it in, maybe a Giant Scale Planes Fiberglass Hellcat?
