Btw, what do you think about the new radial gasoline Saito? I think it was FG-84R3 (or 83) witg 83 or 84cc fill volume, 5,7hp and just over 3kg. The Youtube-video looked interesting. Not breathtaking but good anyway.
Ok, I found the YT [link=http://www.youtube.com/watch?v=lwCd76ZBtOE]SAITO FG84R3 GAS BURNER RADIAL VIDEO[/link]. I'm not all that impressed. It runs like what a 450R3 on EI/glow fuel would run W/slightly less HP. (than the 450R3 on EI W/glow fuel)
A 450R3 on EI with nitro/methanol should make nearly 6HP, the FG84R3 makes 5.7. A 13:1 CR ratio EI version FA84R3 running on 15% Glow fuel would make 7HP easy, be just as easy to start, run a LOT cooler/cleaner & most likely last a lot longer.
If Sailto had marketed the 450R3 W/EI for glow fuel use long ago they would have sold a LOT more of them IMO.
I do like the design concept of the [link=http://www.rcgroups.com/forums/showpost.php?p=21757207&postcount=2312]IGNITION SYSTEM[/link]. (but not the way they mount the hall sensor & trigger magnets) Adrian @ C&H was trying to explain a system like that to me a few months back but I could not grasp the design.
