I dont think that FG-84 R3 is that slouchy, On the video they are turning a 23x12. Which is not bad, But I would rather have gas as it is easier to come by.
It won't out perform the FA450R3 on GI (as far as power) like people think & will lag behind when CDI is used on the 450.
And that's why Saito is converting so many glow engines to gas?
You have to give the public what it thinks it wants regardless of practcality.
Should Saito ignored the current gas engine market?
Heck no. People get it in their heads that they want something, they will buy it even if it is not a significant improvement. Might as well give the suckers what they want.
Should Saito have utillized more proven components in their ignition systems rather than trying to utilize ''proprietary'' components?
Very much so. Most of their single cylinder gas engines are flops & require converting to C&H CDI & ZAMA/Walbro carburators for dependable power. Saito is taking a serious hit in reputation as this unfolds.
Should Saito have redesigned their engines for gasoline fuel?
Yes, but other than increasing displacement & (I assume) lowering CR they have not. Still the same crankshafts & connecting rods on most FG engines. The part #s for the crankshafts differ in that the FG crank has a provision to lock in the prop hub. (another poorly designed part of their ignition systems) No provisions for increased operating tempertures or reduced oiling.
A Saito engine converted to CDI while retaining methanol fuel will make more power than a gasoline conterpart W/less smell. It will run cooler & most likely last much longer. Other than the somewhat reduced operating cost for gasoline, (not taking into account reduced engine life) the CDI methanol engine will have all of the advantages of the gasoline counterpart.
If you want a gas burning 4-stroke engine, buy one designed as such from the get-go.
All this, mind you, from a rabid Saito fan that has been running CDI W/methanol in my Saito engines since 1997.
