SrTelemaster, can I have your telephone number? If you dont mind then send it to me via PM.
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.
PM sent Jari. Call me when convenient.
Sorry, I'm just not that impressed W/the Saito gas burners. Unless they have used roller bearing on the master rod journal of the radials, or any rod journal of a single/twin & increased the colling fin area I just don't think that they will last as long as the glow fuel burners @ the oil ratios they recommend.
Oh. they will probably last through the 3 year warranty, but I just don't see all the addded heat, reduced oil ratio & increased combustion by-products not taking their toll.
A 450R3 running spark ignition burning 15% N/M should put out @ least 5.8+ HP & last a lot longer than the gas burner.
I'm finishing up a 12.66:1 CR HC180 built on an FA150 case. I expect to get well over 3HP on glow ignition (my 9.56:1 stocker made 2.9 HP) On EI W/the same 15% N/M fuel I should see about a 6% boost so somewhere in the neighborhood of 3.2-3.3 HP on EI W/glow fuel.
I have it in my head to buy a gallon of 30% Cool Power Heli fuel. W/spark ignition it should be able to be tuned for some big HP even if for only short bursts. I have a 25% Hanger 9 CAP 232 ARF already set up for an FA180 & I can see some short duration high HP bursts for extreme vertical performance, torque rolls, etc.
Having big HP on tap would be a lot of fun on something that light & nimble.
