RE: Another Conversion
A few obvious errors, the thrust numbers are not right, he uses the ThrustHp chart..NO WAY...
The ignition is not the same as Dessert ? Aircraft uses, it's a Chinese look alike...Nothing wrong with it, just not accurate...Almost everyone is now using that Chinese ignition, rebranded ...

RE: Another Conversion
RCIGN1: I agree with you on the data. I noticed the mix was 16-1... that would put a lot of oil in there for the rod bearing...ect. But more oil more power. I have a Thunder Tiger pro .46 and it is one powerfull engine. Gave it to my Grandson and he loves it. I never ran the bigger 1.20 Thunder Tiger, but I suppose it may be about the same quality as the China made Super Tiger. Best Regards Capt,n

HUummm. I had a like new Supertiger .90 gave to me. It has a broken off exhaust bolt. It seems like making a new gas head for it may be fun!! Capt,n

RE: Another Conversion
There are typically several big glow engines (Super Tiger or other) in the classified ads at any given time. A lot of people shy away from these due to the glow fuel consumption rate (real or imagined) and carb / pump problems (real or imagined). Either way this creates an opportunity for the conversion crowd to pursue another line of conversion (from glow to gas / glow) relatively cheaply. Just one opinion...

RE: Another Conversion
I believe the stock glow carb on a Supertiger .90 should be ok for at least a good test. You can aways make an adapter for a small pump carb. Capt,n

RE: Another Conversion
Ken,
I'm looking at a ST2300 in the classified as well. That modified head on the Thundertiger 1.20 really grabbed my interest.
I've got a ST3000, an ST2500, and an ST3250 laying around that I've avoided using on my projects until now. The Walbro carb on gas / glow ignition solves the fuel problem without adding an EI.
I'm looking forward to trying the throttle arms.
Sent you a PM as well.
Thanks

RE: Another Conversion
Check this website for Super Tiger gas conversions:
http://www.aero-sports.com/airhobbies/services.html
However, a good while back I e-mailed them twice about the conversions, with questions about how they were handling the fact that the crank pin wasn't hard enough to work with roller bearings. They never e-mailed me back.
Keith at BME engines is selling a converted Super Tiger .90, (That's where I got mine.) He doesn't convert customer engines however, and I'm not sure if he is going to offer more than just the .90....
Keith?

RE: Another Conversion
I think that gas/gow fuel with 6-8% oil content should work great with these big bore engines, also maybe the stock carb will be easyer to fine tune because of the methanol content, this is just a guess.
Maybe is time to experiment again I have a Magnum 1.8 that is begging to be converted to gas/glow
