RE: 71" GSP Spitfire in need of conversion
I'll get that article and copy it tomorrow and get it in the mail -
By the way - go look in the "marketplace" section - there is a SuperTiger 2300 for about $139.00. There appears to be two good ways to go on the ignition. RCIGN1 sells his ignition system for (I think) about $35.00 + you'll need the proper coil from CH - about $21.00 - so for about another $50 you can convert it to gas - or you can buy the CH ignition kit for $89.00 plus the magnet - so let's say for $100 you can get the CH system which retards and advances the timing. So for around $250 (round numbers) you can get a gas engine in this airplane that ought to have plenty of thrust and not weigh too much. At the cost differential in fuel, it doesn't take long to justify the conversion.
Maybe some other guys will comment on this approach - but I think that's not too bad a deal. By the way, CH sometimes has used ignition sytems - apparently some people upgrade their systems, and trade in a good ignition. I bought one and he guarenteed it for 90 days - it's going on an 45cc Stihl (when I can get to it).
