RE: *** CLUB SUPER TIGRE ***
Yeah, but don't forget that's just the *nitro* component. You've got to add another 1/5th gallon of oil (that's about $12) and the methanol $3.70, which comes to a grand total of: $30.70 per gal.
Now my ST90s suck a lot of fuel so a gallon is probably only good for a day or two's flying -- that's quite expensive!
If we go the 5% nitro route we can save quite a bit -- because the cost of the nitro is lower and the fuel consumption of the engines drops quite a bit too.
