RE: Fuel economy and flight time for Magnum 120??
Crash:
Don't know what to say. That is lot higher fuel rate than I see on Saitos here. As an example I get an easy 15 minutes with an FA-120 on a 12 ounce tank. And still have a good reserve.
Another possibility - I use 15% Omega, if you are using higher nitro the fuel rate will go up. I've never seen the need to go higher than 15%.
