be carefull using car fuels in planes, plane engines need around 0-10% Nitro, 18-20% oil and i used to run my HP Savage on 25% Nitro with 12% Oil

i didnt really need a sim, just get yourself a kit to build and try some new things with your heli (fit a few little lamps to it and take it flying in a dark room , something i loved to do with my Picooz)
