Thanks to all... I see - only buy one and fly isn´t possible! But thats the reason why it´s so fascinating!

To Tony:
I have the sport-jet version - the smaller one. Maybe when it ran good, I will buy the stronger one - the quality is fantastic!
Mr. Bailey gave me three sizes 0.56/.057/.058 and wrote that these sizes are optimal for Methano/Nitromethan. He helped me a lot.

With all your help, it will be a interesting weekend!

Thanks
Richi
