Normally I just fill the tank and tune,but for this plane we also tested it at maybe half tank. Most of us at the field are very strict about holding the nose up at full throttle before the first flight of the day. My Sukhoi with this .61 EVO in it usually seems to be OK on the ground with its nose up,but in the air is when it gets iffy. I never really checked for air bubbles. I do notice however this is common on alot of planes I see people tuning etc. and they run great. Heck,thats how you can tell the fuel is flowing,lol. I actually havent been testing it too much lately as I've just gotten used to it and know when not to push it. This thread kinda got more into then I had expected. I just wanted to say how I didnt like my EVO. I'm kinda glad it did now though,because I'm starting to want to play with it more to figure it out,lol. This weekend when I go to the field I'm putting it through the ropes! I might even take the tank apart before hand just to put in new fuel line and double check things again,then see how she does. I also want to test and tune it with about 1/3 tank of fuel as opjose mentioned.

Tell you guys what though,if I test it and it dead-sticks me again and I finally crash it, I'm blaming it on you guys!!!!!!!!!!
