Well, I am pretty new to this hobby but i learn pretty fast. I have had a couple motors and have had problems with them. Recieved tons of help and input as to how to make one in particular work well. An Evolution .46. I can get it to run great on the ground. Hold in air shake crazily in all angles and runs good. put it in the air and dead stick. Same with another motor. I was pretty dissapointed in the Evolution motor but i am realizing that it's probably not the engines fault just my lack of knowledge. I can get it tuned and very pleased with ground performance but I believe my fuel tanks are to blame? The models in question are the Hangar-9 P-51 PTS and the Nexstar ARF. More noticable in the nexstar than the P-51. I Crashed the P-51 and am in the process of rebuilding it so I descided to use the fuel tank to test run a new JBA motor I purchased. After pulling it out i realized that the tank is in need of a new seal or something. I fill it with gas and it only gets about half full and when I remove the fuel pump line. Wow lots of pressure and it all blows back out or pushes out the muffler. Is this because the vent is stuck? Probably due to my crash in the trees or sitting around dry? So I pulled the tank out of the nexstar and realized that it was very very loose in its fixed position. So my question is, could the tanks be vibrating, causing an irregular flow which results in deadsticks? I see clearly how to fix this issue on the P-51 as it is very easy to get to. Now on the Nexstar I have a good idea of how i would like to put in an extra bracket and foam to tighten down the tank but if someone had a pict or idea of a fix for this I would greatly appreciate. Also can someone point me into the direction "Thread" about converting Nexstar to a tail dragger.

I in advance, Thank you for your help.
