Combat training is going well. abut 10 flights on my battle axe. I'm having a problem with the OS .15LA sputtering during flight, and on the ground.
Starts fine runs fine then I can see bubbles coming out of the fuel tank heading towards the remote NV.
This is a new tank with new lines, I'm thinking it may be fuel foaming?
If you dont know the battle axe, the engine is bolted to two aluminum rails ( home depot product used to edge 1/4" ply. ) The fuel tank is sitting on foam padding and zip tied to the aluminum rails. This seems to transfer allot of vibration to the fuel??

The engine breaking down looks to be related to the air bubbles... How best to deal with it?

I have another 3 oz tank I'm going to try..


Thanks

Steve
