RE: new Arf Boomerang 14lb thrust
Dave
I think what Alan is saying sounds reasonable. If you put the Jetcat solenoids/ecu/pump/battery as far forward as possible and use a UAT which I think is 10ozs full I think you could get a DRY weight of 14lbs 4oz I think the model should be balanced with a full UAT as this (or a hopper tank as I use) should never be empty.
I have given the 44 a couple of runs in the Intro airframe just to check systems and I have 4oz of noseweight left for a 190mm CG position.
There is very little weight to move up front with a 44. It does look very small sitting in the model!
