RE: Delta Vortex build
In order to fit the nose gear retract I moved the tank to just behind the the motorbox. The throttle and rudder servo's I moved back to what the plans call out as the radio compartment. Moving the servos back to this location also helps out with the CG. This also places the fuel tank closer to the CG. I normaly use a bladder style tank from Jett Engineering to help with the distance, but I thought I would try the IronBay regulator.
I finished the bottom sheeting today and am filling and sanding. Hopeing to have the bottom covered by tomorrow night.
