That 2oz should get you decent flight time with that .10. Have you tried a WOT test of it to see how long it'd take to drain the tank?

A few things I noted when I maidened my smaller bipe when compared to my larger .40 size planes is that it got knocked around more by gusts and that four ailerons on a bipe can roll it pretty quickly. Plane was also much more sensitive to small bumps in our runway during take-off and landing.

Good luck on the maiden!
