Missed a shot of the JetTronic brake valve position. Like Bill I'm trying to get as much forward as possible to help with the balance, for ref I have heavy duty velcro on the back of the tanks (which are flat) and on the bulkhead. This retains the tanks along with the UP3 valve plate and MAP mounting base. All three Li-Po pack go in the nose 2 x 4200 and 1x 5200 2s all from Graupner.
