Well I need to go to the LHS to get some 3/32 for the stab cores;mean while, I will leave the wing cores weighted for a couple more hours..

I like the first combo with a 91 FX greatly simplifies things as opposed to a tuned pipe buried in the fuselage as the design was intended....then again a long stroke swinging a 13x-- would be nice and the ship would have to trim out better as opposed to the side mounted exhaust on the O.S.91 FX I will have to search the RCU market if I decide on a tuned pipe running down a tunnel with in the fuselage and exiting to the rear of the canopy.
