Default RE: Nitro models pusher Bobcat?

Well- Just finished mine.... *yeah, I'm a late bloomer i guess....*

I anticipated a bit tail heavy state cause I put a medium size air tank in the rear above the fuel tank, and I have also been told that they come out heavy in the tail even without all the boom servos....
C/G as it sits is 9 1/8" behind the LE of the wing @ the fuse..... Sheez! I put a 2000Mah 6 cell pack in the nose cone in front of the front bulkhead (in front of the one in front of the nose gear bulkhead) so it's time to put the batt near or even behind the servo tray...... 7lbs. 9oz.

I did some of the mods discussed in the thread,
-125mg in the horizontal tail
-increased AOA to + @ LE
-set up spoilerons
-adjusted height of the engine blocks to clear crankcase of OS .55AX with Jett pipe

Also, I chose to change the way the surfaces were hinged, to a Monokote hinge on a top pivot bevel, as well as omitting the rudders altogether.
I also chose to clean up the wings a bit by laying the aileron servos on their sides with the only protrusion being the outer portion of the servo arm. access to the servos are through hatches on the top of the wing, Another mod I did was to cut a hatch in the bottom of the fuse, below the wing "alignment holes" which were threaded, and installed 4mm bolts to join the wings. They are not glued on. This way if I need to break the airframe down for service, it's no problemo..... not to mention that I can get to the tank if I choose to.
Once I get the C/G adjusted to 10.3", I'll be ready for a Maiden on sunday! I am hoping to go just a pinch faster than a fellow club members bobcat with the mods I did to just clean up a couple draggy areas. I SWEAR I'm not a touch competitive! He He!
