Just weighed my new Accel Katana 40 at 4 lbs 8 oz with 46FX, Zinger 12x4 modified wood prop, Dubro spinnernut, Graphtech CF gear (heavier & stronger than stock aluminum struts), 4 cell NiMH pack, Tower muffler (10 g heavier than stock OS). This replaces one I flew last month, on which I crushed the fuselage while trying to bend back the aluminum struts after a deadstick landing. (I should learn to tune my engine better.) The new job has the CF gear located 1-1/2" forward of the stock location, as I kept nosing over on grass field with the original. I was OK as long as I held full up elevator while maneuvering on the ground, but everytime I would forget, the nose went over. Bigger wheels too, of course. Now I have 5/8" dia birch dowels for the landing gear bolts. These dowels are not going to crush. Had to strip the fuselage to do this, re-covered with monokote Insignia Blue, close to the Ultracote blue on the stock covering. I also put Dubro ball links on everything, since the supplied linkage hardware was a bit on the sloppy side.

Despite my minor complaints, the first Katana was an absolute blast to fly, and I expect even better results with my little modifications. I did move my CG forward a bit from the first version, now have it 138 mm back from wing LE at root. I had it about 1/2" further back before, which was good with a full tank but slightly tailheavy below 1/2 tank. Now I'll be slightly noseheavy at takeoff but nice flat glide if I have any more deadsticks. (Which I know I will, because I fly the tank dry lots of times.)

This gets my vote for the most fun you can have with a 46FX and $125.
