I installed a Hayes tank with strap tape, due to my installed engine is a YS-53 with pressue fuel system. I didn't like the looks of the supplied tank!

I have had no problems with interference of the rudder/elevator pushrods. I used Dave Brown rods, with supports in the tail. May also be that my horns are farther out as you say.

I am running a 4-stroke YS-53 in the Aresti, inverted, with no problems until recently I developed regulator problems. I used the supplied mount, but drilled/tapped instead of using the straps. I had to add weight to the tail, but suspect your TT46 will be lighter.

I became nervous about the horizontal stab issue when I read the earlier posts. Per the recommendation of the owner of a LHS, I used an exacto knife to slit the leading edge approximately 3/8" deep from the fuselage to near the stab tips on the bottom. I then inserted some 0.007" X 3/8" carbon fiber in the slot, and used thin CA to secure the carbon fiber. It added strenth/rigidity to the stab even better than I expected! If this were to be done before mounting the stab, you could run a single piece all the way across. I would guess that I have flown the Aresti 20 times since the addition of the carbon fiber. The post that I read, had the stab failure 2" outboard of the fuselage, but so far so good!

I will say that every time I fly the airplane, I like it a little more!

Hope I helped,
