after doing a search on this plane here I have found out several things about this ARF.
you gotta replace the fuel tank because it splits.
the elevator and rudder pushrods interfer with each other.
is this because the instructions have you mount the horns 1/2 in.
from the end of the elv.?
would mounting the horns 5/8ths. out fix the problem?
I am thinking about not using the arf o matic engine mount and mounting the engine at any angle other than inverted(TT 46) any balance problems for those of you who also used a two stoke?
if I side mount the engine should I block off the hole in the front of the cowl?
I have read reports of the horz. stab breaking off has anyone tried poking a pin hole and injecting thin ca. into the LE to harden it? whenever I asemble an ARF I always poke pin holes along the cut lines on the horz.stab and paddle epoxy into the holes. or is the stab breaking off further out from the fuse?
TIA for any info on this plane .Greg

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,

Well all I can say is....
What a great flying airplane! At least that was the impression I was left with after getting to fly mine for 1 and half flights last Monday night.
The model was built as per the instructions with the only mods being:
pull-pull cables for the rudder control
12 oz. Sullivan fuel tank
mounted the O.S. 46FX about 60 degrees off vertical
boxed in the radio compartment to provide for a switch mounting point
Other than that it was all basically built out of the box.
It appeared to everyone that was at the field that the airplane lost the rudder. She was in a dive at about 30 degrees nose down while exiting a loop and the tail simply came apart! This wasn't nearly as insulting to my pride as was the impact with the tree that followed! For those that are iffy on the single wing holddown bolt......it didn't budge! The firewall and cowl however got smashed when the model fell out of the tree and impacted on the nose from about 15 feet. This impact even broke/bent the aluminum engine mount!
Post crash inspection showed that the left horizontal stab had broken away completely but not before the elevator separated from it, 2 of the CA type hinges had pulled out and the third had torn through in the middle. The same thing happened to the rudder hinges and I have yet to locate the remains of the rudder itself.
If H9 decides to replace this plane I plan on making new tail surfaces out of 1/4 balsa stock and recovering them to match like the originals. Also I will NEVER use their hinges again, instead I will opt for Robart's hinges that have worked so well for me in the past.
Well, I hope everyone has had a better time flying this week than I have....it's back to the Ugly stick for a while for me!
Take care,
Scott
