But I will be moving my CG back to 350 for this weekend and put a different servo in the rudder.

I don't think slop is causing the jitters, I have the same issue with the 8711 on the rudder of my Sback. Some of the older, non programmable digital servos, like the 8611 and 8711 had very tight dead bands. Since there is no load on the rudder on the ground it messes with the servo (don't remember exactly what's going on). What I did, after reading a lot of posts on the issue, was glue the fuzzy side of a small strip of Velcro to the top of the fin. It just barely rubs on the bottom of the rudder counter balance, not enough to effect the rudder, but enough that the servo sees a tiny bit of load, twitching went away.

Hey guys,
Check your ball links... While going through my T3, I found the ball is loose inside the plastic on all the stock links. It's not alot, but I can spin the ball easily with some slop. I'm replacing all mine with the Dubro monster ball links and titanium rods.

Can someone please give the T-3 fuel tank dimensions? measurements don't have to be exact, but close. Also, is the main tank a true 7.5L (256oz) ? I'm looking at this tank for a different jet project. Thanks...

Although the manual states clearly that we have to use 1" arms, (except for steering), I have in my workshop 20-25 pieces aluminum arms (25T) 1.2" and 1,5" lengths available. What lengths did you use guys for your T3? Is there a problem to go with the sizes that I arleady own?

Thanks in advance,
Makis.

Did you end up putting the door back on? I’m having a tough time setting my hinges. Any tricks to it?

One single heavy duty Dubro large flat pin hinge in the center. Made a wood block shaped to the strut, position and glue onto door. I tape it when transport. The air keeps it closed during flight.

A fellow modeller from my area has found that 22mm arms give the correct geometry on the T-3, FWIW

1 inch on flaps, ailerons, and elevators. 1.5 on rudder. Whatever you want on steering. All my throws are around 100 on all surfaces.

Hi guys, I'm confused, please advice.... The little plys are options for aileron, elevator and rudder servos? Did you used them during building process? And the screws... I've got two sizes in the hardware pack, which size is the one to screw the servos?
Thanks in advance,
Makis.

Longer screws are to hold servos in. Shorter ones I believe are for the servo covers. I did not use the plywood pieces.

I used the plywood pieces to shim the servos up toward the hatches so more arm stuck out.

Thanks for the input guys, another question: Did you use some kind of wood glue on the screws before screwed them onto the wood? Just for safety?

I used duco. Bought it off amazon. It’s just like ambroid. Holds the screw in but releases when trying to get a screw out. Great stuff.

Hi guys, did you use the fuel stock fittings for this jet? I intend to put a JetsMunt 200XBL and the fuel holes seems to be very small for me, in my opinion....
Any related info will be much appreciated.
Thanks,
Makis.
