Lookie what I got. 20 ga servo extensions by Electro Dynamics. Very nicely done. I got the wings finished after installing the extensions. I still have to mount the intake after I get fuse joined.
Fished the rudder extension through the sleeve. It has a pull string. Then glued on the vertical stab.

Step 1....follow the instructions.
step 2.....oh crap!
Recovered by threading it the sleeve with airline.
It was difficult to get elev and rudder servos connected as the fuselage is TINY!
Starting to look like an airplane
Finally it's an airplane
I have a few little nit noys to clean up but it's basically done. Picked it up last Thursday, started on Friday and working basically half days complete today. Final Radio installation will be done by the owner.

Test flew a customers MB-339 on Sunday, he’s had plenty of issues with the retracts, the counter balances on the elevators are way out, but it actually flies nicely, coped well with a flame out when the main clunk got caught and the header tank ran dry!
I rebuilt the retracts with helicopter shim washers on the slider bar, matched the frames and the units seem to work reliably now, I did have to change the retract extension leads, connection into the gear controller was poor, if you wriggled the connector the main gear would start and stop!
