The 'What did you do in your workshop tonight?' thread

[Jetpainter]

Tonight I matched the aileron servos in the Sukhoi using the Powerbox. It was pretty easy, and they really did need it. I used my amp meter and before I started one wing was drawing over 2 amps. After I was finished they were all .08 or less. You can only match them at center and full deflection, but it's better than nothing and way better than it was.

I also wired the gyro and got it setup.

Putting the wings and stabs on it in my family room was a treat. It's pretty tight.

I like how you decorated the family room in "Aero-Monolith" . Reminds me of another family room that was done in "Aero-Behemoth". For myself a modest "Modern-Aero" works just fine .

I did get my Extra fitted with a new RcExcel A-02 6-12 volt ignition and rebuilt the Walbro WT 908 carb. And because of this I am now a believer that "Black Holes" can exist ANYWHERE!! Ya see......that tiny little spring, you all know wich one, took a trip to another dimension for about 2 hours. Yup! Vanished. Had to go calm myself and get on my knees and pray. Well it returned unharmed and found its way back home thank goodness. Just to check things out I flipped the engine on choke four times and fuel was knocking on that springs door . Guess I will have that engine "Running Scared" now .

Dimes,
In the above post in the top pic, the top ply piece look's to be coming loose. Is it?

There is actually a 50cc and 61cc airplane behind the Sukhoi that you can't see.

I finished up with the Sukhoi today. Tony, the owner is coming to get it later if it stops raining.

The wiring for the gyro is about as neat as I can make it. There is so many wires, and only so many places to go with them.

No. Just a poor fit in the slot due to the triangle gusset.

Before the Sukhoi left tonight, Tony and I put the cowl and the baffling back on and assembled it in my garage and tested everything again. It's ready to fly, but it's going to rain all day tomorrow. Hopefully it will fly next Sunday. He's saying I'm doing the test flight, I guess we'll see when the time comes.

Question on the Cortex. It has only 5 outputs. This large plane I think has more than 5 servos that need to be controlled, how did you connect all the servos. Thanks.

That Sukhoi is in a league of it's own.

This airplane uses two aileron servos in each wing, one elevator servo in each side and two rudder servos. The PowerBox has servo matching, so going into it for flight surface controls you only have right and left aileron, right and left elevator and rudder. The PowerBox splits each aileron and the rudder input into matchable outputs. So the five in and outs on the Cortex are all you need.

The matching on the PowerBox is easy to use, it has a feature that locks the stick input for you to max throw in either direction so you have both hands free to push buttons and get the travel of the slave servo to where you can slide the ball link bolt in freely. I used an amp meter to fine tune it after that.
