Extreme Flight Extra 300 91"

[Scooterpilot]

Glued the rudder control horn in place. Since I'm going to use push/pull on the rudder I removed the covering from the servo bay on the back right side of the fuse. I installed four servo screws and screwed them into the wood, removed then and soaked it with thin CA.

Those of you who installed a DA70 and configured your rudder servo push/pull (at the back of the fuse), I have a few questions:

1. Where did you end up mounting your batteries?
2 Where did you place your battery switches?

I'll have three batteries

1. for the ignition
2 Two to power the servos
3. I will need to install 3 battery switches.

I see locations up front next to former 1 for the ignition switches ; however, I don't see any other locations for other switches?

All comments will be helpful.

Thanks a bunch

Chuck

PS HAPPY NEW YEAR

I glued small wood blocks next to the attachment points for the cowl, adding a bit strength. Then I opened up the hole for the rudder using a wood reamer so the knuckles of the hindges would fit nicely without any binding. I rough sanded the robat hinges. Mixed the epoxy and using the stick layed the glue into the hindge holes. I then applied epoxy to the hindges on the rudder, just the last 1/3 of the hindge. I inserted the rudder hindges about 3/4 of the way in and stopped. I used a paper towel to remove any excess epoxy. Then I pushed the rudder into the fuse and set the gap. I used denatured alcohol and cleaned all the hinge knuckles and all along he surface where the rudder and fuse meet. After cleaning I placed a piece of masking tape on top portion of the rudder and let it cure.

Installed the tail wheel. Then I installed the fuel filler. That was easy drill a hole, make sure the covering is cut clean, put thin CA on the wood and install the fuel filler.

I decided to remove the covering over the pipe tunnel. I cut it long so I could iron it back onto the wood in the tunnel. After that I taped the area off with masking tape and mixed up some epoxy mixed with denatured alcohol. I sealed the whole tunned making sure to hit the covering where I had just ironed it to the tunned so it wouldn't come loose if it gets exposed to fuel.

I had to cut all the covering out of pipe vent cover which took time. I iron it and sealed it too.

More done tonight. It's actually beginning to look like an Extra. I sealed the hindge gap for the rudder. Then installed the rudder servo and linkage. After that I installed the stabs. I double checked the throw on the stabs to make sure they were even and they were not. I checked this by using two carbon fiber rods and taping one to each of the stabs. As the stabs move up and down you can easily see if the rod stay aligned.

I have low, medium and high rate set up for the stabs and the rudder. Whelp. that's it for tonight.

I made motor mounts from wood. They are 3/4" thick and should do the job. I did fit check to make sure everything aligned properly and the wood motor mounts fit properly. For once, I won't have to sand they fit perfect.

I also made a JR plug and installed that on the wire DA provided with the motor. This will plug right into the switch, it worked fine.
