Thanks Steve. I have an idea of how Im going to deal with that, just havent gotten to it yet. Heres a quote from Todd regarding the way he mounted his elevator servos and a pic below. I know his is working really well. If theres anything under the pipe floor supporting the servos maybe he will explain when he reads this. I figured since I built the bottom of the servo mount tray out of 3/32 ply and glued it to the floor it would provide most of its own reinforcement since it covers a pretty decent surface area.

I used the hyde control horns from Central Hobbies, and for the elevator I used 2 servos under the rudder,
mounted to the pipe floor with the carbon pushrod set from Central Hobbies

I would leave the pipe floor in, and for the motor mount just use a lite-ply ring behind your motor mount
to keep the blind nuts from pulling through the balsa firewall. That is how I did it on my ARF Genesis
and it works great. My Genesis ARF with a DZ 140 weight 10.7 oz RTF with NI-Cads
The firewall on this thing is 3/32 glassed balsa eh?, All im planning to do there is put a plywood ring on the back side for the blind nuts on the motor mount to have something to grab into. I have some pics from Todd and I know his has held up fine.
Bill, I mixed some epoxy and micro balloons together and let it barely get tacky so it wouldnt drip.. As Troy said in the instructional he just posted I "lubed it up" on the ends. The guide tubes stick out about 1 1/2" past the end of the balsa rails so there was no danger of getting glue on the pushrods when I inserted them through the fuselage as long as I got it in there correctly on the 1st try and didnt have to pull it back out. I got a good bit of glue back there. Another way I think I could have done it was with a hypodermic syringe with a large needle like a turkey basting syringe. You can insert the needle through the pushrod exit hole and apply the epoxy to the former that way but it has to be pretty thin, and I didnt want glue running everywhere. . ..
Anyone please feel free to contribute if you can see a better way to do any of this, Im honestly open to suggestions and do not claim to be a pro. Im just documenting my build so maybe others can learn from what I do right and wrong. I just want to build it light but strong.
