thanks!! Is that metal motor mount all it takes to remove vibrations? Also, are there any additional tricks that help remove vibrations?

I use the plastic mount that came with the kit and have never had any vibrations. I do not see how the aluminum one would stop the vibration. Mount it properly and you will have no problem.

I also use the plastic mount and because my motor didn't really match up I'm actually just using 2 motor screws to hold the motor to the mount but still no vibrations.

The alloy mount also gives 300% better cooling then the plastic one which does not have any, apart from the small bit of space around the edge.

Yes, I and many have used two tricks to help remove vibrations. First install a piece of square wood dowel between the motor mounts on each side in the slot at the rear of the mount, epoxy in place. second use fiberglass cloth from the front air intake bottom back to the cooling slot in the bottom of the fuselage and epoxy. You need to remove the mold release on this area first with an alcohol wipe. these two steps will stiffen the front of the model which is very flexible.

that depends on whether or not the videos show my pathetic landings =)

I looked up the size of the 81's and they are indentical to the 82MG's and that servo will not fit into the wing cut outs. The HS-55's do fit but have some wiggle room. So my question is when you say, "I use the 55's on some lighter models" are you telling my not to use the HS-55's? Again I was planning on using these for the aleron and flaps only, 82MG's for the tail control.
TIA,
Brian

Sorry! I'm not telling you to not use the 55's. I prefer the 81's and made the wing cut out larger for them. The 55's will work and are OK to use. Again, sorry for giving you the wrong impression.

That pic helps a lot! Thanks! The kit comes with a plastic crossbar. How does the wooden one removr the vibrations though? Sorry I'm asking so many questions, I just don't want to ruin my FC by vibrations. Lol

Tighten everything really really tight up in the front. That's what I did and I ahve no vibes with a decent power setup winging a 12x6.

I hated the 13x4, I probably already mentioned that though. Godd example of why we need some pitch on propellers
