All,
I just purchased a DD with piped MVVS 40,and Fut 148 servos installed.It had been flying like that,but I'm wondering if the servos are strong enough.Also,it's covered in Monokote,and Ive heard stories of covering blowing off these things.Any thoughts?
Thanks,
Erik

Mine has a OS.46 on it, and JR507's, all I had, I also did a monocoat/ultracoat job on it, in a full throttle straight down dive I pull full elevator at about 20' and I cant get it to explode or anything, looks like it bounced off a wall!! Funny to watch.

So far, about a year flying like this I have had no servo problems, but with a faster motor like yours I probably would step up on servo's but if yours are working...

i've got same combo but ballraced standard servos. i did have my covering come off after it lifted near the engine mount, i've now got SolarTex on the bottom to stop holes and i sealed every joint with tape. any small hole i see is repaired right away with tape before it flys

seal the front leading edges with clear packing tape. Do it neat and you will not even see it. That tape is strong as hell and wont come apart..

I noticed in the instructions it mentioned to use Ultracoate only. I figured they said this for a reason so thats what I used.

A few folks at our field have DD also and did have them explode in the cooler weather. The monocoat became hard and brittle and somehow caused it to fill with air and fail. I have never seen it happen but from what they say it happens. I'll stick with their word for now.

As for the joints i used the top flight colored stick on covering (neon orange) on the leading edges. I used it mainly to make it more visible and sealed it with thick CA glue. It worked great. Well till i crashed it, so guess in a way it lasted the whole life of the plane.
