Powder Coat on 4130
I have a Baby Belle helicopter that has the entire airframe powder coated.
It was done in 97. No problems to date. I know of several other
helicopters with powder coated airframes. No problems have been reported.
Yep it is heavy. Yep it is tough. If you have to remove some to make a mod
it takes a bit of sanding.
Big mistake was the color black. Friend had his powdercoated yellow and a
small crack showed up like a big black line.

Hello
Was watching American Chopper this evening , I see things on that
show that make me cringe but I do enjoy the antics of that family, they
always refer to Pipe if they are building a frame out of Tubing etc. ,
this evening they were working on a dragster bike for NAPA and when it
came time to paint the machine they said that powder coat couldn't be
used because of the heat involved would ruin the 4130 tubing , seems
like a lot of engine mounts and other A/C parts will have to be junked
, would like to hear some thoughts on this concept , as an A/C welder
it is of interest to me.
Thanks

Powder coating won't hurt 4130, but is NOT RECOMMENDED for aircraft
Responding to an "old" thread here, but powdercoat cures at about 400 deg.
F.
Still not enough to change 4130
Powder coating is done at what, 275 degree F? I gotten my airframe
hotter than that by cussing at it when members wouldn't meet up properly.
4130 will see it as a pleasantly warm temperature, suitable for shorts
and maybe a light sweater.
