Hi

This may sound even dumber.  What is the advantage of the metal backplate as a replacement for the stock item?

Cheers

Mike

It's lighter, it doesn't cold flow and it's shiny. Someone was making them with O-ring seal so you don't have to mess with RTV.

Lol, so what’s a cold flow?

Cold flow is a type of material deformation that is defined as the tendency of a solid material to slowly move or deform under the influence of mechanical stress.

      For most people, the only advantage is that you can change to socket head screws and then crank the crap out of them and not break corners out. In general use, not much of advantage really. If you use truss head screws like those it came with and don't over torque them, or use flat washers under socket head screws, there is absolutely nothing wrong with the stock back plates. There used to be several guys making and selling metal replacements but most have dropped out or are no longer with us. Availability of the metal part is the biggest problem. I only keep a few metal units on hand in case I pickup an engine with a screwed plastic back plate and I don't have any plastic ones to replace it with.

Came across this kinda late.  I built a Smoothie, pretty much stock with an LA46 with  stock 30-30 muffler.T  he venturi was changed to a 1.24in high straight stack and a 0.260 id.  Stock needle valve. 10%nitro, 12.5% synthetic, 12.5% Castor.  After some fiddling, I ended up with a 11/7  3 blade Master Airscrew.
One minor modification- the kit came with slightly long sticks for the stab leading edge and trailing edge.  I like a plane with a "solid feel" so the stab came out a bit oversize,  24in. span, 7.25 root, 4.5in tip = 141 sq.in.

Turned out to a good flying plane with no bad habits.
