Twin Star motor & paint questions


I bought a Twin Star, thinking of painting it with enamels/oil based paint, white & red(to pilatus colour scheme). Naturally, extra weight would need to be accounted for.
Ineed to know: 1:would MPX gearboxes be sufficient?, was thinking of in-line like Speedgear 400s to enhance appearance. Been told that very good, ubiquitous, Gunther props could be improved upon.
2:Method of applying paint, I was informed that if the enamel tub of paint was sitting in a pot of boiling water, that the brushmarks would disappear when it dries. Anyone comment? Would this paint be too heavy? would it need gears?
Please help!

use water base paint . you can find some spray paint like formula - U that will work on foam.

I painted mine with HUMBROL Eneaml paint which is normaly used with plastic models. If your not sure about the paint, just paint a little bit under the canopy or somewhere you dont see. And see what happens.

I havn`t tried gears, but 8 2400 cells and the stock sp400 flys great. Loops from level flight. Gunther props are great. (the stock white ones.)

I used sea grey for the upper surfaces and gloss white for the lower (RAF Coastal Command ww2) acrilic paints applied with a brush. The white needed about 3 good coats, grey only needing one. The weight didn't seem to be a problem as it flys fine on a 7cell pack of 2400's Nicads.

I can post some pictures soon if you like. semmyroundel

Water based paint would be best. I used oil based spray paint on top of brushed on water based varnish. The trick is to let the spray go on lightly without building up too wet, several thin coats instead a heavy ones. If it gets soaked, the solvent is going to work it's way through to the foam and melt it.

Get some prop adapters and try other brands on the S400. I'm happy with Master Airscrew 6x3.5.
