Default DPCM repro Guillows DH-4

Hello all, Dave has released his laser cut 27" span repro of the original. He offers it in original and in lightweight. I have mine all framed up and almost ready to cover. Dave left out one frame part from the rudder but this was easily replaced. There are some minor discrepancies in the fit of the struts but I believe this is just the way Guillow made it. I used the Spektrum 7.4 V brick and an outrunner 180. Battery will load from the underside with a magnet retained access hatch. Upper cowl, which I separated and covered in 1/32 sheet balsa, is also to be magnet retained to allow full access to the engine compartment. Comes in handy after faceplants and if you have to adjust the thrust angles.

As always Dave replaces the vacuform parts with balsa, this is a survivability plus particularly re the cowl.

So I am looking at the wings and the seem a little fragile. I am wondering if I need to add a hardwood 1/16" top spar? These wings flex a lot. Dave calls this the lightweight - uses 1/16" x 3/16" instead of 1/8" x 3/16" spars. There are two soars for the upper wing but only one fir the lower. My experience with biplanes is that the lower wing is the one that gets whanged the hardest and most often. Your opinions?

Default Almost ready to put wings, struts, and undercart on

Making up some details like vac form Easy Bilt pilots and guns, the US ones used a weird Marlin MG. It's a pure flying model I am not going nuts on details - I may even leave off the aft twin Lewis guns.

May cut the pilot and gunner down get the heads lower.

Can you suggest a paint that might stick to an orange plastic GWS EP Orange plastic prop? Maybe Testors enamel thinned with lacquer thinner.. or rustoleum out of a can?

Nice work there Griff!

Any paint with lacquer thinners should probably be avoided on plastic parts, but maybe if you put it on in light coats it would be ok, it might 'self etch' to the surface!
