RE: CA Model Epsilon 90 building thread!

I will put this build on hold for about one week, as I will travel to Madison, WI for business reasons. I will probably buy some DS821 servos and a R790 receiver, just to stock them. Any idea about...

RE: CA Model Epsilon 90 building thread!

I will have this in mind, dbacque. I already saw many people do so with CAModels' planes... maybe a material issue.
Thanks for the advise.

Here are some other pics, showing the mounted cowl already painted. You can also see part of the belly and the painted muffler tunnel. I'm thinking about giving it a finishing clear coat to ensure...

Yes Martinoto, dbacque apparently had the same problem that I had... I realize about the softness of the balsa wood not as early as I would like [:@]
Anyway, I managed to mask those sections...

To tint or not to tint...

As nobody here has a method for tinting the cockpit (and I can't get Rit dye here[:o] ) I did figure out how to make the false plexiglass translucent, but not crystal...

RE: CA Model Epsilon 90 building thread!

Here's the engine.

It ate 5l+ (1.3gal) of 0% fuel. It's really amazing how this beauty burns fuel! The carburettor was wide open at all times, but the mixture was set extremely rich; it even...

RE: CA Model Epsilon 90 building thread!

More work last week...

The fuselage is completely covered. Not a easy one: the use of a sock over the iron is imperative if you don't want to hurt surfaces [:@]. I've mounted the cowl just for...

I've painted the cabin floor and covered the fuse top, as I mentioned before. Also glued the stab in its place. To achieve this, I've put the wing and stab in their place;...

RE: CA Model Epsilon 90 building thread!
