there is a lot of room, but its only going to have half depth. I am putting my muffler up there. My cockpit floor will be about where the bottom seat cushion would be on a real helicopter. So there will be 2 seats with side panels and instrument panels.

It will be all balsa construction first, then the panels will be covered with .020 styrene with cutouts and then these instruments behind the cutouts.

I'm sure its not going to be of the grandeur of the 1000 dollar cockpit but I dont need that much scale. And this costs me like 10 bucks

I just looked up his invoice to be sure. The cockpit was 650 Euros and pilots to fit were 150 euros each.

So the cockpit was $930 at todays rates.

well I have a bad batch of either resin or the hardener. 24 hours later and I have a sticky helicopter. Lucky for me that acetone removes uncured polyester resin, its a lot of work but I have it almost all off and dried out.

I went to home depot and was looking at Kilz, looks good, I also saw this other product called "wood floor sanding sealer". Hmmm, gonna try that and apply it with a little sponge roller

I'll let you know later how it works out

It's a filler composed of micro sized glass beads that is strong light and sandable. You add it to your epoxy for filler.

I'm using this stuff from now on. Its the bomb. I coat and most the grain disappears. Sands easily

its a wood floor sealer/filler Do not use a brush! use a little foam roller

so here's the whole helicopter with one coat. Kinda looks like a sand camo

this whole week will be sanding and filling, then by the weekend I hope to prime, and begin penciling in the panel lines

the cloth is back on the vertical tail where the wood joints are small and the wood gets thin.

no cloth anywhere else. I've scratchbuilt a lot of large scale planes, my biggest was a Grumman TBM avenger that had a big 1.5 supertiger in it. I didnt use glass on it either, except on the tail where there was alot of stress. never had any problems.

I personally dont think this thing needs it. Its a pretty tough box, maybe it would be a good idea for hangar rash and transport rash dents.

should be like any other properly filled balsa plane. just keep filling and sanding till the grain goes away. This floor stuff is pretty good actually. 2 heavy coats and most of the wood grain is gone.

I have automotive primer that is flat OD green, the color of the finished model.

raptor 50 with an OS 50 hyper, I dont know if weight is going to be too big of a factor

One thing does concern me and thats center of gravity. There is a lot of weight, a lot further back than just a stock raptor 50. If I pick up weight its going to be up front in the nose to get the thing to CG properly

3 coats of the floor fill stuff, lots of sanding and now the first coat of primer. It is nicely filled, but I see pits and irregularities I need to go back and fill in

Oooh, hold on

this is a nitro bird??? I'll be really interested to see how your finish holds up then. I thought like all of the Dr. Tim builds here that it was an electric. Not just your finish, but the interior of the fuse. I musta read that wrong, didn't I???

yep its nitro. The final finish inside and out will be completely covered with Dupont chromaclear matte finish clear. Its top of the line 2 part automotive paint, resistant to all chemicals. The grey primer is 12 dollar per can automotive primer from the same shop. I paint motorcycles as another hobby. This is just some of my leftover dupont products. This will go over my rivets and panel lines as well.

Here you can see how easily that filler block sands. Man I love this stuff. My exhaust exit is a copper tube that will protrude about 2 inches below the bottom of the fuselage.

aha...knew there had to be an answer for that one. Looking forward to the finished product. Love working with wood, just not fond of laying up glass, which is why I asked.

hey Grant, sorry for hijacking your thread, just thought it would be good to keep up with both builds in one location.

More sand, fill, sand, fill. The grey is a filler primer, the green is the final color. So the two removable upper sections are almost done. I think I am going to split my trans housing as well.
