I've cleaned my work bench and started a new peanut scale build.  The DR-90 Nemesis racer.  Yes.  I'm building another race plane  Smiley  

My careful selection process for my next build consisted of:
1. Peanut scale
2. What did I have plans for that were ready to go

So I have dove in and I am working on the wings and tail surfaces.  I'm thinking I will break down and buy some small airbrush gear for finishing.  If I decide to go with white like the real plane, I don't want to 'chalk' my tissue.  That is slow, messy and doesn't really give you a solid white.  I'll be thinking about it during the build.

Here are a couple of shots of progress so far.

Another nice one, Brad.  Look forward to seeing it come together.  When are you going to do a Pond Racer?

I agree with Mike. The Nemesis is too easy after the Pushy Cat Smiley

You will have a display cabinet full of these before long.

So yes.  The Pond Racer is on my list..... but it's like building three fuselages!!  Ha.  Sometimes you need to build something clean and easy.  A building 'sorbet'.

However, this Nemesis is not easy.  Look at the curves and needless to say the cheek cowls!!  I have not yet been really happy with my cheek cowl work.  They look OK from about 4 ft. away, but I really want to figure out how to craft a beautifully shaped and perfectly fitted cowl around multiple curves etc.  Look at the Nemesis cowls - they are crazy.  Tons of swooping, compound curves that have to meet the same - and match side to side.  Wish me luck.

I do have to say, after my last plane (Pushy Cat) with a 24 inch span, this is tiny!!

Brad check out the Wild Turkey and add it to the list. A real different race plane.

Thanks for the great lead on the Wild Turkey!!  Awesome plane.  I've saved all the photos/info I found on my first search pass and it's now on my build list  Smiley

Brad how about doing a plug for the cowls in modelling clay. This could be used to produce a solid plug in plaster for perhaps vac forming or for forming sections for carving?

Very interesting idea John.  I'm also interested in locating 'blue foam' that I've seen people use that is easy to carve.  I have not found a good, easy to shape foam yet.

I did managed to sneak in a little build time last evening.  I got the inner fuselage box framed out and I have my top and bottom formers ready to go.  I even noticed that I have to notch the bottom of the top formers to allow for motor clearance - prior to installing them!!  Smiley  This proves that I can learn from my past mistakes  Grin

I've decided to build the canopy and turtle deck from a solid piece of light balsa.  I'll vacuum form the canopy and probably tint it a bit darker.

I'm building out the fuselage, trying to make it straight, smooth and round without breaking too many stringers along the way  Grin

Wheel pants, landing gear and stringers!!!  Oh my.  Here are some in progress shots.  I'm not going to be able to put off the cheek cowls much longer.

Lots of stringers Brad - must be very fiddly! I'm curious about the horizontal plate with binding, in front of the landing gear block. Is that an extension of the landing gear?

Happy building.

John, that piece of wood is a brace.  No bindings at all, it's just a bar code that was stamped on the wood  Smiley  I probably should have selected a clean piece of wood.  I have braces front and back of the landing gear to the closest former, otherwise the gear only mounts to a 1/16 stringer on either side.

I'll post more photos soon.  Super busy at work.  It's like everyone is taking "crazy pills".

 Smiley  It's on my list and I have been collecting reference photos.

My next race plane will most likely be the "Hot Stuff" racer formerly known as "September Fate".  I contacted the actual pilot of the real plane who sent me 3-view files  Smiley

Just a few shots of my recent "work".  Meaning fixing stringers I break  Angry   I did get the wheels pants all shaped up.

Quiz: does any recognize what the RED metal box is?

You got it!!  That's my Dad's old Erector Set.

I made the cheek cowls this weekend and carved them from balsa.  I post more photos later, but I did my best job ever of slowly carving and sanding them to a very close fit.  They started out at 13 grams total and are now 2 grams total and I still have a bit more to hollow out.

Here are the 'almost' finished cheek cowls and chin scoop.  I might carve a second chin scoop - this first one got a little thin after reviewing photos of the real plane.

To me that looks pretty complex but a jolly nice build.  Having a hang up about producing heavy models, notwithstanding attempts to achieve the contrary, don't publish the weight please.

Those cowls fit well Brad. Lots of sanding/fitting work there.

I have started to cover the plane.  I'm torn between painting it or leaving it 'natural'.  I like to see the structure, but the real plane is white.  I'm leaning toward picking up an airbrush and giving it a go.  I'm covering everything i.e. wheel pants, cowls, turtle deck, instead of adding weight with primer.  It's gone fairly well.  I'm applying the Isaki tissue damp, and it formers very well.  My plan is to cover everything, then assemble all the components into the final plane, so I can seal all the seams with narrow strips of tissue.  Trying to get the smooth composite look.

I think I would be tempted to leave it natural plus trim Brad. It gives you the option of a lighter model and a better flying model.

John, I'm tending to agree with you and I'm leaning toward leaving it natural.  I think the plane 'reads' white due to the absence of color.  My new airbrush setup arrives today, but I need to do a little practice before I start shooting an almost finished plane!!  It's been many years since I wielded an airbrush.

Here are some shots as I mounted the wings, turtle deck, stabilizer, rudder, chin scoop and cheek cowls.  Over all I'm very pleased, however, my cowls don't fit quite as well as I thought once the fuselage was covered.  Nothing has been shrunk or doped yet.

It may be possible to add a strip of soft 1/32 sq or whatever the max gap is around the mating perimeter of the cowl. Then tape a piece of say 120 grit to the fuse where the cowl fits and sand the cowl down so the strip is only left where the gap is.

A bit fiddly but it should work if you manage to tape the sandpaper down tightly without creases. This would need to be done after doping and only use a low tack masking tape.

One of the benefits of managing a creative team!!!  This is a tough font to find so I sent a photo of the plane to the graphics team with the rough size I needed each element.  Then I just added some "experimental", etc. items in various sizes and put clear stick material through the color printer  Smiley  I feel it's cheating, however, it's a curvy font, it's small and has a black drop shadow - all very difficult with tissue.

I have one coat of EZ Dope on the plane and it shrunk up great.  One more light coat, then the decals.
