That's going to look nice Brad.  Very clean work on the stringers.

you got it John.  That's my Dad's old Erector Set and it does come with the electric motor  Smiley

I'll post more photos later, but I did the cheek cowls from Balsa and managed to slowly sand and shape them to the best fit I've every accomplished.  They started at 13 grams total and now they are 2 grams total and I still have some hollowing out I can do.

Erector set. That looks like the deluxe version with the electric motor.

I'm going to try a couple of options.  I will check the weight of my plastic before I do anything  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?

It would have to be VERY thin plastic - almost cello thin after forming.  The dorsal extension on my F105 (a fairly largish model for Rapier power) is about 4 inches long made from a very light (almost pithy) 15sq strip.  once shaped and hollowed, it weighed <0.5gr.  Lots easier than carving a buck, polishing, setting up the vac box and drawing the whole thing.

Peanut NEED added lightening Grin.

My two cents to a great effort!

Brad,
I'd be tempted to do the canopy and turtle deck all one piece plunge/vacuum formed.  Depending on the thickness of the plastic you could have a very light piece.... 

What a sleek looking model.

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.

I've thought about the same and might try to pull a full vacuum form before I cut it apart.  My main hesitation is I have a personal issue (mental  block) against using plastic forms on my builds - other than canopies that is.  But the idea of quick and easy is a strong draw!!!  The single piece of wood now is under 1 gram and is only slightly hollowed out.

I wonder what the weight difference in the turtle deck would be if it remained as part of the canopy plastic, albeit painted?  Sure would be a temptation for me...lazy me.  Grin Grin

Looking good, Brad.  Smiley

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
