I want to build a Porsche 917,but the available kits seem rather pricey.I decided to use an HO Aurora a/FX body as a pattern to make templates for a 1/25th scale version.May not work but I will give it my best shot.The templates were made out of .80 styrene. 
Interesting. Subscribed!
After some thought.I decided to cut a piece of 2by 4 into the wedge shape,clamp the plastic to it ,and use my wife’s hairdryer to heat the plastic to assume the correct shape. 
All of the ducts have to be shrouded and the wheel vents have to have arched grilles.Much work ahead but it is looking like a race car.Much bigger than 1/25th!More like 1/16th! 
Put on the rear deck blisters. 
Made and installed the rear valence with louvers. 
Primered it and painted it silver prior to painting it white. 
Hi Phil,
About’s how long is your model. I’m having difficulty judging by the pictures.
8 and 3/4 inches.It appears to be larger than 1/25th perhaps 1/20th or 1/16th.
Painted one of the racing stripes.Due to the rather elaborate masking ,I have to wait until tomorrow to paint the other one. 
Cut out the RC Grafic and carefully airbrushed a light coat. Heavier coat(s) to follow. 
I am pleased with the result! 
I had to hand paint the red stripes,Not perfect but i will touch it up until i can get them as good as i can. 
Very unique answer for building the car you want. Well Done
