Seems like there is a huge infatuation with R/C Pee Wee engines and the like lately.

Here's my attempt to create an R/C Pee Wee engine with a modified version of the 3D printed backplate. I stretched the body of the backplate by .25" to make room for a throttle body. It will use C clips to secure it in place and o-rings to seal and prevent leaks. It should be able to kill the engine when fully closed. I have parts on order from McMaster Carr and will print a few to try out. I need to order a support filament that can handle nylon and will use my dual extruder printer to print these. The throttle body gets pretty thin at the o-ring area. Hopefully the carbon fiber Zytel is strong enough for this. No guarantees. It might end up in moth balls like the 3D printed all bearing crankcase TD.....

Looks amazing. The detail into the design is nothing short of amazing. Wish you luck on the printing and that it works out good for you.

Jason is trying to do it better (mouse trap) than the guy in Japan that has a Pee Wee throttle.  Bad Xmas Gift

AHHHH! !
I look at those 3d CAD renderings of the Backplate and throttle barrel and get shivers up my spine thinking how long and difficult it would have been to produce those types of drawings back in High School Drafting #1 & #3 pencil on Velum paper, Hey Roddy, Can I borrow your French Curve? anybody got a protractor?
 AAHHH !  again  I'll need an eraser too.
 I still get complemented on my hand writing when I take the time to print like was taught way back then.
I'm jealous of you guys who brought yourselves up  into the 21st Century learning CAD and 3D Printing ! !  

Hey Jason, If you go into production......I would order a couple just for fun! !

How you supposed to mount the engine ? .... Big hole in firewall with no strength left?...or long spacers that will surely vibrate loose?

From what I can see, they should mount normally, just the same as any horseshoe backplate. It should just mount flush. Air can draw in around the needle valve and fuel line like any similar backplate.
