Suggestions for dual TB intake and WOT switch

i've thought of using 1/4" drive universal joints but you'd have to make sure they didn't have any slop in the joint.

If it's strong enough, it'd probably work well, if you can build a frame for it to stop it from flexing... :thumbleft:

Enough force to quickly accelerate/decelerate my ~20# 1:6 scale "Monster Buggy" to ~40 MPH. The brake on that one is inboard and only on the rears... http://www.traxxas.com/products/nitro/m ... onster.htm This is also not the largest R/C car available so if you're worried about strength go with parts from a 1:4 scale oval-racer. No frame should be needed, attach directly to the throttle shafts.

Kohburn,

That's what pre-load is for! If there's enough tension to retract the throttle cable, there shouldn't be a problem. Build a little rig for screw adjustment of the second plate and run with it.

Each throttle has an independent idle adjustment screw.

Yes, but don't you want to be able to fine-tune where they begin to open relative to one another? From my understanding of the rig you don't want the first opening to 5 degrees before the second starts to move...

That's why you build an adjustment into the transfer mechanism.

Isn't that what I suggested?

ever notice that the best setups also look good?
no one here is saying make a plastic deco cover. no one is saying polish the parts.
it just doesnt look well thought out. thats all. and, you are 100% right in saying it doesnt need to be.
I'm sure if I posted pics of some of my work on my mustang, I'd get the same reaction....its wasnt pretty - and had no reason to be....

I don't know..... Mike Smiths DOHC upper intake look's like a Shit but it works vary well.

and kohburns looked sweet, but blew apart (not really a malfunction of the intake). There will always be exceptions to the rules, but primarily, if someone takes the time and care to make something look halfway decent, it will mean he took that same care in the rest of the process.

Just my $.02
