This is really a great system for subs if you can fit them in your WTC!
My sub will measure 94.5 long and have room for them but they would work well in the Revell subs if they can scale down the size.
Check out the www.nextengine.com 3-d scanner.Look at Jay Leno's Garage video.You could scale down the original part and repop a smaller part in abs then make a mold off that.Just make sure the manufacturer works with you on this.They may want to collaborate with you to get a new mold in the works.

We don't have the bucks for that nor a crushing need to go linear.

Light-weight

That linear servo converter is the EMS/Jomar conversion kit, designed to fit the Futaba S148 full size servo.

It's a great gadget, but it's only of use for bigger boats that can accept full size servos.

If you want a very small linear servo, look at these by Spektrum $19.99-

These are only 1.5 grams of weight and are used on the lightest aircraft(Mosquito) but you may be able to upscale it's size.It looks like a relatively simple design,maybe use a larger motor and mold a larger sliding shaft and carriage.You may be able to use the same chipboard.It is a very cool design.This may be a job for a super bubblehead!

take a look at this simple micro linear actuator used in a micro AUV http://www.huv.com/nanoSeeker/

with no potentiometer that set up will never match stick position. You would definately be flying by the seat of your pants, not to mention the systems posible reaction time.

I agree with Kevin on both points. Looks like the push-rods are only good for 'bang-bang' throws. Just what are the specifics on that little vehicle anyway?

Looks like an old mobile evasion device innards.

He could be using encoders instead of pots for feedback. Or a hall sensor/magnetic induced feedback.

It's 6 inches long 1.25" in dia.
