OK, first, all three engines power the same spur gear on the trans. The reciever is located on a plate between the fwd body posts. The fuel tanks are mounted on a shelf about 1" above the chassis with all of the wiring between 2 steering servos ( one on each side). This truck has broken about every part you can think of, even stuff it shouldn't break. It has a ton of power (8HP) and yes it does run. With steel CVDs and driveshafts, full metal trans and racing gears with rear spool it is at the point where I can actually drive it for more than a few minutes.

I start it with 3 pull starts, working on 3 roto-starts right now.

t-maxx homie 369

i love it what motors are they do u suffer from over heating with them soo close together [X(]

mad scientist

Actually as you can imagine, HP is not a problem so I run them a little rich and they don't overheat. Tuning wasn't really a problem, I just broke them in 1 at a time and set the idles separately. The hardest part was making all 3 throttles work together. Aside of that on all of the initial part breakage it was a fun project. Thanks!

could you show us some pic of the custom parts you made and could you get some close up pic of the 3 engine where the clutch bells are meshing with the main gear

thebigreddragon

did u break in the engines like that or did u do them 1 by 1?

wakbrdr

he did them one by one

mad scientist

Yes I did them 1 at a time. I have new pics and a short video if I can download it. This week I installed RPM A arms, aluminum bulkheads, diff cases and chassis braces to help with parts breakage. I can actiually drive it around on one engine, but it is not that fast because of the gearing.

that's sick bro

i've got to see a vid. on that truck

That is freakin cool

Sweet truck dude, are all the throttle servos connected together??

mad scientist

Yes all 3 throttles are linked together. An airplane guy at my local hobby shop showed me these adapters that you can plug all 4 servos into (3 throttle and 1 brake) and they all plug into the reciever together. When I hit the gas all 4 work together and because of the slide rod on each engine I can adjust each engine. At first I was going to do progressive throttles but that was boring, full throttle launches on 8 HP are much more fun.

could i see some pic of the custom parts that you made well actualy the motor mounts and what kinda spur do you have in there and can you take some close up shots of that as well plz

mad scientist

So you guys want me to give up all my secrets? I will post pics of the mount and parts soon. This week I installed aluminum diff cases, bulkheads and chassis braces, and it seems to work better. New pics soon!
