Default Revo Extended Chassis...

I am planning on putting a (large) big block into my Revo and I was wondering which extended chassis I should use. I plan to have a pullstart on the engine and I dont want the backplate to be smacking the rear A-Arm (like it would do with a regular length chassis). Which chassis is best (and cheapest)? 3Racing?...

Traxxas will be releasing the 3.3 Revo as you might know. It uses a longer 30mm extended chassis from the front of the tranny forward.

You need quite a bit for the swap:
Chassis
Longer Front DriveShaft
New 3.3 Length Body (or other longer body)
Longer front Steering Linage

Now you can go further, like the new Engine bay brace, new tranny case (so you can use the center diff and rear brake).

I need the extra length in the back though. I need extra space between the engine and the rear A-Arms so the engine's roto/pullstart backplate wont hit the upper right rear one. I am only interested in the chassis for the engine, no other reason.

Lax, none of the extended chassis (3 Racing, Ballistic, or Traxxas) extend the length in the rear.

New Era makes a weird arm to accomodate your problem.

I finally found something!

ORIGINAL: rcdriv

my big block revo w/ big block and 1/8th scale clutch and a roto start! secret, movie the front left arm to the rear to allow for clearance of the roto.
I hope this works! Anyone else try it?

Well... I got out one of my old front right A-Arms and I began to dremel away at it so it would fit into the rear slot without interfearing with the suspension rod. IT WORKS! Now I can run a pullstart .32 Collari in my Revo without it hitting the rear A-Arm! Im so excited [sm=RAINFRO.gif]! About an hour of dremel work gave me this (on left):





So, binaryterror... did I do a good job?

Those a-arms are going to be far weaker.

Contact FANTOM27REVO on this forum and he'll get you set up with a 2" rear extended chassis that will allow for a pull start on a big block.

This thread here shows some pictures: [link=http://www.rcuniverse.com/forum/m_4049067/anchors_4049067/mpage_1/key_fantom27revo/anchor/tm.htm#4049067]http://www.rcuniverse.com/forum/m_4049067/anchors_4049067/mpage_1/key_fantom27revo/anchor/tm.htm#4049067[/link]

There is no way those arms are going to hold up very long to even light use. At least do that to some RPM arms or something, although I doubt they would last either after being weakened that much. A guy that works with me just put a tigerdrive on his RB TM323, and he has no clearance issues using the Traxxas adjustable wheelbase rear arms. That might be something to look into.

A 3 port .32 in a factory length Revo? [X(]

Ok how much is Fantom's conversion?

Honestly the Starter box seems like a cheaper, quicker and easier answer to me...

i use a 3 racing chassie you can if your running a big block you can use a regular .21 buggy header so the pipe will run on the side of truck and mount the exaust to were the the throttle servo is and you will free up the rear. plus you will get more true performance out of the standard .21 header and every screw in the rear will be easy to get to

I am going to take the practical way... I am going to run the Revo with my stock chassis and custom A-Arm and if the A-Arm breaks or it handles poorly or something... then I will consider getting Fantom27Revo's extended chassis kit. I already pmed him with a couple questions. Thanks for your input guys.
