Mod 1
First grind off the steering stops (not shown) and then use your mad dremel skilz <mds> to notch the arm as shown to get that little extra turning you may need.

Note: I removed the two stock steerig servos and installed one Airtronics 358 instead
Note: Replace the stock steering arm with a longer one.

Mod 2
I relocated the throttle/brake servo and used Associated post to mount it. I cut the bottoms of the post so the servo would set flat.

Note: I replaced the stock servo with a Air 358 here too.

A minor mode to the linkage and everything works sweet. That is a Team Losi servo horn shown.

I removed the box that held the old servo and did away with the reversing servo. I installed a forward only gear kit in the tranny and a close ratio shift kit.

I had to mount the return spring on the roll bar.

Some have removed the roll bar and front & rear bumbers to lighten the Revo... I still crash to much and decided to keep them on.

Birds eye view showing the relocated servo. That is a stock Mugen air filter assembly that I glued onto the Revo extension.

Note: I also installed the P2 rocker assembly, put 55w oil in the shocks and increased the springs to orange and gold.

New starter box from Ballistic Batteries, works sweet. Even works better with the larger Revo flywheel.

Note: Removing the electric start eliminates a ton of weight from the Revo and lets the 2.5 engine sing.

You'll need to hone your Mad Dremel Slilz to complete this mod to install this engine.

First you have to remove the fins from the bottom of the engine case.

The end of the crankshaft needs to be shortened. (Shown here allready cut-off.) A couple of threads need to be removed also.

Test fit your clutch shoes and bell to gauge how much has to be removed.

Here is another pic showing the completed dremel work.

I used a Mugen flywheel nut. I had to dremel the top down to where the threads ended.

Test fit your clutch bell assembly so that it just clears the flywheel.

How custom do you need to get? The throttle arm on the carb is too short to catch the Revo assembly. I used the dremel on a button head bolt made my own.

Note: I used a drop of blue locktite to secure it.

Finished assembly ready for install in the Revo...

almost...

skip this picture

Even with all the grinding and fitting on the crankshaft, the clutch bell teeth still hit the pressure plate on the slipper.

Mad Dremel Skilz fixed the problem.

This is a good picture showing the gear mess now working without binding.

Now that is a custom throttle connection.

Note: you have to move the pivot to the outside hole to avoid binding the throttle.

You'll need a new exhaust header for the motor. I am using the dynamite one and it seems be working fine.

Editors Note: This motor rips in the Revo, with the stock gearing I can pick the front end up at any speed... way too much fun.

In the interest of keeping our revo class fun. Most of us have decided to run the 2.5 during club races... they still put out enough hp to have a blast racing ...

see ya on the track.

I moved the battery pack to the front shock tower trying to keep the front end down while excellerating

If it don't go... Chrome It !!!

Looks like the old moto-x style heads from the 70's

A dab of silicone, some rubber bands and let set over night to cure.

Note: I used a belt sander to smooth and straighten the cuts before glueing.

The completed project...

Clean install :-)

Front toe-out 1 degree.
Rear toe-in 2.5 degree. Use 3 if the back end is too loose.
Camber 1.5 front and rear.
