How is the engine being cooled in the truck?

It's air-cooled. It has an electric cooling fan to improve airflow at low speed, because technically it's a propeller airplane engine that O.S. modified for use in ground vehicles -- but not quite well enough. I eventually moved this engine to a smaller, lighter truck to reduce its workload. This Traxxas Revo was kind of a boat anchor.

Can you please do more bashing or running vids? And also in depth look on how you install it?

I did the same thing about 10 years ago on a T-maxx still have the engine.

Yeah, I've seen T-Maxxes with these engines installed using kits. I decided to use a Revo instead because I already have two T-Maxxes and I wanted something different. If only I'd known how much harder it would be. I'm still working on the exhaust. I cracked two flex-pipes in a row, even after bracing them according to OS. Engines' instructions. The engine runs well though.

@@deusexaethera I didn't have a kit. Back then I don't think they made them. This was before the T-maxx 2.5 or 3.3. My T-maxx came with the Trx Pro .15. I had to look it up. It was over 18 years ago lol. It was great seeing you do this I wish you the best of luck and hope to see more of your video's

Where did you got the exhaust ?

The flex pipe is made by OS Engines, but it's not very good and it cracks easily. It's better to buy some copper tube, cut threads into the ends, and bend it into the shape you need.

I’m looking at buying a revo again soon. Do they make parts to make this a bolt on swap? What’s all involved?

It's nowhere near bolt-on. The engine has long since been discontinued, I had to have the end of the crankshaft machined-down to fit a standard 7mm flywheel collet, and I had to make a motor mount from scratch using aluminum plate and standoff posts.

Hi Shawn! I am working out the bugs after having dropped one of these motors into my Savage XL. What carb is that? Also, did you add a cooling fan? Thanks!

I'm using a HPI T3.0 carburetor. The G3.0 carburetor is also a good option if you need a sliding carb instead of a spiral carb. I did add a cooling fan -- a little 5V blower-style fan. They move more air at any given size than radial (propeller-style) fans do. However, I ended up putting this engine in a HPI Bullet 3.0 after I made this video, because the FS-40S-CX doesn't make enough horsepower to haul a Revo through the grass without overheating. It makes tons of of torque -- more than enough to destroy a 1/8-scale clutch if you're not careful -- but because it revs so low compared to a 2-stroke engine, it has to be geared so high that all the extra torque disappears. I suspect you will have the same problem with your Savage XL, which is even bigger and heavier than a Revo. Here's my current build: www.rctech.net/forum/nitro-off-road/1093014-build-complete-hpi-bullet-mt-4-stroke.html

@@deusexaethera Thank you! I've been on the hunt for a better carb. Agree the savage is heavy however the 3spd helps get some speed out of it and I can still run a 17t clutch bell for low-end torque and it seems to be working pretty well. Do you get a lot of oil spray from the front bearing? There's a lot from this particular motor and not sure why. I am running it rich to help with break-in but wow, it's making a mess and it's a little weird to see so much considering the crank case doesn't have fuel flowing through it like a 2 stroke. Would love to hear if this is something you've dealt with.
