My Custom Built Nitro Powered Snowmobile


Alright, well here is my Nitro Snowmobile. I designed and built this. I had acess to my Dad's work's HUUUGGGE machine shop. And a warehouse full of materials at my disposal
It took me a whole year to get everything just right. It has an onboard glowstarter that can be enabled by a flick of a switch, headlights that brighten and dim as the engine accellerates, (stil working on taillights and turn signals) hobby grade shocks in the rear suspension and in the front.
I am hoping to get a front aluminum suspension made next summer and have it attached to the main aluminum chassis and tunnel that I made.
It has a HPI Nitro Star .15 that has been working flawlessly. Easy starts, good running. Just give it a little heat with the heat gun in the winter and pull about 3 times.
I usually use my Futaba 8Fg 2.4 for this RC, because it has 8 (14) channels for all of the accessories, and I don't see the point in buying a whole new 4ch pistol grip radio.

I am just using a standard S3003 servo, and it turns the skis with plenty of power.

The dirve train was the hardest part. I believe I need to add to it orstrenghten it/rebuild it. I am having too much spur gear wobble.

I am using a plain old .15 sized airplane muffler. No room for a pipe.
The airplane muffler provides plenty of power and I routed a tube from the muffler out where a normal snowmobile's tube would go, and it looks sweet and works great It also gives it a differen't sound, which is awesome!
I also wen't with the airplane muffler because it is quieter than a conventional tuned pipe. This way I can run it in my backyard without any noise complaints.

Edit: I realized that I really need to find a rider.

Alex the sled is cool. I think you might need a little weight to get it to really hook up, plus I think it will help in the corners for the slides.

Yes in those videos I did not have my battery packs under te seat.
I am thinking about putting studs in somehow...but I don't want them to just tear the track instead of the ground.

Ehh scratch that idea. Too much stress on everything.
Thanks for your comments!

Fantastic, great effort. Did you start with a toy Snowmobile and make parts to convert it? whatever that looks like great run to run around.
