My new top speed vehicle!
 

Time for a good laugh...

Ok, I have had this Tamiya M03 chassis for a while. It started life as the Suzuki Swift kit, and I built it stock the first time, complete with the tamiya esc and silver can motor. Later it got a 17t motor and a full bull bearing treatment. Since then it has just sat around, and I played with it often enough to ruin the body.

So I decided to go brushless, had a ahcker b40 12t motor and a sidewinder hanging around. Put them in with the largest pinion, 21t, that will fit. Using a pair of 2100 3s lipos in parallel to power it. So far it has done 42mph, and has a bit more to go, just need more space. This thing is front wheel drive, and will spin the tires all the way to full speed.

This is most likely the strongest rc vehicle ever made. We have jumped this car, smashed it into numberous parked cars, and even played with it with 1/8 buggies. Nothing has broken, worn much or stripped out. Still using the stock gears and diff. I added some turnbuckles for the steering, but it still has the friction shocks!

Anyway, plan is to get it past 50mph, and then maybe put a faster motor in there. I am going to try 4s lipo with the hacker and see what that does. I also have a 7s and 8s feigao 380c motors to try. The 8s on 3s lipo should be fast, it is 4900kv.

Stick a NEU 2215 in there....lol. Cool deal man....in all seriousness a VXL motor would fly in that sucker. Its a solid 70+mph motor and at 3500KV 4S really makes it shine.

I have a vxl motor, but the hacker is the same kv. Only problem with this vehicle is that I have the gearing maxed out right now. I was going to run the 4900kv motor I have on 3s and see how it does. I have a pair of 2200 airthunder 2s packs so I can do 4s.

Is the gearing maxed out because of the spur/pinion options or combined diameter? Don't know what kind of pitch that Tamiya uses, but I just replaced the stock Mod 0.4 pitch gears with 48p gears on my Evo III. There seems to be a very large selection of spurs and pinions with that pitch, and the switchover required no mods at all.

I like your 2p deans connector. Nice and transferable. Is that hot glue for insulation I see on it? Sounds like one tough little machine.

Something different I guess

The M03 chassis has fixed mounts for the motor. It has 3 different sets of holes, for 16,18 and 20t pinion, but using 17,19,and 21t pinions yeilds a much nicer mesh. Tamiya use 48p metric pinions, and the 21t is largest that will fit. You must have a sliding adjustable motor mount on your evo, I have a dark impact that I swapped over to use a traxxas slipper (peg style) and 48p pinions and spurs.

You can get the same connector on tower hobbies from great planes, they have all kinds of deands connectors and adapters. I just made this one. Soldered the 3 deans together and then coated it in epoxy.

It certainly is different. And fun to drive!

I used to have the 4WD version of that! Bought it broken and gave it away in the same condition when I sold off my Stampede and Sledgehammer. I agree - thats a heavy duty chunk of plastic. May end up being a good choice for what you are doing!

A little update
 

I was jumping the car off a home made ramp in my parking lot at work, had a blast, but I ended the day with a broken diff?! Turns out that I had jus stripped a wheel and the hex!

Since I thought I had destroyed the diff, I decided to revamp the vehicle and test some of my newly acquired used electronics. So out came the hacker/sidewinder, and in went a Novak GTB/3.5r combo. Still using the topped-out gearing, but switched to an orion 3200 2s lipo, as it fits the stock tray. I think it is doing at least 50 mph, and I need to readjust the front to closer to neg for better high speed stability. Nice to find that the original diff and drive avles are still going strong, they have hours and hours or time on them now.

How big was the ramp you were jumping?

a group of us put these things through hell every monday night (when its not raining) at suncorp stadium :D

novak 3.5, 5.5, mamba max 5700 on 3s, 5 turn brushed motors, anything we feel like.

cvd's, shocks and ball diffs are the only upgrades worth doing.

fun listening to the scream around! very noisy creatures!

ryan :)

I was using a home made ram, made out of a street sign and a 10inch wide piece of wood. So the ramp was maybe 8 inches high and had a foot or so of face length. Perfect for these little cars.

Video Time!
 

My first vid here on the Monster Forums!

Mine is the yellow swift body, the little green one (yoda) is my buddy's m03.

Good. Glad you finally got someone to shoot for you. Now, you have to get a batter camera and film all of your cars in a huge compilation! That would be the best-est.

That's pretty slick. Tamiya has always made some pretty stout cars. I remember back in the eighties when I was a kid and several of my neighbors had hornets we would ram the into the wall over and over just because we could. Nothing hardly ever broke, I can only remember maybe one or two broken bumpers.

It looks like a fun little project.
