Help identify this nitro model

[Jameson]

Bought this yesterday, I’ve looked everywhere and cannot identifies its male model or origin does anyone know?

 

[marauder]

Looks like HPI bumper, towers, and shocks. I forget the specific model though.

 

[Jameson]

It’s definitely brand new it’s never been ran until today. The low and high speed setting were a mess. It runs strong I need to know what this truck it.

 

[marauder]

HPI Nitro MT2? Maybe?

 

[Jameson]

I tried up upload a video of it running but wouldn’t work. I think your right it’s a hpi nitro MT2, I looked at pics and it resembles that model. Not a bad buy for 50 bucks and thank you.

really don't think that motor is HPI though, with the MT2 it would have been the 3.0, (EDIT: it did come with an 18ss as well) wich is a silver standard type head, the MT1 first run, did have the same type of head, but it was a rotary carb as well, and the steering servo is reversed, the arm is outboard on the MT series from HPI, and the electronic box is more rectangular with a further rearward servo to accommodate a rotary carb not a slide carb as in the picture. and HPI is very frivolous with badging their electronics. it looks so similar though in almost every other aspect.

 

[Jameson]

It’s weird that the motor is new yet very old. It has many differences from MT2 such as the electronics box and steering arm orientation, at least I know what it is kinda though I thank you for helping out. The MT2 makes 11 1/10th rc trucks and 1 nitro boat in my collection. My wife may smash them all to pieces but I love them since I was a child.

wish i could be more help with identification, it seems well built though, it almost seems like a revised MT2, the steering arm in the center would be more protected, and slide carbs are a bit more precise throttle control, and are more options to replace. it looks like it would be a blast to drive! and the center diff with dual brake set up would be plenty of stopping power. its strange to see such a refined truck that has the old style cooling head.

 

[D3MON]

is there no markings on the engine? and or servos?

 

[Jameson]

I agree the question I have is how fast it will go, I notice it has a large primary drive gear similar to the clutch bell, I’m assuming this a centrifugal 2nd clutch device for top end speed. In any event I’ll let you know how it runs today

are you meaning the one in the middle that the clutch bell turns against? if so the technical term is "Center Diff", this is used in place of a transmission on most other vehicles.
what you could do is:
divide the center diff tooth count by the Clutch Bell tooth count,
ex. 52 /18=2.88889
count the ring and pinion in your front/rear diffs and divide the Ring Gear count by the Pinion gear tooth count, to get the drive ratio.
ex. 30/10=3
multiply those together to get the final drive ratio.
ex. 3 x 2.88889= 8.66667
convert your RPM to RPH (revs per hour)
ex. 30,000 x 60 = 1800000
then now, multiply the diameter of the tire by PI then divide by 63360 (inches in a mile)to achieve tire circumference in miles
ex. 4 inch x pi = 12.5663 in
12.5663/63360 = 0.000198333
now divide RPH by final drive, then multiply it by tire circumference.
ex. 1,800,000 / 8.6667 = 207692
207692 x 0.000198333 = 41.1922 MPH
voila
bit of work but would be exactly what you have to calculate the speed, most small block engines are around 30,000-RPM+/-

Guessing it's a redcat or one like it.

thats what i thought first, but the head type throws me off for that, unless someone swapped it out, but that would be a weird engine to opt for. and the electronics boxes/servo mounts are different from what I've ever seen.

Wow that’s impressive. I have not counted any of the gears however I was able to run the truck for a short time today, until the throttle linkage acted up. It’s a fun truck. Once it’s dialed in we’ll see how fast it is.
