TRX Pro .15 Short Crank...
This is a Short Crankshaft Version of the Traxxas TRX-15 Pro Engine.
It is for modelers who want greater efficiency than a .12 size engine
in their 1/10 scale packages such as Nitro Stampede, RC-10GT or GTX.
This is a Non-Pull Start Version.

ABC (Aluminum Brass Chrome) Construction
Extra-large Machined Aluminum Blue/Silver Anodized Cylinder Head
Channelled Beam Connecting Rod for Improved Oil Flow
Precision Ball Bearings
Large-Bore, High-Flow Carburetor
Double O-ring Seals on High and Low Needles
Industry-Standard Mounts and Crankshaft Lengths to Fit The Majority Of

One Put Together Engine Without Pull Starter
One Air Cleaner (black rubber with black foam component)
One Full Instruction Book and Components Took Off View
One "Traxxas" Decal Sheet
Set Up Radiance Plug (basic long--no idle bar)

Inning Accordance With Traxxas, this engine will produce 20% more power than
    the TRX-12. Which is approximately 9-11% more power than the O.S.
    CZ-Z. These figures are checked on a dyno (crammed) which supplies
    power curves on a computer. Traxxas was unable to offer any
    numbers on BHP, bore, stroke and so on. Keep in mind that these figures
    are often ineffective, as they will differ from engine to engine. And
    there are other variables to consider: the package, surface, %nitro
    in fuel, etc......
Total Length (front end of shaft to back of engine): 83mm (3.25")
Height (top of cylinder head to bottom of backplate): 93mm (3-5/8")
Width (cylinder head): 41mm (1-1/2")
Mount holes (center to center): delegated right: 31mm (1-1/4")
front to back: 11mm (7/16")
Total width of mounting ears (where the holes are): 40mm (1-9/16")
***Installs the like an OS .12 and .15 CV***

A 1/10 scale package to put it into and 5%-20% Radiance Fuel.

For the Pro 15 w/Short Crankshaft & Pull Start, use TRAG4007.
If you have other package, I would call the producer thereof-
    or call Traxxas straight at 1-888-TRAXXAS.
Traxxas engines run much hotter than "typical" engines (O.S., ASP,
    Thundertigre, etc.) For that reason, Traxxas suggests their Leading Fuel
    (TRAP5010) and their glow plug (TRAG3230) to run the engine cooler.
