Notes from our tech department:
This is a Long Crankshaft Version of the Traxxas Pro TRX-15 Engine.
It is for modelers who want higher performance than a .12 size engine
in their 1/10 scale kits such as Nitro Hawk, Buggy and Street.
This Version Comes With a Pull Starter.


ABC (Aluminum Brass Chrome) Construction
Oversized 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 Most


One Assembled Engine With Pull Starter
One Air Cleaner (Black rubber with Black foam element)
One Full Instruction Book and Parts Exploded View
One "Traxxas" Decal Sheet
Installed Glow Plug (standard long--no idle bar)


According to 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 tested on a dyno (loaded) which provides
power curves on a computer. Traxxas was not able to provide any
numbers on BHP, bore, stroke etc. Keep in mind that these figures
are often useless, as they will vary from engine to engine. And
there are other variables to consider - the kit, terrain, %nitro
in fuel, etc.
Overall Length (front end of shaft to back of starter): 92mm (3-5/8")
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): left to right: 31mm (1-1/4")
front to back: 11mm (7/16")
Overall width of mounting ears (where the holes are): 40mm (1-9/16")
***Mounts the same as an O.S. .12 and .15 CV***


A 1/10 scale kit to put it into and 5%-20% Glow Fuel
Appropriate exhaust system


For the Pro 15 with the Short Crankshaft, use TRAG4007.
If you have any other kit, I would call that manufacturer
or call Traxxas directly at 1-888-TRAXXAS.
Traxxas engines run much hotter than "normal" engines (O.S., ASP,
ThunderTigre, etc.). Therefore, Traxxas recommends their Top Fuel
(TRAP5010) and their glow plug (TRAG3230) to run the engine cooler.
