This is a Short Crankshaft Version of the Traxxas TRX-15 Pro Engine.|
It is for modelers who want higher performance than a .12 size engine
in their 1/10 scale kits such as Nitro Stampede, RC-10GT or GTX.
This is a Non-Pull Start Version.
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 Without 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 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): 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 OS .12 and .15 CV***
A 1/10 scale kit to put it into and 5%-20% Glow Fuel.
For the Pro 15 w/Short Crankshaft & Pull Start, use TRAG4007.
If you have any other kit, I would call the manufacturer thereof-
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.
