Here are a few .15 engines that i have. you decide wich engine you like.
These are all the engines i used. HPI SC .15 (black) the HPI .15FE and the Traxxas .15TRX pro
Look how much larger the exaust ports are on the HPI engines.
The FE is the same size.
The traxxas exaust port is the smallest of the 3
Here you can see how thin the TRX sleve is. i always thought the thicker they are the better they cool.
Here is another angle of the sleve's
Again you can see how thin the TRX .15 is compaired to the HPI
Here are the 3 carbs from all 3 engines
This is the .15 SC carb, as you can see the size of the carb with the calipers.
another shot of the SC carb.
This is the TRX traxxas .15 pro carb.
I dont understand how its bigger. i measure it as VERY close to the same size as the HPI carbs.
Even the inside diamiter is the same.or VERY close
The HPI .15 FE measures the largest of the 3
These are the 2 cranks notice how much larger the ports are on the HPI.
Notice how much larrger the ports are on the HPI crank.
I do however like the rod on the TRX the piston skurt isnt bad. Maybe this information is incorect im only pointing out what i notice. im no engine expert if i claim to be im sorry. i just REALLY injoy these engines and love to show what i see.
