4 strokin

[commador]

anyone use a 4 stroke? I had thought about mabey putting one in the nt once the .15 goes. Just as something fun to play with. plus Ive been told they sound crazy.

Other than sound they arent really worth it. Money wise and rpm wise I dont think they will get anywhere near a 2-stroke.

So your cars top-speed will go down as your rpm will not be as high. Thats the great thing about high strung 2-strokes , they rev ultra high and the higher you rev the more topspeed you can achieve.

They used to make a car with a 4 stroke but it cost a ton of money. The gearing was way different since the motors don't rev as high but they have a lot more low end torque so they can pull in higher gears. The one that the used to sell did over 60mph and it was a touring/racing road car. Here is a link to the newer bigger motor. It spins to 21000 RPM which is insane for a 4 stroke but some of the 2 strokes will go over near 40,000 RPM so you can see the difference. They used to make a smaller version of this one.

Found the car. Here it is.



Here are the specs.



Super-sleek body...realistic 4-stroke engine sound!


The latest addition to the FW-04 Series of nitro on-roaders boasts a streamlined McLaren GTR body, as well as the major performance upgrade of a 4-stroke engine.

The included engine is the FS26S-CX from O.S. the leader in high- performance R/C power plants. It's patterned after the popular FS-26 4-stroke engine for model airplanes, and delivers an exciting, more authentic sound that heightens the racing experience. Several chassis modifications have been made to accommodate the FS26S-CX, including a different engine mount, flywheel clutch and exhaust system; a belt-driven cooling fan has also been installed to dissipate heat buildup.

Retains many of the FW-04's super features:
Lower CG for more road-hugging capability


Sealed front and rear bulkheads to keep out dust and debris


Longer suspension arms and swing shafts for more stability


Multi-link rear suspension supported by 3 ball links for adjustable rear camber and toe-in

yea, they lack high end horsepower since they only fire every other time the piston hits top dead center, but they can produce massive amounts of torque, and they sounds cool, so if you geared your car to match the engine it would be a torquey ride but i'm happy with my high winding 2strokes firing EVERY time the piston comes up :clap
