Default 1/5th scale 4 stroke engine....

Thats right Honda pulled off a way to build an engine small enough to fit our 1/5th scale and 1/4 scale cars...I saw a working model while shopping for a Redmax backpack blower...The shop owner took a weedeater out back and started it up....I said too bad they cant make these for rc cars and the guy says they do so i did some research and this is what I found and its quite interesting to its power and how it operates.Its available in 25cc 35cc and 49cc..I figured Id share.

heres the info

As i have said before; 4-strokes are way behind in power compared to 2-strokes. No use in having 1 or 1,5 hp in a large scale car. Not to talk about the 7.000 rpm, that is 12-13.000 short off the 2-strokes.

Gear it up. 4 stroke will out torque a 2 any day.

You can always gear up. You have to think, current vehicles out there for us are using transmissions that are designed for 2 strokes, so if a company were to design a transmission with 4 strokes in mind, the problem wouldn't really be there as severely as now. Remember when the 4strokes came onto the scene with motocross? Now, 4 strokes are king over the 2 strokes for racing. I'm sure RC will go through that phase SOMETIME, but I doubt it will be anytime soon.

Another sidenote, 4 strokes are starting to become popular with snowmobiles, something I never thought would happen.

this is awesome, perhaps it will drive a 4X4 better than a 2 stroke?

+1. A 4 stroke has power everywhere.

Years ago- probably back in 1997, FORM and RC World worked on a model airplane 4 Stroke conversion. Super trick machine work, but it didn't work that well due to some ignition issues. Sounded killer though.. The idea has it merits however given the torque as it's been mentioned. Remember the FORM Kyosho Super GP-10 4 Stroke car with the 3 speed tranny and belt driven fan? That car made such a great sound as it went through the gears...
