.21 or .28 engine?
Well my engine in my buggy has just about had enough so I got on ebay and started looking at engines. I notice most of the 1/8 buggies have a .21 in them. Then in the few others I see the .28. I know its supposed to be a difference in power, but really how much difference can the move from a .21 toa .28 or from a .28 to a .21.My motor is a SH .28, what would I notice on my buggy if I went to a .21? Is there drawbacks or advantages from going from a .28 to a .21? Why do most buggies run on the .21 engine?

Hi Trigger, .21(3.5cc) engines are race legal in buggies where-as the .28(4.6cc) engines are more for the truggy crew.
You'll probably find that the .21 engines are more high reving than the .28 but the larger engine will have more torque and drink more fuel.

+1 Also, especially if you put a good .21 engine like the RB or OS Vspec etc, those .21 motors have the speed of a .21 like they should and they have plenty of torque for the buggy. I would say, a .28 engine on a buggy is overkilling.

Get a decent quality .21 with the proper pipe combo and you will never look back.
The only real advantage to a decent .28 is torque and a buggy simply can not put
this to the ground as effectivly. The reason you see .28 in cheaper RTRs is that
the cheapest way to increase power if your not going to do the required machine
work for flow is to increase displacment.
Once you get past the really cheap engines a decent .21 will have a much better
mid range and top end than a .28. They are also more fuel efficent.
A Werks B5 with a TT2035 pipe set will set you back less than 250.00 and will
kill any of the cheap .28 you will find on FleaBay.
What did you have in mind for a Budget?

Well redcats lifetime warrenty on the engine is they'll replace it with any motor you want they pay half.. So it isnt that bad. I could get a 300 dollar engine and only pay 150.

Not any engine on the market...just one of Redcat's engines...which are low grade engines not worth having anyways,,,
