Default .28 in a buggy?

is this a bad idea?

by just looking at the specs, .28s have more horsepower and RPM when compared to a .21 at similar price.

I dont care about ROAR rules, .21 only rules, or whatever.
it's just for club racing where it's allowed.

any thoughts?

It depends on your track/racing style. personally I would do it.

I have a LRP .28 zspec3 in a mbx5 buggy, its insane, so much power I LOVE it.

sometimes its hard to control though... spins the tires like crazy. and thats only a 180$ motor... I would like to try one of the 400$ .28 motors from caroinasrc, im waiting for this one to break on me or something.

Tire and fuel consumption will be better with a .21. Vehicle Control too.

I didnt necessarily tell him to get one, I just said that they are ridiculously fun to put in a buggy, its nuts.

If hes all hardcore and serious about getting 1st everytime, than maybe a .21 would be better. but if he wants to have fun, do a few laps with some friends, then I would get a .28. maybe not the fastest choice when you wanna get all technical, but the amount of fun .28s bring is totally worth it.

Any good .21 will outrun a .28 and get better fuel econemy to boot.

I raced yesterday and I had to limit my throttle to 50% with my .21 so I could get traction anywhere.

Thumbs up 28 in a buggy

well for club racing and for new drivers to the buggy or truggy class the .28 is a very easy motor to tune and set up even for a novice ,the only downside is run time when compared to a good .21 i am only getting about 7 minutes with a sport axial .28 , my top p5 .21 is getting almost 9 1/2 to 10 minutes less fuel stops in a 30 to 1 hr main is a big difference between 1st and 2nd and so on .btw both motors were modded for better fuel mileage and both have about 3 gallons

don't go .28 man! Even Truggies use .21's (the serious ones anyway).

A standard v-spec should have all the power you need and then some, and still get killer fuel millage.

Default /.28

I tried an .28 engine in my first mbx5 pro spec, it was too much, lose control easily. If you really want to make your buggy have more power, I suggest have it tuned right, modded (perferably EB mods VSPEC), and properly gear ratio. I run 14 tooth clutch bell on a 48 spur, with EB mods vspec its perfect and FAST! smoother throttle action..

I run a .28 with a mbx5 buggy also.

I use a 18T so the bottom end is kind of "boggy" then once it gets going its nuts, it is too much but its awesome, ones you get used to it and nice tires its awesome.

Im sure the clutch springs have a lot to do with it too, but I dont quite understand those yet.
