Default .28 or a .21 for a buggy kit

Ok you guys have changed my mind from a ready to run to a kit. I see most RTR do have a .28(im sure for sales) and ROAR legal is .21. Im not concerned with being ROAR race legal im no pro . .... the guys at the local track here dont care so i guess my question is is there a advantage to a .28 - .21 I figure the .28 has more HP (depending on price im sure) but it seems most .21 in the 200-250 have more RPM can somone sort it out for me

i would say go with the .21 so you can race leagally when you ready to race a roar or any other national event. .28 are good for rtr cars and some truggies but most run even .21 in the truggies and buggies good luck will g

A good race .21 will stomp a .28 any day. Unless you buy a high dollar one. Even then in a buggy it is more than you can put down. You will also sacrifice runtime. My advice is definitly get a .21.

Most RTR's come with a .28 because they can make decent power without being too expensive. Any good .21 will make more power than those rtr .28's all day long. The .21 will also get much better run time.

If you actually want to win a race, get the .21. Most of the .21s are more power than you need anyway. I have a .21 OS Speed and until I started running truggy I was buying tires all the time for my buggy. The .21 makes so much power it burns up the tires - even with the engine tuned down. Get a good stock .21 and have fun learning to drive. I really think in this hobby people, myself included, spend money to spend money. Meaning, buying a hi-priced, powerful engine that burns tires and is difficult to drive. You would hate a quality .28 in a buggy. I have raced with people that tried that, and I hate racing with them. They can't drive them and would crash themself and sometimes me with them.

Good luck and have fun.

.21 for buggy & truggy. The only time I run my .28 in my truggy is on a big track where I have room to open it up.

.21 is the best idea. .28 have power just for a buggy too much and the suck alot more gas than a 21. if you get a truggy though get a .28. i recommend a grp or a os v speed

Please remember what i said about not buying a high dollar racing engine until you get more experience. You will just be wasting the power, and you will kill it, until you learn how to set up, clutches, brakes, and learn engine tuning. It will actually make the buggy harder to drive if you don't know how to use the power, and will not last any longer than a good starter engine. plus you will need to buy a heat gun, and get expert help with break in, and you will probably also ruin your starter box. Start out with a good sport .21. you will thank me in the long run

If you don't care about being legal, the Sportwerks .26 V2 is a great engine. I've just got one and I'm VERY impressed with it. (Of course it is in my truggy, not buggy, so it's legal there.) At $129.99 + $11.99 for the "pullstart eliminator backplate) it is about as cheap as a decent engine gets. VERY easy to break in, and VERY easy to tune. I've heard various reports on how long it will last, from 3-4 gallons up to 10+, depending on who the info is coming from... I can't speak to that yet.

If you want to be "class legal" to race in big races, get a .21, there is no other choice. Most local club races at the local tracks will let you get away with a .26, (or .28) but I'd ask at the local track first to be sure.

my 2 cents you being a new driver I would say a cheap .21 and here is the reasons are

1. .26/.28 way to much low end power for a buggy
2. less power = easyer to drive
3. nobody every won a race because they had the fastest car down the strait


and by the way I have been racing for about 6 years and am always trying to take power out of all my motors i have even gone to running 20% nitro and am running a 6mm restrictor and one last thing i run on a track that is very large 180ft strait and my 21 are still to much power most of the time
