Most of the top racers run .21's for just the reasons Ryan stated. The extra power of the .28 ends up giving you power that many times you don't need. Also, the better fuel economy of the .21 is beneficial.

KRCRacer isn't some kid that just bought his first toy last week. He knows what he is doing and proves it all the time.

The majority at our club feel the .28 is overkill for a racing application. They tend to recommend a good race .21 or a mid-level .28 which tends to have about the same production (if not a hair more) as a high-end .21.

I will eventually change the front bearing in it and keep it for a backup motor.
Funny you say that on the front bearing. I ran about a gallon in mine and mine did the same thing. I have a Jammin with an OS Speed and I run a JP3 pipe. I get great run times. It has a lot of power and good low end too. I just got my Speed back from CEO power mods I looking forward to see how it does in Las Vegas at the Silver State.

I guess you found the site Mike. Yet another secret gone. LOL.
I run a 8T and chose a .21 over the .28 for milage over power. Plus as I run the 8ight too was looking to keep extra motor stuff to a min. I ran the O.S. Speed last season and it is more than fast enough and with the ballast pulled out of the tank I can get close to 14 min. per tank, running at 245 or so on 30%. I have heard good things about Go Tech motors and for the price it would be hard to pass on. A good .21 to race with can cost anywhere from 250 to 500 bones. It all comes down to how much you can afford to spend on a motor. The Rossi 5K is a good mill, but a little spendy.

Hey guys I just want to bring up an engine that hasn't been mentioned yet. the Go .25 6port race. It seems that the .21's do make a good racing truggy, but the Go .25 is the perfect middle balance, mileage is very close to a .21 but it will have more torque then even the strongest .21. It is the best of both worlds and is a great choice in truggy. Pipes that work well on this engine is the 053 and 2047.

So many choices in racing now days its great!

I beileve that for truggy you can go up to a .28 for a ROAR event. so that .25 should be right in there. There are indeed many choices for motors these days which is both good and bad.

there is no "best" some tracks a .28 some other tracks a .21 .....seen picco evo 21's dynamite platinums to mugen, o.s. RB to novas all are very good but some may have an advantage in milage but may lag far enough behind not to matter

I like the low end punch of my Ninja 28 with a tsais t32, very nice for short run up jumps. fuel mileage is all about throttle control.
Used to run a GoTech 5 port in same truggy, it was plenty fast but was lacking on short run ups, just my 2cents, Pooldoc

Understand I am just stating facts, I personally think its more of a track consideration than anything else, and the only full race .28 I would consider running is the Ninja/Falcon/GRP/Losi .28, because of great power curves and still pretty good milage.
Answer me this know it alls , if all pros are always faster with .21s, how come this factual evidence proving otherwise exists:
Truhe runs a .28
http://www.losi.com/ProdInfo/Files/8...-challenge.pdf

Rex Rosseti runs a .28
http://www.losi.com/ProdInfo/Files/8IGHT-T-rossetti.pdf
Gary Guest runs a .28 in his CRT, and many Pros as this post proves beyond ANY doubt that some do choose a .28

So....do you think the O.S. .21 VG-P has enough power for a newbie or is that underpowering the 8ight-T?

I'm figuring if I am going to ruin this think fairly quickly learning how everything works, then maybe for the money that would be a great first motor, but I also don't want to be the turtle on the track (nor to I want to rocket my truggy off the track and into a tree because I can't handle the power ).

With an 8T and S7, I would try all aluminum with gold springs.
