Which O.S. 21 is best?

[RCDad]

I started thinking today it probably makes more sense to upgrade my truggy than to buy something else. One thing I definitely want is a better steering servo. I'm using a Hitec 645 now but either its bad or something is wrong. The steering does not seem to be binding at all when I remove the linkage. Should I get the Hitec 945 or something else?

Also, I'd like to get a nice O.S. .21 engine for it. Looking at Towers there are many different models. I probably don't need a pull start since I use a starter box at LHR all the time. Which one of these is best? (right now I'm using a Hot Bodies .26).

O.S. .21 RG Buggy (Sport)
O.S. .21 RG (P) Buggy (Sport)
O.S. Max-21 VZ-B V-Spec-T
O.S. .21 VZ-R (P) Rear Exhaust w/20K Slide-Valve Carb
O.S. .21 VZ-R Turbo II w/20K Carb

Well I can't inform you on the motors I can say that my JR 8800T is AWESOME for the steering on my Revo. I imagine it would work very well on the truggy.

I also run that JR8800t in my trug. Pricey but works well. I also have a O.S. Max-21 VZ-B V-Spec-T in my buggy. I think its too much motor for indoors for me.

I think If I were to buy another motor it would be a P5.

Kevin, you point out a great topic there...INDOORS versus outdoors.

[FreeRideFrosty]

That is why I am looking at the RB .23. I think I can gear it down enough to use indoors and still have plenty of top end for outdoors. If not I will run the XTM indoors if I get that as well... I think that any of those .21 are fine for indoor or outdoor...

look at the Nova 3 port. bad ass mill! torres runs one. it may be my next motor.

nova and rb are the only things id buy....vspek is FAST. but dont have a good track history for bearings going bad. they tent to get soft on compression but they run HARD like that still.

[rocco79]

The engine slim is refering to is the novarossi bf21 . Dent guy 92 runs one also. they are a bargain for the power, and reliabilty you get!!!!

I too would only buy novarossi (for a 1/8 or ATM)

[RCDad]

Wow, I've always thought O.S. would be the best as far as tuning, reliability, etc. Are you sure the Novarossi is better?

[slim]

hands DOWN! rb and nova are tops in longevity.

my rb has 6 gallons on it and i have to grunt to turn it over with my finger still.

havent touched the tune on it for 2 months....

[snakebite46]

Novarossi is far better than OS.

[Michowski]

far far better.

[rocco79]

far far far far better. Italian quality

I think I'll get an O.S. engine.

[slim]

whats swaying you away? that 3 port is badazz and will last longer...

[snakebite46]

Heres a good deal on a V-spec

I think I'll get an O.S. engine.

[dentguy92]

my 21BF is bad azz!!!!!!!!!! lots of power never had a easier engine to tune even my OS
I like it more than my P5x alot smother easier to drive

[snakebite46]

I got a BF I'll be putting in the XB8 very soon. After seeing them run, them are in fact some sweet motors for the price.

[Tex]

if your going with OS I'd say get an OSRG, bumpstart version....low $100 range and you'll be able to harness the power better than going V-Spec IMHO. Too fast of a motor may just toss you around on the track, a slower motor will allow you to remain in control of your truggy. Once you get the driving part down then upgrade to a faster motor.

[RCDad]

That's exactly what I was looking at Tex. The VSpec looks good but the price is a little high. I was also thinking of getting some of those (P5?) plugs. Something real hot to get the motor started easily out in the cold track area.

[RCDad]

Anyone know if the O.S. P3 plug will work in the 21 RG engine?
