I haven't seen a top speed for the Baja. What is it stock and what might it be with the 27 cc motor?
Top speed

I was getting between 34 and 38mph stock everything.I have not tested since.Winter is holding back some progress here.
Speed
I have a 29cc stroker motor and jetpro pipe with the 23mm 40 series tires and was clocked on radar at 44 mph. I am still looking to go a little faster.

Can't wait till HPI gets that 18T out!!
I cant wait for that guy to do those matched sets.....lol:hammer: :scooter:
LMAO...Me too :hammer: :scooter: lol
There is a guy on RCU that said he was counting on 60 MPH with some modded engine. Guess he has been sniffing glue, paint, or something!! This kind of rc car is not going to get THERE!! On road cars struggle to get that fast and that is their cup of tea.

I'll kiss someone's butt in the middle of main street if that can be proven. Wrong style of car. All of these "reports" of speeds and most will end up being a radar gun used running left to right or vise versa which is not accurate. Only straight at you or straight away. Then I have seen not a single pic of anyone using a gps which is the MOST accurate of the 2.
Hey I hope it happens but not likely.

I think it may be possible when the matched pinion and spur gear sets are available, but not until then. I don't think a one tooth pinion change is going to do much though.
i agree that one tooth wont make it. but there is more than one way to skin a cat.
put a 18t pinion on, and then drop the drive gear from 20t to 19t with a good modded motor, i can see 55. some are seeing 50 now, without gearing.

Guys 60mph on a car that size is scary...I see the 10th scales do it all the time and even they had a hard time controling it. I'm not saying it impossible but u better be in a really big space with very few if any obstacles, u'll be getting from point A to B faster than u can react to something jumping in ur way...like a tree or light pole base.
I think these will be more controllable at speeds than 1/10 scale, general drag racing type stuff. A fuel altered w/ short wheel base, all over, nice long top fuel, pretty straight lines. Corny huh? Seriously though, Longer wheel base, wider car=more control. jmo
Hey Turtle, have you calculated the gains of the 18T over the 17T??
Me and a mate did it while we were board and traveling in a car, and we got that if it did do 70km it would do about 82km with the 18T
Heres how we figured it, but im most likely wrong
52 teeth on original, 17 on original
52/17 = 3.06
52/18 = 2.89
Difference = 3.05-2.89 = 0.17 delta
70*0.17 = 11.9 gain
New top speed = 70+11.9 = ~82km/h
I guess its a bit more, ~12% increase... but until you make me some plastic/metal matched sets, I think I will wait.

To tell you the truth, what I posted was not what we worked out, we worked out about 3.5km/h difference at 70km/h also
I changed my calcs in the post because it made more sense.
We worked out:
52/17 = 3.06
52/18 = 2.89
Difference = 3.05/2.89 = 1.05 delta
70*1.05 = 73.5 new top speed
But i changed the calcs in the post because they made more sense. Whats the point of a 5% increase??

Nothing if you ask me. If anything because of the small difference I am thinking of trying both the 18 and the 16. The 16 will give 5% more pickup which could be useful on the track but the 18 I don't see th point of such a tiny increase
Doesn't add up to much does it? Well, better than nothing I guess.
