RE: Axial 28RR
I wouldnt think there all that great just by looking at the crank and p/s on that site. I wouldnt expect a major diffrence between the other axial .28

actualy this new Axial will be a huge step up over the last Axial... this new motor is actualy a true race motor, the last Axial was just a rebadged K4.6............ You cant judge a motor by pics, the port timing is where all the power will come from...

RE: Axial 28RR
Well I just ordered one from Tower... I'm hoping it'll be comparable power-wise to an LRP .28 Spec 3.. If not it's not that big a deal - for the price I got it for including Tower's rebate deal, not to mention the current exchange rate, I could almost definitely resell it, even for a small profit...
Anyway, I'm very interested to hear more about it.. Gonna take at least three weeks to get here....

every company says that every motor they make is a racing motor....you cant judge a moto b pix? alright...if it is a 3 port in the pix then what isit in real life? a 3 port right?!?!?

Look at the right specs, if you look up the .28RR you will see it is a 7 port sleeve, dunno where you get 3 from, the spec 1 .28 is an 8 port.

RE: Axial 28RR
Hey,
Is the carb the same as on the spec 1? I'm think of putting one in my revo and the spec 1 (other axial .28) carb (HSN) would bang into the spur gear with a qoncepts motor mount.

RE: Axial 28RR
I should of said that it wasnt going into a savage. its in my aftshk right now. The carb restricter is at 8.mm and im pulling wheelies(FINNALLY!!!!
) BUTTT!!! when i tried to take off the head, most of the screws started to strip so im goingg to need to find a good tool that can take em out without stripping them so i can put stronger screws in. Also it still having a bit of a problem trying to tune it correctly. when i let my gf start to drive it she kept feeling that the truck(engine) was moving without her tuching the throttle ( ideling to high) so when i adjusted the ilde set screw, it just kept doing it.
After the next day i fired it up and ran it around for a bit (pulling more wheelies) and it started to idle to high again. im not sure what screw i added more fuel to but it was back to norm.
so the point im making is, the engine runs good but im having to adjust the engine a little bit. almost seems like after each tank. I wouldnt say this engine has INSANE power but it does have a good power output. plus i need to toss out the stock pipe, put the LST2's "HT" pipe on it and switch to the bigger restricter or just take it out all together to see what the engine really can do.
But for the price it IS a great engine. (besides the fact i got mine for $112 and no shipping cost) but if you can get this engine for $150 or less then do it. like i said, once i toss out that stock pipe and put the LST 2's pipe on..... im gonna tare some sh*t up[sm=devious.gif]

RE: Axial 28RR
Based on the pics ofthe crank and the sleeve port configuration, (see this link http://www.axialracing.com/details.p...imgID=1&type=2), the RR looks like it has incorporated alot of nice race design cues that are employed in high dollar race engines.
If the timing profile is also a race designed profile, I can see this engine giving a tough competition to other cheap .28ci engines out there (SH, LRP, STS, etc.). As supertib already said, it is mostly in the timing profiles that determines if this engine will be a serious powerhouse.
Seeing that the advertised maximum RPM is 38500, (if indeed this engine can reach 38500 RPM under the load of real world applications), I get the impression that a pipe designed for high RPM applications would be needed to get this engine to run at its maximum potential. To me, that is indicative of agressive port timing profiles; otherwise, this engine would have a max RPM closer to somewhere between 32000 & 35000.

RE: Axial 28RR
Yeah on the subject of idle. for somereason, once i drive around some more with the idle still to high.. it will come back down for a bit.
I know its too rich at idle because if i let the truck set for a second, i can see a slight "mist" of oil on the ground.
I guess my main problem would be knowing what needs to be tuned and when. Ive never had a engine with a 3rd set screw aka mid speed needle. So trying to figure out just what that does between idle/low speed and highspeed is my question. im guessing when the truck boggs before if shifts is into 2nd is what that screw is for...
But aside from that. i just went ahead and got a lst 2 ht pipe off ebay so ill let everyone know how this pipe and the .28 work in combo

RE: Axial 28RR
Well i just got back from doing a bit of bashing. And to simply put it. THOSE TWO WORK GREAT IN COMBO!!!
Im sure there MIGHT/COULD be a better pipe but really for the price of $30(another rc chop shop on ebay) you cant really beat it.
Now my only issue is i keep breaking my thrust bearing on my aftershock. I have no idea why either. The slipper is set a hair over 1 FULL TURN OUT and when i take the slipper apart, all the balls in the bearing fall out.

Im going to get this is soon as a have a bit more cash on hand

you could get something like this for the same money. I have seen them cheaper http://www.dynamiterc.com/Products/D...rodID=DYNP5232

RE: Axial 28RR
According to that website link, that engine is $300! When you say $112, do you mean with a discount? If so, how do you get it?
