I am looking at getting either a LRP.28, PICCO.28 or maybe a OS.28 but want to stay under 180.00. I am looking for one that would give me the most torque down low. What do you guys think between these 3. If you know of others in that price range let me know. I am not interested in Axial, Xtm, Mach or SH because I already either have or have had them and want something different to put in my hyper st pro or my Caster K8T I have on the way.

Also Would a JP-1 pipe help out too for torque?

I wouls say the picco 28, it has almost 2HP on the dyno stock.

if you're trying to stay under $180.00 then you might want to take off the OS 28, because its like $330 the picco you can get for like $190 or so.

I did not think the OS was that much? Well scratch that![:@]

Yes Picco .28 no doubt. The LRP is a high RPM monster. $180 at towerhobbies with coupon code.

vnmsgt

I forgot to mention the Jammin.28 motors. How do they compare for bottom end?

unluckylonestar

i just ordered a jammin .28 same as the picco p-3 i believe got it for 180 something shipped from amain surpose to be a rocket from what i heard picco got a strong bottom

ericem

The Picco .28 pullstart has different timing. The jammin and picco ,28 truggy motor's are both the same. I am pretty sure they are the same powerwise. If anything the jammin/picco has a better powerband.

vnmsgt

I am going to go with a bumpstart version. BTW why would they put different timing just for a pullstart?

slayerphonics

I have an LRP in my 8ight at it rips,

Unlucky gets his Jammin today for his 8ight, so we will be able to compare the two engines, we will try to post some vids put

LRP from tower is like 178 -25or20 coupon
Picco is about the same little more expensive,

slayerphonics

That would be strange to mill a diffrent sleeve just for the pullstart version

ericem

Doesn't rev as high I heard because they figure people who will use them in a monster truck have to go pullstart and they know a monster truck weighs more then a truggy does.

slayerphonics

I think the revs are diffrent on the pullstart version because of the added drag the pull start adds the crank
Nothing mechanicly diffrent, just a bigger load on the motor.. I could be wrong but that seems to make the most sense

Same thing on the LRP .28 truggy version and pull start version... exactly the same mechanicly but diffrent specs for the revs cause of the pullstart

TheKaiman

I have both the LRP and the Jammin. I have the LRP in my ST-1 and the Jammin in my XT8. You can find both of them for under 200.00 without looking very hard. The RC Shack has the LRP for 160.00. Both are very fast the Jammin has the better low end torque between the two. You can't go wrong with either of them.

JB COMP

the picco 28 pull start has a different crank timing then the bump start picco/jammin/draked 28 the bump start version is supost to be a the "team" version, any the bump start is supost to be better.

How much does it run for a piston and sleeve for these two motors to rebuild? My axial .28 motors are not that bad at about 50-60 bucks. The SH motors I have been using also till they die because I have been to cheap until now to get a better motor are only 35 bucks for them. I run every week almost 2-3 times a week with my truggies and do run some fuel through them and do not want a motor that cost a ton to rebuild compared to a new one. That is why I have been using the SH motors alot.

ericem

I would not be worried about rebuilding the picco .28. They are long lasting motors. BTW rebuilding a motor usually is not worth it anyway, in order to do a proper rebuild you need to replace the bearings, o-rings, rod,p/s. In the end it is usually just better to buy a new motor.

JB COMP

yeah what he said ^^^^^

vnmsgt

That's weird because a lot of people in my area always rebuild there motors and have been fine with just the piston and sleeve. Just rebuilt my SH.28 in my monsoon for 35.00. I have not had a problem with not replacing the bearings so far.

INTEGRA

when a bearing does go tho.....Its a Messy picture.

ericem

Did you inspect your bearings? like role them when the crankshaft was out and check for any play? How many gallons did you replace the Piston and sleeve at anyway? Most people don't think about the bearings, but you would be surprised how it can damage the motor, consider the play in the crankshaft and the extra wear on the crankcase itself and the rod.

You might as well replace them anyway every rebuild they aren't expensive. If you get some nice TKO ceramic bearings (about $22 but WELL worth it) it will actually give you more power and it has been proven on dyno.

vnmsgt

Yes I do inspect them for play and check rod bearing clearance. I am a motorcycle tech and build motors all day long so I know about that stuff and so far I have been lucky. Yes it is good to replace them but you know how technicians are... "if it is there's and not a customers then lets leave it in if it looks good" nobody can complain but myself if it blows LOL!

ericem

Oh thats good, nevermind then your a professional.

vnmsgt

Not saying I am a professional because motorcycle motors and RC motors and not exactly the same, just that I do know about checking stuff like that in a motor. I just like to squeeze every minute out of my motors as possible. Some people run motors for just a season and that is it, I would like my motors to last longer than that even if I have to rebuild them a couple of times.

ericem

You know whats amazing pretty much every motor I owned has lasted atleast 10 gallons!!

vnmsgt

I know 10 gallons is alot but I am almost using a gallon and a half of fuel a month. Just figured I could double that on a motor by rebuilding and by that time I would feel like trying something new that comes out. Maybe I am wrong and its not worth wearing out a motor that much. Think I am going to go for the Jammin .28 motor and try it with a JP-1 pipe and see how it goes.
