  1. Bashing
Hey Guys,

I am looking into getting a kit to build, either a new buggy or a Truggy. I am still on the fence. However if I do decide to get the truggy I was looking at putting the OS .30 in it. I know OS isn't the best stuff in town, but usually OS is bullet proof and cheaper than most stuff out there. Has anyone used this mill, and if so what do you think? At this point I like the price at $230 and that is about the max I can spend at this point. If there are any other good mills out there for that price, I am all ears. Thanks guys.

I've never personaly used one but one of they guys that came to our new years day bash has one. it was super fast on his savage, with plenty of power. if i had the cash i would get one.
 
unless you get a true MT (non truggy) you won't need the large displacement engine......you want RPMs for racing.....The P5 will last longer than a typical OS mill anyday.....and I am assuming for th elow price this will not be considered in their top shelf category.....I hear good things only about em but they are still new...I'll wait til more people are past the 5-6 gallon mark on them before I throw one in my RCs.....
the RG is a nice entry mill because it holds a tune all day long w/ few issues......the other OS mills I've had were more finicky...not bad but neeeded more futzing w/........the P5 just stays...I've gone 3 days w/o ever needing to tune it....for me that's a record.....just plop it down and go.....I always fine tune em for that day/terrain/track.....I went to 2 different tracks in those 3 days....never even looked at the screwdriver...I'm loving Rossi for now......

Honestly since I do not rae I have been looking at this mill for my LST and a Revo I might get. I think for bashing purposes and in the correct intelligent hands, it is a potent mill. I have read reviews on it and it seems like it will do well in my rig. Granted the P5 is an awesome mill but I have left that for my X5.

Well that is the thing.... I will be bashing more than racing, and the track I race on is small and top speed is not really a factor ,as is being able to recover from the jumps well. If I ended up with the .30 it would probably go into the CRT... but... only based on what I have read and from recomendations from my LHS. I am with Plaid in the fact that as far as RC's go, or anything that is the "Latest and greatest" I generally wait until things have been on the market for a while. I am looking for a mill that is strong enough to bash, but yet good enough to race. The OS is $230 a price I would feel comfortable with. The OS VZ .21 is $300 I would love to have this one, but is just a bit out of my price range. If the .30 is not the mill I should be looking at, can you guys recomend some decent mills in that $230 price range that would, be a: powerful enough, and b:will work for bashing and racing. Thanks guys.

Well in RCCA they tested it in a LST and they said it had loads of torque. If speed was what is wanted then gearing is all that is needed.

So in essence... all you would need to do is change the clutch bell and spur? If you had to choose a mill to put in a 1/8 truggy... .what would you choose, and what size? I am still green when it comes to tuning, and I have had success with the OS mills. I guess that is why I keep coming back. Thanks

Jon you mentioned you wanted to put it into 2 MTs....that's more what that mill was made for IMO.....I'm sure it will be a good mill for MTs...

I'm still leary of the V-spec......too many "oddities" I see more that just kick ass than not but I do see enough bad ones to make me think about getting one (I actually did buy one and never ran it, I returned it for numerous reasons)....the rossi mills are just tanks....I've seen em come in over 300 and guys are still running the hell out of that same engine.....

In the truggy class you have one speed, so over gearing it for top end will make you suck on th ebottom......I found the high revving mills to be the preffered way of choosing for buggies and truggies......now if Fantom could have made ther .27 actually last more than a few gallons that would be my 1st pick hands down...had the low torque and higher displacement but revved harder than a 421b.......

I'll still say the P5....it's been good to me (and mnay others) so far......and I bought this one used....I've run almost 8.5 gallons through it...Slothy said he ran 1.5......it didn't loose mechanical pinch til about 3 or 4th gallon I ran....it's still kicking now......I just did a complete teardown and cleaning...I mic'd the crank and it's showing NO wear after all that fuel.....just like the Hudy steel Universals it just plain lasts......
 
If you are going buggy/truggy I'll vote for a P5 as well. I got a NIB sealed P5 for 225 shipped on ebay. The P5 will out spin the .30 by a lot. I had a Wasp .28 and a Collari B3 in my LSP. With the right pipe/gear combo, the B3 could take off just as fast and have as good of a top speed, and lasted nearly twice as long as the .28 on a tank of fuel.

I got a P5 for my XB8, but gotta wait till spring to get her goin :(

If your going with an MT OS or Collari .30 would be the way to go IMO.
 
Plaid- I was just saying that I want to try it in my LST and Savage.. Or did that go way over my head?
 
Ok... stupid newbie question... Who makes the P5 and what is its displacement? How about tuning? Is it really difficult? Would you recomend this mill to a tuning newbie? Thanks guys.

P5 made by Novarossi, Rossi, TOP and REX. Did I forget someone?

Its a .21 and I think the HP rating is 2.6. Tuning is awesome but breaking this mill is a PITA! Pinch is super tight. I have had to put it on a drill press to help break it in. Took about 1.5 hours on it al the while I was applying ARO through the process.

I still recommend it
 
I have an O.S 30 in my mgt with just about a gallon threw it.Went bashing this past sunday with a couple of my freinds from the LHS.Freind was running his savage with a pico .27 and a three speed.he took me of the line with a 3 car lead and i blew buy him and beat him by at least 4 cars lenghts.
Ratzo give me some props on this so people belive me.Ratzo heard the story today in the shop with the guy i beat.
 
The P5 is Novarossi like jon2 said, which means it is imported from Italy. This means that it is a very high quality engine, its .21 which means its race legal. It is a 5 port, and will spin a LOT more RPMs than the OS .30.

And to add to jons post, I have a new one sitting in my XB8, after putting on the flywheel, I was not able to turn it over. VERY tight, but has huge amounts of power from what I have read.
 
No Jon I wasn't trying to poop on your post...I was just voicing my opinion on the application...for you and most true MT users it is the mill apparently....in a truggy (what he's seriously considering) he's going to want more range on the power band and not be so linear likt eh large mills are...linear but short powerband.....Tom you can break in a P5 w/ the chrome top starter...I did it fairly easily for one....so don't let it sound all intimidating....

Hey Plaid,
I have never broken in a P5 before, only an OS and the 2.5. I don't have a drill press available to help with the break in so I may have to go another route. That and I am sure the P5 costs some big bucks. With the strategy I am employing, the mill is probably going to have to wait bit. What is a chrome top starter? Thanks


Jon, I am bit concerned about how I would break in a motor that tough still being a relatively newbie motor tuner. Would this be a mill that you would recomend to a newbie? Also, just curious as to how you broke in your mill with a drill press?

Thank you for the info on the mill guys!

Some of the P5s are super tight when they are new..I think Jon Chucked his up in a drill press to get it loosened up......as long as it's got lube it's all good.....Tom, have you decided on the truggy then???

"what mayhem, I have one of those?!?!?!?!"
LOL......
I saw the OS .30 run in an MGT this past weekend....HOLY CRAP is all I can say right now.....SUPER torque......and it just raps up a lot quicker than I thought.......still not high RPMs for me to re-think my original stance on it for truggies/buggies.......If you aren't sure about the mill for now, like you said before you'll have plenty of time to decide on one......it'll probably take a few days to do the build and tweak it all.....you could easily stretch that out over a week or two if you do a tiny bit at a time (I know I just start and keep going until it's done).....

Dude, I swear... do I have a hard time making up my mind or what! LOL Thanks for the info on the OS. I will look at what is available today at the lhs as far as mills go and the prices. I probably will wait a bit on the mill unless the price is right. Thanks man.

Tom
 
Hey Plaid I was just confused with your post that was it. We cool!

Godale, I am shopping for the best price right now. and so far nothing promising. I will order tha mill for sure. I was looking at the Racers edge 32 but I will forego that and stick to OS.

Cool, so you are going to get the OS .30? Are you going to go with the pullstart, or non pull? I am looking hard in that direction, but am still on the fence. I just bought the CRT X1 kit and the electronics, so the mill will have to wait a bit. What MT are you going to put the .30 in? Take care.
