Default Which .12 is better?

Hi all,

Im planning on buying a .12 motor for a little rigger. I am looking at a HPI Nitro Star 12R SS or the OS Max .12CV-R. Both have limited 2yr warranty , both weight 200g, both have rotary carb and threaded crank shaft and both are at LHS. OS is $25 more, so which would be the better more reliable engine? Please Help in this decision.


Thanks Paul

Proubly the O.S one,But I would go with the one that puts out more power! Like high top end rpms and hp too.

Well the OS claims 1hp and the HPI claims more than 1hp it doesnt say how much more just more. They both claim about the same rpms 35-36k.

I've got one of the discontinued OS engines and it's been a good one for me. Mine is slightly modded though with a Nova Rossi .21 carb adapted to it.
I can't comment on the Nitro Star though as I haven't seen one in action. There are faster ones but they cost some serious money. I'm not ready yet to dump $400.00 into a .12 engine yet.

Before I dump 400 dollars into a nitro motor,It better have 3-3.5 hp and screems at top end at 40.000 or higher,for me to drop that big of wad of money!

Have you been over to the Rossi/Axe site lately? They've got an $800.00 .21 over there![X(] It does come with 2 glow plugs and 3 different headers though, none that you could use in a boat anyway.

hp figures are pretty much worthless.... maybe within the same manufacturer you could use them to determine what would be better suited to your application. between manufacturers is worthless.

www.rossisales.com imports the nove rossi marine engines. rossi and nova rossi are not the same.

I would go for the .12TZ from O.S.
http://www2.towerhobbies.com/cgi-bin...?&I=LXJFY6&P=7

According to your selections I would go for the O.S. rather than the HPI. You just can't beat the quality and reputation O.S. Engines have!

Why not drop in an os 18 tz? It should drop in and will give a bit more torque for a bigger prop. The price is not so bad either. A tztx 18 which has the pull start, rotary carb and standard shaft will run you $160 plus shipping at towerhobbies.

Just a thought.

In staying with a .12, if he decides to he can legally run in the IMPBA "A" hydro class. This is why my monos and 'riggers have only .12's in them in hopes that someday there will be a site nearby that will hold an "A" class race.

Right now there is a A class riggers but the problem is alot of clubs dont have enough of them to race. My hopes are to get enough of them together to have a race If not for points or however they do that just for bragging rights

They were going to offer the class at the Indy Hydro Masters race this year but dropped it shortly after announcing it, a big disappointmentas there were enough racers to fill the class and those people wanted to show what they could do and how much fun they are for the price.
The same for my .12 monos. I have 3 of them now but only 2 in running condition.
