Well yes i have tons of mac, craftsman, and a few others ... flathead it self are not good isnt that why we use hex or Phillips or star tip these days i love my nova enigens.. what screw driver are u useing there braking my tips off or rounding the edges off on the screws i need to change my front bearing lol crappy thanks for the help.. i even headed it up with my heat gun still wont brake loose

Its a issue for sure i took my dremel tool and shave the side of a biger driver and it work for some but by now the screws r gone

snap on that fits properly.

I'm with Dan. I did have the opinion the flat head were junk. Then I got the right size flat head bit and have had 0 issues. Like anything you have to have bit with zero play. Put the wrong size hex driver in a hex screw and see how well it works. Same with flat head.

Get this and strip no more.

I'm a fan of Novarossi Engines, and I do not work at Novarossi World
But Novarossi stopped producing TOP and REX car Engines.
Says on your website

Thanks
I had to drill the heads off then afyer 3 hrs they came out with my fingers

I just noticed that the REX And TOP line are gone, and the Nova line has hardly any engines left at all. :confused: Are they on the last chapter..?

Hopefully not... Hopefully there will be a new 7 port out soon to replace the Mito, too.

There's no need to spend money on a RC company's flat head, a proper fitting driver from Lowes will work just as well. I think I paid $6 for the one I use on my Nova engines.

Here is a hex screw kit... Novarossi .21 Engine Screw Kit (4-bolt)

Something is on the way from novarossi. Kyle McBride shared a photo of a prototype engine on his instagram about a week ago

This picture??

Currently off-road engines on the Novarossi website.
Mito 4
P5XLT 16
Plus21-4BTT/A WC
P5XLT and
Novarossi Elite 5 Off

Yes. So I guess it's just a waiting game for now

Why? Do you realy think a new upcomming engine will outblast all older engines?

All I know is my $130 elite 5 is a beast

maybe, maybe not.
but in the context of this discussion it shows life at the company.

When I entered the 3.5cc nitro model on off-road in 2005
When I had to buy a better engine they suggested a competition engine and brand that I was told at the time was, buy a novarossi engine that last a long time and are very easy to tune and stable at all levels.

But I did not buy a Novarossi (Pure) at the time I found up to a super good price a RB Products Series 7 and they told me that it was excellent engine and it was made at Novarossi.
I bought the RB in 2006 and I still have it today and it is doing reasonably well.
But in that time the engine has been stopped for 3 years.
Since then I have been a fan of Novarossi World

They may not be the most performing on the market, but the engines are very resilient.
Personal opinion...

Hi, I am pretty new to Nitro, I bought a Novarossi Roma .25 for my Losi 8ight-T 4.0 and I got the carb turned so the ballend is in the right spot for the throttle linkage, but i need to adjust the Fuel Inlet Nipple. I know I need to loosen the HSN Housing, but I am not sure what the best tool is to do that, and since its brass I don't want to damage it. Is there a special hex driver that fits over it? Any help is greatly appreciated

big b - its either a 7 or 8mm open end spanner.

The NEW Novarossi

Novarossi, after months of testing, is pleased to present the new high performance 1/8th off-road engine MANTRA! A name you will hardly forget in the days to come.
This engine is a revolution in the Novarossi off-road engine range, proposing for the first time a square stroke (16.42mm x 16.42mm) on the top range motor, plus a 14mm shaft and new piston/cylinder configuration. Thanks to all of this, we were able to get an elastic and linear power feel, and more torque in medium/high rpm, but incredibly with really low fuel consumption.

NOVAROSSI MANTRA, IS THE NEXT LEVEL!


Tech Specs:

Displacement: 3,49 cc
R.P.M. (max power): 36.500 RPM
Bore x stroke: 16,42x16,42 mm
Sleeve: 4 ports
Rear ball bearings: steel
Front ball bearings: steel
Crankshaft: 14 mm - turbo
Carburetor: plastic - 9 mm - slide
Glowplug: Turbo (C6TGC)
Exhaust position: rear
Starting: standard
Weight: 373 g
Fuel type: 25% nitro

Thats no lie! Best bang for your buck engine there is. Runs so good you hate to even call it a value engine.

Thanks I picked up a Craftsman 7mm combination wrench and got the fuel inlet nipple turned and ready to go. I am breaking in the Roma tomorrow, I need to pull the cone washer and install the one that came with my TLR flywheel, or I might go with the Novarossi Buggy Clutch. I bought the Novarossi Clutch last week, I really don't know much about it other than its a 34mm. I am going to try the Novarossi Clutch first, if I can't get it to work I will put the TLR Steel flywheel in until the aluminum one gets here. I bought a Losi 8ight-T RTR, but the RTR motor was locked up, so I got the Roma, and I have almost replaced all the parts with the kit TLR parts, just waiting on the Chassis and a few small things, other than that its had everything replaced with kit parts.

I wonder is this Novarossi answer to the OS Speeds:confused:

what exactly do NovaRossi need to answer? they already have excellent engines that compete with everything out there.

this is just another option aimed primarily at buggies.

[QUOTE=BigInJapan;14964778]
???????????

Can anyone get me a line on two mantras?

Would have been nice if they silicon filled the crank but easily done I guess. Bang for buck Nova's are hard to beat. Apart from 2 x speeds the rest are Nova's. The so called budget P5 with a minimum of work will easily keep up with the Speeds. Gotta love that!

4 port and square stroke..... sounds like the same as the Ielasi Tuned offroad engines.

Well Kyle McBride has been running the new engine which is the Mantra, even if his says prototype on the head and he is very happy with the new engine, plenty of power, sharper off the line and a bigger top end over the mito 4, he won the QLD state title last weekend with the engine, more testing to go but looks and sounds good

Nothing wrong with the long stroke 4 ports, just lagged top end, will 9901-41021 works this time?

Has anyone got the Mantra Engine yet?

Could be. Nova motors are cheap today, and you don't get raped if you know where to buy them. The OS are nice, but expensive af.

Novarossi Direct USA's price is the same as $ 259. Mito 4 and Mantra.
But in Novarossi World is more expensive than Direct USA.
All engines why?

Novarossi is obligated to sell at retail, the other isnt and helps many others get into the hobby. Novarossi direct is a good place to buy.

The difference is the VAT fctor.

Lost pinch quick
 

So I'm breaking in a roma 25 and temps always 200-210 the whole time.i heat cycled the engine 3 times the first tank and one more the first half of 2nd tank.then the rest of 2.d tank 1/4 throttle,3rd tank 1/4-1/2 varying throttle then 4th tank same as 3rd but a little more 1/2 throttle bursts.afterwards I took the glow plug out to check pinch while hot and it's completely gone but still has pinch when cold.running 30/11 byrons with the 6.5mm insert that cane with engine.so I'm wondering if somehow I screwed up the engine or is it ready this quickly.its never been in dirt,concrete only so far.its kinda worrying me as I've broken in tons of engines and haven't had this happen.thanks for any input guys.

Hello Mfavor,

I would suggest that You should not be worried. A completely Broken-in Race Ready 2 stroke R/C engine will not have "Pinch" when it is Hot or even close to Operating Temperature. It will have a "Pinch" while it is on the resting/room temperature..

Cheers.. :)
