R/C Tech Forums - NOVAROSSI Engine thread....

Hello sir, I am just now getting ready to start running my mantra. My Samurai has just been outstanding. I have about 9 gallons of fuel thru the motor and it is giving no sign of letting go. I am very curious to run the mantra though. I seen one run this past weekend and wow it looks strong.

Just curious what you guys are running for glow plugs. I was looking for some C6TGC but seems it was replaced by the cto6 plug. Anyone have experience with this new plug?

Same plug really. I just run the CT06 or CT07 depending on ambient temps.

I use C6TGC plugs in my Legend 28-8 with good performance. No issues whatsoever. 1.5 gallons on the original factory plug and still running like a top.

the CT06 plug has replaced the c6tgc ..... it is a little broader heat range but works very similar to c6tgc

novarossi has tried to make things a little more simply labeled for the rest of the rc world .... lol

o is for offroad

and yes i have been using them for quite a while and they have been great

Legend 25 question.

Would a 2096 and 41021 be a good combo for a Legend 25 or would the 41020 header be better with the 2096 pipe on this engine? This is for my RC8T3.

Ran an 11:30 in truggy today with the rolling at full tilt and it was still blowing lots of smoke. Not too shabby

Hey knowledgeable nova guys. I am breaking in my ultimate m4r and also may try out the nova mantra. Which pipes do u recommend for these 2 motors? After racing for 2 years, i am an open driver and i do travel to tracks such as psycho nitro blast and silverstate. (I love how u barely touch needles from temperature changes on Novas!)

For Mantra i use 2096 pipe and 41021 manifold. Plenty of smooth power from bottom end to top end. I tried the 9901 pipe but didnt like it. Not as smooth controllable power band with 9901. The power came very suddenly at high low/mid range. The running time for the Mantra i find very good. I got 9min 30 second. With my OS speeds i get about 8 min of runtime.

I just went through my nitro buggy cleaning and refreshing it. I have not ran it in about 3 weeks. The engine was broken in on an EBIS and ran great for 2qts. It is an Adam Drake edition novarossi 5port. I was using the hot #5 plug that came with the engine. I replaced the fuel and pressure line and put in the new CTO6 medium plug. I tried to start it and make sure everything is good and the engine will not stay running unless the glow igniter is on. I tried to lean out the engine to see if that was the problem and it is not. Any help with this would be great. I have never had this issue before so not sure where to start. I have tried 2 different #5 plugs and 1 different #6 plug to see if it was the plug also

So you replaced the plug an the pressure line and the problem started. Other plugs you have tried so it seems it must be the pressure line?

The engine draws fuel by suction at idle - there’s virtually it any tank pressure at idle.

Going from a hot plug to a medium plug will mean your mixture is too rich. Which needle(s) did you adjust and how much? I suspect you’re still too rich - that’s the only reason why an engine will die when the glow driver is disconnected if the glow plug is known good/new.

I tried new pressure line to be sure and still same issue. I would lean the LSN needle little by little with no change. I then leaned with big turns. I stopped leaning at about 4turns lean from flush. I tried to lean the HSN needle as well just to try. I leaned the HSN about 2 turns in from flush with now change to it staying running. I have not opened this engine at all other than changing the carb insert and loosening the HSN the adjust the fuel nipple to line ope with the way I routed my fuel line.

I thought about the going from a hot to medium plug so I put a new hot plug in to see if that helped and it don’t not help.
