Very interesting , and you're saying this was in a factory sealed engine?

Yes maybe I will just notch it on other side and run it ?

I,m going to return it thanks

Where did u purchase it from?

And just fyi , I have seen thousands of novarossi engines and not once have I seen that , that's what making me question it jackhammer .

Hope it all gets worked out , if not send it in to me and I will make sure it is right for ya

LHS .had the same reaction you did when I told them will swap out though so that's awesome.

Hello,I was wondering if anyone can help me.I was thinking of buying the nova p5xl for my truggy for next season.I was reading the info on the motor and novarossi recommends no more than 25% nitro my question is it safe to use 30% percent byrons or just get 25% byrons also what pipes do you guys recommend the track i race at is pretty big but it is tight and twisty no real long straight,s thank,s Jack

Yes you can run 30% in it just fine and get the 2084 pipe.

Hello
 

I think all novas are shimmed for 30% if it's a newer black case.

Those instructions are a bit old, but not a bad idea to use 25% in my opinion, just about everyone else uses 30%.

No problem whatsoever using 30% fuel (byrons recommended) in all novarossi offroad engines .

Lmk if you want to purchase a p5xlt , I will do my best to make sure u are well informed and happy with your decision .

Happy motorin',
Monty

whats the cheapest nova motor and has the longest parts list?

like p/r/s?
bearings

Question
 

Hi guys,

simple question... I have an old 21-5KT (busted rod/piston/sleeve). Just got a used Plus21-7KT. Can i just simply switch rod/piston/sleeve from Plus21-7KT to 21-5KT?

Thanks,

Your pm answered

Hope that helped,
Monty

Btw , the answer is yes

Even though there are some crankcase porting differences it will work ;)

'Thanks... :)

btw , do you know eduardo coseteng from over there ?

one of my very good customers and a super good guy :)

what is a comparable plug to the recommended CT6 in a P5?
I am dabbling back into nitro after a running electrics and you (and I) can say I am a noob again. I did not have good luck with the recommended Nova plugs when I used to run over 2 years ago...the OD and OS plugs seemed to be much better for me back then.
I run in TX with 50%-80% humidity if that matters.

odonnell 97t or 87t

the newer c6tgc plugs are pretty good , a touch on the cool side and a lil harder to tune but make great power .

let me know if you need anything ;)

OK..school me ;)

How do you know whether to use a Hot or medium plug? are there general nitro rules to live by?

its usually a temperature thing but humidity plays a bit of a factor as well as how hot your fuel is ie. percentages of nitro .

higher temp is supppose to equal to cooler plug (not cold but medium) but high humidity can fill the combustion chamber with unburnable moisture drawn from the air which in my findings it has been found that keeping with a medium hot will help ignite the fuel better as well as keeping with the cooler plug and lowering deck heighth (shimming) .

cooler temps is supposed to equal hotter plug , usually stick with the medium hot and have no issues . 97t fits the bill in most all situations that is why it is highly recommended .

Thank you so much!
BTW, thanks for posting your break-in procedure!
I will be using your heat cycling method on the mill next week!

How do you know which venturi to use in a P5X?
the blue 6.5 is installed so is that the one best suited for the mill?

that's a personal preference for the most part, it depends on driving style, run time needed, performance needed, track size etc.....Monty will elaborate more Im sure.

truck 7 and a half buggy 6 and a half;)

OK thanks and last question. I have the RC8B with this P5X and a dynamite 86HS pipe but the pipe is too short. I need a longer pipe. Would the 9901 be a better fit?

how about the Reedy pipes. They seem longer too but don't know if that would work that great as the 9901 or 86
reedy 2035 or 2039

get a new pipe hanger;)

Sure, I can use a coat hanger to span the gap.....It is WAY short...I know it will work but it just seems so busted and horribly pieced together

Hi Monty,

If you mean "Jody Coseteng" then yes, i know him... consistently running in A-Main in many races here in the Philippines. Customer? did he ordered something? And yes superb guy, very helpful to us.. noobies.. :)

yes thats him and he is more than a customer , a good guy and i stay in close contact with him as much as i can anyway and he has been the customer who has purchased more than 10 others combined ;)

he must have about 20 engines from me if not more :blush:

he loves those toro nero team engines :weird::lol:

truggy , the engine rocks with either 2084ss or 9853ss and 41021 header :D

I am running buggy and prefer a 7inch pipe (I know, that is what she said);)
the 2039 I hear is more of a top end pipe similar to 086 but wondering on the 2035.

9853ss/41021!!!

2035 sucks on nova engines for one and its no coincedence that novarossi pipes work awesome on novarossi engines

good pipes other than novarossi for novarossi

2013 , 086hs dynamite , 053mr dynamite , jp racing 2032 (awesome) , jp-4 or jp-6 , msr/bullit 1005 , the old thunder tiger 2035 pipe works fairly well , there are more but thats what i can think of at the moment

the jp-3 works fairly well but i dont much like the feel of the pipe and nova engines usually dont get great runtime with this pipe ;)

nova +4
 

Giday Guys

I have a nova +4 with 41021man and 9901 pipe
I have trouble starting when hot it is fine starting when its cold.
Real hard to start if i give throttle when trying to start or if pit guy put finger over pipe to try give more fuel.
I find the only way to get started when warm or hot is to trim throttle 3 or 4 clicks and bump start on box 2 or 3 sec at a time for 10 or more times. But this still takes lots of tries to get it going (if flames out in race it pretty much allover as it take forever too get it going again)

If you know what i mean. (i am fairly new to this rc game)

and i am using rb5 plug as cant get nova plugs from LHS.

So can anyone out there able to help me with this problem
P.S would odonnell 97t be better?

cheers thanks in advance.

Dave

How much run time on the motor? Sounds like low compression. 97tplug works great!!

giday
nah pretty new about 2 -3 gallens.. comp is pretty good i think

What temps are you running,might be running to hot I would try the 97T plug first. Im sure Monty will help you out. And what carb insert are you using

6.5 insert and around 100c in temp

You have a air leak somewhere.

some help from a nova guru?(em. houston? )
http://www.rctech.net/forum/offroad-...g-17011-a.html

Hello all...I have a plus 4 with about a gallon and a half on it. I cant seem to find the right spot on it. Its either rich or bonkers power. Im also seeing some wetness around the front bearing. My needle setting are about 1 turn out from flush on the bottom and a lil in from flush on the top. Is my front bearing shot or is my bottom to fat? Have a feeling the bearing is fine and im just running my bottom to fat...anyone have a good baseline?. Thanks

mr Houston can you ''clear'' the topic and solve my/our problem about the 17011 bearing from novarossi. Nova have a new bearing 7x19x6x6.3? or all of the years the nova had the same bearing?because my engine have different bearing from this which i receive
