Im still new to the hobby... but.. i want an engine that i can depend on.. :D speed and durability...

also.. with the type of engine.. (assuming that i dont lean it that much..) how mny gal of gas.. can i consume.. before it starts to break.. replace.. this.. that.. etc.. (anyone got experience on the engines above?)

dont want to commit an expensive mistake.. :( help pls..


Tnx in advance!

the nova is almost double of what the OS costs.

on a large permanent track, the nova will kill the OS, but on a small track, and with beginner/intermiediate skills the power difference won't be noticed, so go the OS. I JUST NOTICED YOU SAID OS SPEED, just go with the standard OS TZ dude... ;) , you can get 2 OS TZ 3 ports for the price of one speed, or just go the 5 port OS TZ, mad engine ;)

the nova is the motor of choice at the moment for most high end racers on fast flowing high grip/ or large tracks. Sirio is also a great engine, but again, if you race on a small track save the cash, go with the OS.

i'd recommend the novarossi 2630 pipe with the medium or long header. This pipe i found, frees up the engine and gives excellent punch as well as top end.

Go OS. I was in the same situation as you at the beginning of last season. I got the stock OS TZ .12, non speed tuned. Best bang for the buck.

OS TZ!!! It's a rocket out of the box and still user friendly. :D

Tnx guys...

im also.. a bit.. scared.. "speed tuned" as it may be fragile (is this a myth? or for real..) (my friend got a 5 port 12 tz.. i dont know.. but.. it is screwed up.. like hell.. it run well.. but.. after half a gal.. then it got ugly.. - diff story..)

anyways..

12TZ
3-needle 11M rotary carb
Standard 0.128
(2.1 cc) 0.543
(13.8 mm) 0.551
(14 mm) 7.9
(225 g) 1.5 @ 33,500


is it durable?

maintenance tips?

also.. i use.. sidewinder on my rtr.. :D

Fritzd - OS TZ!!! It's a rocket out of the box and still user friendly.

yes.. i have been reading the website also... :p

It's very durable. Mine lasted for 7 months. THe reason why it only lasted for 7 months is because i didnt inspect and replace the conrod. It stil had a tight compression but i broke the piston because the conrod had a lot of play on the crankshaft. From what I think, if you inspect and replace the conrod when neccesary, it can last for more than a year. :D

A few things here bro. First I will agree with everyone in that you should get the TZ by OS. If properly maintained and more importantly ran in properly without EVER running extra lean, you should be able to get 5-6 gallons out of the piston and sleeve...Maybe even more. I would replace the con rod every 1-1.5 gallons. The important thing here is to run in your engine properly (break in). Do the "heat cycling" method. It takes longer to break in the engine, but will last much longer and also be much faster and more reliable. Also do frequent inspection and cleaning of your engine. Check the rod for excessive clearence on the crank and piston end. If it has ANY slop, that is excessive!! Should be replaced before it gets to this point. Use a caliper to measure the clearence.

Next, would be the cost difference between the Nova 12plus3 CT and OS TZ 3 port. A good price for the TZ is about $200 and the Nova is about $300. Just wanted to clear this up as the Nova is not TWICE as much. If you can run the 5 port TZ, I just saw it on sale at Towerhobbies for about $160!!! Just a heads up. Good luck. It is also recommended to use after run oil in your engines after each day of racing. I personally don't, but I think depending on your climate it would be a good idea. Dude, good luck and Keep off the boards. It's different driving on a track. ;)

haow many litres is a gallon of fuel.whaen you say 1-1.5 gallon how is this compared to litres of fuel?

:nod:

It's about 4 liters equals a gallon. So replace rod every 4-6 liters. :)

if he is willing to pay for the plus 12 i would get that much better engine

would you consider a Picco JLR "Red-Dot" for $179?

If you are new to the RC game, I would stick to the OS. brand engine. They are very easy to set and have very good reliability. The poweband is mild and have good RPM. I see many guys at the track who tell me that they have not touched their needles and have seen the tempretures that they run are in the very low 200 range.
Prices for a OS are cheaper than Novarossi.

:nod: :nod: :nod: :nod: :nod:

:nod: you should :nod:

100% its fast and is just as fast as the nova if your tune it right and have the right gearing. :sneaky:

It's about the same power from what I've seen. Novarossi = big price for a name right now. Picco used to have some problems, but no longer.

That's brilliant. The guys says he's a newbie and you recommend one of the fastest engines out there to begin with.

That's an easy way to get people out of the hobby.

Why are you using Burito's avatar. That's confusing! :confused:

i see...thanks.As for the thread,i would recommend the os max for a new user of rc car.this was my first engine as well and i still have it without changing a simple part of it.On the other hand the Novarossi which was my new engine after the os max,is far a better engine,but if you buy that engine as a newbie you won't have in the future any desire to feel sth faster.go for the os,you won't regret it.Moreover the spare parts of the TZ P 3 are much cheaper from Novarossi.It has a lot of tourque and if you gear your car with long teeth set up you'll have top end as well.Be patience and go for a better angine after some months of use with your os max.There are a lot of things that you must learn about tuning,temperatures,plugs,clutch set up etc...it does not worth to try all this new stuff for you on a Novarossi!

stock os12 tz is great motor in bang for your buck. and if your new its only 200$ so if you make some mistake tuning or running to hot etc its only cost you 200$ rather then paying for the nova name ;)

my last motor was a std tz and i ran it on small the medium sized tracks and there was nothing in it between others i was racing against with very expensive donks, so you wont be dissapointed if you choose this motor.

I hate to break the news to everyone, but Novarossi is MORE then a name! You get endless performance, life span and most of all reliability. If the performance is the same accross the board as the cheaper motors, why do some of you own them that are saying this? I agree that the 12-3 is not for a beginner, it's tune is much too delicate. You NEED excperience to tune these engines Great. Not just good...but great. Most racers can tune an engine good, but that number drops quit a bit when you talk about tuning a Nova GREAT. I'm not knocking an inexpensive motor by any means. Especially the OS TZ. Great motor. Sounds as though the JBL Red Dot is also. Not all motors are designed for all tracks either. Small to medium tracks wouldn't need a JP modified for example. But get on a larger track and watch them walk away form the cheaper motors. If your TZ is keeping up with good Nova, then the person driving the Nova needs to work on either his tuning or his driving skill, not his power issues. In fact, lots of racers would actually be faster with a milder engine. Sorry to go off everyone. I'm not trying to upset anyone or point my fingers at anyone at all, here or anywhere for that matter. Not ALWAYS, but usually you get what you pay for. Some engines are more expensive for a reason. Name plays a small part, but those names have also created a reputation and reliability factor and are worth the extra $$. Nova, RB are not more money just because of the name. OK, I'll shut up. Not trying to open a can of worms guys, just making a small point. By the way, I own a few cheapies too. :D I think I'm tired and need to go to bed now. ;)

By the way, I still recommend the TZ as I mentioned earlier. It does ROCK for the price. Later guys and gals. :)

Thank you so much guys! I think ill go with TZ.. Fyi.. ill install it on an underdog.. which is the CEN CT4R.. (i had.. the CT5.. enjoyed it so much.. so ill try the CT4R)


BUT this JUNE... ill get the NOVA for my NT1 (will get it from HK) :sneaky: - But just looking at the design.. and the details of the NT1.. i think im just gonna display it.. heheheheheheh


stefan - tnx for the concern..


this is a great nitro RC community!

Tnx guys!

Well said!

What motor is in there now? And this is on a cen car? I would look into a budget budget motor. Im not sure if getting a fast motor for a newbie would be a good thing or not.

Youll probably go faster with a slower motor. Then once you get the hang of that motor then possibly buy the tz. Id just run what you have now. You put in a tz and go racing your first time , its not going to be good.

I didn't see any nova's or jp's (or any other motor for that matter) "walking away" from the OS Speed 12TZ that won the GLC in Toledo last year. Would you consider this a "larger track"? Hmmm... :weird: :lol:

You said what most of us were thinking anyway! :D

Besides, take a look at what most of our signatures say we run..!

I'd also have to agree with OS engines. They are smooth, reliable, and inexpensive to rebuild. The Speed Tuned is no slouch by any means and is FAST. Regardless I've seen fast guys at my track using a bone stock TZ in whatever car they used to run and it'd keep up with anything. Don't forget to add in the NINJA as it's also a great motor for the price (same as the TZ) and FAST.

I NEVER mentioned Speed Tuned ONCE. I did mention TZ, just not Speed tuned TZ. Plus this does not fall under inexpensive. I can get the 12-3 and LOTS of others engines cheaper then the speed tuned. At least the places I purchase from. I have never seen a OS Speed tune run, only a regular TZ. I would hope it keeps up with the Nova's and JP's since it's in the same price catagory. My guess is that Speed tuned that won in Toledo was not purchaced off the shelf, though I could be wrong. I have heard they are pretty fast though. Plus I'm not familiar with that track, but it sounds like you are. Trust me, I have nothing against OS. I even owned a regular TZ and my airplanes are filled with OS engines. But with my experience, this is NOT the engine I would run at a large track. Maybe the Speed tuned...yes, If I knew more about the Speed Tuned, I might purchase one of those some day. But for now I'm quite happy with my RB's, Novas and JP's and soon IDM's. :D But either way, thank you for the Toledo race update. What car was he racing that OS in? Just curious is all. Later :)

Mugen MTX-4.

Point tanken my friend! I will admit I was a bit tired when I wrote that, so not sure if my point made any sence. A lot of you guys have some killer equipment for sure. No I didn't realize this at first, well maybe not all of you. I suppose that I just think out loud sometimes. You all had great imput on this thread though I will have to admit. Meaning no one was telling dude to go for the $500 dollar Murnan Modifieds and all. Well you get my point. Great job everyone! :)

Thanks bro! ;)

I would still rather buy a Picco IDM or JL Racing engine than anything from novarossi right now. The performance is just as good. Novarossi used to be top of the line, and may yet still be. However, I don't see people running $200 Red Dots having any trouble wooping up on the JP FX motors at some of the races.

i would go with the nova (thats from the choices you have posted)

Here's what you said.

So, that was the only thing I was arguing. A JP full option w/ceramic is close to $500. @nitronation. A OS Speed 12TZ can be bought for around $300 from Hong Kong. I think most people would consider $300 cheaper than $500.

The Toledo track is amazing with great people running the show. Everyone should try to get to the Great Lakes Challange race that they have every year. It's a great time.

Check this out and look at the Ofna/Picco JLR.12 Red-dot. you can purchase ithis motor from Kamikaze Rcing here's the link http://kamikazercracing.com/products.php?cat=4 these motors are fast and reliable and did I mention cheap!

Nice price! Are they easily tuned by a newbie to nitro?
