OS synonimous to easy to tune, durable, and reliable. it shouldn't give you headaches

If you are new to nitro or RC cars in general you made some decent choices. OS engines are some of the most reliable engines on the market. They are also very user friendly in respect to tuning. Associated is a very reputable brand. Parts for their products are available in at least 90% of the hobby shops in the US and are very reasonably priced when compared to other brands. In my estimation, if it's your first nitro car, you did just fine. Happy racing! Enjoy!!!

i have had one other onroad nitro car but it was an hpi rs4 racer way back when. i worked in a hobby shop and could afford the hobby when i was young but now i have a real job and can afford the hobby just paying normal prices not 40% off. i have been really into offroad and was really good at that but the speed wasnt there and it wasnt as fun driving the cars. i just have not built a car in a while and i am glad that this site is here to tell me whats up!

where are you racing with a .15 engine in your touring car? Good products but the ntc3 is also said to be a 5 min car

Agreed! If you do have failures this is the achillies heel of the NTC3. On my local track last season the #2 fast guy ran this car & when he had failures it was the diff 90% of the time.

when i had my ntc3, i always used a fresh diff for the main otherwise the diff is going to give up on you in the middle of the race, especially if you have a high competition engine and that's why i had 6 set of diffs and keep rebuilding the diffs until finally i gave up and sell the car (i've raced it for about 2 years). tc3 is a fast car but it's pretty delicate and you need to really take care of it. And also get the aluminum front main shaft input, the plastick one is not that strong. Good luck!

Odd , Ive never heard of the .15 RX motor , until now. My guess , its not worth the money. I saw it costed like $200 dollars.

I would cancel the order or return it if you can. What you should get is the os .12 TZ motor , thats os newest motor and its quite frankly very powerful and the same price if not less at some places. Youve definently got a slow motor too cause its saying something like 25,000 rpm. I bet a CV-R can beat that thing out and thats as well a very old motor. The TZ came out last year , costs the same and will have nearly 40,000rpm and double the power. Its the fastest .12 from os, hands down.

As for the tc3 , its an older car. I would have chosen something else for sure. If your on a budget the 2004 r40 can be found for cheap , its a team kit of sorts and has a lot of the option r40 users want. $250 plus shipping.

Otherwise I have a feeling your not going to be happy with either of those. No worries though , things can be returned.

Like everyone says the car not only has diff trouble , but its just plain an older design and granted you paid about as much for a current car and engine , you might as well get something thats worthy for todays racing.

But yeah at least get the TZ , and I would seriously return that tc3 too.

If you like shaft driven why don't you think about the hong nor CD3 kit or pro kit they are cheap and great cars if you don't want to spend big bucks and i would go with the o.s TZ as well.

Hong Nor CD3 PRO+O.S TZ= A great budget combination

I know the NTC3 are great cars but i heard they are a bit fragile and out dated.

O well it's up to you

I think the 15 RX has a red Head on it and if I am not mistaken it is several years old.. it has a black crank case and red ano head.. it came out when the First CV-R 12's came out and this is a big block engine.
