Some more quick questions:

1. When attaching the STEARING servo, should I use the rubber grommets? If I don't how does this effect the spacing? From what it looks like the spacing needed for my servo (Hitec) accounts for the grommet to be in place. There is a significant ~1.5mm difference between using the grommet and not using it. Presently I don't have the grommets in place.

2. I read somewhere and it looks like in the pics that the battery configuration is 3 AA batts on the bottom and 2 AA on top. Is this correct? When I config the batteries that way the bottom 3 don't fit in the tray and the 2 up top hit the fuel tank. Anyone have pics of their battery config mounted to the tray?

Sorry if this is already posted somewhere within the 100+ pages but it's really difficult to find the answers quickly.

Thanks,
Puma

you should put the rubber grommet in place. there are different spacer on the plastic tree and you should be able to seat the servo properly with the spacers.

you need to use AAA size battery rather then AA size.

Did anybody's MTX 3 came with an MR-12 Turbo, if so, what's a good replacement plug for it? I use 30% nitro.

I use Hitec servos also. I don't use the rubber grommets, and my servos fit fine. I don't think using the grommets on the steering servo is a good idea anyway. It will produce too much "play" when trying to turn the car and make the steering very unresponsive.

Use a #6 or 7plug if using 30% nitro

They give them to you for a reason. They insulate the servo from vibration which will eventaully kill the servo. Hard mounting the servo will somewhat shorten the life of the servo. How much, I cannot say.

I agree......for the throttle servo. You don't want the steering servo moving around on you. If you can use them on the steering, and like the feel, then go for it, but I personally don't.



HONEYCUTT!!!!!!!!!!!! Glad to see you came back to your senses!!!!!!!!

I used rubber grommets on 1/8 but I didnt use it on my MTX2 when I first got on nitro tourer. Until I have both my first throttle and steering servos died, I put on the rubber grommet there after and they still survive. besides, I didnt use screws to bolt on the throttle servo but with wrap ties and this will also prolong the life of my digital servos.

Is the O.S. 12TR a good choice for a beginner? I heard they are easy to tune and are reliable, yet still competitive. Opinions?

I was recommended the Integy Hippo starter box, anybody have any experience with that starter?

Sorry for newbie questions, i just really want to buy the right stuff and not have to waste time. Thanks.

The OS is a good engine which is torquey, but at the higher rpms, unless you port it, it has a hard time keeping up with the fastest, but for a beginner, I would recommend it over a Novarossi or sirio etc. It is quite easy to tune, but not as easy as something like a CV. If you truly are a beginner, I think an OS TR should be just fine.

I have such starter box and it works very well. You dont need the dual motor version. The single motor works very well already.

the OS TR is a nice motor with good bottom end but lack of top end and it is good for beginner due to its easy tunning.
