I have purchased a new MR03 sports. I have just bought the PN racing adjustable motor mount and can't fit my stock motor in it. I have searched for some motors (mainly the PN racing 50t or 70t) on a few sites but they say the motors are not compatible with my MR03S.
So my question is what motor can I buy that will fit my mount and is also compatible with my MR03 sports?

Welcome to the Forums! The PN 70T and 50T should be fine. I was not aware of certain motors not being compatible with the MR-03 Sport.

The way most aftermarket motors connect to aftermarket mounts (from PN and others) is with two screws that go through a plate in the mount and into the front of the motor. The stock motor (and some other Kyosho motors) do not have the threaded holes in the front of the motor to connect to aftermarket mounts, which I think is was you are describing.

I would start with a PN 70T or 50T and then go from there if you need more speed.

thanks for the reply Traveler. I asked the same question on the PN racing site and they said that none of there motors would work on my MR03S unless I upgraded the FETs.
Do I need to do this to put any new motor on a MR03S? I don't race my car so I thought a FET upgrade wasn't necessary. I only bought the motor mount so I can fit different bodys and use the same mount.

Please keep in mind that MR-03S board has only one layer of FETs.
I can not tell you which motors are compatible though. :rolleyes:

If you're just running for the fun of it, a 70turn with an 8 or 9 tooth pinion gear should be more than enough. Just make sure the motor contacts get screwed down properly. Make sure the contact rings aren't touching anything other than the square pads around the holes, and don't let the wire connections cross into each other.

I can confirm that a 70t motor will work with a sports series. We ran one for a couple hours last Saturday without issues.

Thanks for the advice guys! I shall go ahead and purchase a 70t motor and see how it goes. I think I will keep the FET upgrade for a future project. Just out of curiosity is it easy to do a FET upgrade yourself? I have a very basic understanding of electronics and I live in an area where there isn't a good hobby/model store that could do it for me.

You might want to consult with your local computer repair shop. if they are any good at what they do then a basic "fet" job should be a cinch. There are tutorials out there that can provide the basic's.

Best thing I can tell you about your first fet job?... So much can go wrong and only one thing can end up right.

If you a completely surgical about it, and have steady hands and you don't miss tiny details, go for it! But do realize that you may want to have fun with it before you fry it accidentally.

Plenty of info on this site as to how to do the job. I can say from first hand experience though, the newer boards are much more delicate than the old AMs.

Ok I had a look at some of the fet upgrade tutorials and I think its safe to say that is something to be left to the professionals! Thanks for all the advice guys.

If you have a club nearby, maybe they could help you out. Check the Tracks and GTG forum, maybe you'll be closer to a club than you think.

I live in south west france. I have been trying to find a club near me but with no luck. Im pretty new to the whole mini z scene so I think I can put off upgrading fets for a while. A 70t motor will keep me going for the time being.
Im just glad I found this these forums full of helpful advice and people willing to share their knowledge!

Hi!

You can check out the forum MiniZ france. You'll find a club nearby for sure!
And if you come to Belgium one day, let me know! ;)

Thanks for the link Fovea3d. That looks like a much easier solution for upgrading my fets.
However that is a project for the future. At this moment I am about to purchase the atomic 60t motor. Will this be ok in my MR03S? I don't want to buy it and then fry my board!

The Atomic 60T is an excellent motor for all around use. You will be very happy with it. The biggest danger you face is having the car nosed into the boards stalled with the throttle held open. For relative beginners this can be an issue without even realizing it. As you progress and gain skills this will become less of a concern.

As was mentioned before, use extreme caution when hooking up the wires to the board. PN motors use a good grade of wire but the eyelets are quite a bit larger than the stock motors or Atomic motors for that matter. Make sure that when you make the connection you hold the eyelets to the left and right of the screws as you tighten them up. Just insurance really but it's better than learning the hard way. Once you let the smoke out it is hard to put it back.

thanks for the reply but I don't quite understand some of it! 'nosed into the boards stalled' ?
I am new to the whole rc/mini z scene and haven't mastered the language yet!

If you have the car nose first(front of car) into the boards(solid object) don't hold the throttle open. When the rear wheels can't turn because the car can't move it can overload the fets and burn them(let the smoke out).

I try for a long time 70t on my M03s and now I try to momve to 50t but I didn't want to take a risk and i upgrade my M03s with 2 fets of PN racing. Now I have been practicing with the M03s 50t without a problem for 1 month.
