hi all im new here.i have got the mini z bug bad.a neighbor of mine has a small club of guys that race and asked me to join so i did.i bought a new mr03 porsche 962 and am curious about whats the most powerful motor i can run in it with the stock electronics.i currently have a pn bb50 turn in there but want a little more speed.we race on a rcp track with diffrent layout each week.will a pn 43 turn be much faster and will it kill the run time much faster?the club rules are the most you can spend on a motor is 20 bucks.thanks

Hi hanker,

On my 03, I've run only the 50T with the stock FETS. I know some of the guys here have run lower turn motors without a FET stack upgrade, but you must gear it properly!! Anytime you run a lower turn motor, run times will suffer a bit as with anything that makes more power.

If I were you and this is your first Z, I wouldn't upgrade it so fast yet if you're keeping mostly stock parts on it. If you've outgrown it and want more speed than you can handle, check out some of the setups that the pro drivers here use and use that as your baseline, but keep in mind each driver has their preferences in handling characteristics.

Mod motors don't always make the fastest lap times if you can't handle the car. You'd be surprised what a PN 70 turn stock motor can do along with the 50 turn motors in the hands of a good driver. Consistency is what will win you races, not brute speed. You don't want to be the guy who drag races off the line to the first corner and cause a pile up because you couldn't slow the car down enough and spin unless of course you run on a huge layout with little tech sections.

I have to chime in here too. We have a recent driver who is running an MR-03 with JUST bearings. He is still running the Kyosho stock motor and placed 39th in the HFAY field for race #2. Within our club he came in 3rd place with 1st and 2nd running the PN 70t.

I would advise on staying away from the 50t motor at first. I'm 90% confident you will have slower laps with it. I'd stick with the stock motor until you have consistant laps (never hitting the walls). Then move to the 70t. Even the 70t is a significant bump.

Welcome to the forums :)

I agree with the others. Unless you race on a huge track, you probably don't need anything more than the 50T you have. If you want more top speed, go to a bigger pinion. What gear combo are you currently running?

To answer your question, yes, a 43T will be faster than the 50T but will have less runtime. It is safe on the stock board. I am currently running an Anima (33T) in my LM car with stock board and its fine.

stick to 70T and welcome to MZR! :D

wow thanks for the replys guys!i guess i should have added that im not a novice to rc driving.i ran 1/10 nitro for years and did fairly well.my driving skills now are on par with the top guys in the club.also i should add that its only when we race the megaoval which is 45 feet long that i want more power.thanks again for the warm welcome to the forum!

NASCAR and a 33 turn!!!!

....or stick with the LM you have and run the oval with an upgraded FET stack.

yea if anyone had told me you could draft a 4 inch long model car i would have laughed!!but ive seen it!!i just wanna be able to pull the draft instead of being pulled.if anyone on the forum lives near me and wanna do some racing let me know we have the club track and a big one (both rcp) in my basement!

oh and to answer the gearing question im running 9/43 with the 50t which i realize is a little steep according to the gearing chart but im running the stock motor pod to keep things simple and cheap.

The 43t doesnt have much more speed than the 50t, but it has more torque to get you out of the corners faster. I typically run the PN 39t in my mod car, geared low. I have also started running the ATM 17mm 40t in my Lemans car, and it is very smooth with good top end. I only have 1 car that has a fet upgrade, and have run the 43t/39t on almost all of my cars, so I dont feel that it needs a fet upgrade, but you do get more out of each motor when you do have upgraded fets.

I have not tried the new PN 33t, but the older one (PNWC handout for 2008) was all RPM and not much torque. I recommend you try the PN 43t or ATM 48t (Stock-BB), as they have good low torque and can be geared up a bit to get the speed you need. They both run very cool and have better runtime than the 39t or 40t motors. I find that on most layouts, the PN43 or ATM48 are all the power that I need. I personally dont like the feel of the PN50t, I prefer motors with Neo magnets which provide more initial torque to get the car out of the corners.

excellent info!im trying to sponge all this up as i know nothing about electric rc as my past was nitro.its a definatly a learning curve but so far about 1/5 the cost as nitro-2/3 less hassles and 100% as fun!!!my car currently has a atomic ceramic diff,ceramic bearings,reflex long king pin front mod,pn 2 way shock,pn t plate and pn 50t motor and countless hours testing.i absolutly love it!last week i put on a #3 t plate and my car was dirt tracking!pulling the inside wheel off the track on corner exit!!!:)

About the most powerful motor:

Don't know the exact specs but the R246 high speed motor for nimh appears to have between 30 and 40 some odd turns. It comes with a 3.5 amp polyswitch. I've never tripped it with 9/44 gearing. Run time is like 15 mins.

So as long as you don't pin the car on a wall and max the throttle, the stock FETs should be fine even with the more powerful tuned motors.

If you're worried about blowing the board you can scavage a polyswitch from an X-speed (same rating as R245 motor) and put it inline with one of the motor leads. There might be a slight performance loss, but it might be worth it to save tens of dollars to replace blown FETs.

One more vote for PN 43t. This motor is immensely torquey, I've undergeared it using the same gearing as you would on a 70t and the car still rockets out of turns. Very fun to drive. Lots of drag brake too so you can slow down quickly turning into slow corners. :)

I like more torque too, but I'm not sure its as important on the type of track described, as compared to a tighter technical one. Wondering if he's not better off with a high winding motor, like a 35T or 33T.

also i should add that its only when we race the megaoval which is 45 feet long that i want more power.
