RX8 or Mamba Max Pro for 4x4 SC???
#31
I've run both esc's with the Pro 4 4000 and the MMP/4.5 550 combo.
RX8 hits harder down low imo, but only found that out after I started unsoldering the power leads on the esc when I switched to the Pro 4 on the MMP.
But in regards to your situation...put the MMP in SmartSense. Default on timing, iirc 10 degs. Med start power and 100% Forward power. 15T pinion and hang on, if you can't clear a jump like that...your flat out using the wrong tires or your approach is incorrect.

In my experience bl motors make more power everywhere the more you gear them up within reason keeping a close eye on temps. And will run hot when undergeard. I would run in smartsense low timing and gear up. 15 tooth minimum. Motor should run cooler and make plenty of power.

Please le me know how to accomplish this?
Thanks again!

If you do go the pro 4 4600 you can gear it up and still have the amazing punch because its a 4 pole. So you could probably run that motor with a 16 or 17 tooth pinion and still have as much or more torque and a higher top end

I am confused... How do you turn down the timing on the motor, but keep the cheat timing the same? I thought the Cheat timing was the only way to add/take away degress of timing to the motor (other than the 5 basic smart sense options - 0deg, 5deg, 10deg, 15deg, or 20deg).

In the picture you can see those three screws in the back of the end bell. Just loosen them up some and you can turn the end of the motor.

Ok..Help me out here Randy..I have been under the impression that a 550 can motor has 40% to 50% more torque than a comparable 540 can motor..is this right or did I get it wrong? Now are the SC4X motors also 4pole? Right now my RX8 is a no go..so if I want to race this weekend I have to use my MMP..anybody have any gearing suggestions..I'm using a MMP speed controller with a SC4X 5.5 in a Losi SCTE..
However when you compare the 550 Sc4x (2 pole) to the Pro 4 which is 540 (4 pole) that is apples and oranges.
The Pro 4 has a completely different power band and feel than the Sc4x. Both are extremely fast the pro 4 is in my opinion easier to drive for lower lap times.

Almost every sensored motor out including the Novak 4.5 your using has adjustable timing on the motor itself. On the Novak it has 3 screws on the back on the endbell where the sensor port is. You can loosen them and turn the timing up or down. Turning it to the left will increase motor timing and to the right will decrease motor timing.

Yes it will... They are bothe sensored motors. My only sugestion is a repeat of what others have suggested but here it is anyway. Mess around with your timing and gearing. If you can't find what your looking for than change your motor to a 4 pole motor. You will gain your torque and should still be able to achieve you top end with out a problem. You could also borrow a higher turn motor and experement with that to see if it works for you.
2 things about torque and speed. The lower the Turn i.e 4.5 the more speed and less torque. The higher the Turn i.e 17.5 the more torque but less speed.
Same about timing Higher timimg 40° more speed less torque
Lower timing 10° the more torque and less speed.

Just a quick question guys, I just picked up a 2nd hand rx8, The seller was running a tekin 550 motor, should I reset thr esc to factory defauls as I will be running a pro4 2600? Thanks in advabce

Ok, if you're using an Rx8 motor timing has NO effect on motor performance or temps, fyi.
You can factory reset the unit as that "setup" is what most of us use on the Pro 4 save for adding current limiter which you can do without the hotwire

Cool, any tips on how to reset, Thanks for the fast responcse

A little of topic..but..Randy, Why can't I get my hot wire to work with ANY RX8..it works with my RS but as soon as I hook up my RX8 it won't work..and this RX8 is NEW just bought it today..I'm starting to HATE Tekin....just an FYI I NEVER have any issuses with my MMP and the castle link..
