Help with Change of Motor for my Xb4

[thorny97]

Afternoon Everyone,

I'm looking for some advice please with motor choice. I currently run a Xray Xb4 on astro turf, worksop's rubber/cork floor and dirt.

My current electrics consist of LRP Flo Controller and lrp x12 6.5. I want to keep my flo controller but want a motor which is more smoother to work with on acceleration.

Please can you help with advice on which motor would work best for me.

I have got a dualsky 7.5turn as well, but that seems to lack power against the people who I race with.

Thank you for the help

Im sure you could smoothen out how it puts the power down. I run 5.5t tekin motor with tekin esc. These are known to be very aggressive, but with some expo on the throttle and a mild punch setting its real smooth and easy to drive.

I'd first try playing with settings.

Few things to try;-
Increasing timing on the can should soften the bottom end a little while giving it more top end.
Puch setting on esc (current limit its called on mine)
Exponential throttle curve on transmitter or esc too to soften the bottom end.

I'd be shocked if you cant make it much easier to drive with a combination of setting changes

Thanks for that Danny,

The available settings on the flow are auto brake, brake ramp, brake type, initial drive, torque timing, boost timing, boost angle, and then cut off.

I have got initial drive set at 2% out of 5%

looking at that, I'd say, lower the torque timing right down. drop to minimum on initial drive and dont run any boost to start. Try setting an exponential curve on transmitter too. I run between 25-45% depending on the track. Curve should slope gradually upwards. It varies on transmitters as to whether its - or + expo to achieve it.

If your really set on a motor change, I think the reedy motors are known to put power down soft and smoothly.

Ok, I will lower the torque timing down, I didn't run and boost. I will check my transmitter, (dx3r pro).

Just been reading up on x12 timing inserts, I have standard at the moment, I can go to +5 or +10 for higher rpm or -5, -10??

thanks

A higher timing value on motor should make it put the power down a little softer on bottom end

let me know how it works out for you, it worked for me, expo being the biggest help.

LRP motors are known to have a lot of timing built in. The standard off-road setup for the timing plug is -10, so if you have 0, that explains why you feel too much power.

[thorny97]

So I want a -10 on the motor and not +10. Racing this weekend at broxstowe so
Will try it, thanks

[thorny97]

Checked my timing last night I have -10 (4 dot) on motor 27.5 of timing. I will change it to 2 dot which will be 37.5 of timing for the weekend and see what happens. Thanks for the help
