Set-up Advice for XERUN 120A 1S - offroad

[Hail Ming]

Hi Chaps,

I've decided to have a go with a brushless set-up and so I'm after some advice on general starting points for setting up the speedo for off-road 2WD buggy use.

I've got the Hobbywing XERUN 120A 1S speedo and a Speed Passion V2.0 Ultrastock 11.5 motor (3100 kV). It'll be used in a Mad Monkey on a bumpy grass track (Hinckley). What I'm after is a set-up that will give me smooth control in the in-field and good speed on the straights. I'm a pretty consistent driver and my approach tends to be 'less is more' - I'd rather have a slightly slower car that I can gun around rather than an uncontrollable pocket rocket.

With the above in mind, any pointers/set-ups would be appreciated...

Thanks

James

James,

I run mine in my mad monkey with a 6.5 motor. Turn the punch up to full, same with the timing. No drag brake and 100% brake availability. 9% centre point and just keep it smooth on the trigger finger. I also run the slipper done up fully and have had to add inserts to the diff to stop it spinning up.

Have tried running the lower power modes and just don't get on with it. I want the car to accelerate as fast as possible and for me to decide what possible is.

Cheers

Ben

Thanks for the response Ben - but I think I was after settings towards the milder end of the spectrum.

Ok try going for one off the top on motor advance and two from top on punch. There's quite a difference in these settings. Any lower and the throttle response is a little sluggish.

I just picked up one of these.
Am running in my kyosho RT5. I was running it with a hobbywing 4300kv motor and then a Novak ballistic 8.5. With 2s lipos.

In both cases, the speedy shuts down after around 2 mins of running. I'm not sure why. It looks as if it had reached some cut off point - Temp or low voltage? But I haven't even finished a 5 min heat when that happens.

I'm still using the standard settings on the speedy. Have tried running with a different batt pack but with the same result

Oh, currently running without a fan but I don't think that should be a problem?

Ok I'm running a 2s 120Amp in a Durango and using these settings

Punch = Level 2
Motor Timing = 22.5deg i think (one from max)

Punch is fine, smooth but not dull, though might go up one for a bit more. Top end is nice and fast.

For what its worth motor is an HPI 6.5t and cells are 5000 30c

EDIT - Using stock software on v2.1 speedo!?
