Hi,

Any advice on the best way to do this?

I've seen vids on youtube showing motors being submerged and run for a few minutes, which I don't fancy!

Cheers,

I've never really bothered 'running' motors in, only thing I did (did!) was to take it easy the first run when new, or after putting new brushes in. I don't see what running in gains?

If it is a brand new motor they tend to be pretested and run in.

If the motor has been freshly skimmed with new brushes. I would do the following:

1. Put a pinion on spin the motor by hand until you no longer hear a clicking type sound which is the new brushes. This wears them in slightly. The alternative is to run the motor under no load on about 10% throttle for a few minutes.

2. Once this has been completed and at 10% you see no sparks where the brushes touch the comm. Increase the throttle to 30% and wait for the sparks to disappear.

3. The motor should now be run in.

I cannot say if this is the best way, but it is how I have been doing it for the last 16 years and it has worked well for me so far

Cheers Tom. I ask because I have a brand new motor and the instructions state to run at 3v for 10-15 mins. I think I'll follow your advice and steer clear of the underwater business!

Cheers,
Barry

3 volts for 10-15 minutes is what Mardave recommend with the motor they supply with the v12 kit.

it's much less important now than in the old days when brushes lasted 20 mins
if you have the capaility 10 mins at 5 volts no load if not just run a battery though at low throttle. its more important/useful with low wind motors than it is with high turn 27's ect
