User operated fan (or other)
 

I'm not convinced my fan on the mmm is coming on when it needs to. The previous unit the fan would come on regularly, my ir gun would read 40-45C through the side. Now i get readings 50C+ but no fan. I know it works cause it spins when the mmm is turned on.

Anyway I did some searching and found the NERS and MERS switchs. I don't have telemetry but I reckon this would be a good accompanyment if you have enough channels in the reciever.

I don't know if these are old hat but thought you might like to know if you didn't and if you did know then could you share your experience. I haven't ordered one yet. :smile:

Seems kinda more money, hassle & wiring than is needed. Just swap out the stock fan for an aftermarket 25mm item, and put an rx plug on the leads = permanently on fan that will lower MMM operating temps throughout the whole run, rather than kick in once its already starting to overheat... :neutral:

Fair comment Neil. I knew of that method but the idea of being in control (and the extra gadgetry) seemed apealling to me. The mers is quite a bit extra wiring and hassle.

btw are they still making red dwarf? I haven't seen it in years.

If all you want is something that can be turned off/on via CH3 of your radio, save a few bucks and recycle one of your old unused servos.

Oh yeh, I completely forgot about that thread BG.:whip: I don't know how you come up with these ideas :great:

My fan does the opposite, ever since i bought my mmm the fan is on constantly, as long as the esc is on the fan is on...

is this a problem?

Madness. Pure madness. :smile:

It is a problem in that it doesn't operate as it should and therefore something is wrong, and may wear faster since it is seeing more usage. But, it's not a problem in that the ESC stays cooler since it is on all the time. Depends on how you look at it.

I like that servo/fan idea, time to fire up the soldering iron.. :mdr:

Redwarf = last series was several years ago, but they made a mini-series that went out on a non-terrestrial chanel & then went pretty much straight to DVD; by all accounts it was rather crap. I might pick up the dvd regardless though; die-hard fan & all that... :yes:
