micro speed controller for a plastic kit conversion
« on: December 13, 2017, 09:26:10 pm »

hi again..

im looking for a micro speed controller for a 3D printed model I've just started building.. i've got a spare ATction electronics P68a but as its dual motor i would need two, and they take up quite a bit of room.
the recommendation is something called an ER300?? i've never heard of it and apparently neither has google.. any advice would be great..

happy holidays and happy boating

These crop up on eBay under different names and work well. I use them in a few small boats with up to 6 volts nimh. It even has an on/off switch.

If it's a micro boat, that's all you should need. However if you want a bit more voltage and current range then there is this, which is only marginally bigger. Both controllers are forward and reverse.

As long as your motors don’t draw too much current you can run them in parallel off the one P68. I’ve run up to 4 motors off one micro esc in plastic kit conversions.

Done alot of plastic kit conversion . One BIG tip pay attention to the max input voltage . small props need to be turned a high rpm to make the boat move well . This normally means 6v + . Weight is a big problem so a 2c lipo is a life saver but thats 7.2 v to 8.4v so a 5v esc is a big no no . mtronicks do a very nice small esc .

Sorry - I misread the question. P68a weighs 9gm without its case whereas that Chinese affair weighs 2gm. Fill yer boots.
BTW "Bi-Directional" means it runs both ways, hence "for boats and cars".

Customer Reviews:

Got 2 of these for my WPL trucks. Just about the right size and power handling. Only used with the truck off the ground as I fit it in, but seems ok. Off-load it seems too fast at low speed, but once I put it on load the proportional speed handling should be more obvious. LED brightness varies with speed and flashes at the neutral position.

I bought 2 and they look very good - yet to test as I have to change plugs to suit my equipment. Note that the battery and motor plugs mate so I could cut off the power plug and use it to connect to the motor plug.

I purchased two ESC to mount on a small tank chassis and they are perfect, they are able to drive a motor in forward and reverse, there is no brake function but for it's not a problem with a tank chassis. Used with a 0.8A motor on 2S they are barely warm after 15mn. They have a 5V output BEC to power a RC receiver.

is is a very useful ESC for use in small model boats. Good responsive control, and 50% reverse helps prevent disasters with 'platic magic'.
