I also found this link for small batteries: http://www.atomicworkshop.co.uk/cata...index&cPath=65
Seems like they're selling pretty much the same stuff, but still. It may be usefull for someone.

motor is running

2 x 10mAh (2p)

Prototype of the servo is running fine too...

I know how small that board is and it makes the model look tiny Chris!

Chris,

Your model is looking beautiful! Looks like two cells are the way to go with the small motor. Can you make your controller work with a DT receiver running two cells?

Joe.

Dave, you guys can post results with the c3blc1 here or in a dedicated thread, I don't care. Maybe post first tries here and when it comes to characterization, we start a new thread to keep the information together. There is no extra thread yet.

Joe do you mean 2p or 2s? 2s wouldn't be very suitable in my eyes. The servos/actuators should run on full supply voltage not on BEC. Also a lot more parts would be reqired to handle 2s I think. 2p is of course the same as 1p.

Since the DT rx can handle up to 10V, I assume there is a BEC LDO on it and it will provide 5V to the servos. You could plug a motor this 5V supply, but then would have big losses due to the voltage drop in the LDO. I am not even sure if this is how the DT rx works, but this is not a good option anyway. I'd say get it layed out for 1S xP.

Ok Chris, I see what you are saying. If I can get the power out of one 20 cell, I will go that way as it will be the same weight as the 2 -10mAh cells.

Hi Chris-

The new controller came in today's mail- many thanks!

I will try to test it soon and will post the results here.

Chris-

Just to be sure- the wires connect as in the photo below? I don't want to make a mistake on your very nice work!

Also a couple of photos showing size and approximate weight for those interested.

as I said: red is black and plus is minus

Yes your assignment is correct. And power supply is single cell lipo (3 .. 4.2V)


Fire it up!

Hi Chris,

I will be testing mine with a DT receiver, and I also don't want to mess up the wiring. Is the wire for throttle control connected to the brushless output on the receiver marked Ch1, or should I connect it to the - motor pad which goes right to the FET?

Connect the + and - as shown in Shagrug's photo right? + is red as shown, and black is -?

Joe.

Chris,
can the length of all the wires be changed without affecting the cct? I'd be keen to mount mine on the DT board myself to make a brick. Any probs with RF interference any where?

Joe,
I have mine running but it needs more copper. I've managed to squeeze smoke out of both the motor and the board but they have survived my onslaught so far!
