Motors and Batteries
« on: December 15, 2012, 09:22:49 pm »

I'm doing research on my next project a 1/96 US Light Cruiser.  A couple of things came up I would like some help on. I'm planning on using a 12V system with two ESC, turning  55mm props, I have used a Rokraft 120 ESC in the past. Now here's my first question on motors was thinking about a MFA 500 Motor with Gear Reduction 2.5:1 but looking at MFA's web site I saw a PLANETRY (EPICYCLIC) METAL GEARBOX. Don't know anything about these but they look like a better transmitter of the motor for torque. Any one use these or give me any advise.  On by Robbe U-47 I have used two 4500mAh  NiMH  wired in parallel. I thought I read somewhere that batteries in parallel sometimes work against each other, any comments. on the 1/96 CL I'm planning on using Acid Gel battery. So run two smaller wired in parallel or one big guy with a lot of amp hours.
 Any comments welcome
 Thanks  John

Concerning the batteries, you should be OK if you wire in some big diodes to prevent back voltage flow from one to another.

Mfa motors can be a bit noisy. There are other options. A read of the forum will help you decide. John.
