Please take a look!
If i wanted to run a brushed/brushless speed 400 motor on a plane weighing around 10-12 oz, how many Nimhd or Nicad cells should i use?
Should I go with nimhd or nicad? What capacity of battery should I use for 15 min flights? Thanks.. |
RE: Please take a look!
Do the right think right now.. get a brushless motor and a speed controller to go with it and invest in lipo batteries. they are lighter give out more power and have a bunch of other advantages which i wont mention right now.... be warned if you're on a budget you might think that all this stuff is expensive but trust me.. buy it now.. even though it seems expensive it will be worth it in the long run. I hope someone else can elaborate on this point here because I don't have all the resources on hand to go into detail.. hopefully someone can help you better than i can.. but for my money.. brushless- and lipos be sure to learn much about them before you go into it though there are some thing you must learn in handling this stuff.

Hi,
I second that.... invest in a brushless motor and ESC, they are maintenance free and much more efficient than brushed motors. Also, Li-Po batteries are the way to go. Expensive, true, but you wont look back... p.s you will need a dedicated charger to charge Li-Po batteries. |

A geared Speed 400 shouldn't be asked to draw more than 8-10A on 2s Lipo (if you have a 7.2v nominal 400, you may get away with 3s Lipo and 8A max). To get 15 minutes at 8A you would need around 2100mAh capacity. |
