Can someone recommend the size of the cells in MAH or the size like sub c etc and type of battery like nicad or NMH for the raptor 90 SE using all digital servos and a 601 gyro.

Thanks

Rich

I've been using the 4200mah sub c cells, 4.8v. I used this same set up on my raptor 90 a year ago, and it's still working fine on my raptor 50, though it's a little heavy.

I'm currently running a 4.8v 1700 nicd on my raptor 90 with a 611 and 8311 servos. Its fine for about 3 flights, but then its time for a charge.

I will be switching to lithium this winter.

If I were you, I would stick with NiCD over NIMH. the nicd's have a higher discharge rate, which you will find useful.

Yeah, the NMH's also are more difficult to charge if you're not battery/charging saavy PLUS when a cell fails, the pack fails, so you're out of luck in a serious way. Need to have a receiver with a fail safe to handle that.

Once you get the Nicads going and have been flying a bit, you'll find you want to go Lithium ion---great discharge rate and you can pick the capacity you want up to 4800mah. They require regulators and so on---so that's probably not the first thing to worry about.

Failsafe wont save you if the battery dies

It *can* if your receiver is a failsafe *receiver*. I guess it really depends, but the stylus receiver has a battery fail safe condition where it will pull the throttle down to low throttle if the voltage falls below 4.7 volts. So I guess it depends on how fast the battery fails. If it's instant off, I'm not sure the throttle will get power to shut down. Anyway, that's an added level of failsafe that I was referring to.
