48" Extra 300 EXP

[Only Fine Helis]

I'm running the 5070's in my 48 extra and they work great. I would highly recommend them over the 65's.

Yes, the 65s really don't cut it. Definite blowback with those servos on the 48" EXP series

I'm surprised nobody has chimed in with the Hitec HS5070:

Designed for an (almost) drop in replacement to your HS65's, but with pretty close to double the torque. Perfect for 48" built up 3D airplanes.

You say almost... How much modifying is there?

 

[Only Fine Helis]

I didn't have to do any modification. They dropped right in with no problems.

In fact, I think they are a little more secure than smaller servos because they don't have room to rotate in the servo cutout the way a smaller servo can.

Nice thanks man much appreciated.

The servo is a little bit deeper than the 65's so you may need to fit a riser to the servo rails if the servo won't fit flush. Some airplanes need this, some don't. It's well worth the effort though.

I just ordered my first Extreme Flight 48" Extra 300 with the power combo. What discharge rate do you guys recommend for a 4S battery for this combo? is 70C too much?

If you could get an actual 70C discharge rate that would be awesome...I tend to disbelieve the really high discharge rates...I suspect you are paying more than what you should for that label. 40C is probably more than enough.
On a 48" airframe, I doubt your power combo could pull anything close to 70C anyway.

+1 ^^^

How much flight time are you guys getting out of each battery?
