You know this kind of attitude from the Warbird guys always confuses me, it sort of fits with the "you can't put that big an engine in it, it won't fly scale)... to which I respond "can't you take advantage of the fact that the left side (mode 2) stick on the tx also moves forward and back as well as side to side?????

Okay, tirade over.....

IF the OP is going to be playing with larger models, the bigger servos are only a few dollars more than the mid size servos and he can put 'em in anything he want's down the road. Buying a mid torque range servo that isn't any good for the next model is "wasting your $$$" if you ask me.

This is also a place for genuine A123 batteries; 30C continous output and they can burst to 60C. That is a WHOLE bunch more than an LiFe and if you get the genuine article A123, you don't usually have any QA issues found with the copycat LiFe batteries. Places like Andy mentioned are really good sources for A123's and the FMA chargers which have been the leader in maintaining the A123 technology since it came out.

The other question for the OP is what kind of radio gear? If it's Spektrum/JR DSM2 or DSMX, the big PowerSafe rx's are ideal for this kind of application. If it's a big Futaba then Smart-Fly has just come out with a nifty device that plugs into the end of the 6014 rx and allows you to input power from larger size wires like the PowerSafes.

Here's a picture of my 1/5 scale Mustang fuselage equipment. The two 1100mah A123's are the black objects at the bottom of the picture on either side of the fuel tank for balance purposes and you can see the JR DSM2 12 channel PowerSafe rx at the rear of the air tanks. Oh, it's got Hitec 7955's all way 'round just like the Comp-Arf in my avatar....
