I'm using Hitec HS-475hb (76 oz at 6 volts).
(same as I used on the P-61).
I like them because they are very 'cost effective'!
I like using 6 volts: as far as I know, all servos have a higher torque rating at 6 volts.
I'm using HS-605BB super torque (94 oz at 6 volts) on the flaps.
Not sure if this one is still made.
I'll be using a mini on the retracts.
At about 1.5 oz per servo, that save 6 oz on using one servo on the flaps/rudders versus 4 on the flaps and 2 on the rudder.
I think that extra weight in the tail (using 2 servos) is important (much easier to make
a plane tail heavy than vise versa).

As with the P-61, the JR X8103 transmitter will be used.
Power is two OS FX .91 moving MAS 3-blade 14X7 props.
Over powered but easier to move the throttle forward from half throttle than when the
throttle is already at max for when you need more power!
No stats but I think the engine runs better, uses less fuel and lasts longer running her at 3/4 throttle than full bore.
Again, no stats, but it also may be easier on the glow plug
(good to not have a flame out on one engine on a twin).
New engines also seem to burn out a glow very quickly
so I like to replace them after breakin.
Maybe there's pieces of very small metal in there after the turning at the shop that contaminates the glow wire.
No facts on this stuff, just my limited observations.

I noticed that my decal set only has 1 'heavenly body'.
Let me know if yours are the same and I'll contact Andrew/Matt at KMP.
(must be the same manufacturer as the P-61!)
