Hi Guy's,

I'm new to the darkside having been flying electrics for the past year (Humingbirds (FP and CP) and an Eco 8). I have just bought a used Falcon 50 'ready' to fly. It is currently fitted with the following servo's:-
Pitch JR NES 591
Throttle JR NES 507
Elev. JR NES 507
Roll Futaba FP 148
Tail Futaba S 3003

From what I have read the 507's are now a little old and the 3003 just isn't up to the job. What do you guys think? The heli will be fitted with a DC Futaba Rx and I have a 9c Tx.

If you think I should upgrade any of the servos above I would prefer to go with Futaba 3001's or at a (big) push 9001's. However I have seen the spec's for the GWS S03T range, the S03TXF 2BB has a similar spec on paper to the 9001 with weight of 46g, speed of 0.21 sec/60deg. and torque of 5 kg-cm or 60oz-in and fitted with 2 ball races. There is also a metal geared version but my experience tells me to stay with palstic gears for less slop.

Look forward to recieving your views.

welcome to the darkside,,, it's nice to see you here, haahaa haa we got you now !! you can never leave,,,, now haahaa haa !!

for analog servos,,, 60oz of torque on the cyclic is good (I would think you wouldn't want much less than 60oz on the cyclic), the 0.21 sec speed is not real fast but if your not into quick tight 3D than that's OK too,,, but for the collective if you can I would go for 80oz of torque, 60 would work but 80 would work that much better,,,

or you could upgrade your Falcon to a Raven, with digitals you would have one monster 3Der,,,

for the tail rather analog or digital you do want a very fast servo, and for the throttle a standard is OK for a while,,,


(now take your used servos and buy a cheap ARF 40 size plane to put them in)..

Jim, thanks for the reply. Really can't see me getting into serious 3D just the odd stall turn, roll and loop with the mechanics in a scale body one day, I think........well thats the plan at the moment any way.

Forget the plank idea, spent 25+ years flying them, had a break of 12 years and come back in to the hobby with heli's.

Going to try not to upgrade the Falcon....well to much anyway. My Eco8 is so blinged out that I'm frightened to do much with it in case I bend it!

What Falcon did you buy? What "vintage"? I ask this because there is not any major differences between the more recent Falcon SEV1 and current Falcon SEV2 other then the current unit comes with a stainless steel torque tube drive instead of the wire-in-tube system of the SEV1 and the V2 comes with the Constant Tail Drive to drive the tail rotor in an auto instead of the slipper clutch used in the V1.

On the other hand, there is a world of difference between these and the older Falcon 46 and the Falcon III's. These older units should have been called Hawk 46's rather then Falcons, as they were basically the older 8mm mainshaft Hawks with 600mm wooden mainblades, a 46 motor mount, a gear ratio change and a longer tail boom.

IMHO, for general non-critical sport flying including basic aerobatics and even entry level 3D or scale flying any dependable servo from the Futaba S-148 up would do fine.

Thanks for the info Phil. I am reasonably sure that it is an SEV1 as it has the slipper clutch but it has got a torque tube drive to the tail.

I made my choice of servo's this afternoon and bought Futaba S3010's for cyclic, collective and tail. I will use the exisiting JR 591 on throttle. As I will only be using a rate gyro for now the 3010 is fast enough.

Big problem is that 'she who must be obeyed' wont let me rip it down until Christmas day has gone Sure I will be back with a whole host of questions then.
