Default NES591 Servos

Hi,

I am planning to install JR NES591 servos on an Seagull Edge 540 60 size model. My question is... are the servos strong enough for this type of model? I have read around and some suggest to add another battery cell to get some extra torque/speed. Is it safe to run the servos and receiver on a 6V supply instead of 4.8V? Would the charger that comes along with the JR X-378 radio set be good enough to charge 5 cells?

Regards,

Tonio

Default RE: NES591 Servos

Hi Again,

one other thing...
I have finally found the manual for the JR X-378 TX however i have noticed that my version of the tx is different from the one shown in the manual. For e.g. the throttle cut switch is on the left hand side instead of the right hand side like in the manual. I think I have the Heli version... Is there an actual difference between the heli/air version or is the software the same and the user can choose between the two modes????

Im confused [&:]

Thanks

Tonio

I don't have any reference on the specs of a 591 servo (perhaps it is an overseas model) but my guess would be that it is a standard servo, and it should work fine in the Seagull Edge. Most of the servos we have available are fine to use a 6 volt system, I can't speak for the 591 for sure, but my guess would be that it would be fine. The stock charger will work ok, but will take longer to charge. The only difference between the air and the heli 378 transmitters is switch positions, the programming is identical between them and both can be used with either model type.

The 591 is sold in Europe and is very popular. It is a ballraced servo and of high torque (5.1kgcm) for a standard servo. Although the official advice of the UK importer is not to use 6volts with most JR servos, many of us run the 591 on 6 volts and have no problems. I have used it happily on aircraft up to Synergy 90 3D size, it will be fine in any 60 engined model.
