How are servos and receiver powered on a glow plane?

[BillLumberg]

How exactly do the servos and receiver get power on a plane with a glow engine? Are they connected to a seperate rechargable battery? Does the glow motor provide power to a battery via some type of alternator (I'm pretty sure that isn't the case). Are their small rechargable/replacable batteries in each servo and the receiver? Thanks. :confused:

There is a rechargable battery, either at 4.8V (4 cell) or 6V (5 cell) plugged into the battery port (or open chanel) on the Reciever.


The power requirements on most 4 servo planes are low, that a standard 4 cell NiCd pack @ 600mAh will power everything for 30-45 minutes

Hope this helps!

Much longer than that under normal circumstances.

Most radios sold for glow operation come with a 4 cell ni-cad pack that plugs into the receiver. You can also use a 5 cell 6 volt pack which will increase the speed of the servo (transition form end point to end point) and the torque. The battery has a connector on it that is shaped just like the plug of a servo and it just plugs into the battery socket on the receiver just like a servo

I have seen an alternator thing advertised for glo engines to keep the battery charged, BTW.

An alternator will use engine power. The result will be less power to the prop, more parts to go bad/less reliable. Let's keep things simple and have more fun! :D

True, an alternator is definetly not your best choice, the normal run time i find tends to be more like 2 hours on a fully
chraged set of batterys.

I prefer a gerbil on a perpetually inclined tread-mill with a blop of peanut butter dangling in front of it...... :D yes, they use a battery to fly. ;)
