2300mah enough to run glow driver and rx?

I have 6 Futaba s3004 servos on my twin engine plane, I was going to add a remote glow starter actives with the remote, can I run the glow starter and the rx on one 2300mah pack or will the glow plugs suck to much juice out before I get to fly while starting
Thanks jeff

You have me confused. Are you running a programmable glow driver? Anyway the battery you have should be ok. Voltage on glow plugs is low and drain from what ever glow driver you have should be low

Confusion

You have me confused also.
The glow driver has to be 1.5 volts to force typically 3 amps through its coil.
The receiver needs typically 4.8 to 6.0 volts.

Both canot be fed from the same battery.

I wonder what is your arrangement (setup).

I admit I do not know about "remote glow drivers" else than have a connector permanently on the glow plug and bring two wires to a connector on the side of the fuselage away from the engine and use a regular source of voltage or current to feed the glow plug. One wire is on the glow plug the other to the frame of the engine.

Editing
I went to the McDaniel website and saw the MCD471 on board driver.
It appears to be a site under consruction and no real knowledge is available
I got the McDaniel from the following posting.

The McDaniel remote glow drivers I'm experienced with have its own battery pack. Mute point then!

Many Glow drivers are powered from LiPo or NiXX power packs ....

Here's an example of a 6 - 12V supply Glow Driver from HK :

Recc'd power pack is a 2S liPo.

Here is what I got, the price was right so I thought I would try it. The controller sends full power to the plugs when switched on then after the throttle is moved it will cut the power or apply 50% power when the throttle is below 1/4. It was cheap so I thought I would try it, i just I have no idea what size battery to use here is a link the the eBay posting and a link to the manual

jeff262,

If you noticed in the manual they show a battery voltage of 3.2 - 8.4 but conveniently for them they do not show a battery capacity.

No matter what, the glow plug still needs approximately 1.5 V x 3.0 Amps = 4.5 watts whether being pure DC or pulsed at a higher voltage.

You can figure how long 3.0 amps can be drawn (supplied) by a battery of XXXX mAh.
I would use a separate battery to avoid the risk of loosing control due to a discharged battery feeding the receiver and servos.

On a different line .... in the old days of panels and pumps that I used ... 1980's ... the Glow driver on the panel actually fed 12v to the plug. But pulsed so that it equaled 1.2v ..... in fact we used to patch it to charge up Tx and Rx packs in emergency. The output was basically regulated to whatever it connected to.

The gloow drivers now appear to like the 6 - 7V range as I see it ... so a 5 cell NiMH or a 2S pack should be ideal.

My favourite is still the pocket driver ... it's a cleaner look without that clip permanent to the plug.

My Glow driver is from the 1980's ... has a single NiCD in and even though it was left on shelf for years - still fires up fine. The other advantage is my B6 LiPo charger in the car can charge it up if needed at the field.
