Do these run off of your receiver battery or do they require a seperate battery?

They come either way, some have their battery and some will run off your receiver battery.

was looking at this one, but I'm not certain if you can use your receiver battery w/this set up. Seems like this one might require a seperate battery.

I remember seeing someone running one off his battery but after further checking I see where they don't recommend it. Sorry.[]

Sullivan recommend that you run a separate battery for theirs.

The Sullivan glow drivers recommend that you provide a seperate battery for the glow, and no run off of the receiver battery. I HIGHLY AGREE. Glow drivers pull a lot of juice when they are activated. They can very easily drain a battery while in flight. And if this is your receiver battery then you are not going to have any power to run your radio in the plane, which of course means a crash. If you run an on board glow system you will want a seperate battery for it.

What size battery would you suggest for the glow driver? It's for a SAITO 150 if that makes any difference.

I reviewed the Sullivan unit and I found that went through batteries pretty quickly. I had a 4.8v 1600 Mah battery for a twin engine plane and one or two flights would drain the battery.

Why are you looking for an onboard glow system?? Simply for when you start the plane??

Ken

Yeah, the engine will be inside of a cowl and mounted inverted, so I would like an onboard glow for starting mostly.

All that is going to do add dead weight to the plane because you are putting a second battery in the plane. You could consider a setup such as this. [link]http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXD693&P=7[/link]

This simply remotes the glow plug outside of cowl. You can still use your normal glow driver to start the plane.

Ken

hmm, might consider that. Perhaps run that lead wire through the firewall and install on the side of the plane somewhere?

That's what I did when I reviewed the Hangar 9 Sundowner F1. [link]http://www.rcuniverse.com/magazine/article_display.cfm?article_id=929[/link]

Ram Products has some good ones I have used them. Set them up where they only come on at about 1/4 throttle. I haven't had a dead stick since. Very little weight difference.

I use this on my RV 4 http://www3.towerhobbies.com/cgi-bin...9&I=LXBC35&P=K
I cut the cowl part off and run the wires through a switch. I have a 1.2 volt 2700 mah nicad battery. I just use it for starting and it works great. Very light in my opinion. Also keeps your hands away from the prop.

I’m using both Sullivan and RAM on board glow drivers. They both work very well and both use a separate battery. Now be forewarned the RAM will only work with a 4 cell battery to your receiver. I have talked to RAM about this and they conform this. So, if your going to use a 5 cell, A123 or lipo to your receiver go with the Sullivan.
