Dig it

I'd like to make my own onboard glow. I have some ideas but I'm wondering if anybody has any plans I can check out, or thoughts I should ponder. I don't want to buy one, its a project for me.

My brother made a very simple one that used a single nicad battery, remote glow plug adapter, and a switch. I don't remember exactly how he made the hookups for a charger but it was all common stuff available at Radio Shack (with the exception of the remote glow adapter). It was always on or always off. Some say running it like this burns out glow plugs quickly but he never had any issues.

You'll need to buy, or make, something like the Sullivan "Head Lock" remote:

I've seen photos of a "C-clip" or "e-clip" (that fits the post of a glow plug) with a wire soldered on instead of using a store bought adapter.

seanreit. Ya, I did a search and got exactly what you got, 99% of it is what one should I buy, or which one works best. Like I stated, I'm not looking to buy one, I'm looking to make one as a project.

carrellh. Thats basically what I had in mind but I'm thinkin that I'd like it to work off of the throttle servo so as it reaches the idle stage, it would kick in.

Anybody else?

Well, operate it off a switch then with an additional servo, or use your throttle servo.

seanreit. So, that is simply a on/off switch that could be triggered by a servo arm? Ok, I like that. Can't see why that wouldn't work. Now, if a guy took a normal JR/Hitec switch and put that in the circuit to a rechargable "C" battery, you could also use the charge jack so as you would never have to take it out of the fuse eh?

Or place a resistor on a down line from the battery that is an activated circuit of the switch, so at low throttle you are lighting up the glow plug with the main battery. I don't think I am brave enough to run that system, but with a high enough capacity pack, I could probably be talked into it. There is probably not a lot of load on these smaller aircraft electrically at low RPM at the engine.

hmmm, ya, I don't think I'd want to run it off the rx pack. Do you not think the C battery will provide long enough life to support a flight?

....a C cell is fine. Use a micro switch and fashion it to the throttle servo so that
it turns ON the battery at 1/4 throttle on the way to idle. It will cut OFF when you
throttle up past the 1/4 point.

You can use a regular battery. You don't need the expense of a nicad and charger
on a home made set-up. You can get a single C-cell battery holder at Hobby Shack.
Use the cheap C cell batteries from the 99 cent store.

You can get a glow plug clip from Cermark.

I made, and used a home made set-up like this many years ago....it worked fine.

Ok Dig It.I'm not sure Exactly what You define a "Project" as.But,If assembling it counts,I like this one http://www.hansenhobbies.com/products/rcelkits/erskit I add an LED to show when the "Glow is On", and connect it to a spare channel on the receiver. Then I mix the throttle channel into the "Glow Driver" channel. That way the throttle will turn it on at low throttle while flying ,AND the "Glow" channel turns it on at all throttle settings for starting the engine.

go to my site www.thecubden.org About the 13 one down on the menu is instructions on how to build on board glow. I have been using this setup for several years now and i have it installed on two planes

I used a NImH battery, a small microswitch, a remote glow kit and a wheel collar. I put the wheel collar on the throttle linkage, and mounted the microswitch under it. When the throttle is trimmed for idle, the microswitch is engaged. When the throttle and trim is all the way down, the switch is disengaged. When the throttle advances to about 1/2, the microswitch disengages. Adjustment is made by moving the wheel collar on the throttle linkage.

That seems like a great idea but it seems like it might be hard to get it all working right. Do you have any pics closer up of the switch?

Have you had any problems with it?

Is that the spitfire that you have the ventilation fan on? Its amazing what all you crammed in that cowl

Wow, awesome stuff people. I'm well on my way.

Thanks
