Remote Glow System or not?
 
I have read many threads about mounting engines upside down and will they run ok. In many cases, the answers are "yes" it will run fine and you do not need a remote glow system. Let's say the engine works fine upside down. Here is my question: When do you use a remote glow on an engine that runs fine upside down? Isn't the answer really whether not you can get a glow starter on the plug or not? The reason I ask is because at our club, the planes are started on the ground. It would seem to me that getting a glow starter on the plug is only possible when the landing gear is high enough to get the ignitor on the glow plug. So without going to a remote glow starter is there any technique that is used when the plug is too close to the ground to get a glow starter on it?

You can get a remote headlock for that purpose. Sullivan sell one of those formely sold under the Model Products name I believe. Your LHS should be able to get them. If not Tower lists them under flight line accessaries. [&:]

You can turn the airplane upside down to start the engine-hard to do without a cradle. DuBro makes a remote headlock setup you can mount behind the wing on top of the fuselage if you wish. I use an onboard starter on an inverted motor 25% for reliable idle(peace of mind is worth something) and 75% to eliminate the aggravation of old knee problems. It's one more battery to charge but well worth it...JIM

If there is a weight issue you might want to install the harness that allows you to attach the glow starter remotly.
I have a pheonix Sukhoi with a ys .63 mounted inverted. I purchased an onboard glow driver from Dymond models and I am very pleased with it. The odd thing is once the motor was dialed in I only use the glow driver for starting. The YS has an awesome 1700 rpm idle. It did take a bit of work to get the idle set well.
Its not stopping me from installing another onboard unit on a waco bipe and a ENYA 91 fs. I had a number of very bad experiences with a certain ASP 61 fs so all my FS motors will get the onboard system.
You are looking at an extra 2 oz ( at least, depending on what type of cells are used when building the pack) or so in battery weight plus the little electronic gizmo that activates it and a harness.
OH! You need a charger for the battery, An added expense. Its not necessarily a cheap setup but how reliable is your motor, and what does a new plane cost?
The Waco needs extra weight in the schnoz so I opted for 2 sub C cells... 4.2 oz, it should run (constantly if i desire) for an hour.
the smaller pack on the sukhoi was charged 2 monthe ago and still starts the plane.

anyway thats my limited experience with these units. I do recommend at least relocating the glow plug attachment point, It will make your life easier. Dymond has options for that as well.

I hated having an engine quit on the flight line and having to schlep the plane back to the bench and turn it over to start it. Believe me That gets old real fast.
As for the charger... if you get a good one ( expensive ) you will be set for electric flight ( nicads ) allready.
Not all Four stroke motors will idle reliably inverted, many will but if yours wont onboard is the way to go.

For me, it's pretty easy just to lay sideway on the ground and attach the glow igniter to the glow plug. Some of my buddies are not as successful trying to do the same task on my planes. I got good at it after some practice. All my engines are mounted inverted and some of my landing gear are short. I only use remote glow as a very last resort, and I will never use onboard glow driver. Onboard glow just adds extra weight and is one more thing to worry about.

RE: Remote Glow System or not?
 
Thanks for the info everybody. I looked at tower and like the idea of using a remote glow starter connection away from the engine. There seem to be be several brands and I think I will try one of them. I am planning to use this on my Saito 72 that is planned for a U Can Do 46. Not only will the glow plug be hard to get to upside down, but will also pose a problem with it in the cowl. For now, I will forego the onboard glow starter system. Trying to save weight.

Thanks again for the replies.
