RE: Are On Board Glow Drivers Worth the $$$?
[quote]ORIGINAL: iskandar taib Hmmm.. Is it really all that complicated - or expensive, even? http://www.hobbyking.com/hobbyking/store/__17157__On_Board_Glow_Igniter_1_5V_3A.html Iskandar [/quote] Yes. Like the first thing I will do when getting back into the hobby is to buy a glow driver or electronic ignition! Actually right now I am building a rubber powered free flight. So yes, for now it is too complicated and expensive. [quote] A glow driver does not improve performance [/quote] You are assuming that I and others care. Till I am burning a lot of self mixed fuel, I won't care. I am adding this because I now understand that I sound rather obnoxious. I am just explaining that many do not care. If they are getting good performance and reliability from their glow engine as is we won't bother with this and the glow driver looks a bit simpler and is a bit cheaper. What you said has merit and I may consider this in the future. And BTW it doen't look much bigger than a glow driver and I have used a glow driver in a 60 sized plane before and probably not too large for a 40 sized. But I rarely have issues with power and reliability and have only had periods where I flew enough to be that concernerd about fuel economy. When it was an issue I simply started mixing my on fuel. Not much more expensive than gasoline fuel mix's then.

I disagree with Novel that the gasoline two stroke will not hold up to the heat. But if you need 20% oil for the con rod, then petroeum oil may foul the glow plug pretty quick.

RE: how? More smoke
Many people are using high nitro fuel with a hot 4 cycle plug. This advances the timing causing detonation which requires a richer mixture which makes the smoke worse than it would have been. If you lower the nitro or use a cooler plug you can lean out the needle and have less smoke. There are brans of 4 cycle plugs that are cooler than the standard OS F plug which for most 4 strokes is the right plug for 10% nitro or less.

RE: Are On Board Glow Drivers Worth the $$$?
[quote]There's nothing complicated about "multi cylinder" CDI systems either. And, you comment regarding CDI being somehow less stable on engines that are being broken in is ludecrous given the more stable ignition timing of CDI & how can the oil collecting on the (spark) plugs be more of an issue W/CDI when the engines are running 20% leaner?[/quote] I should have said 4 cycle not 4 cylinder. And I did not say anything about CDI it was a reference to on board glow and oil in the glow plug not spark plug. The oil is a problem without onboard glow not with. Please stop trying to read between the lines. [quote] There's nothing complicated about "multi cylinder" CDI systems either. [/quote] Except there may be more pickups and or coils, depending on the method used for the CDI. Not a problem with a single pick up I suppose. But you still have to worry about the firing order, sometimes with interferance. IMO installing the pickup is enough to go to on board glow. Especially when you plan on removing it when the engine is broken in. Your 20% gain in fuel economy is only for those who use a glow plug too hot to begin with. I am sure the gain is considerably smaller after I have picked the glow plug with the highers RPM, and usually the leanest needle setting. Having burned maybe 3 tankfulls of fuel last year, I don't care if it saves 100% of fuel. I need to burn some fuel!

RE: Are On Board Glow Drivers a Waste of $$$?
[quote]ORIGINAL: TFF I like ignition on glow fuel, but I will play devils advocate. If you are using onboard glow to cover up an airframe or tuning problem, it is a no no. A person who does will be the same one who cant get the ignition to work reliably. If you are just using it for a way to not hook up external glow or lower idle for a scale job it will be a wash. more hp with ignition, but when you have a problem you have to have to have more than just a glow plug to get going again if you are willing to light the glow plug with an external drive. Its a hobby and there are a lot of neat ways to do things. [/quote] On board glow is used for inverted and multi cylinder applications. The latter of wihich would be more complicated with CDI.

RE: FP or LA
[quote]ORIGINAL: Hobbsy You must have really dirty air in Ga. I have Fox airbleed carbs, Enya airbleed carbs, OS airbleed carbs and have never seen that happen.

Ok, you can get trash in the fuel and end up with the same problem, but with an air bleeed you can get trash in both air and fuel and end up with a dead stick. Not that it happens that often, but trash in the orifice of an air bleed does happen and it can cause the engine to quit. I have seen it happen at least a couple of times, both right after take off.

RE: FP or LA
[quote]In my opinion there is nothing more reliable than on OS LA.[/quote] Oh come on! It has an air bleed carb! That means that any small amount of dirt getting into the oriface will change the mixture. Any twin needle carb will be more reliable, OS makes some fine carbs. However the same cannot be said about their ABC liners. The later LA liners are better than the older liners and likely the FP. However for the most reliable I would go elsewhere, I have seen many air bleed carbs give trouble because of dirt in the orifice.

RE: FP or LA
I think most FP's were ringed or cast iron. Maybe there were some ABC versions right before the LA came out, not sure. IMO you would be better with a ball bearing engine and someting more reliable than an LA with its bleed air carb. I would go with either a Fox 40 deluxe ABC or TT Pro 40 if you are after a 40 size. I just wouldn't mess with a cheap engine like the FP or TT GP.

RE: Propellers
They make tooling to cut wood on metal cutting machines, just contact some tool suppliers. When you do ask about the turning speeds as this would be different for wood as well. You will need to sand, and finish with nitro proof varnish. I would simply spray with epoxy varnish. Weight shouldn't slow down the eingine other than taking a little longer to rev up. If the prop was 15% more efficeint that alone would slow the engine down. you would need to change the diameter or pitch (or both) of that design to bring the rev back up.

RE: TT .39 heli engine ruens glow plugs
4 yeas old isn't a requriement to overhaul an engine, in fact that is almost new. I have one engine that is 30 years old. I have never torn it apart, never used afterrun oil and it works fine. I suppose many here would tell me the bearings are bad if I posted a pic of them here, but they are not, its just castor oil stains. It does need a new ring though, it also needs a sleeve as you can feel the wear. If the bearing is indeed bad then replace it. Otherwise the new one isn't likelly to be any better. The old ring will break in a lot faster than the new one and it won't cost ten or fifeteen bucks. And may last twenty years depending on how well you take care of it.

RE: TT .39 heli engine ruens glow plugs
I agree. Metal to metal contact is not bad, in fact the engine head has metal to metal contact and needs no gasket, it is just smoother. Many engine mufflers are the same way, when new they provide sufficent seal with no gasket, but loose mufflers, handling with no muffler, and poor sealing surface on aftermaket mufflers will ruin this. In that case it is better to put the RTV on wet and tighten up the muffler then wipe off the RTV around the joint. You most likely will not have a smooth enough gasket surface if you let it dry.

RE: mode 1
I can't imangine switching between modes. I can fly Mode 2 with a three channel transmitter, I just take my had off the thottle. But with 4 or more channels you need to rest your thumb on the stick for rudder. I do ok for a few minutes but after a while I will eventually either chop the throttle or push it full throttle instead of elevator and/or give up or down elevator instead of throttle. Not a huge problem, except on landing, then it is a huge problem!

The warbirds may feel lame compared to these planes. [/quote] The DB is not intended for a tail wheel. In fact it would be hard to do because the rudder extends below the fuse. The Killer Chaos is intended for a tailwheel and the tail and rudder is built to allow a tailwheel. The Utter Chaos is the trike version and the rudder is in the way for mounting a tail wheel.

Also can you take a very clear picture of the top of the piston and the chamber on the head? Also since you have it apart why not clean the baked on oil off the case. run it in antifreeze in croc pot set on high for couple of hours. new bearings, new ring and cleane case = almost new engine.

RE: TT .39 heli engine ruens glow plugs
[quote]If the engine is apart its best to do the bearings. The only way to truly examine them is to remove them from the engine, put a side load on the bearing and turn it with your finger to see if its notchy, but for the price of a set from RC Bearings.com if you're going to do that you might as well throw them out and replace them.[/quote] There is no need to remove bearings to see if they are good. First make sure it is clean of all dirt or congealed oil. If so then they should feel smooth. Second check radial play, Try to move the crankshaft from side to side, they should be a little radial play, a lot means a worn or poor fitting bearing. Next remove the glow plug, with no fuel, and a small prop and a fresh starter motor battery turn the engine as fast as possible, you should hear little to no bearing noise. Then run the engine, you should hear no bearing noise that is audible over the engine noise. I suspectg your bearings are good, no need to spend money on new bearings. Some people here would replaceeverything every time they have a chance. I guess it depends on what rock's your boat.
