Nice picture,
What is that white connector plug in to the crankcase? Ah may be a heater for the case?

chuck, what side of the plate did you insert the lip in. I think i am going to be heading to ACE today to try and grab one. Can they be purchased at ACE?

That's the supercharger. Seriously, it is the battery connection for the electronic ignition on my G26. The conversion was done by Ralph Cunningham. The plug does not go into the crankcase, but rather in the openning at the rear of the engine where the flywheel for the stock ignition was. Ralph mounts his electronic board in that area after removing the flywheel.

Yes, ACE will have the part. Take the picture with you and show it to a salesman, it will save you time. This picture should make things clearer on installing it, if not let me know.

Another option is to use a nipple off a glow engine muffler and tap the original hole...a little JB weld ensures no leaks. I copied some others that run the tube to an 8mm film cannister in the fuselage, making sure it wasn't airtight

If you use the pressure tap install, you must be absolutely sure to grind off any protruding threads on the INSIDE of the cover, and that the modification is done with the cover removed. Someone who is unfamiliar with these carbs HAS tried to do this while the cover was still installed, and it turned ugly really, really fast.

My method is to remove the cover, drill with a 1/8" drill, force fit a short piece of 1/8" brass tube into the hole, silver solder it in place, clean the inside, done.

I have done this on every engine I've owned, because all exhibited some degree of unwanted pressure variations due to cowling and airflow around the carb. To me, this is "the" "midrange" fix when things act different in the air than on the ground.

You should be careful removing the plate because there is a rubber diaphram under the plate that can be damaged with rough handling. But dont worry, nothing should pop out. I would do the mod on any gas engine, whether the carb is on the side or rear.

Thanks chuck, looks like the lip is on the top of the plate. This makes sence as it gives you more surface area for the solder.

One more question, when you go to redrill the whole in the center should i drill the same size whole as the one on the side.

Cambo,

Just pick a drill size that fits comfortably inside the brass fitting. There is nothing critical about the hole size because there is a very low volume of air passing through it. Just don't make it smaller than the hole already in the cover. Remember to plug the existing hole with some silicone before reinstalling the plate.

I want to thank everyone for all the help. I found the fitting that chuck was talking about in the plumbing department at ACE. I tried soldering it on but really couldn't get the solder to stick to the plate. No matter, a little JB weld did the trick. . I am anxious to try and fly again as it looks like this just might work.

If tuned properly the DL will have the same if not more power than the DA. As for the weight, I "think" the DL may be a few grams heavier, but I am not sure. My DL is in a WH 87" Sukhoi and I had to move all my batteries to the nose to get it to balance. There is a person at my club that has a DL in a WH 28% Edge 540 and again he had no problem balancing it.

Cheers

OK fellas-- fired up my first DL50 today. Airframe is a GP Ultimate. Dollar for dollar I think it is one of the better deals around. Of course that is easy to say after one tank. Fuel draw was a problem to start as it took 15-20 flips to get a pop, then another 10 or so to get it running. When it started running-- boy did it run. Lawn Boy @ 40:1 and a Wild Hare 22/8 prop was at 6900 RPM after some running and tweaking the needles a bit. The low end was way-- way too rich-- high end was close. Keep in mind this was at 52 degrees (you could see your breath) and 1 hour after a thunderstorm. The air was damp, cold, and very heavy--and still got a max of 6900 on the first tank--idle was 1700, but it shook the airframe pretty bad. It should be noted that I only had the bottom wing attached.

Not bad for $400.

AJF-2 - REALLY glad you're part of the happy users of these. I've been following these since the beginning, and except for some initial growing pains in a very few engines with carbs and mounts.... it's a challenge to find bad press about these.

I am SURE happy with mine, and for the money, just an untouchable value.

Picked up some brass nipples at the hardware store today. I think I will go ahead and to the vent mod to both of my DL's now while I am putting my planes togerther instead of getting out to the field this spring and find I have problems. Here are a couple of quick pics of my install so far in a GP Wagstaff. All the stuff on the cowl is dust from cutting the fiberglass and I hadn;t wiped it off yet. My other one is going in a Giant Stinger.

Question for you all. What is the minimum safe distance to keep the plug wire away from the exhaust when routing it through the cowl?

Well yesterday turned out to be a good day for me, I took my Christen Eagle up for the first time with the DL 50 in it, and they both perform very well,
The engine that was runing a bit rich was consistence with plenty of power and the plane was fast and responsive it was great,

I did notice that the engine that I ran in my back yard doring the week did very well but I did notice a diferrence in performance when I added the nipple and tubing to the back plate of the carburetor Friday night
it seems to me that it ran mutch smoother and not as poppy, all in all I was very pleased with the engine performance as well as the CE it self,

Far enough to keep it from melting Seriously, the farther the better, but an air gap of 1" or so at its closest point should be fine.

You might want to consider openning up the space around the cylinder head for better cooling. There might be an overheating problem in warmer weather.

I always liked the Christen Eagle. It just grabs your attention as soon as you see one.

Thanks Earle, I'll have to look and see if I have enough room to route it between the muffler and the cowl. I would like to get it inside for both looks and so it;s not out flapping in the wind.

Do you think it was runing to lean? My DL new out of the box had the typical TDC connecting rod click that is normal on any two stroke engine,
