RE: DL-50 engine
If that Edge is designed like the other modern laser cut super light 2mm ply built planes (ala Extreme Flight) it might be sub 12 lbs with a light glow OS 160. Might even be fun. Start teetering around 13+ lbs with the 1140 squares it has and it will fly like a scale warbird. 80 inch class planes like the H9 Cap is about the smallest the DL should power and still have good wing loading. I hope I am wrong.
Oh, my friend has a Cermark Pitts with a Super tigre 3000 in it and it must weigh like 17 lbs. It can barely get out of its own way. I think its an older version, 5+ years old.

RE: DL-50 engine
Well I just did a side by side comparison between the Cermark Edge and the GP CAP and the differences are so negliable that they are not even worth mentioning so I'd have to take your bet and say this thing will fly well with the DL-50 in it if Paul does a good job of putting it together. I'm sure that after all of this fuss that is assured.

RE: DL-50 engine
I hope it flies really really good so I can bring another dl powered rocket ship to the websight and say how versatile and great this motor really is. Because it makes my 16 pound yak blast off.

RE: DL-50 engine
The Pitts flies very well, on a BCMA 26cc. Anything bigger would be ridiculous and impossible to land. Bi-planes come in fast enough without stuffing an extra 2 pounds in the nose. BTW Check out Adam Vorhies (BCMAs owner) latest plane in this gallery. The Cermark Edge 540.

RE: DL-50 engine
That edge looks to be good @ 12 lbs. Too bad the ailerons aren't longer. I still think its a bit small for a DL, but no doubt it will still fly. We had a .40 size Lancair with a YS 120 in it at the field, till the wings folded.

I used to fly a GP 45 Cap232 with a YS91. A lot of power. Unlimited vertical. But not much fun as I have to watch for stall all the time.
Everything is about choice: experiment this or that is one way; analyze this or that is another. Again it is a choice.
Outfit and fly right, gas planes can have a life span much longer than glow ones.

RE: DL-50 engine
Hey guys
Just a little update on my extra progress. I know that this is a DL-50 forum, but that is what is going in it.When I received the kit the fuse had some cracks in it, a hole in both boxes. A replacement one is on it's way. I started assembly to see how everything is going to work out. I still have to work out the throttle and choke linkages because I would like to run the engine a little on the fuse, but since I have not epoxied anything together on the engine mount (it is just screwed) until the new fuse shows up I will wait and be safer. Do you think that HS645MG HT 133oz/in will be enough for this, or should I go more and digital?

RE: DL-50 engine
As Lou said, i got the 27% GP Cap 232 with a DL 50. The plane comes in at 13.5 pounds. I think the wingloading is around 25-27oz a aquare ft. It was designed for a fuji 43cc wich weighs 1/2 pound more than the DL. Was very surprised when i flew it to find that the plane has FANTASTIC low speed characteristics. I have done some stall testing on low rates and it didn't want to drop a wing, on low rates! I couln't even imagen it with an os 160. LOL

RE: DL-50 engine
Okay guys, got the DL out again today. I got another 5 flights on it. Man, it is really running better. I richened the HS about 1/8 of a turn and leaned the LS a hair. I have around 1-1/2 gallon through it now. The transition is REALLY smoothing out but still a little rough. It has also stoped missing like it used to. It is just really getting impressive. I can't wait to get 4-5 gallons through it. From the way things are going, it looks like it is going to become a really smooth engine. I don't know what the RPM is but the plane is hovering at 1/4 stick. It really pops out when i want it to also. This is with a 22-8 also. I can't really go above 22 inches on this plane. Maybe a 22-10 after more run time will be the ticket?
Great engine!
Great engine!

RE: DL-50 engine
Well I started my DL50 for the first time yesterday, and all I can say is man this engine runs great. We ran 3 tanks through it on the ground just because we liked the wat it sounded. The low end transition is great no burble.
I also got my first three flights in today. I have the DL mounted in a Wild Hare 50cc Sukette with a JR 9303 2.4 spread Spektrum radio. AUW of the plane is 17lbs 6 oz., I'm running a Xoar 22x8 and after the 3rd tank I was getting 6760 rpm with a relaible idle of 1550rpm. Our weather was about 40 degrees and overcast at 900 feet ASL. The only reason I quit flying was I used blue loctie on the muffler bolts and they came loose and I lost one. Next time I'll use red loctyite unless someone has a better solution.
The DL50 is a perfect match for this airframe. In fact two DA guys at our field were waiting to see mine run before they bought theirs, Their last words were they were headed to place their order.

RE: DL-50 engine
I also just got my DL 50 started for the first time today.
I have run about a half tank through it and I am going out and finish up the other half.
Yes it does sound good, can't wait to get it up in the air and get some time on it.
I like it

RE: DL-50 engine
I've had a lot of trouble with my muffler coming loose also. This time I took your advise and threw the paper gasket away and went for the rtv silicon. I hope you guys are right.
N57tc nice looken sukhoi my buddy would be very jealous. He loves those planes. It's good to see you in the picture also. Get some video.

If any of you are afraid of a wing loading of 30oz you haven't been flying long enough, and should not be flying anything larger than a trainer.
If you want to fly a glider than build one.
But a good snap role doesn't happen untill you get up in weight alittle. A wing loading of 25oz snaps ok. But my edge with a wing loading of 32oz snaped like a dream. And don't even get me started on flat spins!! If you fly around on a harrier or a hover all day a very light wing loading is great but for anything else the heavier plane is just fine.

What flies like a dream? My Cap with 1275 sq's and 12.5 lbs wet. Flew like a 40%. It would hover with my OS 160 but pullout was slow. DA 50 made it 14.5, a slight sacrifice in wing loading for rocket vertical. So that Edge with a DL is going to be a couple of pounds more than it could be with a good glow, thats all I was trying to say. I am sure you will have great fun with it.

RE: DL-50 engine
Hey---what's happened to all the great DL50 posts? I learn a lot just reading them. But, the last 24 hours, it looks like everyone is on vacation or at the mall shopping?
As I am finalizing mounting my DL in an Extra, I especially enjoy pics of the various installs you all have done. They are very helpful. Thanx
Happy Holidays
