I had another fine day at the flying field with the new DL100. What can I say: it’s a hoot! There’s no problem pegging the fun meter with this one.

The carb tunes a bit different from the 50. On the 50, the high speed circuit has almost no effect on the midrange but on the 100, it definitely does. The midrange won’t smooth out with any richness on the high speed circuit. The 50 also runs fine with the needles close to where they ought to be but the 100 wants them set. It’s not difficult to tune, it’s just more sensitive to being out of tune.

Tuned “right’, it’s a bit cold blooded and requires the choke before each flight. It also takes a brief warm up to get the transition not to stumble. Some may consider this a bother but the reward is a very smooth midrange and an absolutely phenomenal transition. This thing responds to throttle like nothing I’ve ever experienced.

The 26B Vess is spinning 7100rpm on the ground now. The way the engine sounds, performs and flies the plane I have no desire to change props. I’ll try some others soon as I’m sure people are wondering about comparisons but I’m having so much fun with it it’s hard to remember to be analytical.

I did remember to keep track of gas consumption. 15 minutes in the air used about 20oz. Remember though that this airframe is on the light side and heavier ones will need more throttle for similar flight. When we start flying the CAP 580, it’ll be outfitted with a 30oz tank.

FWIW, the engine has passed my “test” and I’m going to be happy to sell and support them. Congratulations DL, you have another winner here. Release date has been estimated at May 20th so shipments should start soon thereafter.

Regards,
Bob

Hey guys. Didn't get my maiden in today because of interfearence. It's only when engine is running. I'm posting some pics of my setup cause I can't figure it out.


What kind of reciever FM, PCM, or 2.4?

I have mine set up with both batteries together and a steel threaded rod to the throttle and plastic ball links on both ends. No interference here oh and I'm using 2.4. Many hundred flights with no problems.

From what I have read 2.4 is much more forgiving and almost immune to ignition problems. I have switched all of my gear over to 2.4 and have had no problems as well so I suspect he is running FM or PCM.

I'm using FM. Still can't quite afford the 2.4 retrofit on my radio, but that's my next purchase. I'll move everything around and report back. Thanx guys.

The FM is known for this and you have to have everything set -up just right the ignition needs to as far from the servos and wires for the servos and it would help to run twisted servo wire. This includes the Battery for the ignition.

If your radio has the capblities run a pcm reciever, that will help a great deal.

T.Edney the DL 50 will be a perfect match for the EF Extra 300. I put my trusty DA on the front of my Extra when I first got it......well guess what. The genius I am damaged the sheild on the spark plug wire and fried my ignition.
I just happen to have a DL sitting on the bench waiting on me to finish my Ultimate. I put the DL in the Extra and was very suprized to find that the DL right out the box was just as strong as my fully broken in DA.
To make a long story short the DL will have no problem pulling the Extra around with authority. If you really want to make some HP get a tuned pipe.....MTW RE2 or ES Composite. I have tested both on the DL and beleive me that either of the pipes will make the Extra scream like a raped ape.
One other thing about the DL's. Buy your motor from Bob at DL USA. He stands behind his product 120%.

Does anyone know the puchout or should i say vertical pullout power with it on the extreme flight 300? I love to fly 3d and just wonted to know if it had enough punch to get u out of trouble if the problem ever occured! Thx for any advise!




What he said....lol...pic of my extra with DL and ES pipe on previous page in this forum,....you'll love it!!!

Rush,
Can you tell me the header you used with the ES pipe? Manufacturer, model number? What length?

Thanks

Dave

Guys, i have put about 3-1/2 gallons through it. I know it isn't completley broken in but i just can't get the mid range to stop burbling and missing. My question is, how do u know when the low end is too lean. I did the fix on the carb that runs a line from that little pressure whole on top of the carb. I am still new to gasser tuning. It is not like the engine runs like ****. I can go through all my aerobatics without concern of it quiting. However, inverted flight along with verticle flight lets the engine run so smooth. I just can't seem to get there with my tuning.

Also, I have it set for a high and low idle. Since this is ony a small plane, 13#, i need the low idle to land. The low idle is fairly reliable except for the couple seconds the plane slows down after tuch down. The engine just always dies. Sometimes if i goose the throttle for a second it does fine but if i forget it is a 200ft walk. Really anoying.

What am i doing wrong

Cameron

Cambo,

You might try flipping your carb 180. I had a DL that exhibited similar characteristics after touch down.. plus it didn't idle as well as my other two DL's. I flipped the carb, and it idle 100x better. I'm not sure, if this will fix your problem... because there are a bunch of other variables in play.
