New DL-55 and DL-111

[RTK]

On a strong 50-60cc engine the Vess 23A or B are LOUD, They seem to growl more than rip. A menz-s 23x8 is much quieter but does not have the instantaneous punch as the Vess's, especially the A.

ive run the 23a's on my 55,7400rpm. i thought it was very loud compared to the props iv'e tried. xoar 22/8,menz 22/8 23/8 and mej 22/8. but i thought it has the best pull from out of a hover but as you do a long upline i feel it looses alittle more steam compared to the others. it's just trial and error with your flying style and airplane. we all have our favorites. but works best for you is the best.

Hey there Pat how are ya I like the 23A on my DLE-55 as it is the only prop that I can use to get the burble out of the engine. Finally got the engine to run half way decent, thanks for the help Pat. I have to tune it every day I fly but am able to get it to only burble 2 clicks off idle. It harrier rolls and hovers OK and has tons of pull out and correction power. The new carb and reeds realy helped. I do have to say though it does not even come close to my new engine that was modded by sola I'm rippen a 28X10 Mejz with out an effort and it runs sooooooo smooth with the MK cans. But there is a trade off the new engine was $1,300.00 after mods a DLE-111 is much cheaper.

What type of mods and engine are you talking about??

[davidjensen]

OK I need to define "ran like crap". The needles were super sensative. It was either too lean or too rich with just a 1/8 turn of the high end needle. The engine ran OK on the ground but once in the air it would not transition well and was either rich or lean i don't now. The engine has sat for almost a year and I don't think I move the needles any during that time.

davidjensen, did you take your carb apart and give it a cleaning?
If you did not take it apart, the hard starting may have been due to sitting for a while. The rough running may be due to an orfice or screen having some junk in it? Not sure if you checked all this yet.

Ported and polished, Carb is gone through and everything reeds, pop off blah blah is tested and set correctly!!!!!. If they dont meet the specs/tests then replaced with parts that do work!!!!! (Something every company should be doing actually checking the engines and parts they sale) See many years ago we expected this type of service because that is how it was!!!! People actually cared what type of product they sold you. It was about reputation, integrity not just money and the bottom line. Anyway also the Ignition recurved for smooth mid range. Custom headers also ported polished to match perfect fit to jugs. Ads another 200 RPM to the equation and an engine that purrs like a kitten at any throttle setting. I adjusted the needles to factory setting two weeks ago 1 1/2 high 1 3/ 8 low and have not even thought about touching them since. The engine pulls like a mule and only use 3/4 throttle for any up line at any situation otherwise it rips the 28X10 prop. And I have yet to hear it even slightly burble I can not say enough about the performance and most of all I am not dicking around with it to get it to run. Don't get me wrong I like to tinker just like the next guy but my DLE is a piece of junk tunning the carb every flight. Its a DA 100.

I bought 2 new Walbro WJ71 carbs for my 2 DL100's. Set the timing to 32 - 34 degrees BTDC, it was way out before (45 degrees BTDC which I ran that way all last year, engine ran good other than a little low in rpm at WOT).
Differences that I noticed so far between the EMAS carb and Walbro carb:
EMAS: the H needle almost did not have enough turn left to put it into a rich condition (would only drop the rpm by 50), the L needle had lots or room (easily go into rich condition), needle a little tweaky (very, very little movement to get a response), transition good, midrange good, idle good.
Walbro: the H needle had lots of room to put it into a rich condition (would drop rpm by 300 or more), needles were very smooth (had lots of movement to get a response, ie: move a little to get a little response), transition good, idle good, midrange good. The L needle did not have a lot of room to go into a rich condition (would only drop the rpm by 100). The biggest advantage of the Walbro carb over the EMAS is the tuning of the needles, very smooth. I like having the little bit of extra room to put the carb into a rich or lean condition as in the Walbro carb, but both carbs where able too (just the EMAS left very little room on the H needle). Checked the plugs and good colour on both plugs so needle setting are good.

My DLE111 with the EMAS carb runs well, good transition and idles well. It has one bad tendency. I get intermitent fuel disruptions (like a air bubble). It may happen in straight level flight, up lines or at various throttle speeds. I get maybe some four to eight burbles in a tank. I have a second identical Sbach with a DA-100 and the Walbro carb. I've never had a burble with the Walbro. Is this a characteristic of the EMAS carb? Would changing to a Walbro WJ71 carb help?

The EMAS carbs I have ran well. Like I said, the biggest plus is the needles are not very sensitive which is why one is able to fine tune it easier. I will keep my EMAS as spares.

Looks like I am going to need a new crank and rod for my DLE-55. The rod bearing has developed a lot of play causing it to rattle very bad and it was getting worse so I pulled the cylinder to check it. Everything else still looks good. Up until this it was running great on an RE2 tuned pipe. I have been running 50-1 oil mix since I started running this engine last May. I couldn't tell you how many gallons I have run through it but I can say I have flown the heck out of this engine. I just wish they would put better rod bearings in them.

[Oilsands]

Some motors have 3 crank bearings, some have only 2 (to help keep it lighter). This only has 2, so they could be a little harder on bearings.

Ya you betcha

[tater1]

good to see you on here,you and your brother were so much help to me in the pattern contests, back in the 90'sI am now playing with the gassers,dle55 and an aeroworks yak.All the best.
