Did you get an NGK plug? Ive never used the plug that came with the motor. I heard theyre junk, so i want with an ngk right off the bat. I also opened up the gap a bit. Never had any issues with it. I dont remember the gap off the top of my head, but i want to say something like .026 or .028". Im sure someone will chime in with the sweet gap. If i remember later, ill pull mine out and measure it for ya.

I did. NGK CM6. You're right. I've had the stock plug actually fall apart in my DLEs before. I also have the newer ignition that supports upto 8.4v and the beam mount kit for the DLE20.

I have a few of the RCExel opto kill module but never lasted long for me. Eventually they start killing the ignition by themselves so I don't use'em anymore.

Now, granted, I'm a bit ham-fisted but I was shocked how brittle that piston ring was. It may have something to do with fact that I had that motor spinning a 13X9 3blade at 10,500 RPM WOT on the BF110.

At 10.5k, that's an engine running on luck. Many have tried it and have blown bottom end bearings to prove it's not a very good plan? I understand they are pretty impressive until they let go though!

I pulled some wires out of my ignition. I went with A DLE30 unit as a replacement. It ran much better with it than the DLE20 with stepped timing. With the DLE20 ignition, it wouldn't idle down well. It would hang on a high rpm for a few seconds before dropping down to idle. Very irritating. They need to ditch that igniiton.

What beam mount kit for DLE20 are you talking about? Its already a beam mount style engine.

I was having some carb problems with my DLE 20, the engine started to bog down and quit just off of idle. The engine had only one hour of runtime. I took the carb apart and found a blue, glue-like junk in it, so I cleaned it, put new diaphrams back in, started it up and same old problems. No matter what adjustment to the low or high needles made no difference. I had a new carb for a DLE 30, so I put it on and so far, things are MUCH better. The engine responds smoother and returns to idle much quicker than with the supplied carb.
Has anybody else had this same situation and has anyone replaced the carb with the "30" unit?

Sometimes when the stock carbs start acting up no amount of rebuilding or adjusting seems to help and then the best option is to simply fit a genuine Walbro carb .... problem solved.

I wonder if there is a clog somewhere internally, causing a lean condition on the low side. So no adjustment will allow enough fuel to pass through to fix the issue. I wonder if something like an ultrasonic cleaner would work.

The only difference between the DLE20 and 30 carbs are the size of the venturi, right? Since we can simply lean it out with the adjustment screws, seems like a good upgrade. Maybe the larger venturi will lessen the chance of getting it clogged up?

By the way, anyone know the part number for the Walbro carb for the DLE20? Just for future reference, if needed.

Thanks

The Walbro match for the DLE 20 carb is WT793-1 Another match would be the carb for a ValleyView 20 engine, which is a Walbro. I don't know the carb # though. It may be a 793.

I am well pleased with the "upgrade" I did by replacing the 20 carb with the 30 carb. I only had to lean the low needle about 1/16 of a turn and did not have to touch the high speed needle at all. Transition is much smoother and the drop to idle is instant. I am getting 8210 rpm at wot with a Falcon 16x8 prop. Idle is 1800.

Maybe this will help those that are having similar problems.

Maybe not.

When I can make an emergency repair from my parts box, it is great for a quick fix. It is not however the sound advice I would give to others as an "upgrade". Next thing you know people might start thinking that the DLE 20 is a great engine but you should replace the stock carb with the one from the 30 for better performance before your ever put it in an airplane.

Even if DLE doesn't know anything about engineering the people at Walbro do. They make a whole range of carb sizes so we can get the best metering with a certain displacement.

Practice vodo if you want, but, I bet your old carb could have been cleaned and rebuilt. You were just unable.

Yes a carb does have enternals that can fail, it is just very uncommon.

Please don't take this personally. It is just others are watching.

NOTHING MORE, NOTHING LESS...MR. MYERS!!!!!

Walbro does not make the carbs for DLE. They are clones.
"vodo"....You mean "voodoo"???? LOL

The carbs are made by EMAS in China

sorry. I meant to say that I have two back plates that allow you to mount the motor with standoffs

Hi!

I'm building right now, a 2,35m wingspan trainer, and I'll use DLE-20cc. But I want mount with REALLY GREAT rubber mounts, to minimize vibration effects, because will use these plane as aerophotogrammetry platform, to test few Cams, Lens etc.

Anyone experienced, could help me regarding this issue?

Thanks in advance!

I used the Dubro 120 size Iso beam mount
http://shop.dubro.com/p/motor-mount-...essories?pp=12
for my DLE 20 on my 120 Ultimate, the results are amazing. I also have Matt Kebabjians soft mount for my DLE 35, I would use nothing else on 30cc and larger engines. For your camera I,m sure you know two issues exist shake and high frequency vibration you can have one without the other or both. You can see shake, touch your canopy with the tip of your finger nails and the electric shock type buzz you feel is the high freq vibs.I think both will affect the camera. Thats the way I see it about the mount perhaps someone can give info on actually using a camera on-board. Hope this helps

PS Matt is the soft mount Guru so listen to him

Does anyone have a weight on the Dubro aluminum mounts?

6 oz for the largest, if weight is an issue Matts soft mount is the way to go it is very lite.

Be careful it wouldn't fit the rear mounted muffler dle 20 ra unless it's all the way to the tip of the mount

The muffler hitting the rear bolt is not a serious an issue as the muffler hitting the washer under it! The bolt can be changed for a flatter type, but that washer has no place to go.

The universal types that RC Extreme Power sells are adjustable in length.

Call them and ask?
