Status: offline 		Yeah. We opened the low a bit to make sure we could get fuel into the engine. It being new. Didn't go much in the high side other then checking rpm. I think we gave it less then a quarter turn. The engine runs great for the several minutes in runs. No hesitation no stuttering. Up until the second it just quits Moved everything back to factory setting in an attempt to clear the problem

I'm using lawn boy oil mix so we are seeing a small amount of deposit out the exhaust as you would expect

It's just kind of wacky

I'm pulling the engine and will have the guys at the field take a look at the carb this weekend but still don't know how to eliminate the ignition as a possibility

Status: offline 		Well, I had my second flight with the 4* the other night. I switched the prop to an APC 16X6 and it woke it up.  I did not touch the needles on it, and it ran good. No transition issues like the first time with the MAS, temp was about the same, except lower humidity.  It idled down good, a quick touch o throttle got the RPM's up and it idled down nice again during my final, so looks like I got the engine dialed in well for the next gallon or two until it is finally broken in. When I landed after a 9 minute flight, the engine was cool, as in if I touched it I wouldn't get burned.  Has a little burble to it at high end, but no performance issues. I think the 4* has a 12-14 ounce tank and I used 1/4 of it for the 9 minute flight, which should relate to 30 minutes of flight to the tank. Wow!  Big difference between the APC and MAS props on this plane.  The MAS used much more fuel. I burned up a whole tank in 15 minutes with the MAS on. 

Hooked now on APC props, have them on 3 of my planes that used to have MAS K.  All three fly much better.

A bit expensive and you will loose about 300 RPM but it does work.

The 20's really like the APC 17x6. If you get the chance they are definitely worth a try. Going that way will load the engine a little more, and might even help clear up that burble? -Al

Status: offline 		All the LHS had was a 17x4, otherwise I would have tried it.  For now I will fly with the 16x6 and order the APC when I have other items to order.   Once I get my landings smoothed out where I stop bouncing and knicking the prop, I will go to the larger one.

Thanks Falcon, that's interesting and will maybe try this option if I don't have any luck with Lifer's suggestions, didn't know anyone was doing these here in the UK, I'm very envious of the availability and prices of RC stuff that are available to people in the States.

Thanks also to Twin-flyer, but as I previously posted we are being really hard hit by customs and excise on buying anything from the States, a few years ago this was not a problem but now it is. As an example about a year ago I mail ordered a Aeroworks Prox .60-.90, after paying postage, import duty, vat, and, insult to injury handling charges it cost me around £240.00 thats around  $375.00.

Cheers,

John

Status: offline 		Something to look out for on these DLE 20s is the spring clip for the throttle shaft coming off. Then the spring pushes the throttle plate againt carb barrel side and distorts the plate. Had this happen twice. The sign was the engine wouldn't idle down. Too much fuel and air leaking through the distorted area. I tried to fix by hammering out the distortions and filing the edges down smooth. But couldn't get it close enough. Still leaks but will idle down slower. Need new carb but every one is "out of stock".

Flying fields have been lost because of the noise. What we like and what the rest of the community likes are two differnt things. 


Completely understandable, but I think this conversation started as a "what I like" thing. So that's where my side of it is coming. So to tell eachother that this sucks, or that sucks is different. That is simply opinion.

The 20 is perfect for the old man next door who stole my trash can and dumped the trash on my lawn because he feels my trash can should be behind my fence so he doesn't have to see it! I need to do some tuning today for a matter of fact.....

Oh, no. I was talking about someone else's comment about the volume. Sorry for the miscommunication. Its kind of a dead subject now. I just hadn't been on in a few days so i didnt see that the topic has changed to a tuning question. I was just saying that i understand what you are saying and that I feel there is two sides of the noise issue. One side is how we as flyers like or dislike the sound of our planes, and then on the other side of the coin is the issue of nuisance to the community. Luckily I fly in a remote location so its a non issue.
