Hi John
If you want to quiet it down try here http://www.gashanger.com/index.php?o...d=68&Itemid=75
A bit expensive and you will loose about 300 RPM but it does work.

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.

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

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

Make sure your fuel tank's vent line is unobstructed, i.e., no kinks.

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".

Suggest putting the spring back on as it is needed but do not hook it on to the arm.

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.

does anyone have a good source to buy the spinner adapter nut? I ordered one from horizon a while back but I dont like the way the threads feel on it. The 8x1 nut is kinda hard to find.

Thanks,
Jeremy

Tower sells one that is part of the .60-size P-47. You also might pick up a tap and clean up the threads on the spinner nut you have. Bye the way, the DLE 20 is a GREAT fit for the Top Flight P-47. Flies great with a 16x8.

ill do some more searching on TH. their search function can be kinda finicky, but I can find it. thanks.

Oh, and the DLE20 is apparently a great motor for a lot of planes! Ive used it in my 70" revolver and its awesome. ive seen videos of it in a P51, a Zero, Extras, Edges, and Ive seen it in a stinkin' trainer!  Ive just put it in my Goldberg Egde 540. It is an awesome little engine, and in my opinion its a Glow motor killer in anything from a 60 to 120 size plane....

I got the spinner nut and flat nut for the DLE from TH, but the flat nut didn't fit, the threads dont look correct, so thinking it was mislabeled. So I used one stock nut and the spinner nut. Makes it easy to start, and added a little nose weight.

30:1 ratio is about 4 oz of oil per one gallon of fuel - right?

yep. I run 30:1 Maxima 927 castor oil. Motocross race oil. Smells way better than any mix ive ever smelled. I used it for a decade when I raced motocross, so I enquired to DLE about it and they said it would be a good oil.
