On my 26cc in order to keep the muffler from coming apart, I put a liberal coat of silicon seal between the parts and on both the bolt head and the nut.I have several flights and have no leakage from the muffler.
I tried safety wire on my muffler. It prevented it from falling off but the bolts still came loose enough to let the muffler leak

Success today in keeping the new muffler on and together. I had four 10 minute flight's and not one issue with the muffler coming lose.
I used high temp red silicon on all the bolts and safety wire through the bolts that hold the muffler onto the engine. I had a littler leakage around the two half's where they come together but nothing to worry about. I also checked the end cap nuts that hold the two half's together after each flight and they where only slightly lose so a little turn on the nut and that was that.
The NGH GT17 is running real good now. I am getting 9000RPM on the high end with an evolution 14x8 prop and 2000RPM on idle. I am planning a winter project and I just my order another NGH GT17 to go into that project. I do wish I could find a verturi fo this walbro carb so I could use some nylon stocking as a air filter.

It does not say what carbs it will fit though
It does in fact say it will fit a WT carb. I am going to get one

I bought 2 of the black stacks & like them. They are somewhat flexible. I took the brass eyelets out & found out it then can be pressed fit on the carb bolt head portion. It will stay right on & you do not need to even take the car bolts out. Thus avoiding a leak in any of the carb gaskets. Capt,n

I got mine for about $2 each. You may need to measure carb bolt head dia & drill one size smaller...that works great.

Just got back from the field and I got another 6 flights on this NGH GT17 engine on my Escapade and this is a great running little engine now that I have the muffler issue figured out. I am gettign 9200RPM with an evolution prop and a very good 2000rom idle. I am now sure the whole problem was with me over tighing the bolt and bending the muffler. If I need another small engine oif this size I just my buy another one knowing what I know now!

Now that I have the muffler issue taken care of I have at least 20 flights on the NGH GT17 on my Escapade and this combo is fastly becoming my favorite. The NGH GT 17 has become a very dependable engine and I am getting well over 9000RPM with an evolution 14x8 prop. I am now breaking in a OS GT15 that I bought and I hope the OS GT15 is as good as the NGH GT17. I am still breaking in the OS GT15 and it was a bear to get started but it is now starting easrier after each run.

Here in New Zealand I have a SIG 4 Star 60 in which I put a NGH GT17 gas motor. It's had 5 flights & the motor is running great on a 14 x 8 prop. Plenty of grunt for aerobatics & easy on the fuel; the 180oz tank will go 25-30 mins when full. Ignition is 6v RXCEL on a NiMH 6-cell pack. Nice sound too on the stock muffler; I used some fibre gasket material to make a circular gasket where the barrel splits in two. I also had to modify the firewall to accommodate the muffler plus I put a fuel tank hatch in the model. I'll try to upload a pic from my mobile...

I still have mine and it is a great running engine. I did have trouble with the stock muffler not staying on or coming apart in flight. Get one of these mufflers from Valley View RC for a DLE-20 and all of the muffler issue just go away. Here is the link if you are interested.

Thanks for the link but it looks like that muffler will be pointing out sideways instead of down.

Yes it will but believe me this is a much better muffler. Try the stock muffler and if you can keep it together then this will not be needed. This is a option if it comes apart on you. I lost 2 stock mufflers then went to this muffler and been very happy with it.

I have a stock DLE 20 muffler I can use I forgot I had that should work right?

Yes the stock DLE muffler will work just fine. What plane are you going to put this NGH 17GT engine in?

It will be in a World Models Zero like in the first picture but i am going to do a lot of cosmetic work to the plane to make it more scale such as shortening the cowl and going with the paint scheme in the second picture. It is hard to tell from the stock picture but the cowl is about an inch to long i am going to cut an inch out in the middle use fiberglass to seem it back up and repaint.

I have built a Zero also but a larger one. If it stays true to all Zero's you'll need extra nose weight for that plane. The DLE muffler will also be a better muffler with an inverted mounted engine. Don't know how big the cowl is but I would look at the NGH 25GT engine. It is just a litter bigger engine and weigh's a little more which would mean less nose weigh needed to balance. Good Luck!

At Agape Racing & Hobby you can get a pitts muffler for the NGH 17GT and the NGH 25GT. That would look awesome on that Zero.

This one is only 60" wingspan. I am thinking of buying a 80" CMP ZERO.

I have the CMP Zero with an EME-55 engine in it for power and it fly's great. I still had to add 1lb of weight to the nose to balance the plane. If you get the CMP Zero mount your elevator & Rudder servo's in the fuselage that will same some weight. My Zero weigh's in at 20lbs 2oz. Others that have built the CMP 80" Zero weigh is around 23 to 25 lbs. Will the EME-55 engine and a Xoar 22x10 prop the plane pulls in 26lb of trust. Not bad for a 20lb plane.

I may do a build thread on the 60 size Zero.
