PAU 36% Edge 540 Build

I have cut the cowl ring, but the cowling won't fit over the DA100 and up over the mufflers sticking down.

I know that Hervey and Ken are in Bellingham today flying at Bellair. Not sure when they will see this. Wish I could give you some better help.....

I'm actually wondering if they cut off 1/2 inch or so of the mufflers to make them shorter and fit within the cowling. The problem is just getting the cowling over the mufflers so they can stick down through the holes that I cut for them. With the size of the DA100, you can't really turn or adjust the cowling because it rubs against the sides of the motor.

[Dan767]

I believe they did. Not 100% on that....

I have canisters as well, so I can't help you either. I know in my Ultimate, I had to make the holes for the mufflers (TMB compact) an oval shape, not sure if that is what they did or not. I will browse for some photos of thier planes.

Evidently cutting the mufflers was not the answer either. I cut about 3/4 inch from each pipe and still cannot move the cowling around and over the mufflers. If I cut any more off, they won't stick out below the cowling.

I may just give up on that ##%%$ thing and buy canisters.
Also, just order a new cowl with only the back airflow hole cut out.

If I go with the canisters, what are you all using? Also what headers are you using and what drop?
Thanks.

Here is a photo that kind of shows what your looking for. http://www.flyinggiants.com/forums/a...022-x-659-.jpg found on page 12 post 135 in this thread.

Page 27 post 319 give some info on a drop for a header if you are going to go with cans.

Hope all these helped you out.

For canisters, I have a DL100 mounted in mine, so I bought a set of DL cans that they use on the DL50's. The headers that come with them do not fit (made for the 50's), so I bought a set of DA flex headers. The cans are very light but with that are fairly thin. So far I got about 10 flights before one can lost the back end, it was replaced under warrenty. Got about 4 more flights so far after changing the one can (14 total flights this year). I really like the way the plane handles and looks. I have been practising the Basic IMAC sequence with it, which is hard enough for me to do. Everyone at the local field likes the looks and how it handles while flying, it make me look good. LOL.

I think I might have found something. On the build thread from RCUniverse, someone else who put on the compact mufflers cut 1" inch from the stacks and that seemed to fit. I took off about 1" inch and it barely fits with a little adjustment. I think I may be able to make this work now. Now just to finish all the work up front to make sure I have everything ready to install the cowling, since it is not exactly an easy job putting the cowling on and taking it off.

Glad you found something that worked for you. It is never any fun taking off and putting the cowl back on.
Let us see what you had done by posting some photos if you can.

Tkapfer,

I am away from my desk, at a fly-in in as Dan mentioned, so I cannot take pictures of mine today.
I did cut about 1" off of the compact DA mufflers to make it fit.
Once you get the hang of it, it is not that tough to get the cowl on or off the plane.
Please email me if you still need pictures when I get back on Monday.
John VH and Astrohog also have the same set up, but we are all at the same fly-in this week-end (lots of fun!). They may get a picture for you sooner than I can.
