New ZDZ112 B2RV / Installation into PAU Edge 540

Need to get some real work done today but wanted to bolt the mufflers on quick since I was set up for that when I quit last night.

I used some 600 degree silicone from McMaster Carr and also used the stock DLE gaskets. Why did I use both? The flange on the heads of the engine are not overly wide and I did not want silicone alone to blow out eventually. Also the gaskets are re-usable then because they don't stick to anything and peal apart. Never had one leak, so I guess it works.

Also a note USE THE MUFFLER BOLTS THAT COME WITH THE ENGINE (or exact replacements)!! They are high grade and also the correct length since the threads in the heads are blind tapped if you use bolts that are too long you will strip the heads!

OK, last tip. I use Nord Locks on all my muffler bolts and prop bolts. Again, never have a loose muffler since then. I get the stainless ones that have a little smaller O.D. from mcmaster carr and they fit inside most muffler bolt holes.

Is that a choke servo?

Is that a choke servo?

Yup, rear carb. Did not feel like messing with a bell crank, linkages, etc.

Forgive me. I was a little shocked. Plus I like the icons and I need to increase my post count...

Looks good! I like the Yellow too!! I am working on my edge this week. Hope to debut it Labor day weekend down in MS>

Looking good Terry, are you bringing it to the BH Huck?

Looking good Terry, are you bringing it to the BH Huck?

Probably not, but we'll see how much run time I get on it first.

Found a few more hours tonight and knocked out some final details. Seems odd, but all that is left is the landing gear, tail wheel and canopy shell!! I kinda worked bass-ackwards from my normal build. The build stand has been amazing so far to assemble without actually handling the fuse or plane at all other than to flip upside down now and again.

So tonight I......
- Rudder push rod and setup.
- Ignition mounted.
- Cut the cowl - when the mufflers that are in prototype stage come out I'll probably order a new cowl, so for now I picked the best performance option out of what I had on hand with the Jtec DA100 mufflers.
- Baffles = I LOVE CREATIVE FOAM!!!! For goodness sake baffle your engines if you don't already!!! They will thank you!! This took me less than half hour and every bit of air that comes in is passing though the fins, should run very cool.
- Set up choke servo, set max travel limits and set end points with an amp meter. I have it on a momentary switch and slowed the servo to .8 seconds to full travel to basically widen the dead band width so that there is no chance of binding.
- Set up throttle servo
- Re-bind to reset the fail-safe so I don't inadvertently burn up a choke or throttle servo

This thing will most likely run tomorrow night, we'll see about maiden this weekend. I have a fun fly on Saturday and it's not the place for a maiden flight. Perhaps on Sunday......fingers crossed.

You never cease to amaze me, Terry!
