Just one question, some having problems keeping the muffler tight on the engine .What are those that have overcome this problem done to fix it?Friend of mine has even gone to the length of fitting Heli-coils ,but is still having problems.
I am interested to hear how the Nordlock washers work on the muffler. I am using them on the engine stand-offs and they are working quite well.
I am using a header pipe and they kept loosening as well. Because the aluminum header material is relatively soft - and the contact area small - the Nordlocks were not a viable solution. I ended up drilling the bolt heads and made a ''clip'' from 5/64'' piano wire, and the bolts have held fine since. It should be even easier to do this with the Pitts muffler by making the piano wire in a bracket [ shape, inserting it through the SCHS bolt heads and bending it a little.
This is a clever idea, why not just safety wire these also? You've done the hard part-drilling out the bolt heads.
I switched props to Mejzlik 18X6 on stock muffler. I got 9200 RPMs on the ground. Was flying great until I had a radio cliche. I had no control until about 3 ft from the deck, slammed through a huge tumbeweed and amazingly recovered!!! I flew it back about 75 yards and landed her like a B-17 coming back from a mission over Berlin. HOLY@$#%!!
She took some flack horizontals,elevator, left wing, flap and aileron required complete recovering. The good news, the Giant Stick airframe is good to go. THis is one RUGGID model!
The Syssa stayed running and helped me save the plane.
