Need a replacement muffler for my 81hp A1. The exhaust pipe welds to the muffler are broken.

I’m wondering if anyone has attempted to upgrade an A1 stick grip to the C1 style with built in trim switch? From what I can tell the only difference is 2 relays and the stick grip. I believe the grip is nearly identical other than the top switch. Diamond has a service bulletin for the early C1’s bu...

FlyQ is great if your flying in the US. I bought a lifetime subscription for $500 a few years ago.
1. Intuitive
2. Easy to use in flight
3. Integrates with Stratux, Uavionics, etc.

They also offer (or used to) a free subscription for CFI’s

After disconnecting both ailerons from the bell crank, the friction seems to be isolated to the aileron controls inside the fuselage. 1. Right control stick pushrod rod end bearing is nearly frozen. 2. Nylock was very tight connecting bell crank to aileron push rods. This is the connection under the...

Thanks guys! Hopefully I can get this annual completed soon. My katana has been very reliable for 5 years. First issues I have had were this year.
