Please tell me where I can buy a balancing jig as you have. That is impressive.

Speaking of Adverrun, can anyone give me some guidance as to where I can buy the 2x2mm screws for the spinner to backplate assembly.

Thanks checho4. The screws you suggested do NOT fit the Adverrun CD spinners. These Falcon screws are 5x2mm and are too long and besides that, the threads are different. Thanks again, at least you tried.

Hi,

Falcon spinner screws are M2.5x6 .

M2 size screws are widely available, however 2 mm long ones are quite special. You may need to get longer screws and shorten them e.g. with Dremel.
In the US metric screws are not that common but you find M2 screws in well equipped hobby shops selling RC helicopters like Amain Hobbies or Anything Heli. Lynx has M2x3 button head screws, but availability in the US could be poor.

Hi ini, I appreciate your response. You have provided more accurate information and guidance as to where I might be able to buy them. Thank you.

Hey, You´re welcome!

Something that struck my mind is that the AVR screw might also be M2.2 . That is actually a relatively common thread size too.
You should check the thread outer diameter with a caliper to be sure. In metric threads the nomination comes from outer diameter & pitch, e.g. M8x1 (where 8 is outer diameter and 1 is pitch in mm´s). In standard threads (not fine etc.) pitch is omitted. To make make a little less clear the screws are described by thread x length (e.g M5x20). The outer diameter is normally sligthly less than nominal value (0-5 % less).

Some servo screws may also be suitable for your needs. Esp. KST micro servos have M2.2 screws.
In the first picture you will see 2 Falcon spinner screws (M2.5x6), 3 KST servo screws (M2.2x5) and a single M2x5 screw.
In the second pic there is a Robbe servo accessories bag with 2 M2x5 screws.

Hi again ini. Your above recommendations have really opened up my choices. Next I will carefully recheck the measurements of the screws with my digital caliper and narrow down my search. I felt certain these sizes were available somewhere but, the search is not always easy. Thanks again.

BTW guys, I apologize for hijacking this BJCraft Epilogue thread. I noticed the use of an Adverrun unit and jumped right in.....Sorry.

I started with 0.7° wing incidence, relative to the Stab
I decided to increase to 0.9° for tail attitude
Easy task to be accurate with CK AERO - BRYAN HEBERT tools
Problem now, I have to adjust the down thrust ...
I will check the CG too, after the chat I had with BJ
My initial CG was in fact too far back
240 to 245 mm seems to be an optimum CG with a wing incidence close to 1°
