| About the size I dont know, but the Concept VR 46 use 515mm blades so you can take and idea of the size.
If you need a bigguer tail boom you can get the Concept 60 tail boom and in case is to big you can cut it.
Also Kalt helis use the same 20mm size of tail boom, so you can get a 60 size kalt boom.
In case you need the inside drive wire Hirobo sell a Hirobo 2523-009 Tail Drive Shaft Set for around $20.oo.
This kit include the 2mm drive wire and the outer tube were the wire goes inside.........
Also Century helis use the same 20mm OD tail boom.
Good luck,
