Motors & Rotors have been flying various models from the SebArt range including the SU 29 30 size, SU 29 50 size and Angel S 50 size.
The quality of these kits is very high, nicely covered and light weight construction.
Both the 50 size models have been converted to I/C power and would suit the YS 63 FS perfectly.
Kits are available as airframe only or airframe with electro pack (Hacker out runner and speed controller)
