Hello,
It appears to me like Savox has interesting line of Digital servos that can feet for 2m Pattern ship.

for Ailerons: SC_1251MG (9kg, 0.09speed, Weight:44gram!!!)
for Rudder: SC_1258TG (12kg, 0.08speed, Weight:53gram!!!)
for Dual Elevator SH-1350 (4.6kg, 0.11speed, Weight:26gram!!!)

All Coreless, Digital with Dual ball bearing etc.... (Main shaft Futaba compatible...)

I have no experience with Savox products and I will appreciate any comments

Regards
Amram Leshed
