JR servo's 4021
Hin On my way to work one morning I spotted this wing in some trash that was being discarded..In the wing were 2 JR 4021 servo's.. I can't fine any information regarding these servo's.
Question #1 Can they be used with Futuba gear..
(that's all I have)
#2 Where can I find any information on them.
#3 What is the best to check them and may sure they
are working like they should
I fly mostly 40 size planes.
Thanks Dan
