Lets talk about Corona Servos....
Why spend $35.00 dollars per unit where you could get 4 for Coronas Servos DS-939MG Digital for $41.00
I have been using these servos for about a year... and I haven't had any issues with them...
very strong again Very strong...
HS 65mg has 31oz at 6 volts
DS-939MG 35Oz at 4 volts.
Warning, I use a CC BEC.
Also for 3d throws I use the Servo Arm Kit - 3D Long Arms for HS-65MG
I had it before on the Extreme Flight Edge 540 and was sold...my friend never had any issues.
I have it on my Extreme Flight Extra 300 EXP Rudder, Ailerons and on the Elevetor and I have the Hs-85mg.
any questions pls let me know.
