Hi guys, thank you for all the very informative feedback its great.
Just a quick question if that’s ok tapping into your extensive servo knowledge. I recently bought several DIYMORE MG996R servos which stated a throw range of 270 degree. However when plugged into my FRSKY reciever they only move 30 degrees travel either side even with the limits set to 100% . Is it possible to increase the range to 90 degrees either side without doing modifications internally ?
@SHFX Welcome to the RobotShop Community. Assuming the servo can do 270 degrees using a pulse range between 500 and 2500us, then you might need to extend the limits to 110% or even 120% (which would mean your transmitter is set to RC standard range of ~600 to 2400us or less). We tend to verify range using a non-RC servo controller connected to a computer to ensure we know what pulse is beign sent.
I managed to increase the servo range to 170 using an Arduino so guess it is the TX. It is a cheap FLYSKY transmitter i am using and i have increased the endpoints to 120 but it makes no difference, therefore i guess it is the Pulse width.
I have a new Taranis X9D transmitter that can try but need to figure out how to convert it as it got shipped from Hong Kong by accident and i cant use it in the UK.
I was hoping to at least get 180 (90 either side) using a FLYSKY or FRSKY TX so still a bit stuck, but thank you for taking the time out of your busy day to respond, its much appreciated.
@SHFX We used to offer servo range extenders - try to look that up: they plug in between the output of the receiver and the servo and adjust the PWM output.
