I'm looking for a linear actuator with a 12 volt or 24 drive but interfaces with a 4.8-6.0 volt RC receiver. It must have pretty much 100% duty cycle and have 35 lbs pulling force.

The actuator is needed for hand brake operator of a track vehicle that I want to modify into remote control. I'm using a Fatuba 9 channel radio and Futuba receiver. I am also using CK designs actuators for the throttle and shut down actuator. They utilize the same set up I need with receiver voltage input but run off 12 volts for the actual motor current. Problem is I can't find an actuator that fits my need. Servo City has a smaller one (20 lbs) and a larger one (100 lbs) and has not been responsive to my phone calls and e-mails. CK designs has been totally unresponsive to e-mails and does not list a phone number. Can anyone tell me of a responsive vendor with a good product that fits my needs?

 

I recently used a bunch of Linak LA12 actuators
These are available in three different thrust ranges 200, 300 & 750 N 12 or 24V for about US$150.

I think you just need the basic model without electronics. To control use 2 x 2 pole relays, forward & reverse www.linak-us.com or www.linak.ca
