New Hitec HS-7990TH "ME" Magnetic Encoder 12 bit servo

[TX Newbee]

Are they the same size as the Futaba 5050. I'm curious because I'm thinking about options for powering the Rudder on Bob's LW 55% / AeroTech Extra 260.

My options are:

1. 2 7990TH Durant Direct Drive in Rudder if the plane will balance with the weight that far back
2. 2) 7990TH in a SWB Tray Pull Pull
3. 1) Seiko S-50 Servo

Thoughts?

Well the 7990th are only 10% bigger according to Mike. So if you were to sand the insides of the servo box walls installed in the plane i would think they would fit. If it was my new 55% I would go for the durant direct drive.

The 5050's are similar in size to our 7945 which are now pretty much delegated for 1:5th cars. We also have the new 5805MG which is even bigger.

The 7990 is just slightly larger than the current "standard" size servos but still offers over twice the torque of the big servos that are twice the weight.

Mike,

Magnetic encoder modules offer non-contact alternative to potentiometers.

A picture of one is attached, not the same one used for servos, but basic principle.

Cool stuff Hitec!!!

Should have gone with a turbo encabulator!

Yes, it is possible that we could use them in standard sized servos in the future.

Here's a pic.

Man Hitec just keeps coming out with new stuff and is pushing technology. Cant wait to give the new tail servo. Mike can the new tail servo handle 6.0 volts?

This is from the servo 7990 servo or just a random pic?

Mike,

Outstanding continuation of what we know Hitec is capable of..............."CUTTING EDGE PRODUCTS"............others choose to follow when forced to do so!

I got a chance to talk with Hitec at this years government UAV conference in Washington DC and learned about the magnetic encoders but assumed they were just for high end robotic applications. Great job Hitec on bringing this new technology to the hobby world! no more potentiometer wear!

This is the actual M.E. from the 7990 sample we have.

Mike, Please! Is there any kind of estimated release date for this bad boy - HS-7990TH?
And one for the Hitec suggestion box… Since a lot of us are now running 7.4v Unregulated Two cell LiPo systems and, it looks like it’s all headed that way. I would like to see a relatively low cost, Low to Medium Torque, Digital, High Volt Servo to operate Throttle, Choke and other applications that do not require a massive servo. It’s kind of a bummer to have to regulate part of your system or have to equip your Throttle & Choke with $100.00+ Servos. Any Thoughts?
Thanks!
Paul…
