Help with HiTec Laser 6 transmitter request

Friends:

Which channels on a HiTec Laser 6 transmitter correspond to which channels on a HiTec HFD-08RD receiver?

Can someone recommend a source for learning this type of Rx/Tx interfacing? The manuals that come with the HiTec Laser 6 are devoid of information!

I’m trying to drive a 2 motor controller via this R/C and would like to know how to get the transmitter to do what I want on the receiver. (Which channels to use, etc.)

Thanks amigos.

If you have the equipment, I’d think some simple testing would provide the answers. Send on a channel and see which receiver out channel responds.

(on right joystick)CH1 = up CH2 = down (on left joystick)CH3 = up CH4 = down (on left Switch) CH5 (on right knob) CH6

CH8 is optional for a 6v battery, unless your using the MC to provide its power via its BEC.

Everything should be correct though CH5 and Ch6 may be switched around. make sure to check.

Thank you Joe and Zoomcat.

Both of you are right, its just that I was frustrated yesterday with the lame HiTec documentation that came with the transmitter (No channel info). The receiver likewise had NO documentation (I had to measure the voltage off the battery back to figure out it needed 6VDC), then I did some searching on the net to realize it has a broad range of voltage. Next came the plugs. The HiTec plug in area uses some really narrow plugs so I couldnt use servo extender cables, and instead had to make my own jumper cables. Oh well, all in the path of learning this robotics addiction.

Can you all suggest links or books to get up to speed on this stuff? (ex: I had airplane crystals for my rover until I did some research and figured it out) Surely all of this basic stuff must be explained out somewhere.

Do you guys know where to get Futaba or HiTec type connector supplies at a decent price? Some I’ve seen are $3 + each ! Some sell complete cables at near this price. I’d rather make my own.

Thanks guys,

Zoomcat:

Can you clarify Channels 5, 6 and 7 please?

Thanks,

Migs

Channel 5 is the retract switch on the top left.
Channel 6 is the flap-rate knob on the top right.
Channel 7 and 8 are unused because it’s only a 6 channel Tx.
Channel 8 is marked as also being the battery input but you can use any of the channels for that if you are using a receiver battery pack.

ya, I did get the channels right. Thx for clarifying that Evo.

Thanks evolution!

All the best everyone, and have an awesome Christmas! - Migs

Amigos:

I have comms working with the Laser 6 and the robot with a HiTec receiver, and channels 1 and 2 connected to the sabertooth. It seems to work, but a forward motion is achieved with a diagonal push of the stick (not a straight up push). Do you guys know how to make forward be an upward push of the stick? Likewise, all the robot motions are rotated on the joystick. Is this common?

What dip switch settings would you set on the sabertooth?

Thanks amigos-Migs

You need to switch dip switch #1 to on. You are on differential controls right now. You want mixed mode.
Switch Dip switch 1 and your problem will be solved.

Hi evolution:

Your advice worked perfectly, but there is one more thing:

My dips are 1 on, 2 off, 3 on, 4 on, 5 on 6 on

The Tx joystick goes left and right as expected with analogous motions on the robot, but front and reverse are reversed. That is, pushing forward on the joystick makes the bot go straight back and pulling on the joystick makes the robot go straight forward. Any ideas?

Most grateful for your previous advice!

You can reverse the servo channel on the radio to fix this.

Hi Jim:

And this reversal would be where on my Laser 6 Tx? Remember, I’m a newbie at RC.

Thanks in advance!

Remove the battery cover.
