Creating a moving machinegun

[Herr Dr. Professor]

Mindstorm: no doubt you have already seen from Imcq11's build (to which Jofaur86 refers) that Louis is a genius at these things. I have been astounded at his builds for some years now. He does use the HengLong TK7.1, which has all kinds of great functional capacities (except for a limited sound array). But I believe there may be the capacity in your HengLong 7.0 to add one servo which would give you the chance to create a moving machine gun and the gun flash, although these may have to be controlled by separate switches. I hope someone reading this will confirm whether of not I am correct, and if I have it right, explain how to set up a servo using the HengLong TK7.1 and its transmitter. I'm cheering for you all the way (and, of course, ready to snitch ideas, too).

Thx, i havent given up yet, but indeed plans need to be altered, the HL7.0 board has an unused option on the Panther, its for the rear lights, which (as u probably know) can be (fairly easily) turned on and off from the remote.
Expecting the motor to arrive in the mail today, ill let you know if that works.

Hello, is there a solution to install a servo? At one time HL had a small module, powered with 5 volts input, and an output for servo, all functioning by applying + 5 volts to another input? personally used on a Tamiya tank, but will always remain the percentage of lateral movement, simple to adjust with a radio, programmable, but in your case? I still don't see how you are going to achieve this with a motor? but as "Her Professor" maybe there is a solution? I will follow this carefully, being curious by nature

[Jofaur86]

Here is what I was talking about, servo adaptation plate, cannon recoil, used certain HL tanks firing balls

connection, just send a pulse + 5 volts to the S (Switch, or other buttons)

I think you overestimate my understanding of mechanics and electronics, im just a simple man, the design i have in mind is like the ones in this video:
https://youtube.com/shorts/PP8VB6CCqjw? ... z0mvac2H7N

Where a rotating motor will create a continuous left-right “mowing” movement.

This design fits with my idea of using a system to turn something on, have continuous movement, untill turned off. (Like the powerflow i get when pressing the fire button on the remote, but which i cant use because the HL mainboard gives a signal on-off-on-off-on-off etc to the MG led.)

Thats why i figured using the rearlights led connection, because they can be turned on and off separately independent of the front lights. (The HL panther doesnt have rearlights)

[Mindstorm]

So connecting the new motor to rear-light led connector didnt work, i guess its too low current (i tested the motor on a 1,5v AA battery and it worked fine)

I could disconnect the smoke motor and use that, as that is easily turned on and off from the remote aswell, and should have enough current.

[Ecam]

I know the smoker port will be sufficient. Not that surprising the light port didn't work as the LEDs require so little power. If you are like me and pull the smokers anyway, that would be a great choice. You might consider a link that is springy between the motor and MG (so it could flex and not damage parts).

Here are two videos of the mechanics:

Thx,for your interest

[Herr Dr. Professor]

Well that's pretty nifty! You see, you are moving toward electronics wizardry, one little step at a time. With the next step, you'll be ahead of me!

[Mindstorm]

Hah, i highly doubt that, buy thanks for the kind words
