Hey Kevin,

That is so much better than that crappy stock recoil unit. The gun barrel has come back from my mate now and has been drilled through so i can now paint it and fit in the flash led. I've gone for a 5mm led with a narrow band so the bulk of the flash can be seen forward, have tested it and it looks good

Cheers for now,

Mark

Hi there.

I have an Rx13/airsoft gun equipped S&S HL Tiger 1.

If I modify the gun into a recoil unit by gutting it and
modifiying it as you have with a servo,what would I need to make it
function as a recoil unit please.

Also,would the ARTC unit work with the Rx13 board please.

Cheers,Mark

Hi Mark

My first bit of advice would be to get yourself a RX18 board. These are very cheap. The ATRC may work with a RX13 BUT the board layout is different and I can not tell you which pin you would need to solder the signal wire to.

To utilise a servo for your recoil you would need to either get a ATRC MKII board which has a servo output
OR
Upgrade your radio system to true Hobby Grade 2.4gHz
You can then use either a RC2HL adapter or SGS or EL Mod unit to control your tank and a programmable radio transmitter like the Turnigy 9X to control your servo.

Cheers

Hi Kevin,

thanks for that info,unfortunatley,neither is an option.
SWMBO is the financial controller in our house(aren't most wives )
and sees money spent on "playthings" as money wasted,so I tend to
work with what I have and do it for cheaps .

Would you check the track recoil thread please?

I have something that you might be interested in for the Rx13.

Mark

this looks awesome and a great tutorial

I have a heng Long Panther G and want to put a barrel recoil in it. This looks like the best option. Do the HL recoils also fit in the panther turret? or are there people here whit recoil in their panther?

Hey Paulus

Yes the Heng Long units fit in all of the Heng Long tanks. The problem with the Panther is that you really do have to buy an after market barrel. It is a tough job trying to make a BB firing barrel into a recoiling one.

I am only taking about the barrel - the recoil unit itself is just as easy as any other tank.

Cheers

Hey All

As stated earlier in this thread this mod can also be done with the BB gun unit as well since the two unit function similarly. However, I have not posted any pics or instructions for the BB gun mod. It is pretty simple and I think many have been able to work it out by themsleves. Regardless, one day I'll get round to it in more depth but till then here are some pics of the BB unit modded for recoil.

As you can see the BB unit is a bit 'fatter' than the recoil unit. Hence to have the servo arm swing in the centreline of the barrel the servo can be mounted on the bottom of the unit rather than on the side.

You can also see a method of attaching the block inside the BB unit with the barrel. You can use some shrink tube to attach the barrel to the protruding nipple on the block inside. In the pic above the shrink tube is red. Depending on the tank and barrel used you can even cut the shrink tube to a certain length to make fine adjustment of the barrel length.
