Sorry, just got off work.

I forgot to mention that I discovered these, and have 3 of them coming through US customs as I type. The hookup is pretty straightforward and should allow Servo recoil on not only Taigen Boards but also HL 7.0's & 6.0's

The JST plug is power only, and a single black wire is the signal which can be tied into a few different ports that detects the cannon shot. If anyone is interested I can post a video of it in action once a get them and mess around with it.

It would be nice to have a review of these posted. The more options that can be used with the basic systems the better.

Roger that

I think it would be most helpful great idea thanks Zip!!!

Okay. Do you need a 7.1 transmitter to operate the 7.1 receiver? Or is it possible to just use the 7.0 transmitter for the 7.1 receiver?

No, yes.

Looks good👍👍

Have you tried using this circuit board to control barrel elevation?

No sir. I dont think that would work, I could very well be wrong on this. However, they do make such a circuit that does both for a few more $$. Same website.

[SoCalBobS]

Thanks, didn't think so, but it never hurts to ask.

does anyone know what k1 k2 is about on 7.1 board they look like round silver things dont seem to be able to do any thing with them ?

There not going to do anything unless your using Servo's for elevation & recoil.

so what do they do if i am ?

Do you have a url link to these optional add-on servos to purchase them as I have not seen them anywhere available for purchase. And is there some instructional video available on the installation somewhere?

Toucan hobbies on EBay sales them or just Google HengLong servo recoil.

I have been looking for it for a long time too. I look at all the "Henglong Metal Recoil Barrel BB Unit" offered by Toucan Hobby both at ebay and at AliExpress. None of them mention servo recoil. Many of them list TK7.0 in their title which led me to think servo recoil barrel is not yet on the market.

On the other hand, Zipper does connect his cannon to a servo add-on to a TK-7.0. May be he can help identify which barrel recoil unit has servo recoil build-in.

I looked at all the Heng Long barrel recoil BB unit I can find. I can only see 2-pin JST connector for the recoil motor. No HL unit has the 3-pin servo connector yet.

Dumb recoil motor can be connected to TK-7.0 directly. Disabling the servo feedback to connect to TK-7.0 is not difficult. Replacing the recoil motor with a servo is the real challenge.

Zipper, do you use a custom built servo recoil?

[keilau]

I finally found some Heng Long servo recoil retrofit kit at ebay. They are as expensive as my plastic version Sherman shipped. For now, I have to decide whether to get the motorized metal barrel recoil kit at reasonable prices or wait. I may just do that for less than $40, not bad for the BB shooting repair plus barrel recoil upgrade. Not sure that the servo recoil is worth it for now.

Yes sir. I have also used the Metal version in the previous post...The metal version is FAR superior to the 3D printed one from Clark (which is complete crap). I have videos on my Channel showing exacty how to make a cheap & inexpensive servo recoil system. OF course it goes without saying a recoiling barrel to start with is needed. Otherwise a crap ton of custom modificatons are needed that I decline to get involved with.
