1/16 Flak 36 88mm

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

Well, someone has to do it!! :/

Some of them yes, others might be more difficult. I cannot begin to think how IR guys will hide the wires, but they can worry about that.
The recoil and elevation wiring may hide down inside, but there is no slip ring installed here, so caution will have to be used upon installation.
Will have better idea when i get the first prototype fully operational :)

Sneak peak, 2channel test only at this time
phpBB [video]

The next 88 i build will have recoil upgrades aswell, for now this will keep as the initial test mule and go with an AA setup we have planned
Yes the servos are not smooth, i will work on that, there are no limits set, its just me checking it for movement and play.
I am well pleased with it and its a beast :)

Haha, i have to say i didn't even try to run full speed stick controls, but there is time for that next weekend. It has rapid movement.

Planning on setting up 2 or 3 of these running off a new generator we have on the build queue and running multi searchlights connected with a radio truck. then the central control unit will run servos for all guns & lights and move together!

Sounds like a fantastic plan. It would certainly provide a great focal point for an exhibition display.

as well as being too fast, the movements are jerky. The servo in sight is unwatchable .....

I am sure we would all be very pleased to see your version especially as this is a work in progress/Prototype.

When I write it is because I have already faced this problems and solved them. You can see three years of work in this thread (maybe you had missed it :) )

viewtopic.php?f=23&t=27595

It took me more than a month of my time to get to this result:



this was much simpler:



the final result:



I love to present my WIPs when I have solved problems, showing a path that others can take

She has already, just fettling it to be sure before we make any more.
Have to say we have enjoyed taking it for a run today.
Cat & the kids have all had a go and I have to say I was ultra impressed when Cat reversed the flak with apparent ease and both the kids picked up the rear steering straight away.
Looks like I need to make myself another model for myself, I can see I have lost this one.
May aswell get on with the Flak40 at some point :)

I expect this will already be within your field of knowledge, but just in case I thought I would post it anyway. Watching the video of the 88 in action, some of the movements are a little violent. I have come across this https://modelradioworkshop.co.uk/shop/s ... ervo-slow/ It is adjustable up to 15 seconds.

Thanks for the post, we have seen those also.
The latest video we just changed the pivot arm lengths on the servo and then used the channels with pots on the flysky fsi16x transmitter turning them by hand.
To be fair the notchy movements are now down to servo resolution and you can see at some angles this can lead to a non smooth movement.
I am sure a higher grade servo could help greatly but just helps increase the price.
I just wish I could do electronics and setup with geared motors and arduino etc, but that stuff is beyond me.
It's like everything, everything could be made better. :)
So further changes may occur with time
