Hi Paul, Thanks for replying I should have deleted this an age ago. The kit went to a new owner at last years Wings and Wheels bring and buy. Thanks again Jim.

Posted by Phil Green on 08/08/2020 21:09:14: You can do it much simpler than that and for much lower cost. It looks like a simple DC motor driving a lead-screw with limit switches. Almost everything you need is already there. All you need is to be able to apply DC power in one direction (polarity) to raise them and the other polarity to lower them. The top diagram shows a simple switched reversing supply, the switch could be driven by a servo. The lower diagram shows the wiring of the limit switches. With the power in one polarity it will drive one way until the limit switch breaks. With the power reversed it will drive the other way until the other limit switch breaks. The diodes allow the return current through the 'open' switch. Arrange the motor terminals so it drives towards the appropriate limit switch, ie with pos on the left drives it towards the limit switch on the right and v.v. Your only other job is to adjust the limit switch positions if necessary.

He isn't too internet savvy to find the help you guys have given.

Hi the control cables have 3 and 4 cables. I will add pictures today.

I am looking for a control board or wiring diagram to operate a set of retracts fitted to a DB sport and scale Hurricane. The retracts operate on a screw jack system with limit switches for up and down. I think SM services may have done something like this for the LMA guy's. Any help is really appreciated.

Hi I have decided to sell off some kits and I have obviously taken the instructions out of the box and have misplaced them. I know its a long shot {really long shot} but would anyone still have a set that they would be willing to copy or sell. Hopefully Jim.

We had the same email sent to our club they wanted £875 when our treasurer replied and told who ever is behind this that our committee is only authorised to spend £300 the cheeky sods replied that would be fine. Like you say its hopefully unlikely anybody would send them money, but the bank account they wanted it paid into was marked as a BMFA account so somebody may have fallen for it.

Thanks for all the help and info guys. I have found an OS 40 la which will fit in nicely so I am going to move forward with that.

We would like to know the success; or other wise; too hI, This is a work in progress but I will use the calculations as I get closer to completing it. Regarding the veneer I did use a large syringe to force pva glue under it on the first part. This was a partial success as i ended up with far too much glue under the veneer, if i was to use a syringe again I would dilute the glue a bit . I ended up using long coffee stirrers as supplied by various nice coffee shops for the smaller parts of lifting. I just dipped them into my bottle of glue and stuffed them under the veneer and moved it around to cover the foam before weihing the veneer down with various weights. The action with the sticks is like a reversal of the procedure you sometimes see on tv of people having liposuction were instead we are forcing it back in.

I will look for the calculations, at the minute I am re-glueing the veneer back onto the foam in places. It also has a sliding plate for the elevators that I am ditching and I will use my transmitter to set it up.
