Wing riggers 4 axis remote controlled

Want a remote controlled 4 axis wing rigger, locally made. The one pictured has a buyer already. I will make more as required during the coming winter.
The two wing retaining cuffs are pictured are for a Nimbus 2 and a Mini Nimbus, I will make other glider model retaining cuffs as required.
The rigger comes in 3 parts, the wing cuff, the retaining keeper and the bottom section with the rams, battery, wheels
All parts etch primed epoxy painted. Some may query the lunchbox for the electronics, tests showed that commercial boxes block the RF from the remote.
An initial run of 3 units will be done, more if ordered. Once built they will be at Christchurch
Once you decide a $500 deposit will be required before construction starts mid June.
