Mode Zero

What amount of throw is required - (say in degrees)?

Dunno but if you copy the geometry from the pics Rich, mine does twinkle rolls and its really very responsive which is how I like my gliders, needs very little stick movement in normal flight. Shaun has flown mine, he'll confirm its really snappy







30mm and 65mm for me:

With hindsight, I put the 'spar' (pivot axle) too far back on my Lidl wingeron, and the place where the control rod to the servo entered the wing a little too far forward. I test flew it and it was controllable but even with the transmitter throws maxed out it was not very responsive. Rather than remake the wing pivots, I just fabricated some extra-long servo arms by cutting one long arm off a servo and fastening it on to the end of the other long arm. I now get slightly more wing travel than is shown in Phil's video.

Mine are nearer 35mm and 100mm
You can see the original position where the control rod went in near the wing leading edge, and the cutout in the wing stub to give clearance. With the longer servo arms, I also made some new links that fit into the wing further back, so those cutouts are no longer used - the clearance cutout is now in the wing panel rather than the wing stub.

Thanks for the info guys - that's more than I need to get started - will post some pics when done.

Spotted at our patch today. LIDL Twin. 2x 100W motors. Goes like stink ! Conventional Ailerons and Elevator. No rudder but differential throttle instead (subject to ongoing experimentation)

A man after my own heart, BUT, Damn - he beat me to it

I'd envisaged my "variant" to have a T-tail, like the full size Bronco. Ah well, maybe one day

Aussie folks can get the Lidl glider (if its not out of the same Chinese factory I’ll be amazed!! ) from K-Mart for $10

Also available in NZ from K-Mart but I don't have link details. Thanks for the "heads up" Barry

I've ordered 4, currently in transit. It'll be good to try some of the conversations you UK types have experimented with. Also, I can do a direct comparison with the Banggood Cheetah.

On the wingeron version I put the hooks and bands on the TE - rather than where Phil had them on the underneath of the tubes - so closest to centre of rotation

I thought bands on TE might generate less drag

The elastic band is fairly loose and has worked well over time - no idea if it's any better!


Also tried a 3d print on another Lidl - cut wing in half and printed section goes in between so larger span by couple of inches

Lots of versions on Thingiverse - both for old and new Lidl versions

This one - https://www.thingiverse.com/thing:6455925

but can't remember which one I actually used

Came out slightly heavier than a straight hack but has worked well
