KMart 'Lidl' glider RC un-powered conversion - caffeine - 19-06-2023



Following on from my two successful KMart 'Big Foam Glider' conversions to powered RC planes, srl suggested an unpowered one to be air launched or towed.

I was considering a 2S battery with a BEC (I have a couple of Matek micro BECs that weigh in the order of a gram or so each) however srl suggested that a 1S battery may be sufficient.

So I took some old toy drone 500mAh 1S LiPos and plumbed them into my receiver (Matek R24-P6) along with a servo, and they worked! The receiver communicated fine and controlled the servo, even at a not-quite-charged 3.7V.

The KMart foam gliders include a big steel bolt in the nose that weighs 32g, removing that and replacing it with a battery (15g), receiver (4g) and servo (15g) would result in a very light plane. I'll add another servo or two for aileron control and a few carbon spars in appropriate locations, and the whole thing should be dramatically lighter than my powered conversions. I may even get some more 4.3g servos to use instead.
