As these things tend to do, the stakes have been raised to get a reasonable combination of traction & range. There was a partial hexogrid tire which proved too soft for the cost.

Because it takes so much more material to make a flat tread stiff enough, the decision was made to go back to a PETG hub with a thin TPU tire. This would limit the compression if the tire completely compressed. Helas, PETG is noticeably heavier than PLA, despite its heat resistance. It could probably get away with PLA since the motors rarely get flaming hot. The biggest weight savings may be abandoning the hexogrid. Like the SpaceX logo & the isogrid, sometimes you just want it to look good.

The lion kingdom has evolved its 3D printing game to the point of making the thinnest possible lines & planes with the thickest possible layers. The .4mm nozzle can print a .5mm wide line but takes forever. The .8mm nozzle can print a .9mm wide line but is much faster.

Since the tires slip around the hub, there's still a dream of bolting the tires to the motors, but they now have to transfer force a lot farther across a much bigger hub. A 7 hour tire with webbing had good compliance, transferred rotation to the motor, but easily slipped sideways. It would need some kind of adhesive, whether it bolted to the motor, if the hub clamped it as before, or if it clamped around the hub. It might as well be a plain cylinder.

This repair was done without filler or cutting in to the skin, and then I added the two tone blue paint to the tips for the customer. Beautiful sailplane!

This is my custom carbon Renegade #7 I bagged with 3/16 tip dihedral and tubed ailerons making this the only Renegade I've seen with actual poly dihedral (very mild) but poly just the same. It also used to be V-tail, but I converted it back feeling it looked and flew best with the stock tails, but it was part of a test bed of experiments when I was 2nd. Owner of CR. Just had to check !

My 1st carbon Renegade,2nd race at Davenport ISR .After someone stepped on my Raider...I had to race this as my backup.hahaha finished 8th. Ok for 60" in open class! Notice the lead taped on top of the wing to get to max allowable ballast. Not exactly legal but they were flexible on the rules so I didn't cry on the 7 hour drive home.
