*Update 20-02-2022 - now a variant with a stronger foot, as the first design was a little fragile* Designed this battery tray, which replaces the existing servo mount. This allows for bigger Lipos to be installed, above the servo. (This does raise the COG somewhat). I've run it with Turnigy 2S 1300mAh lipo, and the Ovonic 2200mAh AIR lipo also fits! https://www.ampow.com/products/ovonic-7-4v-2200mah-2s-35c-short-lipo-battery-with-deans-2pcs?variant=39435482235036 Currently two packs for only 14 euro's. 2200mAh is more than double the capacity of the original battery, and should give a very long run time. I've been using the stock lipo strap. Printing: I recommend printing it on its side, which doesn't use very much supports. This gives the best strength on the thin foot.
