Construction and operation

The Pushpak was a high-wing braced monoplane with a fixed tailwheel landing gear.[1] The fuselage was built from metal tubing, the wing aluminum ribs on a wooden spar, all covered in fabric.[1] The Pushpak first flew on 28 September 1958 and was powered by a 90 hp (67 kW) Continental flat-four engine.[1]

Around 160 aircraft were produced for Indian flying clubs for use as basic trainers.[1] Two examples were gifted to Malaysia and were later sold to private pilot owners in the United Kingdom. These examples remained in active operation in 2013.[2]

gollark: This was useful once when a draconic reactor explosion accidentally destroyed the entire spawn area on one server I was on, but the storage stuff had a dedicated spatial IO unit and could be sent to a backup site in the End.
gollark: GTech™ standard policy is to have the main ME controller/storage/crafting CPU stuff in one area and then run a bunch of wires out for machinery.
gollark: You get more side-product outputs for slightly more power/processing time.
gollark: Consider auxiliary sieves though. They're basically free apart from needing somewhat more pulverizers and power.
gollark: I guess if you're not really bottlenecked by ore input it's fine either way.
