On 23 May 1958 P.Z.L. flew the prototype of a two-seat semi-aerobatic light monoplane to which it allocated the designation P.Z.L. 102, later giving it the name Kos (blackbird). Of all-metal construction, except for fabric-covered tail control surfaces, this had fixed tailwheel landing gear, seated two side-by-side in an enclosed cockpit and, as first flown, was powered by a 48kW (65-hp) Nar-kiewicz WN-1 flat-four engine. Further prototypes preceded the production P.Z.L. 102B flown first in October 1959, which was powered by a Continental C90-12F engine, and the type was built in moderate numbers before production ended in 1964.

| Anthony, antspence(@)telkomsa.net, 30.11.2007 Jeff I would love to chat to you somemore about UDI and is there any possibility that I could buy those manuals off you.my e-mail is antspence@telkomsa.net | | Anthony, antspence(@)telkomsa.net, 30.11.2007 Thanks Jeff that is a great help, appreciate it. i am just finishing off a top overhaul on it. | | Jeff Benater, Network(@)pixie.co.za, 10.11.2007 Hi - I used to own ZS-UDI which I sold to an SAA Captain-Named Donaldson about 25 years ago - I kept it at Half Way House- the altitude was 6500 ft. The Problem and danger on taking off was to keep the stick slightly forward on take off- otherwise it tended to stall - and one of the of the captains that "Knew All" dipped the right wing into the ground.It is not very Aerobatic and to to a loop you really have to get the speed up in a dive first and pull up and be sharp about the manouver As for rolls, Dive till you get quite max speed ,pull up stick left or right and just before you complete the roll --"opposite rudder completely- just before you get to 270 full opposite and the and then centralize just before you get to 360"- It was never good arobatic machine,at that altitude- I always considered it an unsafe machine and not for the average pilot ==I still have a few manuals Spins were no problem but not more than 2 rotations
I bought the machine from Joe shatz in those days - he had it at barag G - very few pilots wanted to fly it -However my friend Skully Levine and myself managed to master it
an underpowered machine for the highvelt -- coast should be much better
Jeff Benater | | Anthony, antspence(@)telkomsa.net, 12.09.2007 I own one of these aircraft. ZS-UDI and would like to know from anyone who has experiance with the type, just how aerobatic is this aircraft and what is it's "G" loading, as all my books are in polish. |
