Wilga PZL-104 – Aircraft of the month

This aircraft of the month is the Wilga

https://en.wikipedia.org/wiki/PZL-104_Wilga

Like the J-1B Don Quixote, the Wilga was made in Poland with some very creative engineering.

While not as common of a Bush Plane as a “Cub” its a very capable machine, packed with unique design features.

Designed in the early 60’s it was originally powered by Ivchenko AI-14 Radial Engine Produced in the Ukrain

The Wilga 2000 was a late 90’s / early 2000’s IO-540 Lycoming powered version.

The first time I saw one in person was at Oshkosh 06′

No modern story of the Wilga would be complete with out coverage of the Draco Wilga a P&W PT6A Turbo prop powered monster bush plane created by Mike Patey.

If your into Homebuilt aircraft construction and flying I would highly recommend you check out Mike’s YouTube Channel.

For the RC / scratch builder group Outerzone has 2 options for plans

55″ electric powered version from 2005

There is also a 36″ free flight version from 1973 that could easily be converted to Electric / RC

 

 

 

Dyke Delta – Aircraft of the month

The Dyke Delta was designed and built by John Dyke and first flew in 1966.

They do show up often at Airventure and SNF to help breakup the conformity of RV’s.

An excellent write up on the history of the aircraft can be found on the EAA web site, written by Alan White

EAA Chapter 27 in Meriden Connecticut has a good collection of construction photos (including the photo above)

PL-12 Airtruk – Aircraft of the month

Quite the unusual aircraft and almost exclusively only found in Australia & New Zealand as an Ag Plane. It was manufactured by the Transavia Corporation from 1966 – 1993 with 118 examples built.

The common way anyone in the US or Europe would likely know about this aircraft is from 1985’s Mad Max Beyond Thunder Dome piloted by Jedediah (played by Bruce Spence). For the longest time I thought something this Bizarre was just made up with some real good special effects, but no its real.

Very interesting to see what people and companies will cook up when not bound by local technical Dogma.
