This site hosts information about the experimental aircraft BD-4. The
BD-4 is the first real kitplane in the world. Jim Bede designed and
started to sell the kits in 1968, that's almost 35 ago! Despite its
age, the BD-4 still is high in demand; no real surprise when you look
at the specifications below. It is still one of the fasted 4 seat experimentals,
but requires a fraction of building time and financial investment in
comparison to younger composite designs.
The BD-4 has an excellent safety record. From all experimental designs
with a larger number of high time aircrafts
it is the only one with no reported catastrophic structural in flight
failure, as far as I know. A rough analysis of the accident numbers
in the NTSB database since 1983 reveal an accident rate that is about
half of the combined other designs.
The situation around BD-4 kit suppliers is currently undergoing some
changes. The main players are (in alphabetical order) Jim Bede's BedeCorp
and TVAP which reformed
as new company Team Aviation at the same location. I will continue to
report about the latest developments in the yellow "News"
block to the right.

Despite the fact that the BD-4 was designed 35 ago it is still a very
good alternative as an experimental plane. These are the main advantages:
- Relatively easy to build (everything
is pretty square)
- Proven design with numerous modifications
and design improvements that were developed in 30 years of building
- Fast: up to 190 MPH cruise with a
200 HP engine
- Fuel efficient: up to 20 MPG (in
1983 it was Roger Mellema's BD-4 winning the CAFE 400 race against
a number of modern composite designs)
- Can seat 2 adults and 2 kids or 3 adults. If built with a fuselage
extension it's a true 4-seater.
- Long range, fuel tanks up to 80 gal
(or even more)
- Inexpensive to build, if built from
- Multiple engine configurations were tested and used
- One of the best designs to incorporate custom design modifications
The BD-4 does not have the best reputation as a pretty bird. The fuselage
is somewhat boxy. Judge yourself by browsing in the gallery
or looking at the planes from the builder's
