Avia BH-5 Replica Aircraft
Construction of flying replica of Avia B.H.5, Czechoslovak legendary aircraft from
the time period between World Wars, is finalizing. This type won an array of domestic and
international races in its days and it became holder of the King’s of Belgium Prize
and the prize of the Belgian Tourist Aircraft Contest in 1923.
Mr. Marcel Sezemský, who has built another historical aircraft
in the ultra-light category
also in co-operation with our company, is an original initiator and a main builder of this replica.
Enthusiasts of Historic Flight club,
with Mr. Milan Mikulecký as a chairman, are completing accurate replica
of this plane in a hall of Walter company at Prague — Jinonice under
the technical supervising of CAA CR staff.
The aircraft will be driven by the original radial five-piston engine Walter NZ 60,
which overhaul will be done by
Flight Aerobatic Centre
from Moravska Trebova.
Drawings for this replica has been created on the basis of preserved part of original ones
and well-preserved photos.
We have guaranteed aerodynamic and stress analyses of the whole plane in accordance with
current regulations, because it was necessary for obtaining of the Certificate of Airworthiness.
This replica was presented to the public in its, at that time, still unfinished state
as early as 25 January 2005.

VL-3 Aircraft Strength Tests
On Wednesday 16 March, 2005 we have successfully finished another group of strength tests
of the VL-3 aircraft in the manufacturing workshop of the
Karel Klenor — KLN
company at Chocen.
Units of empennage, rudder and fuselage, inclusive of engine mounting has been loaded
up to ultimate load.
As at the wing strength test (see below) we have proofed strength of these parts
for maximum take-off weigth MTOW=560 kg (1,235 lb).
Not a single tested parts has failed at these load levels.

Basic Prototype Tests VL-3 Finished
VL-3 aircraft take-off at tests
Today we have completed basic prototype tests successfully. These flight tests has been
carried out by Jiri Unzeitig, our test pilot.
A presumption of high cruising speed has been confirmed, when we have reached
economy cruising speed of 210 kph (130 mph) CAS
with Rotax 912 S engine and SR3000 adjustable propeller at 50 % of maximum engine power
(37 kW/50 hp at 4300 rpm).
The aircraft is able to fly at airspeed of
280 kph (174 mph) CAS
in level flight and with climbing rate greater than 5 m/s (16 ft/s) at
MTOW=450 kg (992 lb).
