Dear Mr. Alfons Hubmann
I'm very interested for the modification of the Velocity you have
accomplished.
Is the minimum speed of 58 Kt for the maximum weight?
What do you mean by the speed unit of 'KTIAS'?
How have you decreased the minimum speed of the Velocity?
Can also I know in detail about the insulated exhaust system silencers
and the cooling-system optimized for long climbs?
I'll really appreciate your kind reply.

The three only flying Velocities with FAA-approval have met about a year
ago at St. Gallen Airport, Switzerland
I have sent a message with picture to the reflector.
We have gone in contact with Velocity to convince them about the fact,
that not one Velocity would ever get an final certificate
If it is built in accordance to the manual.
JAR / FAR 23 regulation will be enforced much stricter than up to now in
due course. (Immediate grounding if out of tolerance.)
We have made changes to the following:
Canard, rudder, wing, Engine/Prop placement, Cowling, insulated exhaust
system with resonanz- + interference silencers, cooling-system
optimized for long climbs.
The most important results are: (and you are invited to test them
with your Velocity)
-Vs < 58 KTIAS
- Gliding# >18
- Noiselevel < 75dB(A)
D15 < 450m
ROC 1100 ft/min
In addition we have re-engineered the front-strut in order to eliminate
shimmy.
We have proposed Velocity to integrate these improvements into the
standard. As there is seemingly no necessity for the US-Market, we have
come
to the agreement, that we are under the name : Velocity Europe the
representing partners and we sell Velocities and the Europe-Kit to the
future builders over here.
Last weekend we were three Velocities (Wilhelm Maul, Denis Wood and
myself) in Kemble, UK and next weekend we are presenting Velocity at
the fly-in
at Chambley Bussiere, France.
Whoever is crossing the atlantic is invited to join.
Now you know most of our actions and intentions.
Best,
Alfons
