F3A Biplanes have a future!

Matt,
 
Do you have any pictures of the "Express" it would certainly make some
interesting viewing?

Hi all,


I had to opportunity to watch a F3A biplane fly for a short while in the
hands of a very capable pilot last weekend. The model was built by a local
kit manufacturer who adapted a set of wings to Carrera 2000 (Designed by
Peter Goldsmith)as an experiment. 

The model was flown briefly through the P03 schedule until an unfortunate
problem resulted in the model having to land minus wings on one side of the
fuse (More on that later) Anyway the flight looked very impressive
especially in the broader speed envelope the model was capable of flying in.
The model was powered with a YS140DZ and weighed about 10.5pounds.

The very experienced F3A pilot commented how impressed he was with the model
and felt it was already better than his current monoplane. Particular
comments he made was that it spins, stall turns and rolls great snaps would
have been great until half the wing was ripped off as a result of
overstressing.

What this pilot did as the wings tore off was truly impressive. With the
wings completely ripped off from one side of the fuse he had the initiative
to throttle up and fly the model in knife-edge and fly it around to make a
crash landing approach. The end result was a few scratches to the fuse and a
broken prop. This was one of the most impressive things I have seen.

It is a pity I didn't have my video camera with me as it certainly would
have been great to see over and over again.

I was very sceptical about F3A biplanes in Pattern until I saw this model
fly on the weekend. I have no doubt that will be taken seriously at the next
world champs. 

Follow this link to view the model prior to it crashing.

Peter,

Bipes make a great deal of sense in the present F3A environment with its
snaps, rolling loops  and assymetric maneuvers in general. And as far as
speed control is concerned the bipe should have the advantage. Whether they
overtake the monoplanes in F3A overall, well the jury hasn't even gone to
the deliberation room yet.

Personally I like bipes, but I like Nat Penton's purpose built mono, The
Express, even better. Form trully follows function in this design, which Nat
has perfected in over 15 years of refinement. I would love to see one of the
top pilots fly this model for 50 flights and really wring it out.

regards

Matt Kebabjian
