My dear Guy,
As I told you in the past, I cannot see why we need limitations to
F6A models. I advocate leaving the options to the pilot, with the
20kg limit for F3M. We have a regular F3M contest schedule in
Belgium, with about 15 pilots flying four nationals and a
well-attended international meeting. Most of these pilots declined
participating to the F6A selection contests we ran last year because
their models did not comply. Only one pilot did purpose build a
model and eventually was selected for the WAG. There is no question
about the attractivity of these large models flown on music in front
of the public.
And remember that the present rule allows 15 kg jet models to
compete. For these, the span is a MINIMUM of 1.8m and no maximum...
Why should propeller models be limited when large and heavy jets are allowed.
Maybe we should first decide whether accepting propeller aircraft,
jet-powered aircraft and helicopters in the same category was a wise
decision...
Thanks for promoting this discussion.
Hi Robert,
The matter has been discussed numerous times before. Larger planes
are definitely out, primarily for cost reasons, considering the model
itself as well as the freight costs. Up to now the limiting factor
has been the weight, preventing use of the low cost (and low
operating costs) of gasoline engines. With the weight rule lifted,
then there are numerous, moderate cost 2-m planes on the market, able
to be used with30 to 50 cc gasoline engines. The Extra Fun by 3W, as
mentioned by Donatas, is an excellent example of this. Freat fun with
a small 3W engine, a real competition beast with a DA or MVVS engine
of slightly larger capacity but still a moderate price tag. More
importantly, the operating costs are much lower than what is required
with a 25 to 30 cc methanol engine or an electric motor.
