Leo,
Thank you for putting this data together. That would mean that the weight
increase prescribed the rules is conservatively 4 times the increase in
covering material weight.
Viva 1.25g 55cm! (I'm only half kidding)
On a productive note, I fully intend to submit a proposal to change the
current new rules in 2 years time. My question is would we like to rules to
back to 55cm as we have known it or, should we take the opportunity to
bring the model specifications into accordance with current airline travel
size restrictions? I am thinking of a something like a 1g 50cm model with a
0.5g motor.
Regards,
Nick
