It is funny when we start to talk about competition the word " equalize " starts appearing.
if it's a fun fly then have fun but if the RULES ALLOW then they will be pushed to the limits.
If the event is a 1.5m span with speed 400 2 min run..then you'll have guys with skeeters and multiplex speed 400's and you will have the guys with composite 1.5' and a high $$ motor combo or guys coming up wild ideas with in the rules. It's with in the rules but now the big spenders are needed to be equalized...but this is how we advance the sport, technology and people pushing limits. This is how cool stuff comes to market and we all can enjoy.
Only way is to have a one design with specific plane, motor, prop U get the idea..
