You can clearly see that the old rudder was under size ( the runt of the batch of 8 that I originally cut out) when you compare it with Jake's yacht, i would not only expian why i can't complete a gybe/tack with a constant breeze but also why my boat suddenly changes direction in turbulent winds. I designed the new swept back one myself , it has a mahogany center core and balsa hydrodynamic (wing shaped) shaped sides! You never know it might even work! It's hardly what you would call balanced! But being a Footy shouldn't put much strain on the servo ,in all this I've learned Footys by nature need all the stability they can get! Btw my boat only looks clean because the photo is over exposed, it's actually filthy! White isn't a practical colour when you sailing in mucky ponds!
PS Have just sliced off that tip at the bottom bcz it would add nothing but drag. I'll have to make that weight a bit more sleek at some time ....and intend to experiment with AAA batteries.
