i just finished my first Razor. I made a couple of mistakes though, but i think it should sail. It got a bit heavy - exactly 550 grams complete. Probably the rig is too high, but it is interchangable, so i can design others to adapt to different wind forces. And i think the rudder could be too small.
I got into Footys last september when i was planing a trip to Sardinia and as we were 5 people in the car, i was looking for a very small rc sailing boat and the footy was ideal. But i had no experience in building any rc models exept for a micro magic kit i built last winter.
At first it was a big problem to print out the plans in the correct size because of different paper standard sizes, which drove me almost crazy, but finally i got them printed in a copy shop. After i solved that problem i tried to build the Cobra hull but failed completely. So i built the Papaya hull, but didn’t finish the complete boat in time for the trip, so it moved to the shelf to catch dust … until it came back to my mind a couple of weeks ago. And as i looked over some plans i realized why i wasn’t capable of building the Cobra hull: i must have made a mistake in converting inch in millimeters and took 2mm balsa :rolleyes:
Now i tried 0.6mm for the Razor and 0.8mm for the Cobra hull, and both were built pretty fast. I decided to complete the Razor first and had to realize, that making the hull was the least complicated Casting the bulb and making the rig and sails was not that easy and took a good bit of time.
But finally i made it (It was a bit of a challenge because i’m a student and my studying/living/sleeping/working room is the same and i don’t have that many tools).
Now i just need a small pond to test it. I havent seen any suitable ones yet. The ones i know are too big, or the edges are not accessible, and i don’t want to loose the boat if something goes wrong while testing. It worked well in the bathtub though.
This Forum is great, and all of my questions were answered just by reading trough the threads. And while building and reading, i got lots of new ideas i will put into practice while completing the Cobra (which will take some time because i got a couple of exams the next weeks).
Well, here are a few pics:
…yes, i should design a proper boat stand…
