SAS Wildthing fin attachment modification

For those of you flying the SAS Wildthing. Are you fed up with the model flipping over on landing and the fin being bust off? Well I have the solution. Attach the fin using rare earth magnets as per the photo's below.
I used a drill bit a similar diameter to the magnet and created a crater in the balsa side brace to one side of the fin and glued the magnet in. I then did the same diagonally across to the rear of the fin. Then corresponding craters in the foam wing with a magnet glued into each. The fin is now secure enough to fly but will come off in a heavy knock and, also makes the model easier to transport.
