Interested to hear if anyone has had good sucess in changing a fin with a power box base to tuttle.
I have a F1 falcon i need to change if I can.

Pepe's been changing boxes like crazy, upright tuttles to 45deg powerbox, now back to tuttles again. he doesn't seem to have any problems.

Hi Jman,
I have converted a few Techtonics PB fins to Tuttle. One (Falcon) was shortened by 2cm, the other (Tomcat) was kept the same length. A PB head fits in a Tuttle Head mould with minimal modification it is a very quick and easy conversion (if you have a tutle Head Mould...)
Here is a bit more info:

Thanks kimba thats the sort of info Im looking for, I will make a mould and give it a go.
