Well I would like to start by saying thanks to the KEP's 21, FF.12 (now a .18), and the JAP I'm a rigger junkie!!! :blink:
I have a few question about different parts of a rigger design that I was hoping to get some help with.
Lets say I'm building a .12......
1. Is there any starting points for how far forward the sponson's should be located in relation to the tub? How about a good starting AOA?
2. I have seen turn fin's on the sponson's, and on spars, is there any reasons for the two different mountings? and is there a relation between turn fin and anything like cg?
3. What a 'baseline' for sponson depth below the tub? Any rules of thumb on this?
4. How bout depth of rear shoes / skies? besides the depth any pro's / con's of shoes vs. ski?
Thanks for any info I can get! I'm having too much fun and I want to try to build up my own.!!
