Ok, we'e all waitin, class is now in session. Lol! Just kidding, man. Honestly would like to see it when you are done. Maybe you can give me a couple ideas.
I have the KST515 on the tail of my 450L right now, it's a hi voltage servo, and does good on the lower voltage, but I went ahead with using it, because I plan on upgrading to hi voltage all around in the future.
