RE: Thundercat 31 set ups
I just checked out TLR's website and they have some really nice deals on their props. I just bought a bunch of raw octura props from finedesignrc.com, a different vendor and should have checked out TLR's site. TLR would have saved me 3-4 hours of work. It looks like they updated their site and the price for the props are definately worth checking out. I think aquacraft has some good props too, but their although balanced out of the package, need some fine touches (aka sharpening).

Yes, there are forum members who have had bad experiences, but Of course each situation is going to be different. I think I'm going to try the y547 speed bead since I didn't buy that in my last order (I went with raw x646 and m447. TLR doesn't offer raw props on their site, but I'm sure they'll sell you some if you ask). I had an m447 before the thundercat and for curiousity had someone with a shockwave 31 try it. Well his boat woke up BIG TIME. Since I didn't have a boat that was appropriate for it at the time, I sold it to the owner for the price of a raw prop (I did balance and sharpen it but I'm no pro so I didn't charge for what I did).
Just check it out. If you're looking for a prop to pop on, the price they charge is hard to beat. It'll definately save you time. I like to balance and sharpen props, but the copper beryllium, the dust isn't the safest (cause cancer). And when I'm done with one prop, 2 hours passes by.
Currently, I'm obsessed with props since they make such a huge difference when you go from bad props to a good prop. (ie, I have a super vee nitro 27 and going from a stock prop (x437/3) to a abc 4052/3blade increased my speed from 35mph to 39.8mph with just the change in the prop.
Bottom line, after your break in the engine, an octura m445,m447,m645,y547 or prather's 225 will improve speed compared to the stock 215.
Good luck.
