Tank position with the LS motors tends to be a factor in getting a good needle setting.
I run the Nelson LS in my Sweet-V and I like to run the Jett flat tank. I install it 'high' in the fuselage. ie. I put it under the front wing hold down blocks.
A little Dremel work on the epoxy under and around the blocks and the flat tank slides in nicely under the two blocks. This is as 'high' as the tank will go.

This position allows me to set the needle very near peak on the ground. The motor goes just slightly rich in the high G corners and peaks on the straight away.

I have had good success running my Sweet-V this way.
