I think you'll find it's about the same. Unless GROSSLY out of whack, the low end pretty much affects just the bottom third. What you will find that may be an adjustment for you is the lack of linearity... when these carbs get about 30% open, you're at about 75% rpm, with very little change over the rest of the rotation up to full bore. Longer arms on the carb and servo help... as does having a radio that can have a good expo curve on throttle.

I actually don't use a curve anymore, as I just use a 3/4" arm on the servo and 7/8" on the carb, with the pushrod length adjusted with throttle stick at half, and carb arm just under 1/2 open. I've done both of my current setups that way, and the linearity is pretty good, actually.

Not good enough for the fussy 3D guys, but I don't do no steenkin' 3D....
