Rick that 3w 24 will really be a disappointment, I would go with the moki 1.8 or a saito 1.8 for 3d

Any gasser will be to heavy for that wing. My H9 edge is like on the border line with the ZDZ 40. Plenty of pure brute power but i have a larger wing than the lanier edge.

You also might try using a smaller prop like a wood menz 17" prop
I believe that 18x6 Keeps that engine a little bit off its power-band in a hover.

I guess the only other choice would be to get your giant scale in the air.
