This is from Daves site.....hope this helps. The 180 is to heavy and to much motor.....I have a Saito 180 in mine and it is overpowered.

"The MOKI 1.35 is as much power as you dare put in the DPM 60 inch Ultimate. It has enough power to fly both the DPM EDGE 540T and the DPM EXTRA 330L VERY well."
