Yes, they are almost identical in diameter. The Proteus X524 is 56 (55,8) x 112.
@Keith. Yep, the seals (o-rings) doesn't fit very tight. Just speaking for myself - It doesn't matter and I'll fix it myself.
@Punisher & Doby. You're both experienced enought to know that when the kv goes down, volts go up (aiming for 25-30k rpm) the amps come down. If I draw 100A on 12s I still get some 4400 watts and get some headroom to 130A (180A burst). The reason why I'm so sure of this is because a friend runs a 40" cat with a 560kv 4962 Outrunner on 12S with a 80A HV esc with a 57 mm prop. His esc is 86 degrees Farenheit after the LVC hits, which means he can't be drawing more than 40-50 amps......and his cat is plowing through the waves. CG is way off. Maybe a 67 mm prop is a bit over the top but let us join up in this thread next may - june and see how it went
