Shaun... congrats on the set-up man!... the video looks great!
I just switched mine to AmSoil 100:1, since I've got a solid 3 gallons of break-in through it... I had to lean out the low and high about 1/16th of a turn and wow.... I'm now spinning a Mej 28x10 at 6760 rpm consistent!!
My 35% Aerotech Yak is coming in at 28lbs and this DA85/KS1090 combo will hover it at 1/2 throttle and pull-out is phenomenal !!
Mine sounds just like yours... an amazing symphony in the air (don't ask the sound police!!). I'm going to try a 28x12 or a 29x10 to see if I can get the noise down.... in the mean time, I've tried a few other props...
Vess 28B: Static RPMs drop to mid 6400rpms, but it's got an insane bark to it during flight (I love the sound, but it's asking for trouble!). Also, I find better punch out of a hover than the Mej 28x10.
Menz 28x10: Static RPMs stay up in the 6500rpms, and it's louder than the Mej, with little difference to the thrust.
Mej 25x12 3-blade: Static RPMs drop to 6200rpm, but in the air, it must unload a lot, because it's no quieter than the Mej 28x10. Thrust is way less
All, in all, I'm sticking with the Mejzlik 28x10 until I can find something that takes the bark out of the DA85 at top end!
Cheers
Trevor
