Forgot one thing, I'm using the ''EVSD-5U-PRO Airpower multivalve thing'', and I notice that one of the main gear does not retract completely in flight, and when the gear retracts, it's looks very ''scale'', as if they don't get enough air.
I have no restrictors etc in the lines for the gears, have any of you experienced the same (low air output from the EVSD-5U-PRO) ?
I'm running with 8 bar pressure, and it works ok on the ground, but doesn't ''slam'' the gears in.
i had the same with a tucano , i think it is better to use 4mm instead of 3mm airlines.
a trick i did was using 2 more airbottles , this made the total volume better and kept the pressure high for a longer time.
as for the main doors we all agree it needs larger cylinders
Thanks for the suggestion Sandor,
I will try and change the airline to 4 mm instead of the 3 mm for the main retracts and see if that makes a difference, I already have two bottles, one big and one "standard" one, if I add more, it will take me 30 minutes to fill the plane with air

Sverrir: Oh yes, that would probably mean that I would have to re-arrange the batteries in the front just a little

Regarding weight, I have located 3 x 2S/5500 mA/H LiPo (total weight 930 gr) in the two front "trays" for the batteries, that put the CG right on 240 mm, no extra weight needed with the P200SX in it
