Hi Peter and Rudiix,

how are your Hirobo helis? the 'latest' video i have for my hirobo Bell 47G is here.

this was with the symmetrical blades, which hover ok in UK but when I brought heli to Asia with warmer and more humid weather, it did not lift at all. I have then changed to semi-symmetrical vario blades and it make a BIG difference! with same engine settings, it lifted half throttle!

so, if you are having lifting problem, try semi-blades if you have not done so, just some sharing.

Cheers

Lawrence
