Hi, thanks for your reply,

In the test i tried to check the vertical flight of the model as you mentioned. but unfortunately thats found really bad,
my previous model ( Alliance with os 140RX ) did great work in vertical flight ( really tremendous vertical) .
but for now with the Osmose i can do the "Stall" exercise with full engine, so its really surprise to hear that the engine is basically enough for my requests..


*** Maybe you know what is the weight difference between YS-160 and OS-200 ( w header+tune ) ? -
from my check - os-fs-200-p + hatori 824 ( tune ) + header - 1013 gram.

Thanks.
