So, this will then be my first post, after reading here for quite a while, ive got about 30 hours on raven 2 and I can only say that 5 seconds of priming was allways enough, but i learned that you shut push in the mixture quite fast while starting, not directly full rich, but also not too smooth. In comparison to the raven 1 it seems that the raven 2 just doesnt startup that nice
but otherwise it flys way nicer
