its not getting into the air thats the problem... its a 2stroke... everything seems good on the ground so I do a take off it climbs barely and starts bogging and dies... I tune it on the ground to give me at full throttle no power loss and constant RPM... and then I richen even a little bit more... the response on LSN is good... it gets good speed on the ground no bogging just get a good sound of power... but as soon as it starts to climb... I really cant understand this...
