RE: flite streak
I haven't personally built the flight streak, however my dad has, and still has it after powering it with a Fox 35 Stunt. All I can say is use long lines and hold on, its fast! I would imagine the Fox 36 will be fine. As far as the bellcrank, I have never examined it to give specifics, but I would imagine it will not be a problem. I hope this answers your question.
Also, as far as no one responding to your first post, I would imagine very few people on here are interested in control line now verses how popular it was in the past (I might be completely wrong but I am fairly young, just an observation), especially ones that might have built the Flight Streak. However it is unusal to see a post go unanswered.
Good luck with your plane!
