Not to bash anyone but Im going to answer your question-not reccomend another heli:-) I now have 3 different ventures floating aROUND AND LOVE THEM! dazz has a good point.The fuel/clunk line is somewhat miserable so its not a bad idea to go ahead and change it right out of the box.As i type I see the ideaology behind putting that bolt into the tail rotor ball link.Good idea and good observation!The os 32sxh after break in will do the job day after day in referance to just flying around.As far as 3d goes, the webra black head seems to suit the application just fine.Servos, I ran jr 537's all around and it did fine.I did try a 401/9253 combo and intend on sticking with it as it locks the tail in very well...prices ..I believe heliproz has the venture/os/32/mavrikk muffler combo for somewheres around 369 shipped.I dont know where 450 came from??Try heliproz and/or give them a call and theyll hook you up as far as prices and reliable information.Hope that helps.D
