g'day john, we (test pilot with the steely nerves and me) have just completed test flight #8 on s/m f18 and i thought i'd share some results with you. i found the same sort of slop in the brass bushed elevators, to me totally unacceptable on a high performance jet, fixed with jetlegend twin ball bearing blocks and a bit of surgery(see photo), also extended torque arm to 45mm, this gives 40mm trailing edge movement with 140% servo travel, 10% for trim, and new servo mount to realign pushrod, sounds like a lot of work but our results leave me feeling totally vindicated. started with c/g on front spa but have since moved back approx 2 cm( don't quote me on that! approx!) with much better handling at flair, cg checked with rear tanks full, front tank empty(i drain front to rears to header) its heavy, but flys absolutly on rails, the s/m and j/l hornets are good flying models, with a bit of attention to detail they are superb flying models. pst 1300 gives plenty of power and excellent performance. a friend took some video and will post here soon, look for tiger hornet vid or send pm for more details
