well i found the lead and have since test flown the model. it flys very nice but second flgith was cut short due to cowl and cannopy failure. heard vibrations on second flight and strange noises so got it on the ground nice and easily to find canopy cracked and cowl disitigrating. cracks all over it. i new it was very soft plastick for a cowl but it certainly takes the biscuit. emailed world models about this now awaiting for a reply. il take some photos of the damged windscreen in a short while and get them posted. those photos where taken after 2 sucessfull maiden flights of my cub and friends thunder tiger. We both had issues with our engines that day too. as you can tell by the pil streak mine is caput. Just rebuilt it with asecond handcrankcase off fleabay. cost me 5gbp to fix the engine.
