ok,
so i have now flown the racer 3 times. each with a little diff result.
maiden flight-
using a 10x4.5sf prop. feels fine, all controls good, throttle up and launch. takes off perfect, flies perfect. no trim required at all. not nearly as fast as i was hoping for but, but it looks good. notice almost immediatly that it has really twitchy tendency to tip, very "stall" like tendency. about 3 mins into the flight i lose left aileron input. it will not roll left. i start to freak thinking i'm about to loose my new plane but get it back under control and pointed back at me using the rudder. i do my best boy scout effort and bring it back to the field and land. upon inspection the motor was very hot, but all control surfaces worked as they should. after this, i just parked it in the jeep and did not fly it agin that day.
so, i took it home. got some grief for running a 10x4.5 sf prop, and decided to try something else. i put on a 9x4E and a spinner.
second flight-
this time i was hand launching myself so i throttle up pretty good, the threw it into the air. it immediatly dipped, dove for the ground, touched a wing tip, then took off. speed seemed about the same, still had sketchy tip stalls, but other control seemed fine. then about the 3 min mark the left aileron went out again. i was standing on the line, with full left input, and it was doing right circles just in front of us. i leveled out, went to rudder only and brought it back in as before. once agin, on the ground all controls were good, and the motor was not hot.
scratched my head and put it back in the jeep. figured i'd would look at it when i got home.
third flight-
i had no intention of flying this plane again today, but after some egging from the "colonel" i said what the the heck, it's gonna fly or it's gonna crash. either way we will see. so, same story, throttle up, launch, have very dramatic near ground collision, and then into the sky. same tip issues but this time at the 3 min mark everything seemed fine. flew for the next min and came in for a uneventful landing.
i think i need to check my RX placement and a few other items. i hope this airplane can become the plane i want it to be. no matter what though, a C-pack motor is not appropriate for the plane to call it a "racer."
laters,
me
