Merry xmas and a prosperous new year to all gyronuts.
Whilst not wishing to be a killjoy! My advice for the Wallis is apply full power, release the string and as the model is just about to pitch up and become airborne throttle back to about 70 - 75% throttle and it then FLIES quite nicely but is VERY difficult to orientate. If you don't throttle back then it pitches up to the near vertical ...everyone runs away and the model hits the ground ...the blades swing back and the model motors along with a strange wobble BUT little or no dam,ge except to ones pride and underwear!! I have a video of this strange phenomena!!
Best advice....sell the model on ebay and build a direct control one from plans... see www.autogyro.com or artf/kit from www.autogyro-rc.com.
You won't regret replacing the Wallis. Thats what I did. Bill
