I took my TH Kaos out for its first flight the other day and I had a problem keeping it under control. It was very twitch and when I applied the power it just keep going up. I had to add a lot of down trim and it still wanted to clime. I had a Bridi Kaos years ago and I did not have this problem with that one.

I have an Evo 46 on it with an APC prop and the trims and cg are set per the instructions. I had to add ¾ oz of lead to the tail to get the cg correct.

Are you guys using the trims and cg per the instructions?
