I have a Quest Harpoon and launched for the first time it went straight up for about 150-200ft then went at about a 65 degree angle. Is this normal? I had a C6-5 engine in it

What could have happened is the rocket weathercocked, or the wind blew from one side and it pushed on the fins (and the body tube, but the fins more) and rotated the rocket. The rocket rotates around its center of gravity, which is where it'll balence, it balances further forward if the motor is burnt and thus lighter (less weight at the rear), and if the fulcrum is further forward, there's more. surface to push on on one side of it. Weathercocking happens into the wind, since the back of the rocket follows the wind and thus the front turns into it, like on a weather vane.

Either the rocket flew into a layer of air with higher winds or you were launching while there was wind, but the behavior is normal.

Too complicated; didn't read: Normal.

short answer, yes. Mine did the same thing. Add more nose weight. Quest doesn't add enough. I just squeezed a bunch of carpenter's glue in it and flew it on the C motors.

It has lots of fins so they do tend fly weird if not in perfect alignment or they get hit with some wind. They like to whistle a lot too. Just keep flying, maybe a C6 3 with more nose weight, welcome to the wonderful world of scale model flying!

Did you mean, "Nothing but wide open flat land"?
If you don't mind me asking, where do you live?
I'd like to look it up on google earth.
Feel free to PM me your address, if you don't mind.
It will only be used to look up the area on google earth.

I've been looking at that area to move to. Small towns around that area.
Housing is expensive though, probably not much for the wife to work at either.
But she doesn't want to move to that part of the Country anyways.
She wants to move to Oregon. That place will drive my sinus's crazy.
Thanks for info.
