Could it be nose heavy? Or too much down thrust, maybe, or possibly both.

I've had that experience with a 200g triplane I made (there's a video somehwere). I just had way too much down thrust due to a high motor position, though the CG was about right. It scooted around on the floor at high speeds without lifting off, so I decided to chuck it - bad idea. It nose diived into the floor a few feet away. So, I figured out it was the thrust angle and pointed the motor up quite a bit (actually above horizontal). It then flew beautifully - straight into a basket ball net that hadn't been retracted into the ceiling. I've been meaning to fix it for a couple of years now.

very nicely done.

Post an in-flight video.

We would all like to see the pretty planes people show off here in their natural element!

How much do these sell for in stores near you? Last time I checked here I think it was $36, which seems rather steep.

Nice plane you have there Paul.

Thanks guys !

$36 may sound expensive but it's enough foam to build 40 or 50 micros with a lot of foam left over I've got Less than $5.00 in the PT-19 and thats including $2.00 for pilots .

Oh I've never had good results with clam shell people.

Yours looked like carved foam

I think yours will flatten out when the flaps are retracted, right?

However if it is a power problem, I learned from one of these sites how to measure thrust by hanging the plane nose down on a digital fish scale. You read the weight, then zero it, then firewall the throttle, and read again.
Thanks for the suggestions to get my Storch chasing rainbows instead of invisible mice (off the ground). I am intrigued with the scale method of thrust measurement but I don't know how much thrust my model needs or how to calculate required thrust. I have spoilerons but no flaps on my Storch. Spoilerons were not deployed when I was tying to take off. hope to try again this Friday evening with a more aggressive wing incidence.
Keep em flying!

Andy2no,
Thanks for your suggestions. CG seems close to where my plan puts it and eyeballing the thrust line puts it pretty close to the datum line or slightly downwards. However, both suggestions are now on my suspect list.
I'll post after my next try.
Bill
