mosquito4?

[Rex R]

from what I've seen of rocket flyers...this might be a silly question but, has anyone built a 4" diameter mosquito and flown it on an L1500? my q & d simulation has it going 11k at nearly Mach 2!

A 98mm L1500? I don't see how. The body tube on my 4" Jersey Bomber is 18" long, and the 98/5120 is 17"+ long.

There's some bigger ones at Performance hobbies. However, I think fin flutter would destroy the rocket long before it hit Mach 2.

It would absolutely get fin flutter at mach 2.

What was the Pole Cat kit? 5.5" Skeeter. Tim Dixon flew one at MWP last year and shredded the fins on a 54mm K540M. And that wasn't exactly a super high thrust motor. But those fins came off spectacularly. I have the fincan in my garage, waiting for inspiration on how to re fin it...

Jim Cornwell built a 7.5" Mosquito with a 6" motor mount. I made the motor about an N1100 with a 14 second burn.
It went really high and was recovered.

Yep, +1 and IIRC those fins had a layer of 6oz glass.
