rear ejection links

Anyone have a link to a good "how to" website for rear ejection methods (pictures preferred)? Upscaling a mosquito and figured it would land better in the nose down position.

I'm doing an upscale Streak, which is basically a Mosquito in disguise.

How upscale are you going ? Mine is 5.5x with a CTI 2 grain Pro38 for my level one certification flight. I'm using dual deployment, with motor ejection at apogee separating the body right where the leading edge of the fins are.

Then at 400 ft my RRC2 will blow off the nosecone and deploy a chute for a nice, soft landing.

Enjoy your skeeter...

If it's a major upscale, dump rear ejection and blow the nose.

I've been flying a BT-80 (3.6x) Streak for over a decade. It's often mistaken for a Mosquito, but us old timers recognize the difference in fin sweep. Besides, you have it backwards: the Mosquito is a Streak in disguise. The Streak predates the Mosquito by about a decade.

The Streak was my very first rocket launched, back in 1964. It made 3 flights on 1/4A.8-4 motors before being lost. I built the 3.6x Streak for my

30th anniversary celebration in 1994. In 1999 at NSL in Huntsville, it was autographed by Homer Hickam, and retired. A 5.6x Streak has on my TUIT list for about a decade now.

You're right. I was remembering in reverse and reached the Mosquito first as my mental tape re-wound.

Same here. Couldn't afford much in the way of GSE so the launch rod was just stuck in the ground. Eight 'D' size batteries soldered together in series (still remember the burn I got assembling them) and a push-button switch dontated by my Dad heated up the nichrome coil I had carefully wrapped around a pencil point. Lost mine on the second flight :-(

Remember using a plug of toilet paper to hold the ignition coil in place ?

Times change. The reload H143SS for my Level 1 cert flight is going to cost more than I spent on my first three years (about 12 rockets) in the hobby !

ah another hijacked news thread ;-)

What was the name of the Centuri model that looked like a Mosquito? Was that the Streak? My little brother had that when we were kids back in the late '60s, and I had the next one up. The Micron I think was the name of it. It had streamer recovery.

Lil Herc? Then there was a paper Two Bitz.

A girl at our last launch had a upscale Mosquito flying on a G55 (Was planning to fly an H, but desided not to after an hour of failed launches trying to get igniters to lite the G). It was the first time she had ever flown it and not broken a fin off, so i'd say its a good idea to land nose first.

Make that:

gallery software changed the numbering when I uploaded more images.

If, at a later time, this still isn't the Mosquito, browse the Album for it.
