Would c6-7 fly a rocket fine that recommends a c6-5?
 

A local hobby shop by me has all their c6-7 engine packs on clearance for 2$ and before buying them all up just wanted to make sure there cool for flying rockets where a c6-5 is recommended.

The difference between the C6-5 and the C6-7 is, of course, two extra seconds of delay before the parachute is ejected.

If your rocket is usually still going up when it ejects its parachute on a C6-5, you *may* be ok with flying it on a C6-7. If your rocket has slowed down and is just about to tip over or pointed down when it ejects on a C6-5, you *DO NOT* want to fly it on a C6-7.

The C6-7 is for small rockets that will coast a long time. Larger rockets, or heavier rockets, do not take as long to slow down, so they need a shorter delay time.

What rocket do you want to fly them in?

Build yourself an Estes Astron Ranger or Astron Cobra clone and fly it on three C6-7's. At $2 a pack, it's a lot more affordable to cluster than it is at the regular $7 a pack. :cool:

The book recommends C6-5's for them, but you can get away with C6-7's on days when it isn't windy.

Photon Disruptor II

Interceptor

Red Star

Saturn 1b 4 motor Cluster

The delay is way too long for the Interceptor and Saturn 1B.

It is marginal at best in the Photon Disruptor II. It is BT-55 based compared to the first one that was BT-50 based. Even the smaller original recommended the C6-5.

The Red Star escapes my mind right now.

Buy them all, and get into staging. Seriously, I would not pass this deal up.

So now you have two great reasons to buy up the C6-7's. Clustering and staging. :cool:

BTW, don't forget to get some B6-0 or C6-0 booster motors if you want to try staging.

Ive never really looked into staging but its something im sure ill get into eventually. thanks for all the great info.

Then by all means, build a cluster rocket. :cool:
