I remember those G80FWL. I think you could buy ten from Ross at Magnum for $100 or something like that. Excellent motors!

Canít wait to try a few out Gary. Thanks for the update.

Gary,
Any chance you will be making the G80-4 again?
I love that motor!

Canít wait to see what the thrust curves look like.

Oh, yeah... Iíll have to go digging to see if I can find the 2 or 3 I have stashed in this mess .

As you may remember, we dropped that delay in 2007 when the G80 was redesigned to produce 137 N-sec, which was a 42% increase in total impulse over the previous design. Because of the increased total impulse, heavier model rockets using the 4 second delay should now use the longer 7 second delay. I suppose a 4-second delay could be useful for high power rockets weighing 4 or 5 pounds, but we would not want to see them used in kits like the G-Force or Sumo.

I have several fairly heavy NCR rockets, but love my Bomarc. If I used a 7 second delay, it would hit the ground before the charge went off. I like SU motors; not a fan of RMS. The G80-4 was perfect.

There is a DMS G80T-14A that you can drill the delay but the DMS drilling tool is set up to take 8 sec off at the most, you could use a regular bit with a drill stop or a tape stop if you wanted to get to 4 or 5 seconds.

I think it is great that manufacturers are developing/producing more motors in the traditional 18mm x 70mm size.

I can't wait to try out these new Quest motors.

What I would like to see are some longer burn motors and a method of reliably staging small APCP propellant motors.

Longer burn 18mm composites are going to difficult because of the smaller throat size needed. You just canít get an initiator in anything much smaller than a 0.090Ē diameter nozzle throat.

We have found that you can stage a C-size black powder booster motor to a C or D Q-Jet.
