Want your rocket to fly higher and faster than the designer intended? Want to save money at the same time? Want to get more involved in the prepping of your rocket so you can be even happier when your hard work pays off and you have a perfect flight?? Sure you do! Rocketry is all about adventure and learning- Doing something that might be a little difficult and doing it well. Get an F reload into this case, cram it up the tailpipe of that lightweight Estes D kit, and watch it really perform! Just make sure you at least have an idea of the correct delay- Obviously it should be longer than you would use with a D motor. If your rocket flies well on a D12-5, for instance, DON'T put an F24-4 in it. Work your way up from what you know... Ds, then Es, then Fs, and keep notes. And read and follow instructions exactly until you know what you're doing.

Small, but essentially a carbon copy of the larger versions of the RMS system. I now have two, and have had no failures in many many cycles. Only downside is need for cleaning. Use a good grease, clean them as soon as possible after using, and they should last a very long time. Many suggestions out there on cleaning, I prefer to soak a bit in white vinegar, then wipe down with paper towels and Q-tips. Baby wipes will do the job if you need to do a quick turn on the field.
