-
- Buzz,
-
- Adept Rockety has some very nice electonics. Tommy Billings builds
- good stuff.
-
- Robbies Rockets has some easy to use, pre-built ejection modules built
- around a flashbulb. I talked to Robbie a few weeks ago (when I ordered
- some flashbulb igniters and some ejection charges) and he said that he
- had just shipped some of this products to Adept so you may be able to do
- a one stop shopping with Adept. Robbie makes various size charges for
- just about any size rocket. He does custom work.
-
- Tommy required a signature, Robbie may as well (I met him at LDRS, so
- he knew me). This is only a problem if you like to do business over the
- phone.
-
- I decided to buy Adept's Barometric Altimiter w/triggers so that I
- don't have to figure times. This adds a tremendous safety factor since
- the cute will always deploy at the right time regardless if all of your
- engines fired or not. It will even save a 2nd stage that didn't light!
- Put the smarts in the rocket!
-
- Adepts timers are $15-$30 depending on current needs and number of
- timer modules. Their Barometric Altimeter w/triggers is $65. Robbies
- ejection charges are a buck or two.
-
- It starts to get exciting when you put electronics and live charges in
- HPRs.
