Need level 1 certified on the 15 at TIMPA launch site

[dgha...@gmail.com]

I am finishing up my high power goblin. Before the Agua Blanca launch talked to someone about getting my NAR level 1 certification. I don’t remember his name. Can I get someone to help me get certificatied? Can someone recommend a good motor for the launch. I would like to order it today so I can get it delivered before the 15 th.

I won’t be at the launch on the 15th - still in vacationing in Iceland - but am happy to help at the next launch if you don’t do it in June.

I can't attend June's launch, but it's likely me you spoke with at Agua Blanca.  I'm going to trust that a potential NAR mentor from the members list will pipe up with mentoring help. As for a recommended motor, that's going to depend on your model, both in diameter, and thrust profile. Make sure you model your L1 cert flight in Rocksim, OpenRocket, or Thrustcurve. That will give you the best indication of a good motor for your cert flight. Watch altitude (1000 - 2500 ft), pad departure speed (50 - 80 ft/sec), and thrust-to-weight ratio (between 5 and 20) and max speed (< Mach 0.7). I like that range so you can see the whole flight clearly and stand the best chance of successful recovery.  Avoid sparky motors, because field conditions in Tucson's dry season seldom permit us to fly them.

On the day of your certification, keep wind speed and direction in mind so you don't overfly the field; there are no-go areas to the east of the TIMPA field that you'll need to avoid. Do the math on drift distance in various wind conditions for the expected duration of your flight, and project that onto the TIMPA field to get an idea of where you can and can't recover. There is always another day to fly if conditions aren't right. And knowing when not to fly is the most important lesson you can learn from your certification process.

I can help with certification if you still need a mentor.

Reach out to me via email and we can connect from there.
