Just wondering what would be a good first launch motor for my 3" Loc Precision Sandhawk. If this is too vague of a question, it recommends G's or H's.
Also approximate price of motor and any paperwork I need to fill out. I registered NAR and will register NCR on Monday.
Thanks.
Paul
I think this is listed as an 82" / 60oz Bird.
H or I would be recomended. I could loan You a 29/240 case
for an H180 after Geof gets done using it on Saturday Oktoberfest.
I am at work.....can not tell the altitude....it would be slow and low
but it would give You a good idea of what to expect.
My EZI65 . 4" . 45oz goes real well on an H180
60oz is Too heavy for a G.
This is the 3" dia. kit. It is only 66" in length but you are correct on the 60 oz weight.
It has a 38mm motor mount and I bought an adapter for a smaller one.
Also, I'm not sure what I can officially fly as this is my first time at NCR and I have never flown larger than an "E" motor. Just wanting to do more.
Also, the instructions that came with the Sandhawk are a little confusing. What I'm reading is that the payload section is connected closely with the airframe and then the parachute is attached at the long end of the 1/2" nylon webbing. It just seems that this configuration would make parachute deployment difficult.
Also, as I'm new to the bigger motors. Do they have an ejection charge for parachute deployment?
cheers,
Paul
There are many ways to do this...
The shock cord (1/2" webbing) attaches inside the airframe
or onto the motor mount.
The nose cone attaches to the other end.
The chute attaches 1' to 2' down from the nose cone. Some connect
right to the nose cone.
Note: Never hook the chute directly to the nose cone. Use a
quick connect.... The quick connect will take the energy of
deployment instead of the nose cone.
Tons of info at this forum. Review past posts.
Tons of info on the internet. After gathering info off the internet, I
always bring it up on this forum to make sure
This site will be very helpful. www.info-central.org/infocentral.shtm
A G80 may take it to 500' but I think it is to heavy for the weight requirement of the motor. An H180 would be about 1400'
There are many many motors to choose from. Most motors are capable
of deployment charges.
You would need to attempt to get a level 1. Get your level 1.
or let someone fly Your rocket with a larger motor than a G, that
has a level 1 of higher.
If You are under 18, ther is a Jr. Level 1 (I think)
I'll check that link, thanks. How to get level I? I am 38 yrs old.
This rocket has an airframe tube and then a payload tube that I put a bulkhead in with an eyebolt in it and then the cone... the instructions are in Chinglish so a little hard to follow at times. Just don't want to make an irreversible mistake.

This pretty much covers it.
Contact Joe H. And there are many people who will help.
I walked around and ask people down the line. (Are You NCR Level 1?
Would You Be A Witness?) Only took me a couple people.
1- NCR Member.
(Can Be Purchased At The Launch)
2- NAR or Tripoli Member.
(Not Sure If This Can Be Had At A Launch) See Joe H.
3- Prior Notification (to NCR) of intent of Level 1 attempt.
(I'm Not Sure How Long 'Prior' Is)
4- An NCR member with at least that level as witness.
(There Are Many)
5- Safe rocket for attempt with that levels motor size.
(It Gets Looked At. For Safety)
6- Notice to a vendor for the motor to be available.
(Tim at Giant Leap Rocketry Has Many)
7- A member with that level or higher to purchase motor.
(Can Be The Vendor in some cases)
Paul,
Are you heading up to Oktoberfest this weekend?
If so, you'll have plenty of motor options to choose from and lots of great resoures to review the bird and recovery configuration.
Since you already have your NAR membership you are good to go for a certification attempt. I also want to clarify that you are allowed to buy one H or I motor for your certification flight. Tim from Giant Leap may also have some of the level one deals still available --- these are great prices on the motor and case so I highly recommend you find one if you can.
Just as a side note to add to what has been already said
If you wish to certify L1 as a NAR member, witnesses must be in good standing with NAR and you must have either 2 Current L1 flyers witness and sign off on the flight.
Or
You only need 1 person that is certed either L2 or L3 level with NAR membership in good standing to cert your L1 flight.
You would also have to fly it on Saturday's comercial launch event as Sunday is Research TRA L2 and higher.
Other things would be that the people that would sign off as well as the RSO will have to approve the flight as capable and not unsafe.
Tim with Giant Leap will be your best bet for a good motor to cert on as he will probably also have a case to rent or loan as well.
I will be there helping people with Certs and would be glad to help if you need me to.

Thanks for all of your advice... I'm hoping NAR will come back with a membership number and I'll bring along the paperwork and my rocket.
I'm definitely heading up to Oktoberfest this weekend... excited.
We've got you covered, Paul. See Joe first; he'll send you to the right people. Tim Thomas of GLR can set you up with anything you need. What Conway said is dead on; follow his advice. Glad to have you aboard!
8) Paul, The 38mm has a ton of G,H,and I loads in both Aero and Cesaroni. I even have a way nice Loki that is more than up to the task. Stop by at my table anytime, bring your rocket, and we will see what we can do... Tim 8)
You guys rock... see you in about 2 hours. It's 4:47 pm on Fri. Oct. 5th
