October 24 2015 launch report

On Saturday, October 24, MASA held a launch at the Elk River / Otsego VFW Fields. 

NAR Regional Contest Information
From George Gassaway
 
During the October 24th launch, I'll be running an NAR Regional contest.  Same events as last time.  It is for NAR members to compete in officially, but if someone who is not an NAR member wants to try it out, that's OK. It will have the following events:


Open Spot Landing

1/2A Streamer Duration 

1/2A Helicopter Duration 

C Boost Glide Multi-Round

B Rocket Glide Multi-Round

Prizes - For those who do not regularly fly contests, will have kit prizes for the top flights in Open Spot, 1/2A Streamer, and 1/2 Helicopter. 

Feel free to contact me for more info, questions, and any advice on specific designs, kits, or whatever you may consider/plan to use. 

A few tips:

Open Spot Landing - Use pretty much any rocket that stays together (no dropped parts). 

1/2A Streamer Duration - has to stay together, no dropped parts. 

Article and tips on the NAR website:

1/2A Helicopter - Has to stay together, no dropped parts. 

The easiest way is to use a spinning flying saucer like the Applewhite Scimitar ( linked later). I gave out a few of those at the last meeting. But if you want something with more performance, see this article and link to plans here:

http://www.nar.org/contest-flying/competition-guide/duration-events/helicopter-duration/

Also, there is the Apogee Heli-Roc, similar to the Rotaroc.

R Rocket Glide - These have to boost and glide back in one piece, no dropped parts. 

There is a very easy to build and unusual glider called a "Backslider" that some use, designed by Peter and Bob Alway. it is a long 3-finned rocket that has a side vent hole in the nose. At ejection ,the gases push the nose to the side and make the model flip, then it usually glides down tail-first. Here is a link with some more info and plan:

If anyone is interested, I can bring pre-cut parts (semi-kit) to the field and you can build it there using CA and a fin jig, we've done that for group builds before. It goes together pretty easy and quickly (no sanding, just glue and go). Here is a photo of one:

For more conventional rocket gliders, here's the NAR website article on Rocket Gliders:

http://www.nar.org/contest-flying/competition-guide/duration-events/rocketglider-duration/

C Boost Glide - This CAN have parts come off (but if it ejects the motor, the engine casing needs to have a streamer on it). So, the glider can use a pop-pod for example. Or, you can use a piggyback glider, a small glider that rides along the side of a rocket you may already have, and comes off at ejection to glide. Contact me privately in e-mail for more detailed suggestions or something you might want some advice on.

Do realize that a C powered glider can drift a long way. BTW - The "Backslider" could also be used for C Boost Glide, so if anyone builds a Backslider they could fly it on B power first, then when done with the B R?G event go for C power if they want to. 

If anyone has an Edmonds Deltie B, it might shred on an Estes C6, as it is designed for A8 and B4 power. One way around that would be to use a bigger "pop-pod", like say a Big Bertha with a copy of the glider hook pylon attached to it, so it would not boost faster than the Deltie B usually does on a B4. Another approach could be to try the Chinese-made (White label) Quest C6-3, as that Quest C6 has lower thrust, and is more like a C4. But no guarantee it would not shred on even the Quest C6. I will try to remember to bring some Quest C6-3's, so if anyone has a Deltie B they want to try for C B/G. please let me know.
