NAR Regional Contest Information
From George Gassaway
During the September launch,
I'll be running an NAR Regional contest. 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
1/2A Streamer Duration - has
to stay together, no dropped parts.
Article and tips on the NAR
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:
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
For more conventional rocket
gliders, here's the NAR website article on Rocket Gliders:
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.

The day started with dew on the grass, light winds and cool
temps. As the day progressed the grass dried out, the winds
increased to a high of 10 mph, and the temps got into the
upper 70's. What a great day for rockets.
There were a total of 96 flights on the sport range and
many great flights on the contest range.
The winner of the Micro Maxx Duration Contest and the
prize of a Micro Classics Space Cruiser Ezxcaliber is
Stuart Lenz with a time of 15.34 seconds. Since this was
one of his kits he donated the prize to Michael
There were 4 contestants (Michael, Stuart, Neal &
Todd) in the contest and a total of 8 flights. There
were a few more flights but they were not even close to
being good enough to be entered.
I had a total of 10 flights on the day.
2 in the Micro Maxx contest. My Micro Green Goblin had
the closest time to Stuart @ 11.46 secs.
I flew my Aura on an F15-8 with an Altimeter 3 on board.
I forgot to hit the start button on my phone so I did
not get any data. Despite the chute not deploying in
landed with no damage.
I also christened my Mega Red Max on a G77R for a very
nice flight to 836'.
I flew my Madcow Lil Green Goblin on an F62T but for
some reason it was severly unstable. This rocket had
flown several times before without issues so I am not
sure what happened. It ended up breaking off one of the
fiberglass fins when it hit the ground. Another rocket
in the repair box.
I flew my Mega Red Baron glider 4 times. 1st on a D12-0,
twice on E9-4's and last on a E12-4. All of the flights
Thanks everyone who helped with the range setup & tear

The totals were: 97 flights with 103 motors burned.
