Q-11

Ivan,
Since the conventional tail version did not include an updated instruction sheet I was wondering if the CG point is the same for the V-Tail and Conventional Tail?

Cg

Bob,
The CG position was set up in process. The last recommended initial position is ca 70 mm behind the LE, for both versions. Anyway, make diving tests atc. to setup it to your requirements.
The new instructions are now on the web, same for both versions. The building images are now on the web only.

So, is the only way to get one is to go direct? This would make a very nice plane for the US 28mm class.

I think these are meant:

Quote:
Out Runner Class
Motors are restricted to out runner type without gearboxes. The maximum size of the flux ring is
28 mm in diameter and 16 mm in length. There are no restrictions on airframe size or planform.
Batteries are restricted to 7 Nicd / Nimh or 2 lithium polymer cells.

http://www.soarabq.org/pdfs/f5j_rules.pdf

there's these as well:

Quote:
X5J eXtreme SOR rules:

1. Any airframe, battery, ESC, prop, motor with 28mm diameter and 17mm
magnet bell length or less.
2. Flight time has motor run time subtracted from it.
3. 30 point landing tape, in 1 meter increments worth 3 pts/m.

Ed, Just got some final weights on my build.

With a Hacker A20-20L and a 3C 1350 mah pack, AUW is 19.5 oz.

With a smaller Hacker (A20-26) and a 2C Pack you could be under 18 oz.

Rules

Thanks.
The rules of the Eurocup are here:

http://f5j.eu/w/index.php?title=Euro...ner&oldid=2852

Very similar. It is minimum weight limit (maybe redundant) and minimum prop dia 10". It is to prevent from using hi-revs heli motors. Again, I am not sure if it is necessary.
But it works fine.

I've read a few posts concerned that this plane will not penetrate well. If it flies like any of my AG foiled DLG's, there is no reason why it wont penetrate well when trimmed and flown correctly. I almost never balast my DLGs and I usually fly in wind of 10mph plus and have no issues penetrating or coming home. This model should respond well to camber changes. I just recieved mine in the mail. Going to top drive the flaps and ailerons to clean up the bottom of the wing, and almost 300W of power input. I'll post pics when shes done if anyone is interested.

Flying Report?

I wonder if after 6 - 7 months from the last post (busy building), if there is a flying report on this glider.

It would be good to know about flying performance and how underlying light components, specially wing and tail, are holding out.

All the best,

Luis

Flying Report

Hi

I finally had the opportunity to fly the Q11 in our 2nd F5J contest today.

Conditions overcast, 22C with drizzling rain on and off through the contest
consequently little lift. Rate of sink in the glide was 0.55m/s, with 200m
climb in the 30 seconds allowing 365 seconds of air time. With a little
very light thermal? activity I was able to in a couple of rounds to make the 10 minute mark.

Never exceeded more than 10 meters height gain due to this lift, more
of a neutral glide maintaining height.

Climb rate with the Turnigy KA20-20L (1050Kv) outrunner was 6.7m/s
with a current draw of 11 amps from the 3S 800mah lipo pack
on a 9.5x6 prop. It outclimbed a new 3.7m AVA with a Nue 1112 geared
inrunner and more than matched it in glide ratio.

Despite what appears to be a frail model,I am very pleased with this aircraft and its performance,
and its ability to be able to penetrate into the wind,
Radians were hovering, this was penetrating at will.

My first experience with flaps, I used the trim for 3mm camber for maximum
float after the climb, and did not have to use reflex at this time.
50% flap had it coming down at a steady rate, and full flap allowed me
to dive vertically and flare at the last second for close to spot landings.

IT IS A GREAT MODEL

regards

Alex
