No hawks in L.A. or here.  But here I fly over water (since canals are everywhere) so there's always the risk of drowning the plane if there's a malfunction.

Chased and got chased by the E-Flite Sbach.

snapshots from the video

Got the scanner ready , wanted to go flying today but was not able to go .
Iam using the following equipment
Motor - turnigy g46 550kv
Prop - apc 12*6
ESC - turnigy 60A Plush
Battery - Zippy compact 5s 3700 mah
Reciver- R2008
Servo's - s3004 all around

Have changed the following things
1 - whells (using dubro)
2 - screws (almost all of them)
3 - motor mounting plate (had to make mine to fit the motor)

Techincal specs-
AUW - 2.5kg
Watts - 540 (will use a 12*8 to push it up)
Amps - pulling 32A
Thrust - have not measured yet

Here are some pics -

unpacked some of the scale micro flyers.  more to follow.

This is what I did..

The 12*8 prop has done good for me i was pulling 600w which looks good . The auw of the plane is 2.5kg , this will give me roughly 107 W per lb which should be sufficient . Any feed back and commemts would be appreciated

I noticed that the Phoenix specs for the Scanner mention 1000-14000W 1400W.
Also noticed that you are using a motor rated for 55A, or say 1000W.
My flat bottomed wing SoloStar flies with a .40, which i guess must be 600W at 3/4 throttle.
(Same size, weight and wing loading as your Scanner).
So your Scanner will probably fly with your current setup, but may beg for a one size larger prop.
Best of luck.

@iyyer sir
I do have a 13*4.5 and a 13*6 with me , but will thry not drain the battery a lot faster ? I have only about 2 inch of prop clearance, how much is the least i can do with ?

built this and did a quick test flight

@rajjaiswal92
Sir,
You need to estimate the required pitch first.
From your wing loading, i estimate that your cruising speed requirement is at least 100ft/sec (~110kmph)
From your motor kv (550) and battery (5s), i estimate your full throttle rpm as about 9000.
Or 150 revs/sec.
On a 6" pitch prop that will give only 75fps or say 80kmph.
An 8" pitch will give 100fps at 9000 rpm.
Your 12x8 is drawing only 30-35amps, or 600-700W.
Should be enough for initial flights.
Later you could try a 12x9, 12x10, 13x8. And a larger battery if necessary.
Yes, using more power will drain the battery faster and reduce the duration.
But then what's the use of longer duration on an underpowered model?
If i remember right, Phoenix recommends a 5000mah pack...

But don't worry. Do a short test flight using relatively high throttle.
I am sure she will fly at 100w/Lb. Enough for a test flight.
Your 3700mah battery should surely be enough for a short (3-4 min) test flight.
I think a low pitch like 4.5" on your low kv motor is unsuitable, as the model's speed on part throttle will not be much above the stalling speed.
Best of luck once again. Just ensure she's not tail heavy...


Edit: Sorry folks for clogging this thread. Raj, for any clarifications, please pm me or start a new thread of your own.

i made this....a simple solder arm using locking wire and croc clips

also made a simple two axis camera stabiliser for my quad using two servomotors

Had a great maiden flight , very happy with the way this plane came out . I was worried about the COG but it was bang on , had more than enough power . I did loops , rolls and was tempted to do snap rolls but did not do it . I got a flight time of just above 6 mins (will order a 5000 mah battery )

Ps - forgot to take a vide

Ahmed's first attempt at flying his homemade foamy Curare lookalike.
Claims he had never flown a low winger before!
Model turned out to be amazingly smooth and easy to fly.
Imagine how a real Curare would be...

Smooth and stable flyer. Bit difficult to see; some guy's bald head was reflecting the sun into my eyes 

It was a nice sunday , though the cross winds were very strong . I gave one of my drivers my phoen to record the scanner , but the videos are very shakey . But none the less i have some pics

That's a nice ground you have got there.

after programming the ESC, the skyfun reaches speed of close to 200 kmph! As soon as it passes you have to turn it around or it will disappear out of sight!

finally did the maiden flight of the micro Gee Bee Racer 1930's design. Fun little plane.

holidays are really good!!   , had not flown my gliders for some time now!! the 3 planes are:- parrot 2m, skysurfer v3 and blazer!!

some more!!

I had a bad incident with my sky surfer , the prop broke of while i was in the air and caused the motor to come lose . When the motor came lose the remaining one blade of the prop had eaten the foam around the motor , i have fixed it today will do a test flight soon .

Went out flying with RCParkjets onthe 3rd, this is my qrx350pro in a matte black finish..

Did a test flight and it flew well , had to fill a good anount of epoxy in and around the motor . The aircraft came a bit tail heavy so had to add some weight on my lipo . I dont have flying pics , but do have a few pics of the plane
