Hello,
here is the pictures of the new SKYFIGHTER based scratch built plane, waiting to maiden. Used Thermocole and depron and coloured packing tape.
Electronics:
Assn X8 receiver
1300 3 cell 25AH
9 gram servos
Little screamer Parkjet with 60X40
30Amp ESC.
AUW with battery = 448 grams
Hope it will fly well. Will post some videos later if it flies well.
Best regards
ashta
As usual.. another wonderful build Astha.

thanks for the kind words ismail.

Nice {:)}
Wonder why more people are not using magnetic latches for locking their canopies. They are simple and efficient.
nice model :), i see you like delta wing models a lot wounder how may of then you have ( I'm guessing 5 or more )

thanks sahilkit.
I started this hobby 2.5 to 3 years back. I know only electrics. Must have made > 40 different scratch builts. Not necessorily Deltas. But Deltas do fly well in wind and easy to carry.
pl see one full coro regluar plane i had built soem time back
thanking you
ashta
I've built the exact same plane in white coro and its still waiting for completion of the firewall. Can you post pics of the firewall and what was the weight and motor/battery specs for your plane?
oh i remember that plane i have seen it at indiarc (if i remember correctly )
nice stuff,why can't you post pictures of all the 40 model (if possible).
best

Looks like a profile Yak-54 (except for that cockpit bit) {:)}
Would love to see some Youtube action with these ! Guess most people are lazy like me when it comes to putting videos up.
Dear Astha,
Cool planes......... could u tell me the auw of ur coro yak lookalike and its powerplant setup........ i've built a similar model from coro and the 1050kv outrunner that i use seems underpowered - read unable to take off.
What prop size do you use?
prop -10X6..... batt -1800mah 3s1p25c 30A esc....

Isn't the wattage of your motor one of the key issues here (along with the prop selection) ?
its roughly 150w and my model weighs 1250g
At 1.25kg thats a flying brick - what spadders call the heavy weights. ;D
just curies, 150 watt motor on a 1.2kg plane is it not over kill ?, may you should try one of the Saju's calculation or i would say go for a motor with at least 400watt or more power
sahil
thanks people, guess i gotta go get a 400+ watts setup then or perhaps a 0.46 glow :)
No. Instead first lighten the airframe itself. Otherwise the plane will still not fly well. Any idea why the frame is this heavy?

The specs are as follows. Later i also tried the DT750 Hextronix, motor from hobbycity. as in photo
WS = 35.5",Aelerons = 4"x2". Length = 40". This was made with 2mm coro. Almost same as UCD3D in terms of dimensions. TR 35-30C motor 1100 KV with 10x4.7 prop. 30A esc, Gws rcvr and 9 gms servos X 4. 1800mAH 3cell Polymax

You can post them here by just bringing them down a reasonable size (http://www.webresizer.com helps!), and then attach them to your replies 4 at a time. So keep on "reply"ing to this thread, and every time attach 4 pictures.
But it may cause the thread to load slowly on people without high-speed connections though, so you may want to do it in like 3 or 4 separate threads like "Ashta's scratch built models - 1", "Ashta's scratch built models -2" and so on. In each thread, reply 2 or 3 times to yourself, and attached 4 photos each. That we will have a manageable 12 photos per thread, instead of all 40 in a single thread.
You can also point to them in your thread, if they are hosted in other sites like Flickr (instead of attaching them here again).

her is the video of the maiden+1 flight. Thanks for watching.
Sorry i could not show you a scremimg skyfighter since i was flying only at about 40-50% of throttle. Just wanted to get some familiarity before screaming.
its a great stable responsive flier... thanks for all the support from this forum.

Congrats on the maiden. It is indeed a great flight.. :thumbsup:
Hi Ashta,

dear Anwar,
i just assembled this model once again to take a video. i took the video myself while flying using my crude cap camera. so the frames are not good. (I forgot to turn my head and not the eyes while taking the video with camera on the head !!!) aslo i am not a great flier. pl excuse me. It is a very gentle flier can slow down nicely with out tip stall. AUW is about 850 grams. thanks for watching.

hello,
i have been flying this plane in atleast last 10 sessions. It has become my most favourite plane.
The speed envelop is amazing, similarly the stability wonderfull. Inverted is sooo easy.
I would recommend to build this and find it out yourself.
here is the link.
http://www.rcgroups.com/forums/showthread.php?t=1087472
Though i made changes in the material (Used thremocol instead of Depron, whereever possible) to make it lighter.
As Anwar suggested, i have made avideo to see the wrking of the plane closer. I had to connect the battery one handed since the other hand had the camera.

You are making me want to retire early ;)
BTW, I noticed that you are flying inverted, yet only just closed the battery hatch without significantly securing the battery (unless you had Velcro, which I may have missed) :headscratch:

Yes Anwar, you do notice things however minute....
The magnets are so powerfull and i use totally 4 of them. I have tried shaking the palne inverted and ensured that Bat does'nt come off. So did not use Velcro...
One bit agressive flt with my Skyfighter

Hello,
After about 40 flights on my Skyfighter, it crashed badly while trying to do a reverse loop and sun directly on me. It hit the ground with full speed. see the photo.
It was so nice a plane that i wanted to make on one more and started on it asap. (This happened 10 days back)
R.I.P skyfighter...
Pity! She was such a wonderful flier...............
