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.

Nice   

Wonder why more people are not using magnetic latches for locking their canopies.  They are simple and efficient.

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. 

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).
