Nice  {:)} 

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

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.

Isn't the wattage of your motor one of the key issues here (along with the prop selection) ?

At 1.25kg thats a flying brick - what spadders call the heavy weights.  ;D

sahilkit

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

martian2121

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).
