Title: Small 20" wingspan plane from scrap Biofoam!!!!!!
Post by: ashJR7202 on November 21, 2010, 12:07:15 AM
hi guys!!!!

completed my F-15 and working on 30" yak, mean while i had lots of pieces of Biofoam with me, u can say scrap!!!!

so instead of throwing it out, i decided to make small plane out of it!!!!

it has got 20" wingspan, motor 1811, 1800 kv 12gms, 2x4.3 gm servos, will be using 220 or 360 mAh 2s lipo. and hopefully will be able to maiden next weekend!!!

wing, elevator & rudder is made up of 3 mm biofoam and fuse is from 6 mm piece. both wing and fuse is supported by CF.

no plans as such just approximate ideas and experience!!!!!

lets see how things work out!!!!

flying or crashing!!!!!!!

Ashish

Hi Ashish,
Pic178 is a great and true mechanical idea of putting servo and controlling the airlons.
ANOTHER GOOD WORK FROM GREAT ASHISH..a true foam builder....

Your Aileron setup ROCKS!! great work dude!!

Do post the maiden! I would like get get feedback on the  heat formed under chambered wing you have. I have exactly similar wing and I wanted to build a slow stick with that.

Food for thought... shouldn't the lower part of the wing also be covered, to reduce drag ?  The top has the nice airfoil shape, but doesn't  leaving the bottom bare cause issues ? :headscratch:

These kind of Aerofoil mimic 'Under Chambered' Aerofoils and for smaller models and provide much better lift cofficiant than flat/profile wings.

Just see the wings of the famous Binary DLG Glider, now available with HC:

But the downside is that they don't have good stall characteristics.

Great effort Ashish!

I like the wing construction. It's really nice. You will get good lift. The airfoil shape you gave is perfect. Take a flight and post the video link asap. Really waiting for maiden flight.
Great work........

Hi Ash

That is nice little plane you made...the aileron servo mount is very cool idea..just made a full fuse foamy..and have scrap foam left..i think i will make a small plane like yours. Now looking for a flex printing shop near my area..would want to make my plane as beautiful as you make yours :)

hey, thanks guys!!!! sorry yaar couldnt maiden it yet!!!!

took week long leave and went to my native Nagpur, some personal reasons!!!!! so hopefully will be able to maiden it this weekend at Airoli!!!!

about airofoil shape, i saw this kind of shape in some plane, and found it easy to build compare to others, so didnt think much abt it and just constructed this, not sure how will it behave, will update once i maiden it!!!!!

once again thanks!!!

Finally, last week, i was able to maiden this plan.... {:)}

had lot of wind  :banghead:, but couldnt help myself, so decided to maiden it, whatever happens!!! :'(

and asked Sandeep to launch it, and wow no crash, i try to fly it but it seems like wind was flying it, but somehow i managed to land it without any damage!!!!!!! {:)}

Post by: avishekghosh07 on February 10, 2011, 06:52:17 PM
nice control Ashis!

If there is heavy wind then i think it would be better to cover the bottom part of wing.
but overall .....it's flying good.
