Thats what make you different from the rest of us dear Ismail bhai :)

The H-stab is sturdy 6mm (for obvious reasons :D ) and the V-stab is 4mm. I do have flutter at full speed on the ailerons. The aileron servo placement is very close to the fuse plus its is a cheap HK mini. I was thinking about changing these with Hitec 425BB (which I have) and might move the aileron control horns a little far from the fuse. (By the way, during the maiden it was horrible at higher speeds and I cut "V" on both aileron ends which helped a bit.)

And about the CG, I intentionally had it nose heavy for the maiden flights. Last day I removed just about 50g of weight from the nose bit by bit after each flight. Like you said, its still a bit nose heavy as you could see from my hover attempts and the need for elev pushing during slow flying.

I truly value your comments and is seriously thinking about adding tail braces just to be on the safe side. Next time at the field, she will be more on the tail heavy side for sure :)

Sameer.

nice flying man...dont worry too about flutters in corro models.. its unavoidable.. just fly slower..
check out my version of the plane.. i made one wing which still exists n all the fuse i made either crashed or abandoned due to over weight.. power to weight 3:1 n flight time hardly 3-4 mins but complete adreneline rush..

i ll send a link for remaining.. 200kb limit is too irritating..

Sam some good flying there, you landing have become 'Makhan'. you can make out that she is nose heavy for 3D, i am sure you have corrected it
Gusty's Hangar and Introduction.

A Good pilot will practice until he gets it right,
A Great pilot will practice until he can't get it wrong.

Good job alam! Do you have a link to the build? and thanks mate :)

Thanks a lot for your kind words Gusty bhai :) That was the second time I take her out. Slowly reducing nose weight before each flight. Hope to bring it where I wanted by next couple of flights :D

A lousy attempt to build a canopy using foam from a computer packing box.

Looks good to me!! do take a look at 1 liter mirinda bottel, it has curves suitable for building a canopy :thumbsup:

Thanks Sunlikestar, will give it a try :)

Nice build and super flying Sameer! The landing is indeed very tempting :) Can you please elaborate a bit on how you made the bolt system for the wing (with pics)?

Thanks Vishal! Will upload soon.

As you could see per below pics, there are two 8mm dowels on LE side which locks into plywood slots inside the fuse. At the TE side, its a single HK 6mm nylon bolt which goes into a 6mm blind nut.

Let me know if you need more info :)

Thank you Sameer! A pic of the lower trailing edge of the wing would be appreciated. I guess that's where you insert the bolt.

Edit: Sorry! Didn't know you were still uploading the pics! Got it now!

excellent spad design,
i have decided to build my first foamie, but your spad build inspired me to try coroplast build first.

how did you get the rounded shape behind the canopy leading up to the tail. ??? ??? ???

Hi Sagi,

Thanks a lot for your kind comments. My build was basically based on the actual balsa plans for "Tweplica". However, I adopted Frosty's VSF for the fuse plan which certainly helped me complete her with out much hassle. You could find Frosty's thread here:

Except for the VSF, I opted my own techniques (bamboo skewers and coro flutes) for strenthening the frame which reduced the AUW quite significantly :) You could easily get the round shape with the VSF (V shaped fuze). Its a fun plane and a real floater at just over 4#.

Don't know how I missed this post earlier  ???  :headscratch:

Great build and great flying Sam  {:)}
