Doc Nayeem: you've been making out with plenty of hot models yourself 

so the new wing chord looks like a inverted simplex airfoil  wait you said the wing bottom part should be parallel to horizontal stab.

Sanjay sir, no words! Your building skills are unparalleled ! This one is a chic ! Love it!💖💕💘💘💘💘

Repeating the question posed in Reply #4 above:

So my question, dear reader, is do I try to keep the wing C/L parallel or leave the flat part parallel? Waiting to hear the views of experts and non-experts alike  Wink

Didn't respond, as with your experience you know what will happen in either case.

Instead I'll tell you what I did with my Sunbird, which, with a flat bottom airfoil, was loopy under power.

Since I didn't want to add nose weight, or reduce the decalage, I mixed 10% down elevator with throttle.
Works fine!

Thanks Sanjay Sir .... Inspired by you ... But the beauty, accuracy and speed of your builds are hard to match ..

Thank you S174! I hope it flies too

Interesting. But I think I will first try as it is (likely to climb) and then add packing under TE if climbing is excessive. Let's see

I guess it's difficult to predict the exact change in behavior - the slightly semi-symmetrical wing will reduce lift compared to the flat-bottom, and the increased AoA should compensate??

Hey Doc! Thanks!

Sahilkit, keep  away

That's probably the most likely scenario!

BTW, sir, every time you produce a new model, I get encouraged to shake off laziness and build a new one too. Must be having the same effect on many forum members. 

Waiting for your builds Iyer sir 

  i think either wing setups should work provided the angle to attack is adjusted.

Edit: Sanjay the smallest rc plane you built in coro?

Sahil

This a message to sanjay sir: (really guilty)
To sir,
i gave up on spads after crashing the avi the 6Th time.    
Thank you.

P.S-I think my avispad ( air alaska N7572) has been petrified by the ghost of the spads.

@sanjayrai55 sir,

Thanks for the encouragement.

This is what I managed tonight.
If I do build it in the next two days, will post a separate build log.

Not bad for a sketch, eh? Even looks recognizable (I hope)

Sahil, the smallest I've built is the QB 10, 39", and highly aerobatic: everyone's favourite on our field. In fact, I've built two of them  . Uses the same power system as the Junior 100

Iyer sir: that model has no business on the drawing board! Put 'er in the air 

Prabal, these things are normal, and not anything to get worried about

I suggest you build another one; just stick to the plans, and make an extra effort to build it true and square 

allright sir!
making a piper cub now!

Don't

Make an Avispad, and make it well

As usual...Maestro at work..Another masterpiece in creation.. Nice Sanj!

Thanks Dee

Just remembered there was no video in this log 

Rai Saheb .. 

Not a good landing though 

supreb sir !
