Ready to fly. (Used scrap pieces of Red Vinyl temporarily to help with orientation) Will make graphics later.

Flew 4 flights today. The model was a little underpowered and would start to drop below 60% throttle. Apart from that, it is a wonderful model. Flies like a Sport plane and flies pretty fast.
Considering that I redesigned the entire fuselage and empennage, it is no longer apt to call this an AviSpad, hence after seeing it fly, it has been renamed to AviSport.
Flies inverted very nicely with very little down stick. Also rolls and loops nicely, however these were slightly restricted due to the lack of power. (I plan on putting a slightly bigger motor)
All in all it's a wonderful plane.

You have not mentioned that you "ün-designed" on the spar height; the thin wing is making it behave so.

Yeah, but it didn't affect the lift and stall characteristic much. The glide is pretty decent

Very clean build Maahin. Have you blunt the leading edge?

sanjayrai55

Of course it affected the lift! That is why you have to fly with high throttle

crazycalvin

Haha, nice flying! Miss Sanjay sir's commentary :)

Upgraded the motor to NTM 28-36 1400kv with a 9x6 prop. The plane flies normally at half throttle now and pretty fast at full throttle, further living up to the name "AviSport"
Loops are now perfect as the plane has enough thrust to go vertical.
Getting 5-6 minutes of flight time with a 2200mah battery.

@Mjet
Sorry sir, missed your question.
I made three scores for the leading edge to give it a slightly rounded shape.

Update:
The new motor really has given this plane a new life.
Inverted flight is very easy at 3/4th throttle with very little elevator required.
The plane can climb vertically for as long as you want. Can do as big loops as you want.
Rudder authority is also good and Stall turns are easy to perform.
Slow rolls will require a little practice, however only from the pilot's side (Need to figure out the exact amount of rudder required). I am yet to try knife edge on this plane.

Glide is decent. It's not as much as the AviSpad, Bixler, Easy Star II etc. But it is equivalent to the Seagull 40 Low Wing Trainer (which I'm used to flying). Hence I did not face any problem there.

Plan 2: Is the fuselage width 50mm or 5mm as shown?

Re:

50mm. 5cm Sorry, I'll fix that in a while.
