Dead weight added before median to get correct CG. :banghead:
Thanks to Prady sir without him it was not possible to calculate correct CG
Plane was too tail heavy, so added 8 AA cells approx 200-300 grm in front of plane, this cause performance of the plane but defiantly help to fly properly.

Happy landing  {:)}

Temporary landing gear show there weakness , but was strong enough to save lipo mounted at the bottom   :)

This was amazing experience to see my scratch build flying so nicely in first attempt.

VinayakR

One thing I notice and would like to share/ suggest all beginners like me

:salute:Please visit your nearest field and senior RC flying members before you start with your new plane. :salute:

I have made mistake with my first scratch build BlueBaby 24" I tried it myself and never succeed. Every time tried to get into air it crashed on nose.

Without senior members like Pradi Sir , Amar Sir , Mohan Sir and Amit It was not possible to get my new bird to air.

Thanks Ashish.
As this plane was a quick build (almost built in couple of days) instead of waiting for exact build material and delay test flight I decided to go with things available with me (this specially applies for landing gear)
Sooner I'll be changing this with actual lighter foam wheels.
