@shijin ps
Sir,
10x4.5 prop with 3s battery on 1900kv motor will probably draw far more than the rated 15amps continuous. May need to use 2s and/or smaller prop.
Check with a wattmeter if you have one. Else run for a few seconds at full power and see if motor gets hot.

As the control surfaces are huge, keep throws to a minimum, else will be too much to handle!

Best of luck.

@shijin ps
Still probably too large.
My 2826 2200kv runs a 6x4
Remember your 1900kv will run at about 20,000 rpm on 12v
Strongly recommend use 2s only with your existing prop. Check for overheating. May need to go down to 8x4 even with 2s. (Or 6x4 / 7x4 with 3s)
A lower kv (1000-1200kv) motor (in 2826 size) would be required to run a 9x4.5 on 3s

nice airplane build

pls reconsider the balance of the airplane as you put servo receiver and esc all on the right side and for compensate the weight you put battery on the other side

so all these items and battery weight is same then its okay , other wise reconsider the position.

best of luck for the flying.
EAT ,SLEEP , FLY

yup as Iyer sir said need to reduce prop size!!
and from my view , i think the vertical stabilizer is a bit small, but still that wont be a probs here.hope you enjoy the maiden!!
