EPP F-86 saber

I am making saber with EPP.

It will be...
47" span.
1800-2000g(4-4.5lbs).
Thunderpower Gen2 2100 5S2P.
Midifan, Mega22/30/2.

I wonder whether it can take-off on lawn and fly well or not.
What do you think about that?
I will attach some pictures later.

At that weight and power level you should be able to ROG on concrete but grass is another matter. It would depend on your wheel size and how tall the grass is. You may want to reconsider your flight packs, the 22/30/2 in a Midifan pulls over 50 amps. You might need 3P on the lipos, but may get away with 2P if you limit flight times and give plenty of cooling air. I'd still be careful though. I use 5S4P on that setup and have puffed cells due to long flight times, lots of full throttle usage and limited cooling air.

Thank you, Ed.
As I konw, Thunderpower Gen2 is 10-12C, therefore It will be 42-50A. I will manage the throttle as 50-100% carefully.
And I will be careful about flight times and cooling air system as your advice.

Sometimes things seem fine on paper, but in actual use you get less the expected results. 10 to 12C with one cell out in the open, but start stacking them and reducing their ability to expel heat and things are different.
