every time i said ESC i meant EDF sorry
In theory yes that would add thrust, but the amount of weight would of the heating system would be more than the amount of thrust you would be adding. A hair dryer can only heat to about 140 degrees F. turbojet exhaust are at around 2300 degrees F and ramjet engines are almost at 4000 degrees F.Wait if i disassembled a hair dryer and soldered the heating element to my motor wires and then put the heat part on the back of one of my ESC's wouldn't that add a lot of thrust as the air coming through the ESC would then be heated causing it to expend and be expeled out the back more rapidly????

No, the thermal energy you could impart to the flow of air would be next to nothing and destroy your ESC/battery. That why heating your house is about the biggest expense of a household bill. That's why reheats on jets engines are only used for short bursts as it eats fuel, even though jet fuel is 50 to 100 times more energy dense than batteries.Wait if i disassembled a hair dryer and soldered the heating element to my motor wires and then put the heat part on the back of one of my ESC's wouldn't that add a lot of thrust as the air coming through the ESC would then be heated causing it to expend and be expeled out the back more rapidly????

See...you could try making a edf afterburner but is is going to be heavy and complex.
There isnt much you can do to make an edf better besides putting it outside the plane so you dont have to deal with intake and exhaust tube drag.

Love the look of t-tail designs. Yours looks to have good handling, it banks clean and looks locked in. Nice job👍Got to maiden a new design I am working on.

Flew great!!!
Installed the prop adapter on the FT bronco, took it outside to test and check battery life. Ran it up and got tons of vibration. Balanced prop, still shook. Prop adapter is off center by maybe 3mm. How can something turned on a lathe be off by 3mm? Remembered why I took up slope.
