is a DC shunt motor satisfy these conditions...????

Answer 1

it depends on what is your requirement

if your requuirement is only fast run for take off, then turbo jet engines will give you maximum thrust for a given weight. but you will require a lot of fuel as compared to piston engine.

piston engine will give you good fuel economy, and thrust much batter then the elecric motor.

another important point is that you might get high RPM from a DC motor but it thrust will be lesser then a combustioon engiiine.

Answer 2

What is the weight and dimensions of the model plane?These are required to answer your question.
