The torque factor is from the engine turning clockwise if you're standing behind it.
The model pops back in the air due to wing buffering , the cussion of air between the wing and the ground during landing attemps.
It is more noticable on a low wing models of course.


A bad habit to develope with a trigear trainer is to push down on the elevator right after touch down to prevent the model from flying again
becuase you came in too hot. You can get away with it on a pave or smooth runway, but on dirt or grass you're helping the nose dig even more.
Or you came so hot, it smacked the ground and pop back up again That's okay everyone has to learn how to flair sometimes or somehow.
Or you pulled too much by increasing the AOA, so the model will just drop, then smack, then pop back up.lol
If you push on the elevator after touch down on a trial dragger...you must have purchased a collection of props and enjoy the art of repairing
your vertical stab

A tail drager is almost in a prefect 3 piont laning posistion, depending how high you install the tail wheel.
A good instructor will have instructed you to alway trim the model slighty nose down for landing procedures.
You increase the aoa slightly to slow the model down, then flair, then stall it for touch down.

A tri is not in a 3 piont landing posistion , due to simple fact the you must stall the wing or AOA of the wing.
Unless of course you think you're on an aircraft carrier doing a harrier.lol They have cables and hooks to stop the aircrafts though.
Plus nice shock abosbing landing gears.
