There's nothing wrong with getting the SE as second model.
It dosn't have any bad tendency. It's design to fly at a lower speed and be toss around.
That's what dual rates are for.

Just use the same procedure as you did with your trainer.
I seldom fly a new model on it's maiden flight to begin with anyway.
My instructor love's me. Me breaks in all my models. Put it through the pace,
2-3 more flights depending on adjustments require to dial the model in.


Just fly that thing at 2-3 mistake high until you get comfortiable with the model or any model.
Have someone stand next to you incase you make mistakes...but at 2-3 mistakes high ?

Most of time I crash my models is taking changes and showing off at lower altitude.

The SE lands like a kitten on low rates.

It'll be easier to tail drag off of grass anyway.
If you're not use to tail dragging..just take the wing off and practice taxing or punch it for take off less wing.

Havng said that..I've had more than hundreds of flight just decicate to landing proceedure, dead sticks, touch and go, or proceedure turns.
mmm...also trying to froce my trainer into a flat spin too or a water fall as trun around, inverted 5' off of the deck.lol
I'm somewhere between free style and a pattern flyer.
As I said most of my crashed comes from showing off, bascially doing maneuvers that wasn't thought out.

it depends what type of flying you have been doing on your trainer.
