Your heli experience will give you some advantages in learning to fly fixed wing, since the fixed wing and hely fly similarly if you compare level forward flight.

That means you already know how to deal with control reversal, and can probably do well at flying around the trafic pattern.

Learning landing on the other hand... its a whole different approach.

Also, the fixed wing plane tends to fall out of the sky if it quits moving forward.

To land:
The heli you fly in above where youwant to set down, convert to hover by pulling the left stick back, adjusting collective and then pushing the left stick forward (again adjusting colletive) then just hovering on down.

The fixed wing you fly with the wind reducing power, judge when to make the 90 deg turn to base leg, pulling power back more, then turn to final, and may pull power back all the way to idle, and guide the thing smoothly onto te runway. You have to remember to maintain flying speed... and you have to be accurate in you judgement of when to make those turns in order to put it on the runway smoothly.

2 different skill sets. (both only summarized...)

The U-Can-Do will probably not give you problems anywhere but landing. Its not something I would have recommended... but, I'm sure you've seen the normal trainer model recommendations and you appear to have decided not to bother with one.

I strongly adise getting some help leaning to handle stalls and landings.
