I'm glad you've done well with the SuperCub.

That you have, speaks more to your own tenacity than anything else.

But it is not a suitable plane to recommend as a trainer.

I've already gone into the reasons for all of this at length, so it does not bear repeating.

As I've mentioned, it is NOT accepted for certification, which alone points to it's unsuitablity for a newbie. Note that other electric planes ARE accepted...

By recommending it to a neophyte you may be forcing them to then go out and purchase another plane to start their training and certification with.
As such, it becomes a needless expense.

I've seen too many people arrive at our field having made this mistake thanks to a poor recommendation.

It may be great for someone who will fly in their backyard, and only in light breezes, but few newbies interested in RC flight limit themselves so much.

You may not like to hear this, since you enjoyed yours so much, but it doesn't make any of this less true.

There are other much better planes for the neophyte.

e.g. RCKen's list.
