Electric park flier will cost you the same, as a glow trainer. But definitely, you can start with Kyosho electric EP CESSNA180R TRAINER M36.
If you have kids (son?) and you have ever done toy cars, boats, and model planes 25 yeas ago, you will be in this hobby for a long time.
Try to explain to your wife, that man could do so many ugly things, that RC hobby is much less harm to the family budget. Just do not start with jets and she will be on your side.
