Is there an RTF that will fly in a backyard?
There are no RTF's that you can fly in an average size backyard...Only ARF's and a few kits.
The Tigermoth is a great one and my favorite of all that I've had. I think I had 2 or 3 of them a couple months ago...
You can get the flight pack for about $90 plus $10 for the crystal...Then add $15 for a charger and $55 for the airplane. That's $170 assuming you use your Tx...That's also about 2 hours of assembly.
Flying that 'moth out in the street on all those calm summer nights last year is something I will always remember. I'm not sure if I have ever had as much fun since...
