Unless you have a large totally open back yard 2 acres plus, I would not recommend the electrajet and I would not recommend it for flying in streets among houses. It will be too fast and too hard to control.

If you already bought it, you will need to launch and get it way up in the air right away. As long a you are high enough, you should be OK.

Something like a GWS Tigermoth or a Slow Sitck might be better.

With electrics, weight is everything. 1800s may be oK if you are going to fly fast, but for slow flight, stay with the 600 mAh packs. Maybe 800s. The heavier it is the faster it will need to fly.
