| The T-Rex is not a good candidate for indoor flight. The high headspeed will lead to furniture/household damage.
If you are looking for an indoor heli, go with a small fixed pitch heli like the Hummingbird or Piccolo.
I HAVE hovered my T-Rex in my basement, but it is much more enjoyable outdoors.
As for negatives, there are three areas where my brother (also a 'Rex owner) and I have made fixes:
1. Swash ball was too tight. Heat up a soldering iron, touch the ball with it until it is hot, wiggle it while it cools. Presto, friction free. If you blow it buy heating it up too much, you wanted an aluminum swash anway, right? :-)
2. Elevator ball links at the swash and washout ball links at the swash are too loose, allowing slop. Fixed in a matter of seconds with a lighter. With the Link off of the ball, wave a lighter across the outer face of the link. After a second or three, the plastic will heat up and just start to puff up around the edges of the socket. Let the link cool, and reassemble. If there is still significant slop, repeat.
3. Knee joints on the washout links too stiff. Push the pin out and slightly ream the hole on the upper arm. Use either the pin, or an appropriately sized drill bit.
1 and 3 above added removed a lot of the friction and binding in the system. 2 removed a LOT of slop. I flew without these mods for 8 or 10 flights, hoping that the joints would 'break in'. Cyclic response stayed 'mushy' and delayed. We went through, dissasembled the head assembly and checked everything. When we were done, and we re-adjusted tracking, we had a well behaved heli. |
. But there are lots of things you can do to get your flight times up significantly. Look through the posts for ideas about making it lighter.
