Anyone tried to used X-UFO rings on DF? If so how did it go? I was thinking about swapping the rings so I can protect them blades on my DF IV.

The XUFO rings are too small to use with the DF, also many XUFO flyers have reomoved the rings because they make it harder to fly.

Also with the new blades... you won't need to worry about protecting them!

Thank guys....I just got my DF IV today and I'm a newbie. Any tips on the DF IV I should be aware of? The only Heli I had exerienced with is the Xufo. Controle wise is it a different beast compare to Xufo? This is the first time I have ever spent an expensive to like this.

Did you get a DF IV or a V? Is it new or used? (Can you even buy a new DF IV any more?)

Anyway, be sure to check out [link=http://www.rcuniverse.com/forum/m_3676146/tm.htm]this list[/link] of postings from Sky High and others regarding the DF V. Some of that will apply to the IV as well, if that's what you've got. A user here, Greasetattoo, has a IV, I believe.

Assuming the IV is just like a V but without Thermal Intelligence, the main piece of advice I (also a relative newbie) can give is: Remember that you're flying any time the rotors are spinning! Even if you're still on the ground. And before really trying to fly, be sure to do the "trim hop" procedure (preferably, on a reasonably soft surface). The "trim hop" procedure means briefly giving the DF enough throttle to get slightly airborne and then putting it back down on the ground. Note its tendencies (does it like to yaw left or right? nose down/up? roll left/right?) and trim them out to the point that you can "hop" pretty much straight up and down with just the throttle and the stick centered. That will make your first flight much better.

If you have the old, white nylon rotors, remember they're pretty delicate. Laminating them with packing tape has proven to be a good solution to making them a bit more durable.

Another piece of advice from someone whose first four-rotor machine was also an X-UFO: The DF is capable of far more extreme attitudes than the X-UFO is. Assuming your X-UFO is stock, the "flip of death" occurs once you get more than about 20 degrees deflection in attitude in any direction. Not so with the DF! That can be a bit startling at first. You think you've "lost it," when in fact the DF is still quite controllable.

Good luck!

One other thing, a major difference from the X-UFO: Again, assuming we're talking about a DF without Thermal Intelligence, remember that "stick center" does not mean "return to level." It just means "hold attitude." So if, say, you've pitched forward, the DF will stay pitched forward until you bring it back to level by applying back stick. Same with roll. (Yaw is different, though: The DF should stop yawing as soon as the yaw control is centered.)

Thanks for the tips Will.
I bought a refurbished DF IV. I thought it would be best to start with Xufo b/c it's cheap and I wouldn't mind if I crashes. Planning to have a graduation party at my house and video the scene from above. I'll probably will have more questions after putting DF together. Great site and awesome people in here.

You're welcome, Design1! Good luck, and you're right: There are a lot of great people in this forum! I've learned a lot here and I'm sure you will, too. Don't be shy with your questions!
