hovering

[horsham rc]

just a thought.
at what hight do most think me and most biginers should hover at?
i genraly hover around eye level so 5 and half feet but want to go higher so i let the heli climb up to 7 or 8 feet every now and then. what do we all think?

[tiddler]

Don't see a problem with that. Just hover at a height where you feel comfortable

how do you find you 250? how dosile can you set it up

When you get a boom strike the blades fly off very fast. Being in line with a prop is not a good idea. The blades are very large props. Anywhere but eyelevel is ok.

boom strike am i not going to get this on the way down when the heli hits the floor hard? of do you get this boom strike in mid air to...
found this..

boom strike
An incident where the main rotor blades strike the tail boom, often breaking the blades and leading to a crash.
Although the main rotor blades seem a long way from the boom, it is sometimes possible for the blades to hit the boom during large cyclic inputs, as the rotor disk will tilt before the helicopter body follows it.
The most common time for a boom strike to occur is when learning, and the helicopter is landed too aggressively by bringing the collective all the way to the bottom. The combination of the helicopter hitting the ground, and decreasing main rotor RPM give the perfect conditions for the main blades to flex down and strike the boom

so it is posable to get a boom strike mid air. so thanks cjcj i will hover a little lowe or higher maybe..

Like any heli the 250 controls can be set up to be tamer. BUT its small size does make it pretty twitchy, so taming it down too much will just end up making it unresponsive and in some ways harder to fly. They are also more susceptible to wind.
250's don't make good trainers.

The main thing is to make sure you're at least three feet off the ground, to make sure you are out of ground effect - it's very difficult to control a heli properly in ground effect.

getting a 250 for in door flying only and hoping to tam down to my needs.. but thanks for the info.

If your thinking of doing your BMFA 'A' test at some point then hovering at eye level is good practice, the test requires you to hover with skids at eye level so i'd say you have things about right as you are. That said hovering at different heights is to your advantage and can only help.

[coptermanic]

Yes true. A cert flying is around eye/shoulder height, but it's worth varying your hovering height as the heli looks different when above you and when lower down. Good practise of control too.

By indoor flying I presume you mean a hall or something. In which case the 250 should be good fun. but unless you live in a mansion I wouldn't be flying it in your living room

yes indoor club meets hall flying..

Just to add my voice to those above, I'm not long out of the "just hovering" stage of my learning curve. It's very good practice to just hover nice and controlled at all sort of heights, as the perspective you watch the heli at will help when you transition to other areas of the flight (be it forward, backward, etc).

There has also been lots of discussion about what you should look at when learning, I think RAD's school suggests the swash plate. Now for me, watching the swash means you'd have to be quite close to the heli, and honestly, with a 600 size, you don't want to be that close! Also it'd be at a low enough height where ground effect might just come in to it.

It'll also stand you in good stead to learn about your particular heli's pitch characteristics, so do a bit of height varying...keep a close eye on what the tail does. It *should* be rock solid as you increase pitch, no torque/turning affect.

Watch the swash plate Sorry but that just sounds ridiculous to me.
I've always found it best to fly the nose (i.e. You point the nose where you want the heli to go) Makes far more sense. well to me anyway

Yes. You are forgetting fault conditions. My problem was caused when a badly constructed servo failed. When the headspeed reached hovering, the servo moved on its own to one end of its travel. This pushed the rotor disk onto the boom. The speed that the blade flies off is very high, I was glad it missed me.
