| James,
I believe NEWHELI is making a good point. Unless they have very recently changed the design of the anti rotation bracket (e.g made them longer), then installed as per the instructions that come with them, you will have a relatively limited collective/cyclic pitch range - one more suited training with a standard 32 type engine then for 3D, specially with a higher powered engine.
I have found on my Ravens and Falcons that if one wanted a +10/-10 of collective pitch range with 7 degrees additional for cyclic or +11/-11 of collective and 6 degrees of cyclic, one would have to raise the verticle slotted part of the bracket. Otherwise when at full collective and full forward (back in the Raven) cyclic the pin would bind at the top, forcing the swashplate down and removing collective. This can make for some really weird responses through some flipping maneuvers etc.
Without changing the verticle location of the slotted piece the only alternative is to limit either the amount of full collective or full cyclic pitch.
If one does not want to sacrifice any of either, then the simple solution is to mount the verticle slotted piece higher on its frame. The slot is long enough to accomodate more pitch range, it is just that in its' stock configuration it sits too low.
To raise it, all one has to do is mount it with the bolt through the upper hole instead of the middle hole. This will mean the lower "dimple key" will then key into the middle hole and the upper "dimple key" will be above the frame and not be keying into anything. The bolt and the lower dimple key are more then enough to secure it vertically. Now the slot has been moved up enough to allow a much greater pitch range.
I covered this here on RR and in other forums a number of times a few years ago.
IMHO, the instructions of the units that are sold seperately as upgrades and the ones that are provided as stock with the Ravens should be rewritten to show the mounting this way.
