Nosewheel steering thoughts........
Guys,
Forgive me I am still learning!
Right,
The model I'm building a BVM T-33 with Super Bandit landing gear has two servos linked by a JR Matchbox to control rudder and Nosewheel.
When take off finally happens and the gear is raised, the BVM nosegear steering arm ( fork like assembly that latches onto the oleo) automatically releases from what I see, thus the nose geer cannot be steered whilst retracting into the well. I am assuming that once flying both servos (rudder and nosewheel) will still move, but as the mechanical mechanism has released, the servo has no effective load.
The gyro has been reccomended for ground running as the T-33 has a narrow track, so I guess a mix to the gyro most useful to either turn it off once the wheel retracts or reduce the gain, so that whilst airborned the rudder is only controlled by the pilot (allegedly!). When I am ready to test, I will need some advice of how to set that up with a JR PCM 10X!
However,
Hypothetically if taking a cross wind landing, loads of larger rudder movements etc , and then hit the gear switch, it is possible for the nosegear to come down, and the fork to miss the relatching on the oleo preventing turning and possibly worse, forcing a particular turn.
Like I say I am learning so I am not sure if this actually possible to do and I am worrying about something uneccesarily, or if it can happen, what can you do to reduce the risks?
As I said before the really dumb question is the one not asked, so I don't mind asking some questions that are stupid!!
