After reading a couple of the threads here in the past week or two and looking at this link in one
http://www.mektek.net/forums/index.php?showtopic=139226 I decided to give it a go.
I have been having stick issue for a few months now and thought I had nothing to lose by trying this as if it didn't work and I destroyed my stick I would need to replace it anyway..
I started by following the instructions in the link (I have two sticks..one that is used for parts) I decided I would try 1 axis first.. What I found is that yes you get instant movement but when I got to 3/4 of the sticks movement range the Hall sensor would loose contact with the field and jump back to center..after spiking to the opposite direction. (this may be ok if you have done the mod with the plastic disc to spring as it cuts down the stick full movement)
After finding this I decided to put the old bracket back in and use one magnet (remembering I have spares) stuck directly below as in the link...I now have three magnets (one each side and the middle one) this helped the spiking back to center and the stick was very sensitive.
While I was doing all this I dropped a magnet close to one of the brackets and it placed itself on the outside which gave me the idea to place a magnet each side...so now I have four magnets on one bracket. Now I had an axis set up with three magnets (manget either side and one below hall sensor) and one axis set up with four magnets (two either side of the hall sensor)
I flew with this..hahaha if you can call it that..... Both ways made the stick move sensitive but I found the axis with the three magnet set up harder to scale.
My findings over a few hours of game time this weekend
The way set out in the link works (for stick sensitivity) but there is quite a bit of mucking about to get it in place and centered (not alot but still) and the stick movement would require so form of adjustment.
Using the bracket installed in the stick and adding a magnet in the center under the hall sensor fixed the issue with stick range and spiking back but as for above required a bit of mucking around.
Adding a magnet to either side of the bracket installed was easy (just drop the magnet close to the other and it did all the work for you) gave good sensitivity and was easier to scale back
( I am ham fisted and with this instant movement I was really over doing things)
I am still testing this new set up and now have both axis set up with the four magnets...I am getting close to being scaled to my way of using the stick but it was a very frustrating time had doing it...If you plan to try these things expect to die...and get in there, as just flying about will not give you the feed back you need for your adjustments as I find anybody can fly about and keep things good but during a good fight you will be concentrating on other things and your hand will not be one of them.
So all in all...the extra sensitivity has allowed me to add a little dead band to help with a little centering issue I have with my stick. On inspection though I think this issue is with the plastic seat at the base of the spring more than the sensors...
But the sensitivity is better..no dead stick movement.
Please remember this is what I have found for my own personal set up and don't have anything substantial to back my findings.. I just thought it could be of some use to some of you and could offer an easy unobtrusive way for you all to trial
I have no Idea if any type of small magnet would do the job but if you have a spare stick you may find it a viable test for yourself.
