FSX Motion Platform Experiment

[robcoll]

Hi again ...my name is Rob From Miami....I still have the idea that I can build me a home build Flight motion simulator...after months looking and reading here there and everywhere, it hit me that is not that easy to make this thing work as I wanted...I have been working with this bench prototype for couple of months *..and Iam out of Ideas and there is not help coming from any forum (flight motion simulator forum) that is...except for some expensive ones sites...With basic experience in electronics and a lot in building stuff... Im suffering the defeat of the electronics/software part of it...My test have reveal a problem that I have not been able to figure it out using the x-sim..My platform perform real good until I made a sharp turn(left,right) or a hard pich up or down it will reversed itself 180 degrees...in another word if Iam Banking to ether side to deep ,then three quarter of the way it will reversed itself, now Im all the way to the other side while im holding the opposite bank...

Problems:
I have really have not knowledge of how the FSUIPC works.... except to pick fs interrogate adress that read/send the motion cues and send it to the extractor then down to the converter to math /Axis/g-fornces and then get the cue into the axis...to get answers from the Peter d. fs module in the forum is very complicate and technical..THERE is not much a newbie can learn from bits and peace of information , lack of step by step tutorial from the forum.."that is the Down side"...

Experimenting:
I did when back to the FS-module..and I found out that I can Edit the expressions:
so I started to experiment with it, even doe I don't know what they means...
I toke the Address:0578 (pitch) 057C(bank)and I have changed the Expression from #*360/65536*65536).I know the calculation
of it comes out as a 429467295/360= something like 360 degrees
To #*90/65536*65536).. the calculation result is about 90 degrees notes that I have change the 360 degrees number for 90 degrees...pure logic to me I was looking for 45 degrees movement from center...
then change it to var type 32 that is the only one that send data and register motion with the scaling factor 1 to make it stable...

Result Bench test...
Now not longer my banks and pitch reversed itself...pitching or banking..
now I got 90 degrees of travel from up to down on the axis...!!!!!
not sure is this right?
how can it works now by changing that number..
If that will work in the real thing?
is this totally wrong?

Help:
can someone that know this thing can explain it...
Im really don't know what I did..

Thanks..

project desc:
2 dof fsx motion platform
wiper motor / wall/k8055/sabertooh 12x12....

Thanks..again

Here how I got the degrees..
now let's do some math.

Pitch or bank

Expression #* 90 / (65536 * 65536).
65536 * 65536 = 4294967296

4294967296 x 90 = 386547056640

386547056640/4294967296 = 90

thanks..

Hi rocoll,
Can you gives us an update on your simulator project?

Thanks.
