Hallo G,
thanks a lot, first of all I wil not play with the ParConv for a while.
You might not remember, but some days ago You gave me advices to try Masouka's tools instead of Möllers ParEdit_8 V1.
Now my first FMS model, is flying with 7 .par file quite the same way as the RC model.
But the fact, that thre are no (or only some) limits of physics are taken into consideration at FMS, if 7 .par is used bothers me. Therefore I have already tried to copy and modify 8. par file of an existing model, but the result was wrong.
I will do again.
On the other hand there are two things which have to be explained.
First, sorry but without Your consent, using the ParEdit of Masuoka, enlarged the prop diameter value of Your alleycat (I have downloaded alleycat some days ago to see how a real fast model can be controlled). Nothing has changed as far as the maximum speed is concerned.
(By the way my model changeing the trust to 100, instead of 2, Newtons flies faster but this is not an acheivement but a problem or bug of FMS)
This can be expected with a real model (more or less; the effects are not linear), because the power of the motor is not enough to drive the larger propeller, but if this is true than more constrains are taken into consideration by FMS V8.5 if 8. par file is used. This might be the one of the reason of development of FMS 8.5.
On the other hand You said to somebody that as far as 7. par files are concerned even if .X file is the source of geometry only the CG is taken into consideraton as far as the positioning of the model, in standstill on runway is concerned, and the collisions with other objects has to be calculated.
But there are two facts. I have created my FMS model by Metaseq.
recently inserted a propeler, (it is an e-glider), and now the model is sitting on the ground, and the edge of the propeller (and the endpoint of the tail) is touching the runway, and loading the model into ParEdit_8 a lot of collision points are shown, those have to be taken from .X file because the 7 .par file has no data about them.
Has it been changed, and the definition of collision points are automtically taken by FMS as well, not only by the ParEdit_8?
You have said that since Your tutorial on 8 .par files was created a lot of things has been changed. You mentioned Paredit of Masuoka. But ParEdit of Masuoka has nothing to do with FMS only a tool to create 8 .par files.
The ParEdit_8 was developed by Möller, and if this program can calculate collision points automatically, it might be the same with FMS 8.5.
Best regards,
Laszlo
