Hi Dean,
It was a great pleasure to read your answer to my question. I used to read your articles in Model Builder magazine during the very early stages of my involvement with R/C.
Now that I'm older

I still have lots of questions, that I hope to be answered here.
Actually I don't own an Oxalys, I used to have the smaller version, so it is not possible to test the model. I thought that the T canaliser's role was to direct the airflow towards the tail and make the rudder more effective. I did not know that there were pitch coupling issues with that model.
To be honest I like the designs that have the canopy towards the engine cowl, like Oxalys, Integral, Evolis etc. in older designs the canopy used to be further back. Do you think that Oxalys' tendencies are due to a wrong location of the canopy?
Regards,
Nick
