Hi
I have had this problem with the nose gear BUT i fox it , it is very easy and has nothing to do with flight direction , well so open the canopy and look to the nose retract you will find the air line which put the preasure to retract it up is been hit with the tray behind it , so what you got to do is make it a little wider by a drimmer between the retract line and the sterring servo very little just to let this line move freely this is what i did and sense that it retracts quite well
You talked about the pipe , i used the pipe which came with it now you say this is for P-60 not 80 and i use P-80 please let me know what is the different between them and what did you notice when you did that , however what i notice that the take off distanice was too short or maybe your model weight is liter than mine maybe , anyway i need to know the difference and how could i get one if i like to do so??
THanks
