Hi guys,
Thanks for your responses,
Since posting this i have flown my apprentice a few more times and adopted a quick takeoff technique that has reduced the problems on the ground,
As the motor is set with lots of right and down thrust I have found take offs are best at full power, it just leaps into the air,
I was originally trying to do long gradual graceful takeoffs like real life and ending up in trouble with the grass,

I have also since put larger wheels on it and also shifted the COG more forward than the book says and for a beginner it is better to fly,
I had a lot of trouble getting it back on the ground before i did this,
It has been a good trainer,
The decals have long peeled off so my son and I are going to paint it with acrylic paint in cream and dark red with window blackouts just to make it look better,
Its not real pretty as a total whit foam model,

Have any of you had trouble with the decals peeling off,
Mine is kept in my garage which is about 48 degrees C at the moment as we are getting our usual heatwave,

Cheers,Paul
