Very glad you got out OK that is the most important thing - never mind the machine. The statistics do not stack up well in your favour if it goes pear shaped at over 40ft in a Robbo - so well done
, I doubt many of us could have done any better.
I know it is impossible to pin the cause down without a proper investigation but do you think it could have been carb icing? What were the ambient conditions?
I only ask as I have experienced what I believe to have been carb icing in an R22 I used to own with full carb heat applied.
