After Stuart reported the problem we decided to use a different switch. Currently, a switch corresponding to engine requirements is installed as standard. However, on my gyroplane, I stayed with the old one to see if the problem would also occur in mine. It's working fine so far.

Stuart wrote to me in an email that after repairing the exhaust, his engine runs smoothly below 2000rpm. The exhaust damage was likely due to problems with starting a cold engine due to choke problems.

I believe that the damage to the bearings may be caused by the way the Nano is transported. I recommend carrying it as described in the user manual. I would also like to note that this problem does not occur in the factory Nano, which is often transported.

Maximum take-off weigh is 518lbs. Empty weight oscilates at 253lbs. So payload (fuel and pilot) is 265lbs. You have 15lbs for fuel then. In theory.
