The next point is, that there is a cooling problem under the cowling of a Mini500. But besides these eningeering failures, there are others, too. One is a lack in structural safety - or in other words a underdimensioned fuselage. An other one is the joint between the landing gear and the main fuselage. On the CH7 the bending forces of the landing gear are NOT transmitted into the main-fuselage.
Every owner wants to ignore it - because the amount of money needed is high.
Every one who takes a closer look will see that the best way will be to take all the parts of the powerplant out of the kit and buy the fuselage, powertransmission and exterior of a CH7. And then - do whatever is needed to achieve safety. I hope all of you will advance in solving the whole problem. I have always hesitated to write the below few paragraphs for a number of different reasons. Perhaps the reason is only because I am not and never have been much of a the mechanical type of guy.
