OK, more questions for John ... so, in the beginning there were 4 rotary motors made by stacking 2 snowmobile engines together. There were some motor failures and replacements were worked up. Were the replacement motors made completely from new parts or were existing motors repaired?

In the end 4 very advanced dedicated 4 rotor motors were put into storage ... were these motors that had been raced or new unraced motors?


Did the dedicated 4 rotor motors weigh less than the doubled up snowmobile motors?
