Hi Bob;
Another question(s) re the ByroJet/Rossi powered RE: Several of the sites here at rcuniverse have folks recommending that the ByroJet version include a large belly cheater hole; others are recommending no cheater hole for the RE (?). Is the latter possible without significant degradation in thrust? If no cheater hole, does it need special intake ducting or enlarged intakes? Finally, apparently you also recommended a "lay over " engine arrangement - any particular side (left or right?) Thanks! AL
