Thank you Marcel for your prompt reply.....Point 1, I was suggesting that one of the existing starting fixtures ,be moved to the flight line for starting/ restarting, so that the pilot is standing not kneeling and that the model is restrained. As for carrying the model while running, as we age ones balance is questionable, particularly if the ground is not level {me for one} and as the bulk of our members are seniors , I believe that the point is valid one. Correct tuning would be done there and then and the start fixture would retain the exhaust residue, so that it could be cleaned up easily. Waiting time should not be an issue if the model is reliable, if not, it would be sorted out in the pit area.
Point 2. Many smaller engines have a plain bearing crankshaft (ie; non ball raced] sometimes with excessive end float. With the use of electric starters the crank can move backwards allowing the big end journal to scuff the end cover, creating an alloy sludge. Not good.
Thank you for quoting the relevant code numbers....it allows the reader to make his own judgement on a given subject. Brian C
