had supported staged (four injectors) injection.......Again not
certain but I think
his ECS was a "Motec".........

John, I believe the TWM throttle body that
Paul got from Atkins which has injector positions comes with only two
injector positions. This throttle body was available from the
distributor (TWM) in either 2 or 4 injector model. I know from
personal experience that using the 4 injector TW (I had one initially
installed) on the 13B made a more difficult installation - because the
two injectors on the "inside" required you to position the TB a fair
distance from the engine block. So to avoid a lot of manifold work
(extending the TB further away from the block to give room for the two
inside injectors), the TB with only the two injector positions on the
outside were most favored for the aircraft installation. I believe
that was the only model sold by Atkins. I know of one other who also
flew with only two injectors, but there may be more.
Reduce fuel flow whether due to fuel
selector position or defective injector or combination during take
off would certainly be critical. As pointed out, when you lose one
rotor you lose more than 50% of your HP due to 1. Less rpm with only
one rotor ,2. drag of non-power producing rotor.

The analysis of the 4 canardians who

Does anyone know if and why Paul's engine was
configured with one injector per rotor?
