Ed and All,

I may be wrong but do not believe that the Engine Control System that Paul

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 examined the wreckage of Paul Conner's aircraft is now available at:

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