the first of the Rotax Max 125cc engines cracked into life today and spun the fan for the first time

early indications are that the concept works, the centrifugal clutch engages just above tickover and doesn't disengage until you reach tickover again, on a fast tickover the fan stayed fully engaged

a minor issue with the floor flexing under chain tension but nothing that can't be cured - we hope to be hovering under the power of both engines by the end of next week

the weight of the thing with only one engine in makes me think that with just a single 125 engine it will make a cracking Junior or novice craft - won't be difficult to find out

and it's relativley quiet with the exhausts in the plenum

i'll keep you posted on progress, thanks for the positive comments and pm's so far
