RE: Composite ARF Tucano Build
Hi guys,
My Tucano is finish. Colin gave me a hand today and we gave the new JetCat it's first run. With the Biela 24 x 12 3 bladed Turbo Prop I was getting only 5750 rpm even with 166300 rpm on the turbine. All the quoted prop rpm in earlier posts must be based on rpm in the air. It also seem to me that the Engle props are more efficient, but I suppose it will all prove itself in flight.
With lights, smoke installation and complete custom cockpit including panels and two full length pilots all up, the empty dry weight is 20.4kgs/ 44.9lbs. without any added weight it balanced exactly on the wing retaining bolt and I will move the C of G forward by 10 to 15mm for the first flight (this can be achieved by adding 8oz to the nose area).
Thanks for all the help, suggestions and observations from all of you.
Cheers,
JanR
