RE: PT 40 take-off roll
G'day
I used to live in Sydney until 1987 and I flew control line at KMFC at St.Ives showground. The grass there was always great. When I moved to Orange the grass there was good too and always mowed but then I moved to Cowra and the field was OK but could get dusty and here in Dubbo it is usually pretty brown. At the moment it is not too bad.
The PT-40 was my second plane. I built it for my son and it worked well as a trainer but once he could fly it got bored with it so I inherited it for a while until I pranged it. Since then I have discovered the Sig Kadet Senior. A very similar plane in some ways but the kit version has no ailerons and as a result, lots of dihedral and lots of stability. I have just built another one to test a Saito 90 R3 radial in but I am currently building a modified wing with ailerons the same as the ARF version. I will not, however, reduce the dihedral at this time so it should fly very like a PT-40 with the high dihedral option. We shall see.
Cheers
Mike in Dubbo
PS, sounds like you have been to the zoo here.
