Many thanks for your reply Dick. The reasonI asked about the angle of the anhedral tail is from the build artiicle for the Tiporare, where the designer (Dick Hanson) recommended reducing the angle on his design if Not using a tuned pipe. as i will be using a " mini pipe" I wondered if a similar reduction is necessary.
At the present moment i have just placed an order with " Eureka" for their short kit with foam core wings & tail..................which should arrive in the Uk in about 4 weeks.
I will probably install E-Flite electric retracts and use seperate Futaba 3152 digital servos for the ailerons, rather than torque rods, as well as 2 seperate 3152's for each elevator half.
I will keep yu posted on progress.
