The Topaz is finised

Post by Robcrad »

Hi all,
Finally finished the Topaz from the Chris williams plan in the Scale soaring digest, It is a bit of a first for me, first scale glider built from plan only, I normally build kits.
Fitted with Frsky redundancy hub which has 2 independent receivers and 2 batteries, Kingmax servos.
Just need to set up the radio, which leads me neatly into a question, what are the throws for the ailerons and elevator?
Need some nice weather now to complete the maiden.

Rob

Hi Chris,
Thanks for the info, I had a quick look on the plans and couldn't find they throws on them.

regards
Rob
