Hi Mackey1;

I have one of the orginal Hangar 9 1/4 scale T'craft that may be close to your Nosen Citabria. I'll look for the instuction manual re the throws.
I know my T'craft needed very little for flight.
2" will be fine for taxiing on the ground. I mixed "expo" on the radio to compensate while in flight.

Another option may be to join in on one of the recent Hangar 9 T'craft threads and enquire to what the instruction manual indicates if I can't find mine.

Regards
