Gving the norvel/AP 061 a rest for a while turning my attention for now to my Pulse XT40 I do have the OS46AX conversion as one choice and to refresh my memory put my tiger shark 56 ringed conversion on the bench again today 12x6 wood zinger davis abc
mix the engine may only have about 30 minutes total time and held a steady 9800 again started late it got dark the graupner 12x6
would have done better it always beats the zinger by at least 500 this plane might do better on a 13x5 when done and in the air
will play with 13x4 or 5 martin the TS is the same engine as a JEN56
