To be quite honest I believe there is still just that slight amount of detectable tail wag but again, I think it is more a factor (potentially) of my needle settings or the preciseness of my mechanical set up, i.e. main & tail blade balance, etc.
Personally, and again I am by no means an expert on gassers and the only thing I can compare it to are my 50 & 90 nitros, I think I am expecting a level of precision that is just not achievable on a gasser. I saw Raja's machine fly at IRCHA and my personal opinion is that if he can set mine up (which he did) to fly as close to the way his does, I am more than 100% satisfied. Raja has sent me a few PMs regarding this thread since his level of interest in the Spartan is high as well.
I still intend to swap out the 9256 with a BLS251 as soon as it arrives. This will probably be the real test. In addition, I will have my friend Parker put it through its paces in FAI style.
Thanks again for the interst and responses guys.
