what are you useing for your ct5's for fuel.... i started with 20% traxxas fuel. worked very well... runs great in my picco 21maxx engines and the 2.5 as well as the ct5. but i got a deal for some powermaster 15% nitro from my LSH for 11.00 a gal... the Picco wont barely run on it... could not get it to stay running... would idle for a few but dies quick.. i dont want to even put it in the ct5 at this point... im going to buy 2 gals fo traxxas 20% fuel tomorrow and see how the picco runs after i retune it again... i ended up taking 250 ml of the powermaster 15% and 250ml of Byron Original 30% and mixed them.. both have 18% lubes. i was able to keep the Picco running after going to the new blend. but i still couldnt get it rich enough, i almost had both needles out. still die at mid throat on the picco.....

at this point, i am planning on useing only 20% in the cars/trucks, i ll use the powermaster 15% for the plane engines from now on.
what is your take.
