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.

Timmah - We recommend using Byrons Original Racing fuels at 20% for our vehicles. If you plan on going racing, you can bump up to the Byrons 30% but keep in mind that you will put more wear on your engine from higher nitro content and less % of oil. Your engine will however make more horse power.

Thanx for the quick response... i dont plan on Track raceing persay, but was wondering and never really seen anything stateing what is recommened.. i figured 20% maybe 25 would be fine...

Timmah - I don't know about mixing two different types of fuels together either. We recommend that you start out with a fresh bottle of fuel and go from there.

Have fun!

I started out using Trinity Platinum 20%, ran great. For some reason I switched to Trinity Monster 20%, and my Nemesis would not stay running at all. I believe I got some old fuel in the Monster HP. Fresh fuel seems to be the best recommendation.

Im running Odonnell 20% fuel and it seems to be working fine for my Force.28 engine .Its a new engine with only about a hald gallon through it so far but the jammin idles fine and has always started right up for me .
