So i have a ofna and i just put a new hyper 21 engine in it. i broke it in properly and used traxxas 20% ( the blue stuff). now im home in germany and they dont have the blue stuff at all NONE so i used jets 20% ( dont ask about the jets there is not even a web site for it ) but its not blue would that make a difference? the fuel feels kinda cheap like no lubercants in it at allso i tried frieing it up and it truned over and then died so i tried again and same thing. now i was in california when i broke it in and now i live near frankfurt should i do anything differnt please some one help!!!

You will need to re-tune it. You would have to do this because of either the new fuel or the change in environmental conditions.
If that fuel really has no lubricant in it you should change ASAP.

i mean it has some but like the traxxas stuff make your hands oily and this one doesnt im shure it dones but not as well. and re- tune? go back to factory setting?

Yes, go back to factory setting and re-tune. Look on the label of your new fuel to find a lubrication percentage. If its higher than 10-15% it should be okay. As for the color of the gas, dont worry about that. Most fuel manufacturors add dye to the fuel for color.

Be careful about that fuel and check what it actually is before runing it.
You have no idea what it is or what it is for!!??

Some more good advice here.

I have never really like the Traxxas stuff.. I found it made my engine run hot, so you might be able to lean it out a little more with a different fuel.

huum thanks all for the good advice!

Traxxas fuel [:'(] way to much oil content. You do not want a fuel with any more then 12% oil.

yeah i agree it has way to much oil i havent had a chance to fire it up yet but as soon as i get on im firing it up lol!!
