TT 39 with 30%

[jakesvdm]

I was just wondering if I could run my TT 39 Pro with stock TT muffler on 30% fuel ? I was told to buy the 15% fuel for it.

Also, could someone explain to me what 30% fuel is ? Is there any advantage in running 30% over 15% ? Thanks

Have you read the manual that comes with the engine? Normally they will tell you which fuel is recommended.

15% nitro fuel has 15% nitro, the 30% fuel has 30% nitro.
The 30% will give you a little bit more power, however the engine will run a little warmer with your current (if the engine is tuned for flight) settings. Richen up a few clicks, i personally love Coolpower 30% High Performance Heli. kinda pricey but worth it.
Concult your engine manual FIRST, it should have a recommendation as to what percentage fuel to use.:thumbup:

The engine manual says it could run on 5% - 30% nitro. So if I use 30% nitro I will gain a little power, but I might have to richen it up a bit, thus loosing a little power. Will the over all effect be a gain in power then ? About how much ? I mean, will I see the difference i.e. in climb outs ?

you'll get a little bit more power, if your a Noob then you may not notice it, you will have a little bit more power all around. As for how much gain in power, anywhere between a little a holy smokes! some engine really wake up at 30% others just idle and transition better.
