mammoth gas question

[EMPERORLAY]

I haven't driven my xtm Mammoth in a while but I decided am going to take it out today but I don't remember what % nitro it takes. Is it 20%?? It has the 24.7 engine in it.:juggle:

20% is good. I use Trinity Monster Brew.

Make sure the fuel is fresh. Old or bad fuel can give you headaches in tuning.

Since you are unsure, run a couple of break-in tanks through to get the mill used to whatever fuel you are now using. Don't just slap the fuel in and go balls out. You could cause damage to the mill if the the nitro percentage you are now using isn't what the mill was originally broke-in on.

I just bought some new 20% xtm nitro. I also haven't driven this thing in like 6 months so we'll see how it goes. Just got to let this glow plug charge:moped:

I also bought a new glow starter and it's got a green and red charge level on the top of it. How long does it usually take to charge these thing's. It's been cgarging for about and hour and a half and it still hasn't moved out of the red area:depress:
