Hi everyone, i just got this tmaxx 2.5 from a friend for free, and it needed a glow starter, so i bought one, but i was looking and wondering what this blue wire went to. Ive looked and not seen where it would plug in anywhere. Can someone please help me? Thanks

down inside the cooling head, there is a glow plug, just line the center of the tip of that blue wire up with the small tip on top of the glow plug and simply push down.

it is the source that lights your glow plug while starting it too to answer your question.

P.S. If you have big fingers and can''t really fit ur finger inside the cooling head, a pair of needle noses will work too, just make sure not to scratch up that wire to the point where bare wire is showing

that is the wire that feeds power to the glow plug. on the top of the glow plug there is a pin, and the spring on the end of that blue wire slides over that pin. its all part of the ez start, the ez start powers the electric motor to turn over the engine and also powers the ignition of the glow plug. make since?

Yeah Thanks a lot guys, i will try to fit it in later. If i have any more questions i will post it here. Thanks

Nice of him to give it to you, but its not the 2.5 its a 3.3 T-Maxx which is way better,well at least it looks like a 3.3 to me

slurp91193

a beter wayto tell is that it has got an optidrive or watever on it

Indeed that is most definately not a 2.5; but a 3.3; the way u can tell is the color of the cooling head. On the 2.5 its like a silver/gray color and on the 3.3 its anodized blue if im not mistaken.....

CarFreak92

you are all wrong

its is a t-maxx 2.5R as it has the low profile chevron tires and the trx 2.5r. this can be seen as there are no hex screws holding on the head protector.

so that is better than the t-maxx.

you might aswell get a 3.3 to finish it off.

matts6887

Oops!!......well then I did dun goof-ed!!!

iamnot

it is the 2.5r version of the engine for sure
they came with the blue anodized head
the 2.5 came with the silver
early in the 2.5r production there were some internal differences between the two engines
but later it was just the heads
the blue on was cnc''d and the silver was cast
supposedly the blue one cooled better

there are lots of ways to tell the chassis is not a 3.3
no opti-drive and black plastic for two

in any case
free is a good deal...

Yeah, well it was all clogged up so gas wasnt flowing into the carb. So i got that fixed and started it up and it ran great! But its weird because it stalls about every 2 and a half minutes. If you either pull the throttle to quickly or just in the random. I might have to tune it, but ive tried and it didnt fix it. Any ideas?

matts6887

Sounds just like a ordinary tuning issue with the needles. I would go back and re-set the needles to factory settings and try and re-tune it from there; which hopefully will possibly correct that issue.

iamnot

you may need to pull and completely clean the carb
may be some gunk still in the main needle or slidebar, etc

yeah i adjusted it a bit and it seems to be working great! Besides the occasional stalls but its really fun. Now i just need to get my rc10 gt working. That should be fun.

matts6887

Well as for the occasional stalling; that can happen to almost anyone with just about any nitro. But other than that, glad to hear from the sounds of it that u got it running pretty well. Have fun with it and of course BURN NITRO!!! [8D]

you may just need to bump your idle up a wee bit.
