thanks dave. after being mad for a while i figured that "hey i should go back to factory settings and go from there. truck is running stronger than ever. its a good thing i got a few spare plugs today

ok im still having the same problems just not as bad. i ruled out the lsn cause i did the pinch test and it dies out around 2-3 seconds. so could it be my idle? if so what should i do. i kno there is a certain mm that it has to be but i cant realli eyeball millimeters and i cant measure it with anything. any help will be appreciated.

Sounds to me like the truck is too lean. This is what I would do: Richen the HSN until the truck is noticably slow (really slow) then gradually lean the HSN from there in 1hr increments until your power comes back.
If it's lean..... richen it
If it's rich....lean it!
That's what I do to make it run good.

well its running much better than before. i did richen it a little. i messed with the idle. it only died once after all of this.

I will get pics up of my progress tomorrow... I have some silicone drying. I did the single servo conversion, got the teckno throttle servo mount, and shaved the reciever box... a lot. I took off the roll hoop and cut off the front 1/3 of my Ti skid. I moved some crap around and it looks a lot lighter and cleaner than before. (My wing is a tad crooked but for a total of $18 I am very happy....)

since ive been hearing alot about the os 18tm and there short motor life would it be better to buy a new p/s for the trx 2.5r and get it modded or get it modded right now (aprox. 4 gals on it.)

FreeRideFrosty · (#283 (**permalink**))

Honestly I would do the motor swap or buy one of e-bay so that you have a brand new one to get modded. Then just save yours as a backup. It would be just a tad more expensive...

destroy_my_revo_15 · (#284 (**permalink**))

so if i do get the p/s should i get a crank too?

FreeRideFrosty · (#285 (**permalink**))

That I don't know... but wouldn't that all be close to the price of the motor swap or a new one on the bay??

FreeRideFrosty · (#286 (**permalink**))

Better yet get the XTM .18 off of ebay for $60...

destroy_my_revo_15 · (#287 (**permalink**))

umm if you get a super steal you can find the p/s for $50 shipped and idk how much the crank costs definately less than the trade in or a new one on ebay tho

I used run the os .18's and there fantastic motors while they last. But because you can only get about 3 gallons im going back to the 2.5r. That motor rips as well and is an awesome motor for just being a .15

snakebite46 · (#289 (**permalink**))

That XTM .18 is a nice cheap upgrade for the Revo. Jesse Wolkenheim was running it saturday and the thing rips. He told me that it had a good power band. Little weak on the low but nice top end. Can't beat it for 60 bones.

Ive had great luck with Xtm engines also.
