1/2 throttle load up
Just got my revo 3.3, love it. have about 8 tanks through it and I feel like the low and high are adjusted well. But I have a problem at about 1/2 throttle, if I run the truck at half throttle for 5 or more seconds it starts to bog down, I then give it a blip of full and a puff of blue smoke comes out and goes back to running fine again. I've searched and found that it may be lean, but that doesn't sound right....could someone clarify?
Oh, I called traxxas because I the truck wouldn't move unless I was at half throttle or more. The guy at traxxas said it was fine to run the 3.3 at 1/2 or more the first tank because sometimes they just won't move. When I went to adjust the low speed on tank 6 I noticed that it was 3.5 out instead of the 1.5-1.75, it was flush with the outside part of the metal, not the inside where it should have been. After I got that back right it ran and idled great....oh well.
Thanks,

RE: 1/2 throttle load up
I seem to have this problem with my Revo near the end of my tanks. It seems like when I get to just around a quarter of a tank left it seems to bog a little. I usually solve this by backing off the trottle just a hair. Then again I am running an os .21tm.

RE: 1/2 throttle load up
lean out your HSN just a little bit, maybe even back your LSN some too, my 3.3 T-Maxx does the same thing but I like to run mine rich. have you done a pinch test when you shut the motor off?

RE: 1/2 throttle load up
These little motors just really arent made to run 1/2 throttle. They do it fine, but they will sort of load up. Most of my engines do that if i run them 1/2 throttle or so. They will run fine, but then it takes a good full throttle run to clean them out. It could need to be leaned some, but I think its just the nature of the beast.

RE: 1/2 throttle load up
This is one of my very old threads from my troublesome 3.3 days, thanks for dragging up a bad memory for me Clove, and for checking out my post history
. That was at the end of the line for me, I threw in the towell and let my revo sit for over a year as I got tired of trying to tune that sucker.
I tried to sell it on Craigslist last month for 250 bucks, which I thought was fair, but everyone wanted it for 100 bucks and I wasn't selling it for that.
So, I decided to get a new OS21tm instead(which has a 3 needle carb I believe), hoping for a better time. We'll see what happens. There's my story. Giving the hobby a second chance, while trying to not go electric.
