So dad put his foot down... it is his truck. He basically said traxxas had 3 shots with 3 different engines and they all did the exact same thing. He said it's up to me but he'd prefer trying something else at this point. I don't know. Will report back as time goes on.
I still haven't pulled the trigger. I called my friend who is running the dynamite to ask again how he liked it. He said the main thing he preferred abut it is that the carb seems to be better than the composite unit otherwise its about the same as his old 3.3 just holds a tune better in that...
Haven't committed yet. The dynamite is tempting because I can have it tomorrow (i have the itch to run something lol) but it should have a 3.3 back in it. It's just that thing was a pain in the ass from day 1. I'd hope the new one is better but I don't know. I'll make the final decision in the...
So I retested it. Crank seals leak depending on the rotation of the crank. Obviously not worth repairing in my opinion so a new one is on the way. Bet those bit the bed shortly into usage.
Rod didn't break, Rod went straight through the top of the piston lol. The failure on that to me was too much pinch but what was left of the piston seemed about right in the bore. I wish I still had that to take a picture of, Only time I ever saw anything like that was when a friend hydrolocked...
It had a 3.3, was a bit uncontrollable with it even with the long chassis... then it launched a rod. The 2.5R was perfect for one tank lol. A friend told me to grab a dynamite .19... I'm tempted to give up on this mill regardless at this point. Maybe it'll eventually make it's way into the nitro...
Pulled it apart, pinch is good, nothing odd with bearings or metal bits... just not seeing much. There is a bit of varnish on the rod but nothing to write home about.
Flywheel is dry as is the case and clutchbell. Chassis is damp but I spilled fuel while filling... it doesn't have anything flung out so to speak. 3232x plug.
I pulled the cooling head off... there appears to be a perfect minus in the top of the piston and there doesn't seem to be much pinch. I...
They're melted like a lean out though, and they fail the same way too... Wide open right past then as I brake and make the u-turn, just before I get on it again boom, nothing. I wouldn't normally be picky about it but the fact it is so consistent when it happens almost makes me think you may be...
Soaked it in degreaser (the pipe) cleaned as much as I could with brushes then blew air through it. Readjusted all the fueling until it seemed good, light smoke at idle, nice trail running it flat out. I was ecstatic. It went through a whole freaking tank without touching the starter other than...
Let me preface this with it took all of my being not to chuck this thing clear across the effing yard.
Anyway, I pulled apart the carb, cleaned the passages, and put on the o-ring conditioner. Topped off the tank and ran it on the base settings. Ran mint. As the tank got to half I fattened it...
