NO CRYING ALLOWED

Just get that thing back out and do some more damn flips
Get us another new vid tommorow

I use this one and has always seemed pretty accurate.

Unless the fan is on all the time I wouldn't worry to much about the esc, the fan is doing it's job, just make sure the fan comes on at start up everytime so you know it's working. Also because your tires are slightly bigger and heavier I would have to recomend dropping a tooth or two on the pinion, that will definately help the esc, and may help the motor a bit too. I think the brushless MTs all come over geared out of the box, gearing for over 40 on 4s is a lot!

I did experience a hotter motor running those tires on my previous Flux build. They do weigh a lot more. They're around 320gm each, stock tires are about 250gm. So thats and extra 280gm of rotating mass all up or 28% more tire mass.

Unfortunately i didn't have a temp gun at the time so i can't quote temps. However i do know it wasn't so hot that i couldn't hold my finger on it and that was with 5mm chassis and LST shocks adding more weight.

So far, im not too impressed with the XL conversion all around from my few drives with the truck. I may end up going back to stock Flux size if my tweaks on the XL chassis don't improve it. I think actually prefferred and had more fun with the Flux when it was twitchy and unstable due to the insane amount of power on a standard MT chassis.

Well just got back having a BLAST with "Frostbyte II" without the XL conversion. I was amazed at the difference. With FB2 back in stock form, wheelies were now simply on demand as much as I wanted, so much so that I forgotten how easy it to flip it on its lid, the XL conversion definitely cuts down wheelies alot, under 4s power anyway. I now also had the ability to control my truck in the air alot quicker then with the XL conversion. I was now easily able to do backflips for all the kids in the park that were running from the birthday party and skate park to watch my truck in action. To bad I didn't have my camera to record my jumps, backflips and shit loads of crashes, but I was just too busy having fun with my truck at long last and watching little kids go "Whooooaaaaa!" as my truck did wheelies in the dirt, jumped around and did speed runs, not to mention my numerous crashes and bad landings which only resulted in breaking the front bumper support strut, thats it!

I also recieved my Duratrax temp gun this morning so I was checking the motor at random times. I never saw the temp go above 48c and the MMM fan was sometimes running, sometimes it wasn't. The XL conversion definitely puts more of a load on the motor on the stock 20/44 gearing.

That being said, i've got some major cleaning up to do as it rained last night so I got FB2 a wee bit dirty but I had a blast all the same. Now its just a matter of if I wanna jump up to 6s with the XL conversion kit or just leave it in stock chassis form and do a new body. Needless to say, alot more driving and having fun is needed!

I can't believe you don't have a tempgun yet. Measuring = knowing. I'm also using the Duratrax one and I feel it's pretty accurate.

I have been driving my Flux / Flux XL on 4S for over a year. Never had heating issues. Recently I purchased a set of HPI Terra Pins which are quite a bit bigger and heavier than the Mashers and BadLands which I usually run. I noticed immediately (I measure temps every minute when I change something on my car) that my set-up was running hotter onroad then normally offroad. So I dropped from a 20T to a 18T pinion and problem solved. I'm still running 18T, also with my other tires and can't really notice a lack of speed so far. Normally I'm at max 60c / 140F on both motor and ESC. When I'm solely jumping I'm at 45c / 120F.

I would just drop one or two teeth on the pinion and try again, AFTER you have your tempgun.

ps. My XL was lighter than the stock so that's not exactly even to your car which is probably a bit heavier than stock.

I have the Duratrax one and it works fine. But this looks pretty damn close. 60% off...

Up to 230*F Past that and your motor is cooked anyway....

With Stopwatch to time your runs. LOL

that is fair enough! you know what you like, and i know exactly what you mean! the flux is a lot more fun being a ballistic and hard to control sort of truck... keep us posted

I really don't like the XL conversion due to the fact that it makes it much harder to control the truck in the air and wheelies are hard to do and maintain. The wider wheel stance also makes crashes alot harder on the truck itself due to the increased leverage which resulted in me breaking the rear linkage today. And the truck doesn't recover as well from crashes and poor landings with the wider wheelbase, its less forgiving.

I basically miss the near out of control feeling the stock Flux has. I just got done taking off all the XL conversion parts tonight and im gonna go drive it tomorroo and see what I think

[thzero]

I would say that the arm could have broken in a X/Flux just as easily and really has little to do with the extended axles.

Go figure that wheelies are harder, you have a longer chassis which means that it is going to take more force to rotate the truck as the weight at the front has been moved further away from the pivot point. Pretty easy physics experiment to reproduce.

But you gotta do what you gotta do to have fun with it.

Btw is tomorroo related to a kangaroo?

Isnt that most of the reason people convert to XL is to help keep the front end down? I really dont think you can compain about not being able to wheelie or correct in-air antics untill you run at least 5s. The 4s you are running is barely enough on a standard flux, let alone an XL. Also if you are using punch control it greatly reduces the ability to correct in the air. Not sure if you are using punch control or not but its just an FYI

[Nard Cox]

I can still do standing backflips on 4S with my XL conversion, driving till topspeed on the rear wheels is also no problem. In the air I like it more than the normal Flux size, it's more stable. I hardly ever need to adjust the car while airborne and when I have to it's just a sqeeze away.

If you decide to go back to stock Flux length buy the TCS conversion, cheap and I've only read good things about it.

While doing the steering mod i did indeed shave that part off along with some other parts on the carrier. I have a lot of steering!
