You're right, the Losi's motor direction can only affect twisting in one direction. 1/8 scales don't rotate on the longitudinal axis because of motor rotation, they use the steering to accomplish that. Which is precisely what ThunderbirdJunkie did on his SC10 4x4.

Why do you get so worked up when somebody disagrees with you, and asks questions simply to gain further understanding?
It has more rotating mass along the longitudinal axis, but apart from the diffs being a tad heavier from the steel ring gear, there shouldn't be any significant extra rotating mass, especially that which would overcome the extra static weight on the chassis.

The dogbones, outdrives, diff internals, etc, are really not any beefier/heavier than the SC10 4x4's, so the weight of the SCTE is really kind of a non-issue...unless you think those ring gears are the ticket?

Dunno, guys, with stick packs or rear-mounted saddles ThunderbirdJunkie's SC10 4w was very VERY reactive in the air, to a fault. The SCTE actually feels calmer ITBJHO.

First of all thank you for chiming in!
Like Cam was saying im talking about spinning the motor backwards and using an idler gear mounted on the motor plate to keep everything moving the right way.
As you said right now the motor rotates like a RM3 setup but the SC10 is midmotor so the effect will not be the same. This is uncharted territory and it may not even work, could possibly even be worse but until someone at least tries we will not know! I am willing to put out the cash and time to find out, i have to figure something out and quick!

PSI did this on their mid motor conversion kits:

I raced and did r&d for them a while. The setup worked, but the idler gear wore out very quickly and bound up quite a bit.

Well, I dont know what to say, other than maybe the weight of the losi is overcomming the parachute affect of the body at high speeds, as opposed to the lighter sc10 4x4, giving it the the driver more ability to adjust the cars attitude mid air?

I only get worked up when you disagree and that stems from your comment weeks ago about me being non American. Up until today i NEVER responded to anything you post but for some reason you find EVERYTHING I say to be wrong like I am stupid. Maybe its the way you come across but questioning my patriotism is not good:flaming:
You seem to only post to start crap while i am ALWAYS posting about my experiences good and bad to help the community. Im telling what i saw and it wasnt just me or my setup. PM anyone that knows me and if nothing else they will tell you that i test ALOT, im at the track at least four times a week putting countless hours/laps on this truck. When you see EVERY truck with the same problem and different setups where does the finger need to point? on the last track my truck was perfect and on every other track around here it is competitive and super quick but this track exposed a weakness on this platform simple as that. You and WC are both part timers as far as i am concerned and obviously are not fast enough to realize there is a problem that needs to be addressed. My truck is fairly reactive in the air at lower speeds but at full speed there is no control or at least not enough to get you out of trouble.Here is a fact:
EVERY SINGLE SC10 WAS EXPOSED THIS WEEKEND, NONE COULD MAKE THE QUADS OR TRIPLES ONLY ONE SC10 WAS IN THE A MAIN.WE GOT OUR ASS HANDED TO US BY THE LOSI.
So anything you say to combat that is just silly, its a fact meaning that its not arguable. You cant disagree with a fact black is black, blue is blue. By arguing with me your just saying that i am lying for some reason. Instead of trying to prove me wrong why dont you spend that energy helping us racers?

I only attack when cornered, keep that in mind:tire:

I am assuming that you would want to see the condition being reported before believing it was true the other way around right? ;)



MantisWorx: Is there a vid out there showing the condition you are experiencing? i did some light searching and on some general SC10 4x4 jump vids, it seemed that at time they just couldn't control the vehicle in mid air on throttle or hard brake as you would expect on a different one. Wasn't consistent but did happen.

no video but i am going back to the track this week to try and redeem myself at least a little bit. But it was just as you said, it seems like if you go anywhere beyond lets say...22* you have no control and cant bring it down and the same goes for nose down. If you add 100% brake its manageable but of course driving around the rest of the track sucks, at least for the way i drive. Of course this depends on the lip and so forth but the tendencies are the same. It was never as noticeable as it was this weekend on this track.

Okay. If you can take a vid that would be great.

I notice something similar now I think about it on the tight indoor carpet track. Now of course my conditions are way different, but i didn't at least feel the same kind of throttle control to pull up the front end or bring it down as my buddies SCRT10. But, it didn't stick out much to me at the time as the vehicle was money every where else and I chalked it up to lack of time with the truck.

Hit me up when your gonna go bak to the track. Maybe tue, when i get out of calculus, i can drive over to mikes and we can take vids an do some setup testing?:)

You might try a set of Proline's bead lock wheels. Those things weigh a ton. :batman:

i am going tuesday to do some on road anyway but planned on leaving around 2 to come back but if you want to come out i will stay the whole day, its driving me crazy. Dont know if i can rig up a counter gear by then though...

Class starts at 1pm, but I have a test and should be done quickly. Ill bring my stuff in the car and head out asap! Gotta get this figured out!

After thinking about this for a few hours, here's my thought; this truck rotates FORWARD (with brake input) with much less input than rotating the nose UP (with throttle).

Marcus may be on to something...

i am not taking one side or another....but for the nose to be thrown down when applying the brake in air, the wheels must have been moving in the first place. if you come off a jump incorrectly, and you are too far nose down, no amount of throttle is going to bring the nose up. this is much more pronounced with the added weight of the exotek. i am still adjusting to this.

that being said... losi's are more reactive in the air. from what i have seen from capable drivers is that they can make jumps that a nitro 1/8 buggy cannot. the only thing you can do is focus on your line.

So with the heavy middle section it is making the truck harder to pivot in the air?
