For the first time It did, but this is because I went crazy and tried to climb impossible negative incline But it handles everything great and front climbs up straight 90 degree angle with no problems

I'm not sure but I think the greater the angle the less side to side movement , because I can still move the axle slightly side to side , but it's too little to make a difference in a lego model. Another thing I wanted to point out is that the point where the ball joint is attached has to be in line with the middle of the U-joints to prevent the axle from the driveshaft to pop out. the way I built it one side isn't in line so If the chassis was higher in the middle the axles would pop out. But I have it limited to the maximum clearance befrore that can happen, you can research it if you want further understanding, because this stuff just comes to me naturally :) A#1: It's stiff enough, yes. This piece with the ball joint on the servo sometimes slips out after a long time of constant steering but I'ts ok. It needs some improvement... for equal steering I'd need a 9L link with the servo a bit to the left or right from the middle of the axle. But as it is it turns(when on a flat surface) a bit less in this direction: Regarding a video...sorry but no promises, I'd like to though because this performs very well, maybe could do windows media player video, but the main reason...I'm not sure if I have a proper camera. Maybe could make youtube account but need permission, as I am (sorry please dont ban me, I behave!) a bit underage.

@Dluders thank you, will probably get those in coming months. Great to see so much feedback! It's like brainfood for more ideas Be sure to visit my brickshelf! link is below.

Sorry, can't make video, but here's a tip for four link setup, It's all about GEOMETRY. You have to triangulate the links. To simplify this phrase, lets say two links are set next to eachother on a table. they are parallel to eachother at a distance of 5 studs. first, move one end of both links 2 studs further apart. so at one end the links are 5 studs apart and the other ends are 7 studs apart. Now to equalize the forces to keep the axle the links are connected to from moving side to side is to add two links on top of the previous two at opposite angles. this is too confusing. Here's an example:

LOL, just noticed that it looks like that, my bad! Actually it's attached to this piece which can move freely on the axle. It actually has more flex than 8110 or 9398 ever will . For example:

Yes, the only thing separating this from rc performance is a superfast motor with good torque-like buggy motor but with more torque. But I doubt plastic parts would handle it, so thats the limit, but then thats the fun, pushing the limits. It's not metal rc, it is just our wonderful Lego.

no the bley gear with pin hole opposite to the tan one with axle hole balance eachother out so no slippage, and yes I'll try to place battery box elsewhere. Axles where inspired by your raptor, yes, but steering of course and top link mounts are different. And axles have much more flex than the Raptor. Glad you like it!

cool truck, I've also demonstrated a simple lego rc moc, and my class thought it was cool

I am showcasing my all new CrAwLeR with four link suspension, lightweight chassis and most importantly, new axles where the 9398's servo motor directly steers with no need for those pesky racks which take up space. I take this as the first model using the servo motor on the axle, but excuse me if someone beat me to it. Theres lots of room to improve because I built this in only a day, but this provides a simple platform for people to change. No room for two L-Motors so I used xl mounted vertically for the least amount of parts and weight. It's AMAZING! Only problem was the fact it's so light that these stupid lego tires(no offense, they're ok for models but not crawling) have little grip. In time I will buy rc tires similar in size to unimog tires to keep wieght down but same scale, and more grip Here's pics:

Did you use the regulator part I told you about in your other topic, since I see the custom batteries.

I scrapped the idea of making 9398 four link with original body/chassis and currently installing xl motor in middle of whole new very lightweight chassis, but still have a 9398 with all its guts ripped out. Axles are finished and installed, geometry all figured out, cant wait to see how the servo directly on axle with no steering rack performs. Will post pics on brickshelf and here when finished. BTW coupling two L motors in a tight space in middle of chassis was hard, so I'm just going with xl. Unless someone has any bright ideas...

I posted pictures of my WIP drift car, and only got two replies, the fact that I got little attention doesnt bother me, because I've built two MOCs since then. Just because you're not a star doesn't mean you should quit. Who knows, the next one might be all that anyone's talking about

I am currently modding crawler to 4 link and servo on axle, may I post pics here when I load them up on my computer? It's a WIP.

Yes, we tried without regulator, and burned out our receiver . We fixed it and now use regulator. google the part# '78L09' Good luck!

Did you damage the motors with that big water splash?

I've had this custom rechargable battery that my father made for a while now! It uses 3 very powerful lithium batteries which create 10-11V, and it's connected to the pf receiver so theres a regulator on it so it doesnt burn the receiver. sadly no case so it's a bit tough finding a place to put it on my models, especially because of the triangular shape. I charge it by putting on alligator clips onto the contacts, hooked up to a power supply box. It lasts very long. A bit dangerous but saves lots of batteries I have two and nearly lost one when one of my rc cars lost signal and plunged into my pool, but I grabbed it so only the front half and motors got wet. everything was ok.

These L-motors are VERY useful I am currently remaking miron89's mini trial truck with the new motor and my custom battery. If it works will post pics in my MOC thread. Wish me luck!

Yeah you're right but It's better than what happened with the other tires, they had so little grip they couldnt even get the rear axle up onto the box! It was easy with the pp's though

Fixed, better now? ps will post 9398 pics soon

I finished building I modded as I was building. I replaced the two 16t gears with 12t/20t and diff with knob wheels and 8t/24t in portal hubs. I also used pp tires(makes it look much better and more grip) and i removed those bley guards at the front of the axle because it gives better ground clearance and they're not really needed. It's slow but it's got plenty of torque. It was bigger than I expected Now it performs great, struggles on a step-up obstacle where rear axle does all the work, my knob wheels dont squeak though like sariels but it seems to have plenty of torque. theres one problem...does anyone's servo struggle to steer all the way??? Maybe this is because I removed diff and put on pp's??I'm probably just exaggerating though...Will prob post pics too.

I guess it is a bit early but interesting to hear other people's ideas for models, I've been wanting this dodge dart rallycross car with all the functions, and possibly rc: maybe someone will make a 'flagship ideas' topic

I used to keep this hobby to my family and nobody else, only in past year have I shared it with friends. During computer class my friends saw me looking up various models and sets and were skeptical of my hobby because they thought it was 'childish' and probably thought of duplo...Then I showed them Technic-my models and others' famous creations and they suddenly went from "you play with legos " to "You can do that with legos?" and have respected my hobby since

so like this?

Yes I hope this isnt true I only have a few grey parts and hate when they mix with bley which looks better IMO, as for the set rumors-new tires seem nice(a lot of talk for customs lately) although it's a bike tire, and f1 sounds sweet, and supercar would be perfect flagship.

Sorry I'm away from home at another computer so I didnt have access to my photo album file, but I will be sure to do it when I get home
