Thumbs up How heavy is heavy??

Im totally newbie with crawling. My pathfinder is only 1 week old.

I noticed with HB rover tires with stock inserts but with some weight(no idea how many in grams i put) it can climb just a little bit on a slightly above 50 deg path...

but when i just touch it on the front axle with little bit of pressure, it can climb right till the end... does this indicate i need to add more front weight???

wish i can take picture to show what i mean.. pls give advise. thanks in advance

Your COG is to high. You can try a couple of different things.

1. Run Shorter Shocks
2. Use the Stock shocks and mount them on the axle instead of the links.

But your best bet is to get a new chassis from just about anyone of the Vendors on here.

Once you do that. Work on weight placement.

Yep.. i realized the original stock form of the Pathfinder is way high up there. ok checked that.

I think i wanna try the no.2 option 1st before goin to the last suggestion ;) I just got this new crawler n getting new one is asking myself and the internal finance minister too much already, if u know what i mean

Thanks run2jeepn. Appreciate it very much. Finally able to chat with you here. If you have not seen my blog yet at JonehRC.com, I just wanna let you see my post on your Beetle Pimp Cane crawler. Posted long time ago Feb 8 2007!!!!

Here's the link: Rock Crawling. Non Nitro Style!

I thought the same thing with my AX10 scaler...so I strapped another battery to the front axle and gave it a run...helped a bit, but not lots...try it out, yours might work.

I think that since your/we're pushing down on the axle, we are varing the weight needed to help climb the obstical with out really knowing that we are changing the weight...that's why I put a battery on mine..its more constant weight, just to test. What I just thought of is put a pill bottle on your axles somewhere and fill it with bb's, then climb it..adjust your weight and then test it again. once you get to a weight that suits you, weight the pill bottle and add that amount to the wheels (divided of course).

just a thought...

on your COG, couldn't you just adjust the shocks where they are attached to your links??? that should lower your whole rig.

WOW. that is my friend, a very very good idea on getting the right weight. I will try this also. awesome idea.

that's what i wanted to do actually. the kit has 3 holes to adjust the shock location. Mine (not as the picture above) already on the far end, last hole. if only i can find ways, correct and safe way to drill hole onto the tiny link, i will add more holes for adjustment.

thanks. everyone. thanks a lot. i will try all your suggestion and be back on this thread with pictures.

I'm back here. I so love this forum... will definitely contribute something here... i heard i need paypal moolah to get the star(s) ;)

Anyway, here's my update.. the pictures i mean

Below during my crawler build.. so i end up just a cameraman :(



Below at peace.. watching the cloud right on the top


below is from our last meeting.. with the scalers. They so so.. cute



Below is during our 1st competition. Tackling the tighter corner.. meant for the 2.2 rig... man what a disadvantage!



Sorry for the big picture... hope i didn't create any mistake here. the HB rovers are totally awesome. I just wish i have a shorter axle width... :(

I am new to all of this as well and dont have all (or any, LOL) of the answers, but I just read on another thread that another member had added to much weight to his front wheels and was burning up his drive gears. Apparently the gears could not handle the strain put on them from the extra weight. I know a lot of these guys add it to the wheels and I will do the same, but be careful you dont add too much. Just thought I would pass this on. Good luck and listen to these guys they are a great wealth of information.

same like our computer chips went across and beyond

Well, im not sure about the weight, i not yet have a scale to weigh it but I know front is more like 80:20 ratio the rear in term of weight distribution. My crawler climb better now. No problem in term of going down the hill.. with the drag brake.. its a matter of throttle control.

Yes, i found out about that too. If i see our rock crawling site is with lesser height, small hill kind of obstacle, my crawler climb or crawl better with lesser weight than before.

Yes of course i will listen, learn and hope can put into practical. Most crawler people here are nice people that willing to share. I just love it. i especially like to "hang out" at the MOA thread.

Oh ya, with the thread question answered.. the how heavy is heavy? .. i have another question regarding the motor wiring. is parallel wiring a must or just stick with the default 2 sets of wire to each motor.. series??

or shud i open another thread just on this question... thanks everyone. thanks for all the help so far

Yes it would be.
Tested mine with lower COG and it was better.
Better tyres and servo and it rocks.

There's quite some room for adjustment on this rig.

Will post pics this weekend after some tests.
