|  help me climb greater angles So I built a board with sander paper on it for traction and mounted a angle finder on it. I fiddled with battery location, links, ect and then see if it will climb certain angles. Right now I can only climb 61* angles anything more and it tips over back wards. I get the passenger tire to come off the ground then over I go if I continue to move forwards. I tried even zap straps to hold suspension down so it wouldn't unload but still no more than 61*. What about link setups. What is the best way to get more traction to the front tires without more weight to the front end????? Do I need more rear pinion angle?? are my links where they should be??? already have 6oz per front tire and 4oz per rear. I have a four link rear with stock AX10 front supension. Have one spacer inside the shocks with one on the outside. Not too much flex. Shocks mounted upside down, links to the inside on axle and on skid plate, shock moved as far towards the tires as possible. had battery mounted on upper front link before but had no difference in climbing ability. Need some help. Want to climb steeper hills...... thanks in advance, Still learning by trail and error.......  Last edited by lil' lucifer; 12-09-2008 at 12:48 AM. |

| The main thing is to get that battery off. If you cant get a 3 cell lipo, get some 2/3 packs. As far as the stock chassis goes, I am not sure. I would look into upgrading.  I had the GC-2 myself and loved it. |

| In all honesty a dig would help you climb steeper angles by only driving the front wheels, and thereby stop the rear end from "driving under" the rig and causing it to flip. You could also mess around with your link placement in the rear to increase your rig's anti-squat. Here's a great thread on that whole subjet: Standard issue: Black/Green Bug Ax-10 And you should really, really buy either split pack alxe mount battery plates or a servo/battery axle mount to lower that front battery. You have the right idea putting it over the front axle, but it would be much improved with an actual axle mounted battery setup. If you don't want the investment of li=pos, go to www.cheapbatterypacks.com and custom build yourself a 6-8 cell slpit or brick pack using the elite 1500 maH 2/3c cells. |

However, i wouldn't throw away your sub-c pack just yet. If you have the know how, it is possible to make a split pack to sit beside your steering servo (a great benefit of the wider ax-10 axle). although its merely 1/2"-1" lower, its just enough to help (this method greatly helped mine). Shoot for setting the batteries on top of the axle tubes. Also, its pretty common to put the esc/rx on the rear axle. its quite easy, as it only requires a flat piece of aluminium. ps. I'm curious why you have your rear links mounted differently? (third pic) | |

| [quote=srfrkyle1234 ps. I'm curious why you have your rear links mounted differently? (third pic)[/quote] What attention to detail. By the looks of it I think it was to change the pinion angle for ground clearance. Unfortunately if you check out the link I posted for the "anti squat issues" you will find that that is the opposite of what he needs to do and is likely a major contributing factor in his rigs tendency to flip over. |

| the rear is to neutral. You need to lower the upper links at the chassis. I would put them back in the stock holes. Oh and get you lowere links between the mount tabs on the axle. Having them that far in isn't doing you any good. |

| 61 degrees is really good. Don't think you can get much better. The ramp obstacle at the indoor nationals Saturday was only 62 degrees and I heard only one shaft rig climbed it. With the big battery and the stock chassis, I think you have squeezed (squoze?) as much juice out of this orange as you're gonna get. |

| If you can climb 61deg. with the battery where it is, that is great. My Banana rig climbs 70deg with full droop revo shocks. I would say if you can get some saddle pack batteries or the axial servo/battery mount and go lipo it would help your climbing greatly. Also maybe some more weight in the front wheels. Each one of mine weighs 1 lb. and my rears are 12oz. each. |

| really I thought 61* was satisfactory?? I did not know it was good! I going to get some different lengh links tomorrow, along with battery mounts for axle along with new sattle batteries. Might but front four link too. Changing rear upper links and moving rear lower links back to stock location on axle. |

| Several things u can play with like tires and foams. If u can try running some preload on ur rear springs. Sounds like ur experiencing torque twist. Wat also helps to if u triangulate ur lower links on the chassis side. This should help u out somewat. Get ur weight in ur rig as low as possible. |

| A different Chassis with more Link mounts would help. Like some have said. get those 2/3a cell packs and mount them on the axle tubes. |

| If your climbing 61 deg. with a shafty, I wouldn't complain. Mine will climb 62 without a dig. 61/62 deg. is also just about the limit of traction. Be happy with 61, as most will not do that. As far as 70 deg., I won't believe that unless I personally witnessed it. |

| PS Holmes Hobbies is having a sale on their 2/3s split cell packs. That should gain you a degree or so. |

| Oops, sorry it's on our local 1:1 site. It talks about torque twist and links to this article on rcc http://www.rccrawler.com/forum/showt...t=torque+twist To be honest I think that thread should be sticked and the title changed. |

| Simple....ziptie your suspension down and climb vertical until traction is the limiting factor.  70 degree would be nothin. |
