Got a few questions and yes im a bit lazy with the search button. plus i dont like post 6 thread when i can get it all in one ![]() Comming form a back ground in rc racing touring cars and electric buggy the freshly built truck has a few things that are odd to me: -No droop? Is this normal? the springs are a bit frim for such a light truck, or should i say for the low amount of sprung weight, i think 80% of the truck is in the axels. Since it does not get jumped nor race through bumpy tracks am i just over analizing this set up? IS this the norm? Im wanting to seach out some softer springs at this point. -Tires got bounce. ![]() A combonation of the two things above make this truck bounce when dropped from even a short distance(something i would not accept with my race buggy or even my sedans) Should the trucks not squat when dropped? The thing seems so sprung... Ill test again after the venting -Motor, uh my tuned CO27 is lets just say a bit much! LOL even on 5 cells. I have my 65T on order so i grabbed my CRC 12volt motor from my comm lathe in the mean time, that slowed it down but almost too much, not sure what specs this motor is so ill wait for the 65t before i mess with gearing and such. -Batteries, i have lots of sub-c cells 3300s,3800s,4300s and a bunch of IB 1200 and 1400 2/3a cells. IS the norm to run a 5cell receiver pack and a main 6 cell pack? OR just go right with a 4200 sub c pack on the axels and skip the rx pack? I have enouhg 1400s that i though about going 6 on the axel for main power and 5cell on the front of the top deck to run the servo. Thoughts? Lipo is not really an option since i have so many retired race packs at my disposal and the 2/3a cells -servo, go my sedan servo in there hitec 925, a bit fast but about 120oz of torque seems to be working fine. What if i replace it should i consider a minimum torque rating for a truck of this size? -Body is in the paint shop..... hope to get it back soon thanks in advance... need to find some rocks now! |

its bouncy if dropped but the stock springs will end up feeling soft after you play with it.. its all up to you and how you like it... definately vent the rims... the 2/3 a cells would be the best, since they can be placed over the servo for more wieght up front..i'd go with 6 cells for the 65t.. your servo will work ,but 200oz or more is a common size for crawlers.. other than that just read read read...... |

Ok so i vented the tires. But the truck still bounces when dropped. Could others owners verify if yours also does this? ITs not major cuz its not for jumping, but i guess im not used to such stiff springs supporting such a light chassis, is the bounce normal? And the springs are simply there to control articulation? And there should be no droop or sag? One more thing my c-hubs came loose and not on the trees so i missed wich where supposed to be left or right. The instructions said to build 2 identical axels wich i did, that gave me a front cast with the normal swept back angle.(this is correct as all cars or trucks use positive caster up front) But the rear is swept forward(negative). IS that the way its supposed to be in the rear or should i flip them?? -still waiting for motor, CRC 12volt lathe motor is doing the work for now but its very very slow -945 gear set on order to swap out in my hitec 925 servo Here is the ride. Here is my ride, simple clean paint job, Last edited by TKG26; 10-02-2007 at 09:26 PM. Reason: more |

rear caster doesn't matter unless you have four wheel steering.. and i'll say it again.. its bouncy when dropped, but when crawling you really never jump... do you??........lol |

no i dont jump it, so bouncy is normal.Thats all im asking. If its normal its normal, its the only RC i have ever owned that bounced. WEll i think my first car back in 1988 bounced! LOL I come from racing background so i find it odd to see something bounce like this ![]() |

Good looking paint job. If you don't like the green on the links and beadlock rings, use Easy Off (yellow can) and it will eat the green right off. Then you will have regular old aluminum. Leave it be or polish them. ![]() |

thanks, i like the green so far, but they are scapping on the bottom so eventually the easy off will come out! ![]() |

A properly set up crawler shouldn't bounce. Make sure the vent holes are big enough to let the air out fast enough. I use 2 1/8" holes. If you have added weight to the wheels (front and about half that much in the rear) then cut the foams in either a star pattern or a center channel cut. If it still bounces it may be the tires. Mine used to bounce but after getting the weight right it doesn't bounce anymore, but I use Losi and Proline tires. I have not experimented much with my Axial tires. It is very common for crawlers to be set up with no droop in the shocks. Some people experiment with different amounts of droop but for starters just leave them fully extended. Once you get more experience and drive time then play with droop. RX packs all depend on your ESC. What ESC are you using? An ESC like a Rooster Crawler will not need an RX pack or a voltage regulator. I use a voltage regulator with my Mamba25 because I use a Hitec 5998TG or 5955 servo. The Hitec 645 has about the minimum amount of torque you want. Last edited by Grizzly4x4; 10-03-2007 at 03:55 PM. |
