| I need help with my AX10 scorpion build
I am new to the RC Rock Crawling Industry, and I need a few pointers. First of all I just put in an order for a AX10, and I need to know what you all would suggest to complete the build. I bought what the website suggested. I just dont know what I really need. This is what I bought that was suggested. * Tower Hobbies 6-Cell 7.2V 1500mAh Stick Standard NiCd * Dura TraxStreak Forward/Brake Hi-Frequency ESC J * Futaba 2DR 2-Channel AM/2 S3003 Servos * Team Orion 27T Double Method Motor Thank you for the help. Oh yeah make sure you put things so I can undestand them, cause I am new to the whole thing. I have done some research though. |

the mamba 25 is a blushless only esc.Im pertty sure the 27t is a brushed motor if he wanted to have a drag brake with a brushed motor. he would need a mamba max.also I wouldnt use a 27t.I would at lest use a 35t lathe motor Quote:

umm... yeah i would get an esc with reverse, you have to have it. and a much higher wind motor unless you wanna jump it. and if i were getting that kit i would probably get some tires and wheels too. |

i would agree with those above me...also you might as well get a bigger battery too..like a 3000mah, just so you get longer run times plus its basically the same price...also ditch all of those suggested items...get a better battery, and higher turn motor, a better ecs.like a novak xrs..it works well, and yes get a traxxas TQ3...but what you bought will definutly work...just my $.02

IMHO,you'be be better off with..... a 6-7 cell 2/3a pack (perferably a pack built with Intellect Battery 1400 ) Esc,my choice would be a Mamba Max But a new Rooster or Tekin Rebel 2 would work allot better than the Dura Trax Streak or a Novak XRS. Radio,Theres some of the more popular crawler radio's allot of guys use here You'll eventually go to a 3 channle and set up dig in the rear anyway,might as well get a 3 channle radio to start Motor,like stated above,a lathe motor would be better. Better yet,a brushless set up would be nice as well. Theres some good options here.....Holmes Hobbies Motors | |

From what I've read so far, not that bad of an ESC... But for that kinda $$, you can get much better... The BEC on the Streak isn't the best, 5V isn't enuff for a servo as they like 6V, and to get full swing from a servo, you'd need to run an RX pack, 5 cell pack to the receiver, of sorts... The radio isn't that bad for a 2ch 2 stick... The servo's, however, will last about 10-15 mins at best in a crawler.. They have about 40 in/oz torque and rather thin plastic gears... I've smashed more than my share of 3003's just in a XX4 buggy in pavement... I agree with brushlessnut... A 35t lathe would be far better than a 27t... I ran 27's on my Clod and going to a 35t was night and day better... They stall far less and are more efficient, too... No probz, dude... I hope I was understandable to ya... Sometimes I forget that some of the terms and words we use aren't too common outside of crawling... Hope what I said there was some help, too... | ||

So if I go with the tq3 then I need diffrent batteries. What servos do I need and how many? will this one work.Hitec HS-645MG High-Torque 2BB Metal Gear Servo If I go with the Novak XRS Reversible Sport ESC I should be good with ESC right. And for motor I would be ok going with Integy Matrix Pro Lathe 45t single right. For battery I can use a 4500 nimh...does it matter which one. |

Stick pack? - hard to fit into any chassis (unless you just throw it across the top, I guess) Even a stock TLT hump pack is a better option Duratrax Streak?? - Even my Mtroniks RV15 is a better choice. How do you crawl with no reverse?? Futaba 2003's?? - they have like 30 oz. of torque, utterly insufficient. Go with some TowerPro 945's A 27t motor?? - are we building a rock racer or a crawler?? 27t motor will give you way too much wheelspeed and no usable torque - 55 or 65 turn lathe motors are cheap and effective. If you have the cash go brushless - a Mamba Maxx/Hyperion combo | |

If you want rear steer, you'll need 2 servos (and a 3 channel transmitter is highly recommended as well - full time AWS via a reversing y-harness is hard to deal with) The 4500 you see is more than likely mah (nimh is nickle metal hydride - the type of cell) this affects runtime and nothing more I'm pretty sure. You want 7.2 volt, and the higher mah you can afford the longer run times you'll get. | |

That list of stuff is allot more crawler freindly. Not my first choices but better than your first list. I'm not a big fan of the XRS. It's pretty weak. You'll HAVE to run a reciever pack or voltage regulator since the BEC isn't worth a nickle. No cooling fin,it'll get warmer easier if your set up isn't right on. It'll work,just not the best thing out there. Honestly,for a good crawler ESC,your gonna have to get closer to 1 bill The 45t motor will be more crawler freindly. A bit slow for my personal taste but I'm a sucker for wheelspeed Did you see the links I gave you in my other post? Besides the 1400 2/3a's,Holmes Hobbies has some good deals on good cells. John can build them to any configuration you need. For a smaller rig,the 2/3a's seem to be better cause they keep the weight down. The AX10 Scorpions factory battery placemewnt is a bit high to begin with. Some guys are getting an hour and longer even with the 2/3a 1400 packs. The big cells will work though,no doubt. What charger do you have? One thing I've learned with electric RC......Having a GOOD charger is worth it's weight in gold. Your cells will get a better charger,last longer and you'll get better run times. | |

My recommended setup would be For a decked out ring
and for a charger id recommend the duratrax Ice as it will last you a lifetime and charge just about any battery you ever buy. Dont skimp out on a charger because youll just end up spending meaningless money. Last edited by Krawler Freak; 06-17-2007 at 09:11 AM. |

for the motor it really depends on what you want if you want a dedicated crawler i would go with no less that 35t but for my scaler i have used the method 27t double good motor for the price and for me it didn't have enough wheelspeed. i either use a mag mayhem with 15\87 gearing or a titan 550 motor wich i believe is 23 turns with 18\87 gearing. and with moabs niether motor has ever stalled.
