"Most" RC trucks and such usually run in "normal" direction. The Mamba comes preset to direction: "normal". What are you putting it in? Also remember as a temporary fix you can reverse the throttle channel in your transmitter. The only truck/crawler that I currently own that runs a reverse direction motor is an Axial Capra. |

Re: Have tech questions? Will answer. Your welcome, It is best to do it in the ESC, but it wont ruin anything to temporarily reverse the throttle. Just change the ESC when you get the dongle. You will have better throttle resolution with it reversed in the ESC. |
Re: Have tech questions? Will answer. Can anyone please tell me what is the most expensive RC car in the world, and how fast is RC rock crawler. |
Re: Have tech questions? Will answer. Quote:
Probably something 1/5 scale. Probably $5k USD? Depends if you're custom built or off the shelf. Rock crawlers are slow because they're supposed to be. Some might have a top speed of 2-3km/h and some might go 20-25km/h You're asking questions that there isn't really a 'perfect' answer for. |

Re: Have tech questions? Will answer. Question with charging FlyskyGT5 Lipo battery. I have labeled 2s 1500mah generic battery for my Tx. I charge it at 1.5v 1500cap with a typical four button charger. When it is finished cells are at 4.2 and balanced but the charger says it is only putting 549mah each time I charge it. Is this all it will take? Is this battery mislabeled/sold as 1500mah? |
Re: Have tech questions? Will answer. Hey John, Just curious, given the increasing popularity in no prep RC drag racing, have you given any thought to making a drag race brushless motor? |

His Puller Pro R 540-L V2 is available in a new 6000kv version... PULLER PRO R 540-L V2 RACE MOTOR 6000KV: https://holmeshobbies.com/motors/bru...or-6000kv.html and I quote: "When you want efficient and controllable power , the Puller Pro delivers the excessive force you desire! The Puller Pro R 540-L is a rock race honed variation with higher quality materials for less heat, more torque, and less brake fade. It retains industry leading low speed control and throttle feel, giving you an edge whether in the rocks or pulling a run on the track. The 6000kv is borne from our 3s lipo U4RC race research and tuned up faster for 2s lipo sled, drag, and general overpowered mayhem!" and: "Notes: Designed for dominating 1/10th scale U4, rock racing, endurance, drag race, sled pulling, and general obscene power on 2s lipo. Also makes 4x4 stampedes an airplane." It's a 550 can size and has a 60,000 rpm limit. I have the v1 4100kv version, still waiting for me to complete the assembly of my 2nd Bomber-based rig to install it in. I shudder to think how much power it will have on 3S... "thumbsup" |
Drag Brake 7.4lb Capra with 4ws and SuperShafty Axles Crawlmaster 16t Pro Mamba X 3s 50C 9T Pinion Watched your video on setup. Current Settings Brake Amount 100% Drag Brake 100% Crawler Full-On Drag Brake Ramp Disabled (Intantaneous) Brake will not hold the truck. It isn't any better than the HW1080 I just replaced. I have an AXE 550 2700kv in a 9lb TRX and if the tires will stick, the brake will hold. Hoping for the same performance in the Capra. Any suggestions? Appreciate it. |
Re: Have tech questions? Will answer. Throttle curve ? Start power ? Punch? JRH s video shows how all work together Hang up and Drive |

Re: Have tech questions? Will answer. Crawlmasters have weaker brakes then a torquemaster plus Tha Capra has taller gears which make it harder on the drag brake. Softer foams might help. Too much drag sends power through the motor. It basically just turns into heat, that might become an issue. The Holmes hobbies esc's had an active drag brake. So maybe they would hold better. I'm not an expert on those. It's probably just be the crawlmaster you're using with the Capra gearing. __________________________ Handy gearing spreadsheet |
Re: Have tech questions? Will answer. Thanks for the response. I took my HW Axe 550 I had in my trx and put it in the Capra. That brake is super duper and with a 9t pinion the 2700 has tons of low end. Problem solved but it was disappointing. I’ll likely put the Mamba X in the Trx and add a pro puller or something like that. Cheers Sent from my iPhone using Tapatalk |
Re: Have tech questions? Will answer. Just came across this vid of a torque pull test of the SHV500V3. This servo pulled exactly what it claims. Only a couple of servos have pulled anywhere near it's claims in the many servos he tested. My questions are, is his test rig trustable on what it is reading? And, Is there an industry standard test? And How do you at HH test them? And btw, this is my next xmaxx servo when the 2085x dies... https://youtu.be/trgpe-b84PM |

Re: Have tech questions? Will answer. I believe this guy is an honest reviewer. I'm actually debating with someone about his test equipment. He is saying the bend in the servo pull arm is causing lower readings. I was wanting to know from an expert if his rig is accurate, and how they do it at HH.
