speed run

Hey guys, i just wanted to show and get your opinions of one of my speed runners. It has a tp power 3640 scm 3570kv motor and a hobbywing max 8. Servo idk but it is fast and it last long so far. Is already has done 95 mph but around 95 mph it starting to act like a plane, but it has way more in it!

idrk??? what do yall say>>

I just got a new Vendetta and I would like some tips on what to tune for ideal speed runs. Any help would be appreciated!

Hey, I'm speedrunning my Talion EXB 6s. I'm having a really tough time with the front center driveshaft. At high speed, it is vibrating so badly that the diff input bearings keep shattering. I'm running M2C diff input cups (true and balanced), Scorched Titanium driveshafts (no bends etc..) , and...

So I now have a new Limitless V2 that needs a power plant. I started researching TP motors but I now have more questions before I hand over my cash and order it from overseas. It's by far the most I will have spent on a motor or any individual RC part in fact, so I want to ensure I get it right...

im looking for a rc body that will fit the senton. because my senton body is all cracked up and i need a new body.my senton is lowered to the ground so im looking for a race car body maybe or maybe a racing truck. leave links if you have any suggestions thanks

$350 + shipping. Arrma Vendetta Speed Run roller. $800 worth of quality parts; I did not skimp out on this build. The car was babied and has only done 4 shakedown runs, the fastest one being only 78mph on 3S. Shims and O-rings were used throughout to eliminate slop. It's built for speed and...

I am probably going with the 8s Spektrum setup with the 1250kv motor and 160 a Esc they have on their website https://www.arrma-rc.com/de/product/1-7-limitless-v2-speed-bash-roller/ARA7116V2.html but I have no clue at all which transmitter I should go with since they have all parts to complete...

Hey guys! If you're looking for an RC speed calculator, take a look at the one we just built on RCTalk. https://www.rctalk.com/rc-tools/rc-car-speed-calculator/ The calculator should useable across all devices. Plus I've reached out to a few of the members here for initial testing and so far...

Does anyone have experience with other RadioLink Receivers? I'm using the Radiolink RC6GS V3 on my Limitless. I have a new build coming with an Rlaarlo AK-917 and need to add the radio. The current receiver, shipped with the transmitter, is the R7FG. Which is overkill with 7 channels. There...

Hey guys, I'm trying to see how fast I can push my Talion EXB on a stock ESC and Spektrum 2050kv motor. I'm hitting 85mph consistently, without any heat problems on Sweeps Road Crushers. These wheels are nice, but they're insanely heavy. I'm considering 1/5 GRPs, but I've heard they're heavy...

Ever wanted some real aero components for your Limitless instead of those huge drag walls they give you? I did.... I am what I guess you call a hobbyist aerodynamicist and an avid 3d printer. So I set out to try and create some real aero components for my limitless. I'm not promising that...

I’m thinking about using limitless v2 diff gears in my stretched typhon 1721 xlx2.or should I just leave the stock gearing in

Tyhon 6s drag/speed run build

Almost ready

Wide typhon 6s she still under construction but its goin to turn out nicely

I would like to introduce to you a new project of mine. This one is going to be called Aero Max as the goal was to reduce the aerodynamic frontal area of a 1/7 scale-sized car. It will be a speed runner so I have placed it in the speed run builds part of the forum. This project has 3 phases...

I am planning some pretty big upgrades for my arrma limitless, some being a carbon fiber chassis upgrade, motor mounts, driveshaft stuff and a new motor to handle 8s. I’m planning to get the hobbywing 800kv 1:5 motor with the max5 v3 esc alongside it. What would be the best way to cool this so i...

Hello my friends, new to the forum. Just did an upgrade to 8S and looking for tips to keep the car on the ground. I'm looking for minor bashing but mostly speed runs on a parking lot near my home. Just want to get some decent speed and I understand the risks of going over 100+ but my goal is...

Hey all, Finally was able to measure my first asphalt speed run > 70.9 mph with a 20t pinion. Really that's the only power train upgrade but I also have: Zeeee 3s 100c Batts 20t pinion gear 2 hotracing fans on the motor 1 high-powered fan on the esc 35kg servo Aluminum suspension arms...
