- A walk through of a day of shake down testing with a new chassis on a new surface, using the linear staging technique and top down tuning.
Hope this helps someone. ended up being a lot longer than anticipated.

Hello,
I want to express my gratitude for sharing your informative video on "DRK linear stages and top-down tuning." It has been incredibly helpful in getting started with tuning, and I truly appreciate your effort in creating such valuable content.
I was eager to learn more about your own car setup since you mentioned using a Bullet chassis. I'm curious if it's based on the Losi 5.0, Losi 22S, Traxxas Drag Slash, or DR10 platform. Additionally, details like the transmission you're using and the tooth count on your pinion and spur gears are all essential factors influencing how one tunes their car. I understand that taking the time to answer questions like these can be demanding, especially when creating content is just a hobby.
In advance, I'd like to extend my thanks for any insights or information you can provide. It's essential to recognize the dedication content creators like yourself put into their work. I thoroughly enjoyed your video and have already subscribed to your channel, looking forward to more of your content.
Keep up the fantastic work, and thank you once again for your contributions to the hobby!
I honestly can't remember a ton of details, because I've been indoor track racing. The chassis is the b6 varint. I actually use the team associated carbon infused laydown gear box. I think I was running 3k diff oil front and back, but I honestly can't remember the piston holes..I wanna say 2x1.6.. but that makes a difference. I know a lot of people run lighter oil as well with great success. I think at the end, after this video, I had tried 80 front / rear.
Gearing is tricky and really depends on your battery capability. I run a 6600kv 4 pole motor, and I think 90/27 is a good place to start. If you stay above 6.5v, you can add timing or maybe try less final drive ratio(bigger pinion or smaller spur).. but usually staying somewhere in the 8.4 - 9 fdr suits most people. Fdr is spur / pinion x gear box ratio. In my case, associated uses 2.6. 90/27 x 2.6 = 8.66 fdr.
Losi uses 2.43. Traxxas 2.72, I believe.
Thanks for your kind comment.
@@ExaltedRC Thank you so much for taking the time to share your valuable knowledge and insights with fellow RC enthusiasts. Your input regarding your experiences with the B6 Variant chassis and the Team Associated carbon-infused laydown gearbox is greatly appreciated.
Your detailed information about the diff oil, piston holes, and gear ratios provides a fantastic starting point for those looking to optimize their setups. It's clear that you've put a lot of thought and experimentation into your RC racing setup, and your willingness to share this information is a testament to the helpful and supportive nature of the RC community.
Your explanation of gearing and the formula for calculating the final drive ratio (FDR) is incredibly informative and will be a valuable resource for RC enthusiasts looking to fine-tune their vehicles for different scenarios. Knowing the gear ratios used by other manufacturers like Losi and Traxxas is also a helpful point of reference.
Once again, thank you for your generous contribution to the RC community, and for your gracious response to our comment. Your knowledge and willingness to help others are what make this hobby so enjoyable and fulfilling for everyone involved.
Sticky tires, or just cleaned and warm? I ask because ive been attempting pure runs. I know i can gain quite a bit if i can just give them all the beans from jump, but the most ive done is clean, prep with softener and allow to dry then burnout. The drk is in my stock slash, the only car i hadnt modified yet, and the slowest. My best 2wd clean run has been 2.36 on my dr10. Ive done extensive testing, but havent been able to eliminate hard pull left and then jump right. She likes to get squirrely.
Kindly, did you ever open the gns records to compare them with your data?
Because I think that the skyrc gns does not give the maximum speed because it stops before the run is completed!
Are you running dry tire, or heated and sticky?
I am trying a different setup but only managed to do 1.98s with a speed of 151km and 2.44g force with a 7s 6000mAh 100c lipo batteries on a Limitless that weights 6.7kg with a Hobbywing max6 g2 combo and 1650kv sensord motor with rubber wheels.
Now I am trying a v2 Limitless with same batteries but I only made 2.08s 2.41g 151km with xlx2 and 4070cm tp motor.
It seems that the car is faster but I can not make a better time.
Unfortunately with my escs I can not see that type od data that you have but they have different graphs and one with one turbo timing and the latest the tp is sensor less.
It has lots of power but lots of spinning too!
I hit 2.63 on 6s on my v2 with a just for shits beans run. Only did it one time, and didn't prep at all. I'm certain it can do under 1.5. I'm running a tp1400 on that car. Castle link system and gnss will give you access to all of this.
@@reallythough4591we do not prep and the surface of the road is not that good so it is a bit difficult to go very fast in just a short distance.
We tried in another road with better grip but they brought us the police so we cannot try again there unfortunately, because it was good and we were improving and best time we got was 1.89s with 8s on a v2 with xlx2 and tp 4070 2700kv 7s motor.
Yesterday I tried the same car for a speed run with same setup for drag and managed to go up to 210km in 2.2 seconds on full throttle because I gave it a five seconds delay from the radio to smooth up the run!
@@josephcaruana9165 I have a little ng country road in front of the house
👍👍
Dry tire or prep?
Prep of course
OG Tp effects 1st stage only ...Tsr Tp effects the transition time between stages...RS no clue
Apparently with current software, it affects all stages, per Maclan team lead, Ian.
Is the ESC unlocked with this setup?
Sorry, yes it was. Unlocked allows you to bring in timing during the early stages and run 4 pole
