Popular Post everclear1984 Posted March 22, 2021 Popular Post Share Posted March 22, 2021 (edited) Managed to get another run in this morning and set another PB (with the body on). First run with the new body and using fuel line as a replacement for shock springs. I was unsure whether it would work at first but the car ran flawlessly and stayed firmly planted. I seem to have hit a bit of a wall speed-wise. While I did set a PB at 78, I should be well into the 80's with this gearing. Everything is still running nice and cool so I could gear up, but if it's the aero or something else holding me back I'd rather get to the bottom of that first. Any suggestions welcome 🙂 Bit dusty out, but still plenty of grip! Oh, and the body may have made contact with the tyres a little 😅 Edited March 22, 2021 by everclear1984 5 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted March 22, 2021 Share Posted March 22, 2021 Nice mate thats a good speed maybe its the tyre contact with body slowing it down a wee tad ? 2 Quote Link to comment Share on other sites More sharing options...

Possibly, but I wouldn't have thought it would have made much a difference. I'll trim it back a little, fit new tyres and go out for another run. I'm still struggling for space, I think the only way I'm going to get the place to myself is to get there for 6am and I'm not sure I'm that dedicated 🤣 2 Quote Link to comment Share on other sites More sharing options...

Popular Post GMballistic Posted March 22, 2021 Popular Post Share Posted March 22, 2021 @everclear1984 it could be your ESC holding you back or batteries. Just guessing but when I hit a similar wall with my Typhon it was my ESC that was the issue. Just asking it to provide more power to the motor than it was capable of providing. Might be worth considering a cap pack too. Another factor could be the way you're accelerating. You do need to be progressive with your trigger pull. Not having a large enough area to run may be forcing you to pull harder which then may cause your ESC to try to draw more power from your batteries than they can provide or the ESC can supply. Just food for thought rather than definite answers. 3 1 Quote Link to comment Share on other sites More sharing options...

Just food for thought rather than definite answers. I think to rule out the esc I could stick the HW Quicrun 150a in from the Savage, I guess that would be a good start. I definitely need better batteries. These are HEAVY 6000mah packs (running two of them) but only 35C. I'll look into something with less capacity but much higher C rating. Thanks as always for the suggestions 🙂 2 Quote Link to comment Share on other sites More sharing options...
Popular Post everclear1984 Posted March 22, 2021 Popular Post Share Posted March 22, 2021 Oh and the video. Just a quick one for now, I'll make a proper one soon going over all of the modifications since the last one. 1975056881_Untitled40_1080p.mp4 5 Quote Link to comment Share on other sites More sharing options...
Redback Posted March 22, 2021 Share Posted March 22, 2021 (edited) Amazing progress your making, loving watching it get faster and faster, good passes, looks like D/R needs turning down a touch as lots of steering going on or is that the car doing it itself? I think you will crack 80+ with your higher amp esc, what motor are you running now, is the castle rated for 4s? Tire wear like that is why i didnt trim the rear wheel wells out, but i have a diffrent issue of the sidewalls rubbing. Fantastic paintwork on the shell, have you re enforced the inside, this will add more weight but as @GMballistic reccommended it also helps stop the body flap about another reason the body is rubbing on the tires. I also agree the batteries might be a bottle neck, as your no got space issues, just try focus on weight for the time your running a few passes on a 3000 -4000mha should be enough for 150a draw for a couple of passes, a good quality battery will be worth it!

Thanks mate. The D/R is at about 15-20%, I'm just a bit heavy handed. I'll try messing with the expo, hopefully that will compensate for my lack of control 😅 It's a 3800kv Castle motor, rated for 3s but good for 100,000rpm so should be well within its limits. I haven't reinforced the body yet, it's on the list but I wanted to see how it ran first. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post pieman5 Posted March 22, 2021 Popular Post Share Posted March 22, 2021 (edited) Just thought id add a small bit of advice regarding lipos. From my experience you should always run the highest capacity + C rate you can realistically fit in. Total weight of the car makes very little difference to the top speed of the car, as long as you have enough space. It also helps to keep the car planted during the run. Gaining say 400g of weight to increase to like 6000mah 60C for example will always be more beneficial than saving the weight and going for a lower capacity 👍 Also agree with reinforcing the shell, again yeah its going to add weight, but the benefits will always offset this. Don't be afraid to add a little more weight to gain a huge amp advantage with the lipos. and much more strength in the shell.

For just one speed run and leaving to cool after its usually fine 👍 I'll be running a 5700kv on 4s in my mini 8ight later in the year, not really worried at all lol. 5 1 Quote Link to comment Share on other sites More sharing options...

everclear1984 Posted March 25, 2021 Share Posted March 25, 2021 Well I was up and out at 6am morning hoping to beat the dog walkers. However, the weather had other ideas 😠 I made it was far as my garage before it started raining! Still, new tyres coming tomorrow and better weather forecast for next week 🙂 2 Quote Link to comment Share on other sites More sharing options...
