Lone-wolf Posted February 5, 2021 Author Share Posted February 5, 2021 It may well end up there, really want to keep with the plan of 4s brushless, should be a rocket 1 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 5, 2021 Author Share Posted February 5, 2021 Contact foam tyres and a larger pinion (21T) ordered 1 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 6, 2021 Author Share Posted February 6, 2021 I am still waiting on parts for my project, motor, esc, and wheels, i have chopped the Tamiya discarge plug and soldered an XT60, got the ride height about right, i think i may do a speed run with a 15T brushed motor and larger pinion on 3s lipo before the brushless goes in Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted February 6, 2021 Share Posted February 6, 2021 guess that will give you a bench mark to start out from Quote Link to comment Share on other sites More sharing options...
Redback Posted February 6, 2021 Share Posted February 6, 2021 Sounds like a good idea, going to make a guess and say you will get just over 30mph on stock brushed. If you get to 50 on brushed i'll eat my hat. 1 Quote Link to comment Share on other sites More sharing options...

GMballistic Posted February 6, 2021 Share Posted February 6, 2021 My guess @Jack Reacheris similar to @Redback at a little over 30mph. I'd say 35mph on 3S, pinion gear dependent. Not sure how your suspension is set up but one thing you want to try and do is adjust it so the car has a rake angle with the back being slightly higher than the front. Then you want to ensure that the rear cannot go lower than the front, ....you can do that using limiters in your shocks. E.g. just add a small piece of pipe on your shock rods to limit the travel. You want to do that as when you accelerate the car will want to squat down. If the rear end of the car can go lower than the front then it will encourage air to go under the front creating lift. Worst case the car will flip. 2 Quote Link to comment Share on other sites More sharing options...

Worst case the car will flip. so far it looks like the rear has a bit more travel, and the front is light so i feel the front will push down more than the rear but i can put a couple of pre loaders in the rear, if the 120 esc fits and i can get it running how i planned it will be darn quick, but back up plan is a 540 brushless set up on 3s and that might just crack the target 70mph ........maybe Quote Link to comment Share on other sites More sharing options...

Regarding the 540 brushless set up on 3S cracking 70mph definitely achievable gear ratio dependent. My 1/12th Serpent S120 LTX ran an 87mph at ROSSA last year on 3S. 1 Quote Link to comment Share on other sites More sharing options...
Redback Posted February 6, 2021 Share Posted February 6, 2021 (edited) Please co me tell me how to make my car fast @GMballistic 🙏 Its another cheapish chassis with over the top electrionics haha. Not having much luck with pinions and spurs. @Jack Reacher said you can tell me how to make my car faster than his* 😉 😁 Edited February 6, 2021 by Redback *might have been a dream 1 1 Quote Link to comment Share on other sites More sharing options...

Pinions and spurs right now mostly, i dont want to derail Jacks thread as whilst similar setups i have no idea what the strada driveline is like when it comes to spurs or aftermarket parts. Please pop past if you get a moment, i go into it in a bit more detail there. Thank you. Jack looking forward to seeing how it runs, are you waiting for the contacts before taking it out or going full stock?

Lone-wolf Posted February 7, 2021 Author Share Posted February 7, 2021 More expense, so due to a paranoid feeling that the 3660 and 120 just wont fit (measured up a couple of time) so ordered a surpass 60amp esc and F540 3300kv motor will go with 23t pinion and 3s lipo Quote Link to comment Share on other sites More sharing options...

Redback Posted February 10, 2021 Share Posted February 10, 2021 what size pinion did you go for, can you drop the spur gear size from stock with ease? i was looking at the strada spur looks to be 32dp and a low t count, so should be pretty good stock imo, with room to improve if needed Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 10, 2021 Author Share Posted February 10, 2021 not got as far as spur gear, went for a 23T pinion to see how it works Quote Link to comment Share on other sites More sharing options...
Darren Frosty Posted February 11, 2021 Share Posted February 11, 2021 the stock strada gears are mod .8, the after market HSP metal spurs are mod .6 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 13, 2021 Author Share Posted February 13, 2021 Was hoping to do a stock speed run to determine standard speed benchmark but as you can see from this picture i have just taken, looks like i have to wait a while for the weather to improve 1 Quote Link to comment Share on other sites More sharing options...
GMballistic Posted February 13, 2021 Share Posted February 13, 2021 Nah just run it @Jack Reacherthe motor/ESC temps will be nice and cool that way. 😀 😄 We've got the same here. Been snowing since early morning and still going albeit really light snow so not causing any issues for people yet. 1 Quote Link to comment Share on other sites More sharing options...
