Need some advise for changing from brushed to brushless

[stebedford]

I was planning on yeah, I have been down to watch you guys once but just for 5 mins. Once I get it changed to brushless ill bring it down cos i live just up the road from the goshen. Is it just sundays its open or are there any other days I can pop down, I often see a few kids riding over the track on their bikes when I walk my dog on the field there

I've tried various types of speedos and motors and would echo most of what has been said. If you intend to do regional or national events then you would need lipos and motors that are on the BRCA approved list. If just club racing then whatever you like.

Providing the drivetrain is up to it, ie you have a slipper clutch which you've said you have, something in the order of 6.5 sensored or 5500-6000kv sensorless would be about right. I have run mambas sensorless and LRP sphere sensored and would probably say the LRP just edges it for smoothness at the bottom end. I have had some cogging issues with the Mamba but got it all sorted with latest firmware. As has been previously suggested, trying to pick up a used speedo might be the best option as many upgrade regularly so there are lots available on here. THe LRP Sphere 80700 is last years model but is excellent, and there is Nosram one that is essentially a clone so I'm told (correct me if I'm wrong). The Losi sensored motors are around 50 quid and are excellent. As for Lipos well the cheapest way I believe is to buy them online from Hong Kong. The intellect branded ones (also cloned by others i believe) can be had for around 45 quid for a 3800 35C and should deliver the punch required. Other than that, make sure you use decent connectors (Deans or Corally type generally used by most).

Wow, those intellect lipos aren't half bad. You don't happen to know what sort of size the 3800 packs are, do you? I'd like to put lead under the LiPO, so I guess many packs would be too big...

We only race on Sundays, but the fence is low and the track is there all the time, so people play on it all week long. But there are no course markers when we aren't racing.

Hop along one sunday anyway - bring your car and we can advise. We can show you most of the options in action. New people are always welcome.....

They are slightly raised underneath so you could probably fit a slither of lead under. Not sure the exact dimensions, but you could find out I'm sure with a bit of research. If you go to the Bury club as hopefully I will this weekend then you can try them for size.

Thanks for the info - Im all the way down south in Southampton, so I definitely won't be able to make it to Bury, unfortunately..

If it helps:

I was running a 13x2 on nickel batteries in my 501x and am now running a 8.5 brushless on lithium batteries in my 511... assuming the chassis' perform similarly (and they do) I can assure you that an 8.5 brushless is way faster than a 13x2 brushed!

I suspect 8.5 will be well sufficient for your Dark Impact, at least to start with. I have no idea how people use 6.5's on a small track… they obviously have skills that are way, way, way beyond mine lol, I'd just destroy my and every other vehicle if I tried that at the moment!

I'm also running the Intellect 4200 LiPo saddles and can confirm they fit into the 511 just fine, as a result I'd expect the lower capacity ones to present no problems fit wise.
