Ebay cheap brushless

[mporter2000]

Hi all.

Looking for some brushless kit to try out.
Possibly will return to track or train up my son.
Have seen speed passion reventon combo on eBay for $49.99 from rcmart in HK.
Anyone have any bad experiences?
I've got all my old kit and my son is bashing a cat 3000.
Was planning to run brushless with my cells for now.
Thanks

i got the -R version combo when i started, but soon upgraded as the motor limit was i think 8T max ..... but it ran perfectly, i would recommend buying from uk as with electrics theres no guarantee u wont get a dud, and returning it to HK will be a pain.

Fair point.
Budget is key as this is purely dipping the toe in.
The main goal is to give me and my 4 yr old some brushless experience.
I'm was very experienced so I've got knowledge.
Can anyone give me a brushed wind comparison with the brushless?

the cheap reventon combos are great. easy to use and id be amazed if you need any faster than an 8t?
I often run a 13.5t indoors and outdoors run a 10.5t

Go for it.

The one I'm looking at doesn't specify a turn, is this right?

Sometimes.
I'm no expert, but I know some motors give a Kv value rather than a motor turn. The Kv is the ratio of rpm at a certain voltage I think (my understanding therefore is you multiply the Kv by the voltage running at (8.4v for a 2s lipo) and this gives you the max rpm.
I am happy to be shot down or corrected by those really in the know however

Not sure how to convert between turns and Kv, but the higher the Kv the higher the top speed but the lower the torque (so slower acceleration), likewise the lower the turn, faster the motor, the lower the torque

do you have a link to the one you are looking at? like the other chap said an 8t motor is more than fast enough... probably go for a 8 or 9t motor/esc combo would be fine.... i remember back in the day there was a big difference between single/double/triple/quad turn motors that you could really notice but in my limited amateur experience in running modern 2wd buggys just grab the best deal you can get on something like a 8 /9 /10 t motor with esc and you will be fine. in addition with the new tech you can add extra speed /punch via programming the esc if you feel you need a bit more speed etc... i was completely lost with it all when trying to get my head around it after a 20 yr gap.
