what brushless combo

[Dickylew]

What are people runnning in there B-Max?

Im looking to upgrade to a brushless system and the losi combos seem good value at around £115.00.

Ive heard that there have been problems with the software is this the case.

Also dont know wether to go for 4.5t or 6.5t they dont do a 5.5t combo.

Is the 4.5 too powerful for bashing and possble club racing.

Any recommendation/advise please.
