suggest a ratio for a BRM 13x1 for indoors please.

I don't know BRM's too well. but Mr Ward is always going on about gearing them up or something like that.

I ran a 10x2 on a 16 with the standard spur at the worlds, this was quite a big dirt track but my car was quite undergeared. the motor seemed to like it though.

as a guestimate/starting point I would try something like an 18 or 19 maybe. see how that goes.

but like I said, I know Glyn Ward has some idea's with his motors and gearing them and it does seem to work for them too.

hope that helps

Ive ran a 21 all year on a BRM 10x2 in 4wd. Glyn always said gearing up helps and it does with his motors ive only ran me 13 x1 in 2wd but I run about a 27 ;D

13 x1 in 2wd but I run about a 27

Was that a Losi XXX ?

What's the internal on a Losi XXX ?

2.43:1

[Matd]

Ye a XXX I ran as high as a 30 on a 78 on a 13x1

Have a look in the modified motors section...

I was told indoors to be running around 8.5:1
