5.5 /4.5 brushless

[big air]

am i right in thinking that most 4wd buggy's are using 5.5 and 4.5 brushless systems, is there a reason for this why not a 3.5,
and can anyone advise a on a motor for my mamba speedo

cheers

I think most people will use a 5.5 in 4wd and a 6.5 in 2wd unless they are on big open tracks and they may drop to a 4.5 and a 5.5 respectively.

As it is a 5.5 or a 4.5 will light up the tyres under accelleration, a 3.5 would just be too much to handle, if you look at some of neil craggs old setup sheets he used a 7.5 on occassions, so ultimate speed isn`t everything.

I tried a 4.5 sintered LRP at Oswestry and it was plain and simple too fast. it was not too bad on the mid and top end but bottom end was way too feirce, and coasting was pretty aggressive 'engine' braking too, even with 0 drag brakes on the speedo setting.

the 5.5 bonded LRP is much nicer to drive, not as fast, but very nice feel on the whole track.

i run a 4.5 its way too quick a 5.5 or 6.5 much better

I tried John Prices LRP 5.5 in his D4 yesterday at Bury and it was too quick, way too much for what was needed with too much power and top end and near uncontrolable.

Both my self and john agreed a slower motor was needed, I would say after using Johns system a 6.5 in both cars is more than enough, possibly a 5.5 for tracks with a big straight. But for technical tracks such as Bury metro, a 6.5 would of been dialed.

I have to say I like my 5.5 LRP around bury metro and southport - I haven't properly tried the sintered but the bonded feels great. I thought it might be too quick but its about right I think.

Now im going against everyine and saying that it doesnt seem to matter what they run a teesside from 6.5 to 3.5.

For the mamba speedo i recomend looking at the Mtronik plasma PRO motors, being sensorless they will be spot on for that speedo
