Motor Brushes & Spring Combo's for 4 cell

[Glenn Atterton]

What set-up combinations are favourite at present ?

some orion/brm 10/30's and some low tension springs...

i use corally black springs personally.

orion 10/30's with blue/7oz. springs. What I've always run.

[Big Jimmy G]

I've always run mine exactly as they come from the factory - same brushes, springs and timing.

I guess this is a good starting point - what happens if you go for softer / harder springs or different brushes? Does tweaking the springs in a pair of pliers have the same effect as softer springs?

as a rule i never "tweak" springs... as if you want to re-create the same performance in a different motor you have a lot of in-accuracies and alot of varibales.

if you hop-on over to the trinity forum...and look under the thread names "switchblade".... then on the 1st page i explain about springs.

i always use the 10/30's... i get a whole weekend out of them in 10turn motors!!!!!! i guess you could buy really expensive brushes and chnage them every run... but at 2quid a pop and they can last all weekend with very good power... why bother??? ???

hope that helps mate

Looking @ Trinity site and they go for 4383's for 1/12 scale use.

Anyone using them?, your thoughts on these please

[Roger Manwaring]

Reference the 4383's, these are generally whats used for the best performance. depending on how hard you drive these should last approx 3 runs at a high level of performance and maybe more, you will probably need a skim in between. After the three runs take off and keep them for club use. Regarding springs, last year a fairly soft spring like the Trinity Gold or a slightly firmer Green spring was used but with the extra Joules this season maybe an even stronger spring may be favoured. Try it!!
