spoiler activation speeds?

[Riley 0]

ive done a search and havent found exactly what im looking for.

 

id like to change the speed at which the spoiler raises to 30mph,but i dont know which resistor i need or where to get one.

 

ive had a look at maplin and theres just too much crap to look through!

 

anyone help? oh and by changing the raise speed to 30mph,what will the drop speed be?

 

cheers,neil. :)

cheers m8,seen that but it dosn't list a resistor for 30mph and im crap with numbers :oops:

Ask the guys at Maplin, I bet one of them will know ;)

cheers stan,just had a brainwave concerning an old factory fit poxhall corsa radio too... :lol:

ok,heres a question for ya :!:

 

if the standard resistor in a late relay is 0.25w,would i be ok using a 0.2w to replace it? think it should be ok?

Resistance = 1430045.45 + (30)(-18045.45) = 888.68K Ohms

 

The closest preferred resistor values are:

 

1% tolerence = 887K Ohm (30.09 MPH)

5% tolerence = 910K Ohm (28.82 MPH)

10% tolerence = 820K Ohm (33.81 MPH)

 

You may get away with a 0.2W resistor but it's generally not a very good idea to under-rate components. Especially in this case as the spoiler will become more active with the new resistor.

thanks for that m8 :D

 

mmmm,may have to see how the lower wattage copes. :oops:

 

and i understand that there isn't a resister available with an exact value near 30mph?

ps:any idea what the drop speed would be if i was able to get it to raise at 30mph?

 

cheers,neil.

Reading the above american link the chap seems to suggest that the lowering speed is around 30mph lower than the raising speed. Mine goes up at around 48mph indicated and down around 8-10mph(ish) so that would seem to bear this out. That means if yours goes up at 30mph it might never go down ever again!!! Ohh Err missus! :lol: :lol:

cool :lol: :shock:

 

this is my next job to tackle i think,looking into a potentiometer,will have to see if it works on the lowest setting!

You want more accurate than 30.09mph? You're a tough customer!

so there is a resister with the values...1% tolerence + 887K Ohm bcstudent?

 

cheers,neil. :)
