elevation for stock apex mountain

[yammi4ever]

I have stretched my Attak to 151 with 8 tooth 2.52 drivers, 2" track, and am trying to figure out how to clutch it for 1000 feet and 8 to 10000 feet. Was wondering what elevation they use when figuring the stock clutching.

If anyone has any tips on where i should start feel free to let me know, and also if anyone has any of the parts that will help me, let me know.

Thanks,

kirk

Try the apex mnt./mtx stock set up.
8FS weights w/2 steel rivets w/hole in the inner and center
Y-P-Y primary spring
16.5mm rollers
45 deg. helix
White secondary spring @ 70 deg.
I have a few sets of stock apex mountain weights taken out of sleds that got boosted. PM if interested.

Run the stock clutcing on your attack but take the inner rivets out of the weights and you will have to lighten up the center and tip weight.
