Guys have been finding that they can use softer springs too. The 1.0 springs act like 1.1's with this set up. It looks like a good set up, and seems to be very smooth. It worked good on the MG66 - yes ?
I will be running my MG all the time this next season. I was going to run another motor for club days and keep the MG for bigger events, but I figure why have a motor like that sitting in the tool box gathering dust. Go hard with it and if it wears out, just buy another one Lifes to short to settle for second best when the good stuff is right at your fingertips
I tried the clutch because I have been having issues with the 3 shoe clutches eating bearings ..I found a discussion on this topic and the general opinion was that running one shoe with 1.0 springs and 2 with 1.1 springs means that every time the first shoe engages on it's own it pushes the clutch bell at an angle adding extra strain on the inner bearing until the other two also engage..makes sense to me especially as I keep destroying inner bearings..the 4 shoe clutches you match springs in pairs so clutch bell force is always in balance..anyway it was cheap and postage was reasonable ..came in 3 days from holland to France..spare sets of shoes with springs each time are cheaper than the RMV ones I was using and they reckon they last up to 3 gallons which is probably 5 times longer than the RMV ones..anyway it worked beautifully...I will reserve final judgement till I race with it next year but so far I'm a fan..
and yes as each shoe is lighter springs are softer..I read in a post by the guy who designed and sells it that the tension difference between his 0.9,1.0,and 1.1 springs is only 3% each time so the adjustment is pretty fine anyway..I tried 2x.9 and 2x1.0 but found 4x1.0 snappier..
Yeh I don't see me ever running my 7 port unless the MG66 dies..I am going to race next year then buy an mp9 for the 2011 season then I'll put the 7 port in the 777 and run the MG66 in the mp9..but I think I better keep that plan a secret from the missus for now
