Does anybody know the ratings for the rayspeed springs, or were I can find that info?

And also a good starting droop setting, for carpet with say 60mm diamieter foams. on a CGM

I just purchased a Hitec BB77 servo which is the low profile servo and I was wondering what kind of servos everyone else is running. I was also looking at the Futaba digital low profiles, but Hitec had better numbers and was alot cheeper. Any comments would be welcome.
Thanks
there's so many things that can cause glitching, why not that one... Any metal vibration can be a source of trouble...

I run a KO 2113 7.2s fet servo... 0.06s for 60 deg, 130oz.in, woo-hoo! I've only had bad experiences with Hitec stuff, I quit buying their products a couple of years ago. I heard they made great improvements, but I'm still skeptical...

Thanks Paul,

I have just ordered a Futaba S9550 and it may be a bit slower than yours it is still fast and it is a metal gear ball bearing low profile servo with .11 s for 6 deg. and 86oz torque. that is enough I think for a TC. I will take my 93457 and make it my spare for my Inferno K3. I was still wondering were to buy those noise reducers than clip on the negative wires. Does anyone have a place to buy them and an actual product name. Thanks....

Stephen

Heh guys, been a while since I've touched mt SD. I have a question on gearing. I'm running 72 (all 48 pitch) tooth spur, and using a monster stock pro. What final ratio should I shoot for? I was thinking around 6.3 ish? BTW, the track is outside, decent traction and medium size and sweeping. I'll probably run a one-way, so braking will be low and not add heat.

Actually 6.3 sounds too high, maybe around 7.0?

Edseb,

I usually run as close as possible to a 7 with my monster stocks fyi.

Shooky,

I think that speedtechrc.com has the magnet clamps and i believe that yokomo was packaging them. Maybe give them a call.

Thanks for the tip. I'll probably start with a 24 pinion and go from there. That gives me a final of 7.059.

I would start at 7.5, gear up or down from there.

Stephen,

the 9550 is a great, bombproof product (actually it's WC in Surikarn's 414 I believe), and in the SD, when rotated, it really helps free up some space for the radio. As far as servo speed is concerned, some racers actually prefer slower ones... I know Jukka Steenari's tried some slower KO servos and he likes them better because it prevents understeer (the front tires don't slip because of too fast angle changes). I'm not Jukka and I like quicker servos better

btw... there finally are some pics of this last WE's race... last round of the Swiss Nationals... My Yoke took 2nd in the 17T class, it was on rails... The guy who took victory was an ex 12th scale national champion who did his come back in mid season after he quit for a few years... so I guess he was a worthy contender
Anyways, here are a couple of pics from a website that did a page on my car...







The car was absolutely perfect, stable but with a lot of steering. I used a funky front shock position, on a rear shock tower's body mount hole... front shock were near vertical and steering was *very* direct. The car was fantastic and gave a good run for their money to all the guys who sold their SD's when the Pro4 came out For those interested I can email a setup sheet (Orion's B-type rubber on carpet, 17T), it's too big to post here.

Later,
Paul

Note the 5th body post, btw... just drill the shock tower and you're set. I thought it really helped removing parasitic body vibration effects...

yes it does... it prevents the body from flexing and rubbing on the front tires under heavy turning/breaking, it gives a tad more downforce on the front at high speeds, and best of all, it considerably lengthens you body's lifetime (no more front cracked fenders)... My paint jobs are average because I hate painting bodies... the less often the better!
