Since you are very new, PLEASE go to your local hobby store and get whatever charger they recommend you to get for fast charger and slow charger, that way, you can always ask them for some technical advice, immediate return (if u need it), like what socket to use for your pack, etc... Be prepared to paid a lil more but you solve all your frustration getting answer from different opinion people over here.

Anybody worn out the 2-speed one-way bearing? My 705 is about 3 or 4 gallons old. The one-way bearing has developed play, and I can hear it skipping when the engine winds out. It has nothing to do with lube; I already tried cleaning and re-lubing. Is this normal?
Do I need to replace the one-way beaing (902411) or the one-way and part number 902412?

The one way bearing on the 2 speed adapter itself is the same bearing that was on the Impulse and made by INA in Germany. I believe it's the same too on other cars as well. Most of them use one way bearings from INA. The one way bearing is for an 8 mm shaft. The bearing part number is HF 0812. I bought one as a spare and it costed about approx USD 8 a piece. Handy in those cases if you need to replace one of the roller pins that goes missing.
I thought I read somewhere in one of the mytsn forums that one of the ways to "revive" the one way bearing is to rub the shaft of the 2 speed adapter (902412) with an emery cloth. This gives the shaft some surface roughness to let the one way lube stick on it.
If you can get anybody who has the same 8 mm flange adapter from the Serpent or from any cars for that matter and test and see if it slips. If it does not, then your current 2 speed adapter is toast and nothing wrong with the one way bearings. Else, if the one way bearing is really toast, replace the 902411 one way bearing.
Hope that helps

oh yeah the spring was too soft for the track (yellow), tires weren't trued and too big(66mm), ride height was too high (7mm ). the reason was i really didn't feel like scratching my new chassis.. and i was only there to break-in the motor and the drivetrain. but it was sad to see my new body getting trashed due to traction roll.
i didn't think my droop was too much off. 0 for the front and 7in the back.

No, I'm not from SG. A little up north
I believe you can also go the STS webpage and download the small utility ODR Tool V1.2.

Taking the stock 705 / Impulse PRO with 15T/18T pinions and 50T/46T spurs as an example;
Front Internal Drive Ratio = 24/18 x 24/16 = 2
Rear Internal Drive Ratio = 46/23 = 2
Spur / pinion ratio (1st speed) = 50/15
Spur / pinion ratio (2nd speed) = 46/18
Front / Rear Tire diameter = 62 mm (foams)
Final Front Drive Ratio (1st speed) = 2 x 50/15 = 6.67
Final Rear Drive Ratio (1st speed) = 2 x 50/15 = 6.67
Tire Rollout Front (1st Gear) = (pi) x 62 / 6.67 = 29.2 mm per engine revolution
Tire Rollout Rear (1st Gear) = (pi) x 62 / 6.67 = 29.2 mm per engine revolution
Final Front Drive Ratio (2nd speed) = 2 x 46/18 = 5.11
Final Rear Drive Ratio (2nd speed) = 2 x 46/18 = 5.11
Tire Rollout Front (2nd Gear) = (pi) x 62 / 5.11 = 38.12 mm per engine revolution
Tire Rollout Rear (2nd Gear) = (pi) x 62 / 5.11 = 38.12 mm per engine revolution
Both front and rear tire rollouts are equal and therefore, the overdrive is said to be 1:1 i.e. no overdrive. If front tire rollout is bigger than the rear, then it is overdrive. If the rear tire rollout is bigger than the front, then it is underdrive. Some people purposely set the car for overdrive (or underdrive) because it suites their driving styles.
Assuming there is no friction loss in the clutches and the engine is able to rev 36,000 rpm;
Top speed achieved (2nd gear) = 36,000 x 38.12 = 1372320 mm / minute = 82.3392 km/hr
Hope that is pretty clear [/B]
