correct me if i'm wrong but the specs of the Duratrax "ICE" charger said that it can charge Li-Po and Li-Ion cells

StepPins

Can anyone tell me which steering arm gives the most ackerman effect?, the "A" arm or the "B" arm?

Thanks from a MTX-3 noob from Hawaii

You are correct. It will charge both Li-Po and Li-Ion cells but only the 3.7v ones. If you overcharge a Lithium cell it will explode. The most extreme case I have read about is a workshed being burnt down because of improper charging.

You cant charge the 3v Li-Ion with any of the current chargers on the market. They have a special charger which you can buy with the cells but it only holds 2 single cells pushed into it. no use for us using made up packs.

The A steering arm gives the most ackerman.

ok also thanks for the info

No problems. Im going to get one of the 3v wall chargers and strip it down. Going to rewire it to hook up to Futaba J plugs for the job. Believe it should be possible.

Regular Price $29.99

Sale Price $18.99

this is one that I use They also make a chip that won't over charge and won't let them discharge to far, nice when you consider you place them under your gas tank. http://www.batteryspace.com/ HAYWYRE

i need some suggestions for a technical parkinglot track. our back stretch is about 150ft and the rest of the course has small straights but many corners.

i am running the stock pulleys and gearing, ther was a guy running a 22 / 50something first gear and i forgot the second but he was really getting it. same car and motor as mine, so i know it was the gearing and ratio?

out of the corners i seem to be a little slow also

I thinks ur gear ratio is around 6. It is too big for track with 150 ft stretch. Use smaller gear ratio. I suggest...... 1st speed ratio 7.5 to 7.2 and 2nd speed 5.2 to 5.0. If u want more pick-up use 1.0 pinion and spur. Adjust d 2nd speed to engage at 50-70 ft. For 5 min heat or 1 tank play, u can run with low end a little lean but for final or continue running for more than 2 tanks, make sure d low end is a little rich and dont 4get to test d 2nd speed after retuning, coz d 2nd speed gear engage timming may change each time u retune d engine. Hope its help.

Thanks for the info on ackerman!!!

With 0.8 modules use 20/58 in first gear, and 25/54 in second gear.
With 1.0 modules use 16/47 in first gear, and 20/43 in second gear.

Readjust your carb and gearbox accordingly.

What is a good front diff set up? I have been running the box stock setup with ok results, I just HATE the one way up front. I have driven way too much off road and like the break too much. I have all the parts and peaces, I just need a "basic" set up for it.

thx

I need this setup too...... I'm quite tired driving with front one way. I think cornering stability is more valuable than faster cornering speed.

Why front one way is faster than a ball diff ? Is it faster at straight or mid corner speed ?

InitialD

A oneway will always have faster cornering speed. Faster because better off power steering characteristics. On the straights, a oneway or a diff will have the same speed.

Remove the gears from the front diff and insert the Kyosho RRR locker. The solid axle is far better than the diff.
