4.2 motor and possibly 200 mAh batt bulk buy, you in?
I may be doing a bulk order from toyeast, and was wondering if anyone would pay 7.50 for one of each, the king and pro 4.2 motors. I might also do a big 200 mAh battery order. would anyone be intrested in either of the two? a single order from toyeast to USA after s/h alone, the 4.2 motor is roughly 10 bucks, and its a long wait for shipping.
*edit* the 200mAh batts will probably be about 3.50 per.

Lithiums?
Has anyone tried Lithium Ion/Lithium Polymer batteries on these things? You can find them in old cell phone battery packs. A surplus qualcomm 1-cell pack is only 5.00, so they're affordable. Of course, a charger is about 30.00 (I have the Apache 1-2cell for my R/C plan), but it's well worth it-and you may be able to find a Qualcomm charger to go with it.
The benifits of going Li-ion are immense. A single 700mah cell will give about 4x the duration of a 200 mah NiMh cell, and it delivers 3x the voltage. Although a bit wide, modern Lithium Polymer packs (such as the E-Tec's and Kokams) can deliver even more duration, with a single 1200 Mah cell weighing only 23 grams! If this seems a bit large, there are also 340 mah cells that would fit very nicely.
Of course, there are some tricky problems with Li-Ions/Li-Po's. Both batteries (Li-Po is really just a better kind of Li-Ion) cannot be drained below 3 volts without damage. Although a simple zener diode will fix this, another major disadvantage is the charging time-Lithium batteries should be charged in no less than 1.5 hours. Of course, with 2 chargers and 3 lithium packs, you could race indefinitely!
As a side note-has anyone tried those N-20 motors found in E-chargers in these? They are very cheap, and although a shade large, they should give a decent speed increase. Also, has anyone found metal gears for these things?
Just a few ideas-but I have used Lithiums with great success, and want to see what y'all can do.

Lithiums are great!
Triple the speed...
four times the duration....
And they explode if you crash them too hard!
