May I know other than the "big" Sanwa esc which cld be had for ard $60, is there any other cheapo esc avail in S'pore? I need only something that cld take me to 19 turns.

With ESC, you get what you pay for.
Don't buy the cheapest ones, especially if you're using hot motors.
LRP & Nosram have some very compact ones (Quantum, Dominator).
Try look for the Futaba 330 too, that's pretty small.
All these would be about the S$100 mark new.
High-end stuff from KO, Futaba, Novak, Keyence, CS etc etc
would be as small for "unlimited motor" but you'll be up for
$300+ for the latest models & designs. You get what you pay for.

Hi,
need help on 2 EP questions.
1) how do you cal. the 2 gears? ( motor pinion & big gear ) so that I'm using the right gearing not to burn the motor and batt. I using 23t stock motor.
2) my TA04 front dogbone keep droping out when I hard cornering. Is it the dogbone too short??What dogbone ( brand ) and U shaft to replace??
Thanks.

i used to run 23T motors at about 6.4 gearing....
final drive ratio = (spur/pinion) x (diff/center pulley)
to prevent ur dog bonez from dropping out, simply insert o-rings inside the drive cups or the axles... the idea is to keep the bonez centered... make sure there is no binding as u move the arms after dat... or u can just go out and buy a universal...

Try getting Futaba MC330R like what WC recomended. I got mine at Winnie's 4mths back at around $95. I have the manual in pdf. Email me if @ [email protected] if you want the manual.
Below is the excerpt of the specs for the MC330R.
Eh, tronky, we met at Pasir Ris didn't we? Remember that saturday night? :P When your Electric is up, let's go for a spin.

Besides using stringed 12v light bulbs, is it ok to use a small DC fan like those cpu fans. Fans at 12V 0.7Amp. I used 2, was wondering if it's ok. Enlighten me please.

Hi Hellangel,
thanks for the reply,
but I still don't understand how you cal. 6.4 gearing??
Can you help by giving some eg.
Which is the best gearing on what motor??
Thanks.

Hi nixaad
My electric's up, in fact we are now playing electrics alternately with nitros. We'll start off with nitros in Pasir Ris before heading off for an electric session.
Bought a FF02 late last mth, realised it tail spins everywhere (worse when I change to a better motor) so I had gotten myself a TA04. Now the FF02 wld be used for rallying. Steven's gotten himself a new TA04 too and is fixing it up, both his TL01s are now "bashing" vehicles doing kerb jumps, climbing of steep inclines and believe it or not, bashing on pebbles and rocks.

i'm assuming u have a TA-04...
the TA-04 has a diff with 32T and a center pulley with 15T... let us assume dat ur pinion is 40T and ur spur is 120T...just sub these numbers into the equation i provided in the earlier post and u can calculate ur gear ratio...
final drive ratio (FDR) = (spur/pinion) x (diff/center pulley)
FDR = (120/40) x (32/15)
FDR = (3) x (2.13)
FDR = 6.39
i think 6.4 should be a good starting point for 23T motors... u may have to gear up or down a bit to fine tune to ur particular motor...

1 lightbulb sucks about 2A. Use multiples... most ppl use 10 for 20A draw - to replicate in-car use. They flatten your pack in < 5 mins.
I also have 2X "4-inch PC casefan" wired in parallel to battery plug. Most will self-start off 7.2V (ie don't need assistance to start spinning), but some won't - just gotta try. I only use these fans to cool battery & motor; if connected to a fully charged pack they will run for hours. I usually connect them to the first pack I used, then they run for at least 1hr after that.
When I connect battery to 20/25/30A discharger, I usually have the fans blowing across the battery too.
