hey man, how did u put the 1/18 scale motor in there? i have a spare tekin laying around so i was wondering. i could put it to good use =)

Make tests with larger battery, but always check the temperature of the motor and esc when tested with a digital thermometer, if it exceeds 90 degrees of engine you have to detach, and the esc does not exceed 60 degrees that are already so many

Good idea. If I can find a power supply, that would be nice to test with, before trashing anymore lipos.

[gandalf2tamiya]

attention, a regulated power supply adjustable from 0 to 30V and 40A is very expensive.

I thought I too, I have tested in the laboratory but are generally limited to 2.2 A of maximum delivery.

it less expensive for me to buy two lipo 5000mAh 20C used, which are basic needs.

Now I think that engine uses them at least 10-15A

[kargidesign]

I wont buy a supply of course dude, thought I may find one in university. But now you say, they are rare :)

I have just finished soldering second 4s, I will try once again tonight.

Yes, the motor is rated 12A max, but lipos can give 4A at peak.

[gandalf2tamiya]

you want my advice?

I will do so, before you burn these little lipo

will use the beat from 1.16 per car to do a test bench, so you can see a Amper multimeter how use your engine, after that choose the right one for your little lipo.

I think that those batteries in series that you pull out a few mAh, that engine uses a lot more amps than they have.

[kargidesign]

yeah dude, this motor pulls lots of current. And I am aware these cells are small for this motor. But I am not expecting 5 min runs, just a few fast passbys.

Honestly I got exticed after 4 months, I should cycle the lipos a few times, before shooting this. Got a little rusty about rc's too. But will make out, next week.

sorry the site is in Italian but exists in all languages.

tomorrow looked for her to adjust the trim with precision up to 16.8 V.

I've got so many if it works I can also send it to a single price, but that we speak in private to the forum

[gandalf2tamiya]

back to the subject

connecting a tester to see one for the voltage and amperage when it absorbs.

I were you I would wait to test until you have the proper equipment to do the test.

contact me if you need material that will be glad to help ok?

hello I return to my micro-speed eheh

[gandalf2tamiya]

only the lipo was damaged or anything?

did you short circuit?

How?

[kargidesign]

I suppose, I was hard on lipos, for the first run. Overdischarge them. I have a few old but good cells, I will make a second 4s next week. But, damn, I am very sorry for the pack, it was a nice one.

[gandalf2tamiya]

I watch with interest, compliments always

[kargidesign]

thanks dude.
