Upgrading lightening spark

Post by teamfirebrain » Sat Feb 15, 2014 11:25 am

Hi my name is Matthew and I am 14, not many people will not know me as I have only been to 2 events. My ant, Lightening Spark, is well, very slow. I have been thinking that i need to upgrade it for a while now and now i have a bit of time and money i am thinking of changeing the servo powered wheels for gearmoters. Could anyone recomend me some parts, that would help a lot.
Thanks
Matthew

im using 6v 400rpm gearmotors from ebay but ive got 18mm wheels. most use the 6v 300rpm version:

300rpm: http://www.ebay.co.uk/itm/Diameter-12mm ... 1c33ebe517

400rpm: http://www.ebay.co.uk/itm/Diameter-12mm ... 1e7c2db8ad

You'll also need ESCs.

I don't know many people who use the 300rpm version, it's a bit slow. I'd say the 540rpm one are what you want. Just put 540rpm into ebay and there's plenty for sale.

And as dan says, you'll need a speed controller. There's lots of choice here, you can use servo boards, which are cheap and effective. There's also Pete Waller's boards, Bot Bitz, Fingertech, Baby Orangutan and some people even make their own. I'd recommend having a look at all the options above and seeing what fits your budget and abilities best.

Can I ask what your current set up is? It might be an idea just to speed hack the servos. I don't think I've made it along to any of the events you've been at, do you have a picture of your ant?

you have multiple options open to you. you could speed hack the servos, however they wont last as long as gear motors. i reccomend the peter waller option D2 board. it runs 2 cell lipo packs and is far smaller and lighter than say the sabertooth board. it has a servo plug so it can be used to drive a weapon as well. you'll have to ask peter about the price though. hope this information is useful. good luck with the upgrade. :D

Hi
I cant find any pictures of lightening spark but i will get some asap.
As for the setup im not sure about the batery pack or the servos but the reciever is a radiolink R7EH and the transmitter is a Radiolink T4EU.

Yep. You are correct. You would need 2 of them.
An alternative is Botbitz. I use Botbitz a lot these days. They are very good. :)
They do a dual esc here...

Most complete and value for money option, IMHO, is a fantastic Pete Waller creation. Very well built units including RX and ESC's and dual voltage servo supply in one compact unit. Can be used again and again. ( Best customer service too!) :D

you can get two cell lipos that'll plug into that speed controller from component shop. they're usually quite good.

Unfortunately the RadioLink is not DSM2 compatible so will not work with my controller.

Matthew, I think you've got one of my kits (ie from this site) I which case the servos are mg90s and not really great for speed hacking. The gear motor version of the kit I sell these days use 30:1 motors (440rpm) which are pretty fast with the 4.8v battery I supply but really to get speed you need to up the voltage and start getting into lipo cells - all gets a bit more complex.

I use controller boards our of standard servos (es3001 is a good cheap one) which are fine if you don't mind replacing the pot. You do need to do a bit of soldering.

Also, the correct spelling of Lightning might be good...unless its a pun, like its lighter than another Spark...in fact, if it is a pun, that's very good!

Hi guys i'm back!
If you can't tell I've been quite busy with school work and have had a distinct lack of money so that's why basically progress stopped.
Anyway, Now is the Christmas holidays so i have time on my hands. Also Christmas and birthday money combined mean I have a significant amount of money ( somewhere around £350). I think i have all the parts needed except i couldn't find the battery pack and still haven't found an esc. Any suggestions on Batteries or escs?

Thanks Matt
