E-Maxx 3906 LiPo Battery Upgrade

July 30, 2018 by justin 1 Comment

My good friend Joe has an old E-Maxx – not wanting to miss out on any bashing and crashing fun, I had him dig it out. It’s an oldie but a goodie. A 1st Generation E-Maxx with dual motors, dual batteries and a 2-speed transmission. It’s the one with the chassis that looks like this:

It’s also a bit of a relic. NiMH batteries, brushed motors, and AM radio aren’t exactly state-of-the-art. But I don’t want to upgrade everything, I just wanted to get it back on the road – so where do we start?

Power Supplies

January 16, 2018 by justin 3 Comments

This little power supply from Ready Made RC is a tremendous bargain. The specs are fantastic on paper – but it doesn’t pack quite as much punch as advertised. I have two large capacity (5200mAh) 6S batteries that I use to power my electric lawn mower. This power supply buckled after just 2.5 charges 😞 Here’s how it went…

Converting to XT60

December 4, 2017 by justin 4 Comments

I did quite a bit more flying this summer than I did rc car racing. As the weather turns cold flying will be limited to golf dome outings with the local electric club and indoor FPV. In Minnesota the on-road guys drive on carpet indoors, so it’ll soon be time to race. One thing I’ve grown to like that is commonplace on quads and planes is the XT-60 connector. So I decided to upgrade all of my cars and even my rocket launcher to it.

Technically, an XT-60 pair is 2g heavier than a pair of Deans connectors, but with all of the other advantages, I’m still switching.

Cheali Charger – free 4-button charger upgrade

October 9, 2017 by justin 2 Comments

If you have one of the ubiquitous “4 button chargers” you can likely upgrade the firmware to Cheali Charger. You’ll have to do some hacking to get there, but if you want to add features like LiHV and NiZN charging, and have 30 battery memories, it’s the way to go.

Example chargers that are eligible:

  • Imax B6
  • Imax B6 clone
  • Turnigy A-6-10
  • HobbyKing ECO 6-10

Scout CX Battery Mod

September 11, 2017 by justin Leave a Comment

I’ve tried adding an upgraded battery to my son’s Scout CX in the past, but it’s designed to only accept the tiny 70mAh batteries it comes with. After upgrading my Inductrix to a larger power connecter, I had two donor batteries to experiment with… So I took my old Inductrix battery lead and made a lead extension.

Inductrix ➡ Tiny Whoop ➡ Power Whoop

August 28, 2017 by justin 5 Comments

I had been eyeing the Inductrix when it was released in 2015. The “ducted fan” design interested me because it was quiet(er), and because I could bump into things indoors with a better survival rate.
