+1!

Also, using a higher C-rating often increases power & top speed. Higher-C packs with lower internal resistance will maintain their voltage under load much better than lower-C packs with higher internal resistance - which causes a greater voltage-drop under load.

Switching the battery types

Also when I use a partially charged Hyperion 2S LIPO (storage charge) everything works fine. Is there some kind of over voltage protection built into the esc? These cars are supposed to work on a 2S LIPO battery. Some have even used 3S batts. Any ideas?

Thanks, Kim
Our new Losi racing team we founded in our company (7 Losis 1:24 Brushless 4WD) knows the same problems when we switch the battery types back and forth.
No straight solution, but switching on and off the car and the transmitter a couple of times seems to do the trick.

Me too, although I didnt do any actual flying this season

I have ordered this little number, the dimensions seem spot on: http://www.hobbyking.com/hobbyking/s...sec_0_8kg.html

Got SMD's

Here is a little sneak peak of my bling amplifying smd led system that slots directly on to the shock towers. However I ran into some problems: It was about 4am and I just finished up (I even had them covered in CF 3D textured vinyl) and I was doing some final testing when I hooked the wrong battery up to them, which ultimately lead to all 4 6030 leds blowing in a split second. But there's a moral in this story: Dont play with lipos when you're over tired

So Im working on version 2 which will sport 8 leds now to light up my bling aluminium parts when I get them.

ValiantGLX,

Very nice! Which wheels are you using? Also - is that a voltage display?

Thanks

The wheels are from a stock losi 1:24 truggy along with the wing

The display shows the voltage of the battery in real time, so I dont need to time my runs any more. Think of it as a digital fuel gauge. It weighs a meer 6g and only cost 2 bux from HK
