I am using the Intellect 5400MAH 4s lipo
http://cgi.ebay.co.uk/Intellect-Lipo...item3cb6129a3c and they last me 12 mins full bore or 20 mins + if i take it steady
.
I have been using the Orion 6900MAH 4s lipo and that will last me 30 mins + but it cost £190
. Brilliant lipo, best lipo i have ever tryed
. I am running a standard losi 8ight 2.0 with the Xcelorin speedo and 2100kv motor.
Hope that helps
Chris
