The Flow need a receiver battery.
Yes, it need a receiver battery ... all pictures of 1/12 cars you can surely see a receiver battery. Futhermore the text for the update-kit for the SXX speed-controls on the website clearly says, you need a receiver battery for it.
The text for the SXX v2 models on the website says twin-BEC and that they can boost 1s up. The upgrade-kit says BEC and that you need a receiver battery. The new FLOW also (only) says BEC, and this indicates, that the upgrade-kit and the FLOW's are based on the same architrecture ... and therefore the FLOW's also need the receiverbattery.
I and several others in Denmark have used the SXX v2 since they came out without any issues at all ... they have worked flawlessly at any time.
One of the reason that we have chosen the SXX v2 over other manufactures are the ease of use and the performance. When LRP now chose to remove the twin-BEC, we see it as a step back in the ease of use. We surely have prefered, that LRP have had chosed to develop the twin-BEC so it would became bulletproof in terms of reliability.
Several others top level manufactures have integrated step-up volt from 3.7 to 6.0 volt in their speed controls with succes, and wich therefore will be easier to use in terms of not to use a receicerbattery. But theres have not the the easy programming system that LRP have, and we all love so much.
The choise of speed control for the upcoming season has becaome a bit more difficult - the easy programming or no receiver battery? - hope much LRP will continue the development of a twin-BEC, and incorporate it in the next generation of the FLOW's - then the coise will became easy again
Best wishes; Jens

Ronald did have a Rx pack in his car, it was just not plain to see. All LRP racers used one at the WCs.
