The proposal includes both stick and saddle. It also includes the dimensions that would include Trakpowers Stick and Saddle including both
4400's (dimensions L-70 x W-47 x H-30) and
3200's (dimensions L-71 x W-47 x H-25)

Was the vote raised?
Which way did the vote go?
If (according to what's been posted previously) why was the proposal split between stick and saddle?

Rule 25.1 Proposed: Chris Long Seconded: Jonathan Clark 1.09.2008.

Amend to read
“Cars will be driven by a maximum of six rechargeable Nimh cells or two rechargeable Lithium

Polymer cells in stick or saddle pack configuration, which cannot be replaced after a race has started.

(Rationale To allow the use of Lithium Polymer (Lipo) batteries at 1/10 Off Road Regional and National events in 2009. Many club racers are already using Lipo batteries at club meetings; if Lipo batteries are not allowed to be used at Regional and National meetings a growing number of members will be excluded from racing at these meetings.



Rules to be amended

Electric Board 3.1 – Amend to include “2 cell (2S) Lithium Polymer rechargeable cells rated at 3.7 volts nominal per cell, 2 cells in series, battery packs must have a hard protective casing that completely envelopes the cell(s).

The maximum case sizes are as follows

Stick packs
Length: 139.00mm
Width: 47.00mm
Height: 25.00mm

- Saddle packs -

Length: 71mm

Width: 47mm

Height: 30mm
(Height excludes the mouldings on the bottom of the case that help locate the battery pack in the car)







Electric Board 2.1 – Amend to include “2S Lipo 7.4v rechargeable battery pack - £80.00

BRCA Electric Board 2008 Safety Guidelines and Technical Rules for use of Lithium Polymer (Lipo) Batteries To be adopted by 1/10th Off Road Section and amended to incorporate the above proposed rule amendments. ie rule 1 to be amended to include saddle pack batteries and dimensions.

The BRCA Electric Board Lipo homologation list, to include saddle pack configuration lipo’s once submitted by manufactures and approved by the BRCA.
Because there is already a rule (25.3 I beleive) that says something like, we will only use batteries approved by the Electric Board, it is not possible to have a rule which directly contradicts another rule, therefore the proposal by Long/Clark was unable to be passed.

It is therefore up to the Electric Board to decide what rules they set for dimensions of Lipo and we will have to follow them.
