Nothing wrong with trying to interpret the rules by to the letter but also common sense sometimes needs to be considered. As said above, when you plug a life direct to your receiver, it is then also directly plugged into the esc.
Now lets consider people who use a Lipo receiver battery and a regulator. Then the battery is not directly plugged into the receiver. Would you DQ someone doing that if teching an event? All the BD is doing is giving you a regulator built into the esc. What about people running boosters? no battery being plugged directly to receiver then. You saying this isn't legal?
I believe the rules mean nothing unless someone with proper knowledge who can use discretion and good judgment can interpret them. Even F1 can't release rule that aren't open to interpretation.
You could probably continue this for another 3 pages but it is no longer helping people who read this thread increase their knowledge of 1/12th scale racing. Time to let officials from ROAR, EFRA and even our little AARCMCC decide whether we can use our BD's or not. At least till now its been considered ok.

I just want someone to give me $50 to learn the hard way!
One thing the Tekin does have going for it is its size. I have got to admit that the smaller foot print gives you more flexability in where it goes, although pretty much everyone runs the same setup (regardless of ESC) anyway.
On the topic of regulators and the BD's BEC connection... Both of these allow the use of a 7.4 volt lipo which should in theory allow far more options for Rx packs. However I have had very little success finding small lipo packs for this use. SMC had one that was very close to perfect but still a little big. Anyone else managed to find something nice?

Epic has one also, 220mah Li-Fe with a switch. The way it is wired it is very easy to shorten the wires and retain the switch. I'm using the Custom Electronics crimper and pins/sockets for the receiver end.

The full version of the AARCMCC rule 3.1.7 is:
"A receiver battery pack must only supply power to radio receivers for its operation and the control only of addition equipment listed: speed controls, servos and transponders for their operation. No other devices will be powered from a receiver pack."
This can be interpreted in different ways. Nowhere does it say that the Rx pack can only be plugged into the Rx. It does say it "must only supply power to radio receivers" but does not say that it can't be via anything else. If it is interpreted in the way that would make the BD illegal it would also make voltage regulators illegal! (Reading it again voltage regulators may be illegal whatever way it is read as they are powered from the Rx pack.)
To me this is a badly written rule that can be interpreted too many different ways i.e. more than one. The BD could be legal or not legal depending on how this rule is read. And of course the wording of the rule is not your fault but you could approach your organisation and ask for clarification of the rule.
From what I have read of the ROAR and BRCA rules (I won't list them here) there is no problem with the legality of the BD.
I'll keep on using my Tekin in my 12th, and be happy for my friends to use their BDs.

And this is a 12th thread, so lets stop debating the merits of miniature LiPo packs and get back on topic!!

Doubt it, i know of two other rules which dont get enforced in 12th scale in australia. One of those is completely trivial (and should be removed) the other is pretty big rule which is overlooked.
But it peeves me off when they dont change/enforce the rules. You try to do the right thing but everyone ignores it so you kind of end up being the only person getting penalised (if you worry about that kind of thing).

Hey Sydney racers, I am on my way for a visit (this time for real!) Where are you currently racing at? If time permits, I would like to swing by. Should be there Aug 23-25 which is mid week. Not ideal, but you never know.

Aug 25 is Wednesday here. When time is your flight back? If it allows you could take your 12th for a bash around Windsor on wed afternoon/night as they are open late as a sort of practice night every wed night. It isn't carpet but a painted concrete surface. It is painted with a sandy paint that ups the grip quite a bit of the standard surface, then they have layed down layers of VHT so your shoes stick to it as you walk across it. Dumping a 10.5 1s is not hard with so much grip and it shouldn't be hard to stash your 12th, radio and a battery or two in with your luggage.
