1/12 forum
Put the receiver, the cap, the transponder and anything else you can on the side the servo is offset towards, usually the right side. Put the ESC and the end of the of the battery with the contacts on the other side. By moving things in toward the center, or out toward the edge of the chassis, you should be able to get pretty close. Mine was within 3 grams, which I think is close enough.
Hi guys, I'm going to start running some 12th scale on a new indoor asphalt track opening in the area and am looking for advice on 1s speedos, will most likely be running stock. Was looking at the Orion and the hobby wings??
Thanks,

In the same ballpark in price, and have been impressed by them (working on getting a few myself) maybe add the ORCA to your list.
Well, seeing as I've been name checked I thought I'd better chime in!
The A5040 is slightly larger than the Sanwa, but the chassis of the R12C is slotted so it does bolt in fine. The output spline is around 5mm off of a 'normal' servo centre, so it wouldn't really be suitable to mount up in the front of the car in the traditional location, it's the bellcrank that allows it to be used.
Since the spline sits slightly further forward in the car than it would with other servos it's necessary to either cut down the turnbuckle between the servo saver and the bellcrank or use a slightly shorter one. I use a 25mm Hot Bodies one and that's perfect for the job.

The Sanwa SRG-HR is definitely worth tracking down. Here's a good place to order them from: http://www.modele.sklep.pl/en/Katalo...WO-SRG-HR.html

I've been running the Viper and the Orca...both are great ESCs so you can't go wrong with either. Tekin has said they are working on a 1s version of their new RS2 which sounds interesting...but no word yet on when they will be out.
I really like the Hobby Wings. Reasonable prices, reliable, awesome performance. I have 2 of the older 1s speedos. I would love to get some new 1s v3.1's if I need to replace them someday.
The v3.1 having everything (booster and power cap) in the case is WONDERFUL!
