There's one of those fatter pins to push the tappet plate on the sector gear, but it's still not as much as a delayer chip. I like the way it all stays in place when you take the right half of the shell off, but the shimming seems inadequate to prevent an 11.1V LiPo from shredding the gears, steel or no. No mention of anything funky about the cutoff lever, so, without a mechanical fix, you'd have to use an AB MOSFET to get semi-auto to work.
11.1V LiPo OOTB my arse.
