The next batch of Sukhois will be a large one, there should be plenty.

I actually sell both now, and I'd have to say that it's a toss up. The TOC is easier to set up, mount, hook up linkages, the muffler fits better in most planes. It is very reliable and easy to start and has an excellent track record now. The angled front face ofthe muffler allows it to fit into cowls with sloped front like Extra and Edge more easily.

The DL-50 is much newer to me, but is familiar since it's nearly identical to a DA-50. It's more of a juggling act to get it mounted, and a little harder to work with the rear mounted carb. But it seems to also be very reliable and makes a little more power than the TOC.

It depends on what is important to you. They are both good engines. Of course they are Chinese manufacture, the DA-50 is built and supported here, that's what you get for the extra $$$.

OBTW, I heard from DA that they will be able to provide stainless steel canister headers for the TOC-53. This is great news, I should have them in to sell when the new batch of Honda Sukhois come in January.
