I bought my 55-CS from Cactus Aviation. If I had to do it again, I'd defintately go to Aircraft International. I don't want to trash anybody on this thread.. I can only say do your homework on this and other sites before you put your money down!
I've had a dozen or so flights with the 55... a much stronger motor than the DA-50 that I had in it originally. With the rear carb, there was enough weight behind the original motor that I didn't have to adjust the balance a bit, it flies perfectly. You do have to cut a larger hole in the firewall to accomodate the motor, but Aeroworks provides a no-brainer template to cut out the firewall. I had a little trouble because I already had servos mounted for the throttle and choke, but nothing real major.
I guess folks usually measure motor performance in terms of "unlimited vertical" or "pulling out of a hover".... the DA-50 had neither. It flew it just fine, but if vertical is your thing, you won't get it. I had a 22x8 on the DA... went to a 22x10 with the 3W (even for break-in) and its a marked improvement over the DA. I'm not a hovering kind of flyer, but it will go vertical as long as you care to. Once it gets broken, I'll switch to a 22x12... 50% more pitch than the old motor, and folks say that the motor flies it great.... we'll see.
I also purchased a used 3W 50CS that I was going to use on a CompARF 50cc Yak. I decided to go with a canister muffler on this plane, and it wouldn't be a great fit with the 3W... CompARF sells a custom bent header for the DA-50, so I opted to buy a new motor, header and canister.
Consequently, I have a used 3W 50CS for sale.... I haven't run it, but it looks in good condition. The seller said it had about 4 gallons through it. I paid $525 for the motor, spinner and pitts muffler..... I'd sell it for the same amount. The 55-CS sells for $715, another $120 or so for the muffler and probably $50 for the spinnner... total of almost $900. So, if you want to save almost $400, give up 5cc from the 55 and get about an extra horse of power from the DA-50... send me a PM. I can send pics. I'll be traveling this week, but home for the weekend.
