@Snoopy1,One question did you not buy the 3W for this plane or did you have something else in mind.
Some may not agree with me, but I have made up my mind. My Yak will fly with the DA-100. My flying Buddy told me today that he will get it set up on his test stand and run a few tanks of fuel through it if we ever get a break in the hot weather. It's like I said before, it is the engine I should have bought in the first place for ease of installation, if nothing else. Not only will it save me time by not having to work on the firewall, it will save me the time in making adjustments to the cow for the different exhaust outlet locations. I have no doubt the DA will fly the plane, not with the same authority as my 3W, but it will be fine for the way I fly.Had the difficulties you are working your way through, this is what I did to my Yak to get the engine to fit and everything to line up. You can do this several ways. If have any questions please ask.
@Snoopy1,
Good question, the answer is ummmm, . . . . . . . . . . . . . . . . . . . .. . . . . . yes. Seriously though, I did buy the engine for the Yak, all the while knowing the red head will be capable of flying any 35% airframe I'd want in the future.

Unfortunately, it is going to be too hot to even work on my Yak this weekend. There are still a few things I need to do while I wait for the engine, but mother nature won't cooperate with me.
Thanks for everyone's input, I really do appreciate it. . . . . . .
The DA 100 will serve you well brother. Super smooth, easy starting, and reliable as they come. And honestly, unless you’re Jace the Ace, no real need for crazy power.
Sorry @dhal22,I'll take that 3W since the DA100's are plenty.
Looking at the linkage the clevis and the horn on the elevator does the pin go all the way through the horn and the clevis so that clevis pin is properly locked in on both clevis arms. Looking at I do not think the pin is fully in gaged, make sure it is. If not it will be short flight if that pin is not fully in gaged on the elevator.Sorry @dhal22,
But I'll give up my MK Aurora kit and NIB Hanno before I even think about giving up my red headed beast. . . . . . .
Even though the staggering temps the last few weeks have kept me from the flying field, I decided to try a little work on my Yak. I got up early Sunday morning and went to the shop. I don't have A/C in my shop, but it is in the shade and I had the double doors open with a nice breeze blowing. In a matter of about a half hour, I was soaked from head to toe so I closed up shop after about an hour and a half and went back in the house. I managed to get the two elevator servos in along with both servos in the right wing. I didn't get any pictures of the wing, but I have a couple of the elevator.

The above picture is with the linkage that came with the plane, but I'm considering changing the pushrod to a turnbuckle for ease of making adjustments. The second picture is full elevator throw

I know it doesn't look like allot of throw from the angle of the picture, but it's more elevator that I'll ever need. . . . . . We're supposed to be getting a break in the temperatures tomorrow, continuing for a couple of weeks so I am planning on getting some more work done on my Yak in the evenings this week and hopefully some more work next weekend. My flying Buddy said he will more than likely re-break-in the DA-100 this weekend as well. If that happens, I might have my Yak ready to fly in a few weeks, good Lord willing. . . . . .
I also just noticed when I posted the second picture that if I decide to keep the linkage, I need to move the nut to the clevis end of the shaft on this elevator. . . . .
Good eyes @Snoopy1. . . . . . . As a matter of fact, the pin was not all the way in the clevis when I took those pictures, but I can assure you that the pin is all the way through and the retainer clip on the other side is locked in place. I learned my lesson with this type of clevis when I lost my Hanger 9 Miss America with a YS-91 on its maiden flight because I did not have the clevis on the clevis secured properly.Looking at the linkage the clevis and the horn on the elevator does the pin go all the way through the horn and the clevis so that clevis pin is properly locked in on both clevis arms.
