Aeroworks QB 150cc YAK 55M

Still haven't talked to Rocco, Jim, but in his latest video of this plane he's running two servos per aileron, one servo per elevator. But, he's running all Hitec Brushless servos. The ailerons have 9380s on them and the elevators have 9485s on them (I'm guessing because he didn't have any more 9380s, or I would think he would have wanted those on the elevators, as well). More later...

For IMAC only I would only use the 1 1/2" SWB arms on everything but the rudder. I have a few 7950 on another plane that I like. I could scavenge them from that but I'm still flying it. Is there a provision for rudder servos in the tail?

I like the Hi resolution pictures and videos your doing. Looking forward to following this build.

Oh I have the DA 170 and RE3s here now too.

On the Gorilla glue. I really like it. I use the white and it gives at least 45min working time. As long as the humidity is up you don't need any water anywhere and that also helps keep the foaming down.

Okay, well, even though I've seen these water bottle tanks for years and had them in my 3W planes... I never got around to getting a PSP water bottle fuel tank. I tried one in my Sukhoi and it's working great and is 3oz lighter than the included tank. First thing you have to do is get some water from the store and drink it. I put Monkey on that:

Didn't take him long to put the kit together, either. PSP has a video showing you how it's done:

Anyway, Monkey didn't really let the bottle dry out, we'll have to address that:

PSP sends along Viton with the kit for the carb line... seriously good stuff.

Here's how the kit arrives:

Here's what's included:

I'd have to say, Jim, if a guy isn't really prep'd and organized... along with being super fast... 30 minute epoxy on the ailerons hinges, both sides at the same time like the manual shows... is a challenge. For doing the aileron and wing at the same time the 45 minute working time gorilla glue you mentioned sounds good. Even 10-15 minutes of working time would be fine. But, 30 minute epoxy has always given me 3-4 minutes, max. I did the first aileron the way the manual suggests and I would not try that again. haha

The good about doing the hinges yourself:

Hell, four minutes and you're done.

The bad about doing the hinges yourself:

Hell!!!, four minutes and you're done!!!! :O

However much you can get done in four minutes, that's what you're left with. haha I think I'll have a stress free, casual time, doing the hinges with 30 minute epoxy the way I always have. The surfaces first, then after they setup, put them in the plane. Anyway I made a video showing the wing after I glued in the hinges:

Dropping back a second... I did finally get my hands on some Super Lube! haha I've used this stuff for years (don't say it!), and was glad to get some more vs using Vaseline. Using Super Lube just sounds a lot cooler than using Vaseline! I spread a healthy amount over the hinge knuckle and also work it into the hinge pretty good. I know that you know this stuff, Jim, but for the noobs, the reason I do this is to keep any epoxy from sticking to the hinge knuckle.

I've talked about this for years in these reviews, I always recommend bamboo skewers from the store rather than round sticks from a hobby source. The bambbo skewers are like 1/10 of the price!

Looking at the hinge pocket (thanks for the pictures) I see the one thing that scares me most about these hinges. All the exposed balsa for glue to adhere to. Epoxy may be a better choice but does anyone make a 45-60 min epoxy?

If you have not used the gorilla glue I would do a test hinge first to get an idea of what it will do. I usually use painters tape to cover everything I don't want glued together. I use a hole punch to make the hinge hole in the tape first. Then I coat the hinge knuckle with petroleum jelly that has been heated up to liquid form. I also use a small paint brush to coat the area around the hinge holes. Just like with epoxy you do the hing hole first then the hinge. Keep in mind a little glue goes a long way and to much makes clean up a pain. By the time you work your way through one side white foam will start to appear, just keep working it will be easy enough to pick out as long as you prep everything first.

looking at these pictures I see a problem with the way I hinge things. Once everything is together I don't see a way to get the tape out. I guess coating the covering with Vaseline will keep the glue from sticking to it but then there is the pocket. I should clarify that you have about 40-45 minutes total before the Gorilla glue takes a hard set.

Just did a quick google search and only found one 60 minute epoxy:

In the Q&A a guy asks how much working time he'll actually have. One guys says 4 minutes, another guy chimes in and says probably less than that. haha
