Extreme Flight E Yak vs Extra

[Stainless Skills]

Should I buy any new hardware for the servo's like small ball links or new servo arms? Would they aid in the smoothness of control or are all the stock linkages fine?

I ordered that KOOLFLIGHT Micro UBEC, it looked very nice and much more sturdy than that other one.

What kind of prop should I start out with and where can I get a spinner that would fit the motor easily?

I have never understood why you would use a larger prop with a 3 cell and a smaller 12'' prop with a 4 cell. Or is this just becaus ea larger prop would place more of a load on the motor and esc with a 4 cell battery? It would seem like a 4 cell would have the extra power to swing a larger prop.

Has anyone ever baffled the cowl or blocked off part of it with some balsa sheeting.

I think I am going to spray paint the whole motor box assembly a dark metallic blue along with the inside of the cowl. I might even try to use some thick CA and make two flat walls on the top and bottom of the airscoops with balsa sheeting. I might try and paint these to look like the real thing, it sounds easy enough, is this a good idea?

The tail wheel looks sort of weak to me, I dont know if it is or not but I have had many bad experiences with weak tailwheels on just about all of my planes and is there are stronger one that any of you use?

Smaller prop for the the larger cell count. You want to prop up the 3cell to get maximum rated amps from the power system. That goes for all setups , the 4s just needs less prop to do that.

THe tail wheel on the Yak needs an update if you are flying off a rough surface.

Use a pin hinge with the tail wheel wire as the hinge pin, 90deg bend forward into the fuse. That way all the force is on the fuse, not the rudder and it's bottom CA hinge. Again, only neccesary on rough grass fields that might "grab" the wheel in a gopher hole and tear the rudder off.

There was no issues at all with the Extra's flying capability, only the setups by the people who built them, IMO. Mine , built stock first, with a hobby shop audience no less, was well documented , and I pulled no punches when writing about it, and was grilled like a shrimp on the barbie by the "kangaroo fan court".

However, many peeps had the same issues, and with good modeling skills, a little help from the helpful people here and elsewhere , those issues are non-exsistent for those that are willing to read about something before they build. Just like we are doing here, with a lot less mishaps.

The Yak is great, and I am going to need more batteries. More batteries, more batteries.

Anyone try the Polyquest 2150 4s from Hobby lobby??? I wonder if it really is a bargain, or if it will fall on it's face when pushed??

Its a Yak, skip the spinner It's just weight that is not needed. Skip all the other stuff too, Weight adds up quick on a small electric model!!

The tailwheel (if it's the same setup as the extra) is a little iffy though. I never had any trouble but I can see how it could be rough on the rudder hinges.

Here Stainless. This is my build thread on the Yak. Scan the first 10 pages. It will tell you everything you need to know.

great, that is just what I needed. I dont really want a spinner either.

I was also looknig at the Polyquest 2150 4s. It is something like $80 or $88 and that is alot cheaper than the other batteries, would it be a good idea to get this one or are the cells made by a different manufacturer that might not be as reputable.

Also, on my extra i used 2-56 ball links and made up a elevator pushrod because the stock setup had a little slop. I also used Spiderwire 30lb test braided fishing line for the pull-pull. Lighter and easier to work with than the included steel cable. I used the stock hardware on the wings.

I would love to know about the Polyquest 4s 2150,s. But even my LHS doesn't want to bother with Hobby-Lobby, as they have killed him with sales after he stocks up at full price.

If someone has one of these please post some numbers. My quess would be it would pale in comparison to the EVO's and TP's. You get what you pay for.

That LHS is not alone.

[bodywerks]

Ditto! They haven't earned the name "Hobby Monopoly" for nothing! I try my best not to order anything from them...and have done a pretty good job of it!

Sorry, didn't want to start bashing HL, this is about the Yak.

Anyone see QQ's 49" Yak?? Sheesh, there are more Yaks now than anytihng, I quess that is how it was wit hEdge's and Extra's and before that Caps. But, man, theey are everywhere in every form.

I am trying to do the fixed thrott setup Freddy, with the CC45. I want to see if the resolution gets better, and I can't believe it, this airframe makes you want to fine tune it, every bit as much as a big bird.

If I could only keep the wheel pants from geting trashed. Damn, I love those spats, but alas, the deer make big , big holes in the turf.

Personally, I like the throttle resolution better on the Extreme Flight controller more, but the CC 45 does the job. I agree with making the airframe perform as well as possible. These little arf's are getting better. They are my flight simulator.

I here ya! One of my spats are trash.

You like the Airboss more , huh? I can snare one to try, I only went with the CC b/c it was part of deal with a friend. He managed to burn his AB45 , he is/was new to E-planes.

It's funny how bad rumors spread though, the LHS ran out of cc45's and there is a stack of AB45's just sitting under glass. I'm game, I'll throw one in and try it. My AB35 in my 300e never hiccupped.
