Some of the newer UM craft are a bit much for the old 180mah 15C cells. I specced out these cells 2 years ago when we had the Cessna and the Edge. The 25C Hyps were certainly a better cell and as you'd expect would live longer with the higher loads of the newer planes.
My problems were with the MA 180's and older Horizon Micros,,, P-51, 4 site, Sukoi, MSR, etc.

Sorry... my bad... OK... so on page 9 of the instructions it gives instructions to reverse the elevator. But instead you need to reverse the Aileron. No plug re-switching involved.

It's all good figured it out but kind of did it old shool. Found out what lead went to what servo and so on. Horizon put out a bulliten on it. http://www.horizonhobby.com/ProdInfo...dum_083111.pdf

4 possibilities:

1- Because that's the one the design engineer had on his desk when they put the first prototype together!

2- Because somebody made a mistake when they did the Bill Of Material for the assembly line, and got the wrong part number. Once ordered, they went ahead with that part.

3- They wanted to make it a bit harder on us to get third party batteries, though we all know that it won't work.

4- They looked at lots of connectors, and found out that only that one could carry the current, was light enough, easy to use, allow for balancing, and had the minimum number of insertions high enough to meet their need. (I was kidding about option 1 to 3... Option 4 is probably (or hopefully) the real reason )

Well I have knocked the nose off the stryker 4 times now. I just glue it back on...but man, it really is a weak point. I don't think I can land it any slower. I don't know how to do the pancake landing.

With the battery forward you will need some wind to pancake land

mine lands fine, just flare it at the last second.

Are you using full rates? If not, that's your problem! Because otherwise, it's only a question of going full elevators. Just kill the throttle while you're about 20ft in the air, let it slow down and progressively add elevator to keep the nose slightly up. Basically, you'll loose forward momentum, and slowly end up with full elevator, and the Stryker will elevator land itself. Once you get use to it, next step is to learn how to do the cobra (kill any speed quickly). Basically, even if you go fast, you can stop the plane on a dime, with a full elevator (doing a full nose up, ie, a cobra), then, level the plane and do an elevator landing.

I believe I came across it in this thread somewhere, but can't find it now...

So If someone could answer or point me in the right direction...

When using the DX8 with the UM Stryker what DR's are being used
to NOT overthrow the linear servos? when at full rates....

Maidened my new stryker this morning after figuring out the dx6i programming. removed the front wheel and put the battery all the way back. Only took a few clicks of elevator and aileron trim. Fun plane, high rates are crazy..kept it on low. Now I need more batteries.

My Ultra-Micro F-27Q is HORRIBLY NOSE HEAVY!

With stock battery all the way to the rear it needs so much up elevator to stay level at 1/2 throttle that giving it full throttle puts it into an immediate loop without giving corresponding down elevator. Not fun to fly at all this way...

Why does Horizon keep making this mistake!

It's the original UM Sukhoi all over again...

Did any of you completely remove the foam block in the rear of the battery slot and place the battery all the way back to the receiver?

I was hoping that cutting out the foam block won't weaken the structural integrity of the plane???

What elese can be done to lower a terribly forward COG in it's stock form!

That's seem like a lot, but who knows... Manufacturing at it's best! You can tape a little bit of weight way at the back, on the plastic part / motor mount... Had to do that since I added some glue and carbon fiber on the nose of my Stryker after a bad crash and I wanted perfect balance. Didn't change anything about how it fly... Still fly awesomely!

You can glue small brads in the trays under the rudders. That's the most rearward position available and that combined with cutting foam so the battery could be moved back did it for mine.
