Can't get enough

Well I posted pics, included info, and no help...I guess I will have to add weight to my right wing. I can't believe I am the only one with this problem of the left bank tendency. Wish I could find a solution.

Maybe thrust angle of engine got knocked outta wack? One aileron higher than other or not hinged right? put it on your finger center of fuse see if it tips to on side or other.( kinda like checking cg) Make sure rudders are centered?

Other than that don't know what to say.

The pics were quite small, hard to see any problems that might be there...in the last pic, is the plane sitting perfectly level? One simple thing you might have already checked, are the wings nice and straight and level? I.e. no warping or twisting, or one wing being higher than the other? With these little planes, it doesnt take much to cause big problems. Kaw1000 has some good suggestions as well.

So you're into private videos, eh?

Basically, a bird that was interested by my Stryker, and two failed upright boomerang that ended on the ground. Don't worry, I normally bail out early, those are the exceptions. I was trying, and trying, and trying, and not watching how fast the ground was coming toward my airplane . But yes, I'm now better at upright boomerang (still end up inverted too often, but hey, winter is not here yet...) . No damage on the Stryker so far.

There is no warping, and they are straight. When I do the cg test it sits straight and true. My ail are centered. I don't know, but thanks for the suggestions. It could be an offset rudder.

Got my maiden flight of the UM Stryker in this morning. All I can say is WOW, what a great plane. Only flew one pack through but was pretty easy to get on to coming from the Beast only a week ago. It certainly is fast and twitchy even on low rates which is all I tried so far. Bit nose heavy that I had to trim out for now, will have to cut out some foam to get battery back it seems forr proper CG. And I LOVE parachute landings, one of the best things about this plane I think, and that was even with the low rate settings, on high it should drop in even more vertical.

Only issue I ran into was a broken nose. Did what appeared to be a fairly soft slightly nose in landing into soft wet grass and the nose cone popped but also broke part of the foam. Nothing major but I think that pin the rubber attaches to does more harm than good as it looks like the pin itself did the damage putting the force into the foam.

I wonder if it would be better with the pin removed and the rubber nose attached with CA directly to the foam instead? Or maybe reducing the length of the pin to a 1/4" or less, so it doesn't extend so far as all it needs to do is hold the rubber. Even velcro might be better. Would reduce the nose weight as well as possibly prevent the issue I had. Anyone try this or a similar mod?



Maiden video to follow...

Oooops, I put it private while it was uploading, then I modify it to public when it's finished... I guess it took a while for Youtube to receive the modification... Sorry! As I said, not a great video anyway, since the %?$&$% camera was dying on me, so that's why I was low profile!

You're probably the first who would attempt such a mod... Sure enough, if you could weight that pin for us (if you decide to stick the nose directly), that would be great... Because if it's heavy, it would definitively be a decent mod for those with nose heavy Stryker... Probably hard to remove though, looked like it was stuck very well.

It is pretty light so not sure if my scale will weight it or not. It wasn't as hard to remove as I would have liked

I think for short term I will just CA it back in as is, but if it happens again I think I'll remove it and go with velcro, like a small circle in the middle.

Nothing too exciting flying wise. Maiden flight of my new Stryker...

Is there any way to fix compressed foam on these UMs? I know with EPO you can use hot water to expand it back, any way to do it on these or bascially it is what it is and just live with it or fill it?

Would like to fix my nose compression if I can before I CA piece back in. It isn't compressed very much but would like to get it back if there is a way.

Well if some of you have used a 4x4 I think I better give it a try. Hopefully that will speed it up enough for me to enjoy flying it instead of cussing it for being to slow.

Parallel Charging


My thanks also for all the parallel charging info. That cleared things up a lot. This electrical stuff confuses us civil engineers

The hot water trick will work. It has been done on the Sbach (by me and others).

I can tell you it works as I essentially busted the whole front half of my Sbach off and after water and epoxy it is back to flying as new!

Great thanks, I'll give it a try.
