Help with STRYKER motor mount.....

Hello,

Dont mean to hijack the thread but can use some help from the experts....I am on my 4th motor mount on my stock Stryker C. Im flying along and ...bang...the mount cracks or the plastic mounting ears break away from the motor. Is there a stronger version of the stock motor mount out there? Maybe out of aluminum? If you have any advice or info, can you please post.

Thanks,
Ken

There is a custon mount available from a link in one of the posts , im pretty sure it will follow. Personally i "glassed" my mount with super glue and fibre glass and its solid as a rock ., the custom mount will probably be more reliable but i have had no problems so far even if used as a stop gap or spare.

You need to balance your prop
or
Your shaft is bent

The stock motor mount will take 1500 watts easy if your prop is balanced and your shaft and adapter isnt out of round. The screws need to be 2 finger snug (not tight) and also you need to use Loctite on all 4 screws.

Gary @ Custom RC Parts has a bulletproof mount fo rthe Stryker. It can take whatever you decide to bolt up to it

It sounds nice and loud but I never saw your plane in the video. I will try it on 4s, it was the turnigy 2836 2350k, right?

For those running the custom r/c mount, are you getting this nasty down angle???

I haven't tried it yet but it doesn't look good.

what seems to be the best motor for the dollar out there right now for a 3s-4s setup to put the plane at around 100+ mph

Johnny,

That looks about right to me. You should see a thrust angle about 1-1.5 greater than the stock mount. That thrust angle was developed over many flights and many different test angles.

The benefit of this angle is that the flaperons are kept out of the jet stream while maintaining level flight. Lesser thrust angles required the flaperons to level the plane out.

If you took a close look at it and it looks good to you, I'm good with that. Just not used to it. There is no angle in the stock mount.

Johnny..........
any way for you to take a few different pictures of your mount from all different angles ???

Best to get a few pics with the motor viewed from the top and the side (like you did), but also include the nose in the picture so we can draw a line

In your picture, it looks like you are missing the upper 2 halves of the mount ??????

Here's a picture of a mount on a new build I'm working on. The upper brackets are nearly level and you can see the thrust angle relative to the level. Without the level as a reference, the angle and look very different.
Hope this helps!

Johnny-

After hearing them custom mounts been tested 100's of times I find it hard to believe that anyone could fly with a thrust angle like that...it looks way way off...
