Does anyone have images of thier Hacker A50 16L V2 install in a Wind S 110E? It seems like it's shorter than the V1 of the motor and the stock backing and the bearing fall almost 1 cm short.

anyone running this motor with out the support on the back?

Love to see some images if you guys have them out there.

Here are some images of the motor. Do i need to build a backing for this version of the motor?

If you have the bearing for the rear support it should be fairly simple to cut the support and move it forward a bit. I personally would not run it without the rear support.

awesome, thanks for the advice, starting the mod now.

Or to NOTcut the support, and instead, cut and size a spacer that will hold the bearing that slips over the motor drive shaft.That is the approach I would take (I find that to be easier than shifting the support location) since it is already well-engineered.

good advice, but no i can't get the prop adapter off, it would be easy if the motor wasn't in the fuselage. Any tips?

Hi,

To get the prop adapter off You need something like this:

Maybe for example the Hacker reseller http://www.aero-model.comon Your side of the Atlantic have it.

Nothing a pair of vice grips and a few small taps witha hammer didn't fix.

OK, mod is all done, used the other prop adapter, dremel and some balsa. Love any input.

I say skip the rear support. I fly without it, had motor troubles with the support in. Did a small poll in the pattern forum, not terribly definitive but my conclusion is the rear support causes more problems than it's worth (there have been more than the fair share of motor failures in this plane). Bearing adds resistance/friction, and rear support introduces increased side loads on the motor, if it's actually preventing it from flexing. The motor plate in the plane is fairly robust and I don't see any issue with running without the rear plate.

I had screws coming loose that held the rear plate in. Tried gluing the threads, still losing screws. This tells me there was unnecessary vibration, and sure enough when the motor failed, it was accompanied by a flapping sound, and the rear support had broken apart.

Just my own personal thoughts, take them for what they are worth.

Sorry, didn't see your last post before I wrote this - still think it's unnecessary weight and friction, but I hope I'm wrong and it works well for you

My rear support came loose in flight and the vibration nearly shook the nose of the plane off. I caught it in time and only did minor damage. I now have a carbon fiber rear support and I also installed blind nuts, use lock washers and blue lock-tight to hold everything in place. I have about 60 flights with that set up, and everything is staying put. So in my experience, I need the rear support. Also make sure you balance your prop, and if you are using the spinner and backplate that came with the plane, check the balance on those as well. My spinner and backplate needed balancing.

Rix,

I just had the same thing happen to my Wind 110. However, when my rear motor support came loose it did break the nose. Did you have any damage to the motor and front firewall?

I don't mean to sound like an ass here (the donkey kind not the other) but if yours in anything like mine, and the support came loose in flight it'd be much the same as having a propeller spin around internally in the fuselage, i.e. CARNAGE.

I took my one off after a few issues, was solid as a rock until I had to hand my ESC back to castle.

Beam,

No damage to the firewall, motor or structure.

Rix: can you post images of your upgrade?

I had rear support come loose a few times, even after going and reinforcing. Finally it broke, but no damage to the plane itself (although that was the.last flight of that motor!)

Rear support is junk an not needed Imho.

I machined This Bearing back plate is lighter than the prop adapter installed on the rear.

That is a nice piece! do you or anybody else sell this?
