I have finally been able to finish two of our Assasins, I have flown mine and soon my young bloke will maiden his, here is a couple of pics. They have lights fitted and the invasion stripes on my sons are a glow in the dark strip.

A different Prop saver

Yea that's a little different saver than most but it looks like it will work fine.
Push the unit up against the motor housing and cut the unused portion off. Keeping it up against the motor housing will reduce bending the shaft.
Good luck.

I thought the shaft was hardened steel? Wouldn't cutting the shaft be fairly difficult?

Should you bend the shaft or lose the retainer clip you can get replacement parts for the 2812 from these guys.

Bearings, clips and the shaft all here.
When you cut the shaft leave a 1/4" or so beyond the prop saver, on some props the shaft will poke through and help keep the prop centered.
Good luck.
Actually the shaft shouldn't go beyond the saver by 1/16" or so, you don't need much.

Lee, have you ever made any center extentions for the Assassin? Would it be possible? I was thinking 4".

Me too, simple like that. A very cheap prop saver will solve any problem.

I will occasionally will break a bolt trying to tighten them but they hold as good as the more expensive ones I have bought.

And rem to protect your motor from metal grinding dust when cutting the shaft ...... I always use a latex glove ...... put a pin prick in it and the feed/stretch the hole over the shaft and cover completely the motor.....

I measured the shaft (FC2812) and it sticks out ~17mm from bell.
Thanks guys that's my problem....I bought a 3mm collect prop adapter - I need a prop saver insted.

Man, you're dialed into what's happening in Alaska! Yeah, Anchorage is expecting 100mph gusts up in the hills. I'm hearing that they're probably going to shut down the airport there too, which makes sense. Here in Dillingham we've been up over 40 for most of the day with gusts hitting 50 or so. Since Saturday night it's been rain and wind. No power outages except for one on Sunday where it blew to roof off of some guys house and it landed in the power lines. That shut off power for a couple of hours for some folks but I've been lucky so far. Passed a house fire on the way home tonight. Not sure what caused it but they're talking about a blown over smoke stack or something.

It's getting dark now so falling trees are becoming a danger. I spotted some that had fallen over across the street but so far the ones around my home are standing tall and weathering it. Could be a long night though.

Ok here comes the big experiment.
My buddy Jim and I have the same Assassins and electrics but his is always noticeably faster. I've tried a new motor and a different ESC with no improvement. I've tried his prop, no change. He claims it's his Thunder Power G6 25c batteries vs my Nano Tech 40c. I just ordered some, let's see if the nearly 3x more costly batteries make the difference! We were going to try his in my wing but he uses JST connectors and I use EC3's and we didn't have an adapter.
My setup is consistently pulling 10A at 115W static WOT.

That's interesting!!! I think last time I checked I was pulling over 16 amps with the 2812-1534kv and a 3S 1300 Nanotec Lipo and a Hobby King 25-30A ESC. I am using Micro Deans 4 pin plugs cut down to 3 pins for the connection from the ESC to the battery.

How about weight on both wings? Not saying that's the issue, it's just an interesting scenario, and I'm curious about all the data

I don't think it is a weight issue because I have watched and videod both wings flying together and you can hear that Jim's wing even sounds more powerful. It definately is faster and gets vertical with a lot more authority.
