Hi Alan! Yeah, sounds like something unique you have going on. I wonder if this other site would help? I have it posted over there, too, with some pics:

Here's a short video I made last weekend, with a "less than perfect" first landing. Not all the decals are on either I've yet to discover all that this plane is capable of. It sure likes to spin, though!

I love watching her "stall in" for a landing. Such a floater. Flies like a big shockie. MM IS the man!

Nice flying buddy!! I would have to agree that the AM looks like a real floater, especially with the little bit of wind you had. Were you trying to fly inverted flat spins? If so it looks like your cg could be pushed back some or maybe increase your 3D rates to get some additional throws. I look forward to seeing your finished review on this one.

Thanks Tim and all,

I promise to get some really decent video for the review. I agree Tim, I plan to move the battery back and increase my high rate throws. I've heard that 125mm is about the CG limit, so I may give that a try. It really amazes me how this 33oz plane slows to a crawl, yet it rolls and snaps like a Mini Funtana. The wing loading is a huge plus.

So what is the Schiznik prop for the Rimfire_35-48-1300kV outrunner on 2170 3S LiPo????

I may run this system...

Motor wires

For those using the Himax motor, be careful how you mount it or you may end up with bare wires that shorted against the outrunner casing like mine. In the attached picture, you can see how the insulation on the wires was worn off (left circle) because it was touching the rotating outrunner which has sharp edges (right circle). To avoid this situation, mount the motor so the wires come out the bottom and tack them to the side (I just used tape). If the wires come out the top, there is very little room and they naturally want to rest on the motor.

The symptoms of this were strange. I would be flying along fine and towards the end of the battery life, the motor would make an odd sound and it would cut off and on momentarily and randomly. When I removed the motor, it worked fine (no shorting then). When I inspected it closer, I saw gray dust in the spinner and knew something was rubbing. That's when I spotted the wires. Fortunately, my CC Phoenix didn't get damaged. I think this is more of a problem for the Himax motor because of the sharp edges on the moving part of the outrunner, but suspect you could eventually see this on other outrunners, too.

Wow! That is amazing how gently it just floats in from watching Ronnie's video. Thanks for putting that up! I'm getting ready to maiden my AM today.

Hi thomer,

Thanks very much! Good luck on the maiden, I hope it is a big success, I know it will be! I hope to finish the AM review next weekend, still waiting on some clear weather for some more video

Thanks Ronnie...just got back from the maiden on the AcroMaster. Woo Hoo! What a sweet ride! My setup is a Torque 2830-1095, Phoenix 35, TP 3s 2100 Prolite, HS-65's for ailerons and HS-81's for rudder and elevator.I had an APC 11x5.5 since I didn't have a 12x6 on hand. I balanced mine at 120mm from the leading edge of the wing. I have had the plane for about a month and a half. It was all done except the little wimpy hot glue gun I used to glue in the servos wasn't hot enough to securely glue the servos to the elapor. Bought a high temp glue gun today and this time it worked great. Those servos aren't going anywhere now.

Did a ground check and found I had the motor reversed. Quick swapping of 2 wires fixed that. All control surfaces were good. Power up! Plane took off within 25 feet and straight up she went! Not ballistic, but plenty of power. I know when I switch to a 12x6, it will be even more spectacular. This plane does NOT feel like a 2 pound+ plane at all! I was amazed at how easy it was to fly and it is a total floater! I had a lot of throw and it was very responsive, actually too much. So I was very gentle and easy on the sticks. I heard someone on Ronnie's video say, "it sure likes to spin" and yes it does! Very fast axial rolls. Very tight loops with lots of elevator throw. I'm still working on 3D moves, and I can tell this plane is going to help me learn them even faster. I was able to hover for a few seconds, and I tried some harriers. Need to dial in some expo because the fingers get real squirrely when trying to fly 3D.

When I first read how "heavy" the AM was, I was a bit hesitant to buy it because I was thinking "it's going to need a lot of speed and it's going to hurt if it comes down." I have a lot of planes in my fleet, and this one has the lightest flying feel of all of them. Very similar feel to my 14 ounce Wing Warrior Straight Edge foamy. Honest.

Flew for about 10 minutes, and circled a few times preparing for landing. I had it at around 1/4 throttle and kept thinking it was going to stall, and it never did. So I tried a dead stick landing, and it glided in like a gentle sailplane. Unbelievable! Battery was barely warm.

It's a keeper, it's a winner, I love it. It's going to be my new "bring to the field everytime" plane. Glad I have a only fits in the bed!

That's great news, man! Sounds like you had the exact same experience I did. I had WAY too much throw(especially high rates) and not enough expo on my maiden flight, but it's set perfectly now. And call me crazy, but as a buddy observed about his, I feel more "connected" to it with the new DX7 system.

Again, congratulations thomer!
