Going to the field for maiden soon and got to thinking I have a 3S 2500 25C Polyquest so pulled it out and installed it on the plane. Brought the weight down to 30.8oz which will give me 135W/lb. Now that is awesome power! Will try both batteries on the maiden. Jackie is going to do her best to try to get a video. We'll see how it goes.

Well got to the field and wind was up to 12mph and gusting like crazy but I decided to maiden anyway. Put on the 3S 3300 and took her up. Decided after the flight The 6 degrees thrust correction was excessive so before flying with the 3S 2500 added a couple washers. Landings were not great because of the gusts but managed to bring it home in one piece anyway. Love that 5/32" LG! Really would like to get a decent maiden day for a change so I can trim a plane out properly. Talked Jackie into shooting the video and it's at:

Comments welcome.

BTW if there is any interest I will do load tests to determine camera carrying ability by adding 8 oz of weight to the 3S 3300 version if there is enough flyers interested. Let me know........

Thanks Jackie! Another good video. That maiden looked a little rough with all the wind but the stick held together nicely and seemed to have no problem dealing with the wind. I'd like to see some landings and the steerable tail wheel working in calmer winds. How does it taxi? Are you going to try and send a camera up on this one? It seems like it's perfectly suited for it.
Thanks again Jackie and Boomer!

I taxied the plane back to me after both landings and the tail wheel makes it a piece of cake. This is the 2nd plane I have used this tail wheel mod on. Highly recommended. I have aerials of all the places I wanted so doubt I will fit a camera to this one. In fact in the hangar sell off recently I sold my AP plane and camera to a flyer over by Bend and he is shooting aerials all over the place. Later if I'm up to it I may take another crack at a Slow Stick Triplane using 3 of the Blue Wonder Motors for power. In the meantime I'm waiting for my 59" wing span Golden/Tawney Eagle to be shipped from Taiwan as I intend to mod it with a Sail Plane type LG.

OK short Video of the Flight test of the Mean Machine with additional 8.1oz additional weight. AUW for flight was 41.9oz. Note the climbout is still almost vertical and it still will slow down well. What do you think?

Extra weight of 8.1oz was an old TX NiMH battery pack. Here's how I mounted it.

OK we have entered the fine tuning stage. Motor was barely warm with the 10 X 5 APC E prop so got out the Power Meter and tried a 10 X 4.7 APC SF prop. WOW! Looks like that's the sweet spot. 295W @ 27A which is within MGF specs. That computes to 142W/lb with the 3S 3300, 153W/lb with the 3S 2500 (above 150W/lb wings are considered unnecessary ), and with the simulated camera weight we are still at 112.5W/lb which is still good vertical. Extended static tests and motor was still just warm.
The 10 X 4.7 is also better matched to the SS anyway so thrust increased greatly.

I just finished my AP stick with lots of the mods based on Boomer's posted in this thread. Thanks Boomer, here is mine:
http://www.wattflyer.com/forums/showthread.php?t=40437

It's a bit weighty coming in at 35 oz including the camera and mount. I am using a 2410-09 motor with an 11x4.7 GWS SF prop. It gets up there and does the job but it does it in slo-motion. I can't quite perfect the right amount of down and right thrust as it's still dropping the nose when I cut the throttle. I'm going to try some other motors for more get-up-n-go including the one used by Boomer here in this thread. Thanks Boomer!
