    Nice in your face flyin'!

    Your's looks so much better than mine , I've got about an ounce and a half of extra glue on mine, right now.
    But, it's all good, my second one is sitting at the LHS waiting for pick up, along with a HiMaxx 2808-1160 to replace my 2808-980.

    I LUV THIS HOBBY!!!

    Ken

    Status: offline     		mine with a 2808 860 Himax on 9x4.7 prop - all JR 241 and one 281 serv0 - one 350 batt - just 9 ozs
    flys as designed - which is to say - a bit differently!
    really fun tho -once you get used to the roll n yaw inputs.
    George really designed a fun to fly setup.
    we put the Park Outrunner on 3 cells (350 ma pack) in a twin model (Guy's) and it is for all practical purposes, the same .

    Status: offline     		I changed from the Axi 2208/34 to a LittleScreamer's De Novo CDRom motor, has well over 14.5 ounces of thrust rated conservatively and weighs 24 grams with cnc machined motor mount. I am shooting for 8-8.5 ounces all up weight. This will give me close to a 2:1 power and should rock for the indoor show.

    I know nothing about the himax setups, but it it is a match for that battery its WAY overkill.

    I flew an e-flite ultimate with a 1100/AXI 2212/34 and it was way way way too much weight.

    The oerfect setup is the one everyone is using, the e-flite 370 and some 8803S pack or another.

    Status: offline     		OK, we had some nice WX so I took the Tensor out for the maiden. This thing feels like no other plane I've flown! If you weren't very good with the rudder ...you will be after flying this. Very cool flying plane. Knife edge loops are comical.....and doing rolling circles with thing is just cheating, because there's no way in hell I can do them with a conventional plane.

    The only thing that I really didn't like is that I was trying some hovering type stuff and the low-voltage cut-off, well..........cut in! Needless to say I was about 5 feet off the ground and it nosed in. The motor was just starting to turn again after I brought the throttle back...it wasn't going that fast. The prop didn't break....but the fuse broke in two! I was kinda pissed. I fixed it with some CA and some carbon tubes.......but I was hoping for a little more durability. I guess I'll just have to keep it higher at the end of my 8 or 9 minutes of flying time.

    BTW, the E-flite 370 outrunner (1080kv), TP 860 3s and CC ph10 really seems to be ideal. You get 8 or 9 minutes and you're at half throttle most of the time.

    Cool package!

    Status: offline     		I've never used that motor before, but they tell me it's got more torque than the 2808, more power, in other words.

    I'm sure someone can correct me, if I'm wrong. The other stuff sounds about right, except you might want to go to a larger battery pack for longer flight times, maybe 830 or 870 mAh. Not a ton of weight difference, double the flight time, or more.

    Status: offline     		I"m still having prop issues. I went with the recommened setup, The 1080 kv outrunner, 860mah 10c constant 15c burst pack(Thunder Power). I have everything set right on my pheonix 10 and heck im using 2 tiny HEs 2003 servos and one Futaba 3108. The problem is i cant reach full throttle without it cutting, I have yet to go get my friends watt thing that plugs into your batter and speed contoller that tells you amps, so im not completely sure at these assumed amps. I want to run a 10 by 4.7 prop, i couldnt, then a 9 by 4.7, and still couldnt, then a 9 by 3.8 prop!!! WHAT THE HECK!!! I thought is wasnt supposed to draw that many amps, people say they are using 10 by 4.7 props and they work just fine. Im not flying at full throttle at all but when im hovering low, i want to get out of there(in a confined space with a lot of trees, so when i gun it in a bad situation, i get 5 feet up and it quits, luckily i reset the throttle by going back to low and back up to half and saving the plane!!! But i still want the assurance that it wont cut on me. For instance today, a calm 2-3 mph breeze(barely detectable wind, nothing moving). I go take off, hover around 1/2 throttle for a minute, i roll out and go into a inverted flight up to a hammerhead, i increase the throttle for the hammerhead and it cuts.........I dont get it. Is it that im running apc props instead of GWS props??? are gws props lighter and draw less amps? Im getting to the point that i really dread trying anything new, that i cant get out of......Any ideas on what the problem might be????

    Status: offline     		Ok guys, I have some new info regarding the Tensor.

    Last night I went flying with Tony Stillman and Steve Rojecki. They both flew tensors around our local gym and trying various different things.

    They found a couple of things that I thought you guys would like to know.

    The CG recommended in the manual is incorrect. It makes the plane nose heavy during slow speeds. I noticed this too on my Tensor, it tends to drop the nose on landings. Apparently E-flite recommended a conservative CG for flyers not accustomed to flying 3D maneuvers.

    Last night, they moved the CG back from the recommended 2 1/4" to 2 1/2" that is shown in the manual to roughly 3". Both concurred that the Tensor flew MUCH better with this setup. I watched them fly the Tensor with the CG set this way, and I would have to agree, that it handled MUCH better at slower speeds. I think if you guys try it with the CG set at this point, you too will find that the plane flys much better.

    We also found that running the E-flite 370 outrunner, it needed a little more power to hover effectively. The 7.4 battery was changed out for a 11.1. The plane performed much better, with better vertical pull out.

    I have comparitive video, and will try to find a way to post it online as soon as possible once I figure out how to make it small enough to put up.

    Status: offline     		E, Would you mind rechecking your autocut voltages again and adding them to your last post?
    Are you able to measure your voltage (no load, and under load) and current, and add them to your post?
    Do you have a tach, to post your prop rpm?

    What is the temperature of your battery? It is not cold soaked is it?
    I think we need more hard data to be of any help.

    Status: offline     		I'll get some readout's tonight with rpms and amp load w/prop and w/o prop. 10by 4.7 , 9 by 4.7 and 9 by 3.8. All my batts are at room temp(around 70 degrees) when i go to the park, so they shouldnt cool off that quickly(its a 1 minute stroll down to the park......) I hope its just he heavy prop and not anything else. I have the cut off voltage set at 3v per cell, so its one of the options(the 9volt cuttoff, seeing as i run the 3 cell 860mah TP packs.....). Going to go get some data, probably post it late tonight or tomorrow morning!Thanks

    Status: offline     		Sounds to me like the BEC is cutting the motor off. Like it thinks the battery is low or something. The BEC is a safety measure, it shuts down the motor when voltage falls below a certain point and transfers all power to the reciever so the servos will work until you can land. That would also explain why when you pull the throttle off, and then on again it cycles and lets the motor turn again.

    Question is ...is it a incorrect setting in the programming or a defective ESC?

    Status: offline     		I reset if on purpose so i could have a little power to get out of an inverted fall----no thrust, you have a flying brick.....I dont think its the BEC. Check out these numbers from my astroflight watt meter.......THese are all taken at full throttle.....

    Prop Amps Rpms
    9by3.8 9.8amps 9,200
    9by4.7 10.3amps 9100
    10by4.7 13.2amps 8900

    I didnt bother taking the watts but heck that explains it. The batter at 10c will produce around 9 amps and at 15c (burst) it will give you 13 amps. As I just found out, burst only last the first time for maybe 4 seconds at most, then you barely get above 9 amps on the watt meter and it cuts off........I think its the props, they are APC slowflyer props, so they are big and heavy........I bet if i put gws prop on it would have less weight so that means less mass for the motor to turn , therefore less resistence and fewer amps.....making flight a little more enjoyable! What do you guys think, am i right in asuming that it is the props????
