[QUOTE=meowzy;20620353]I'm totally new to this.. set everything up and did pre-flight checks, about 3-4 minutes into maiden flight I noticed the motor rpm dropping and losing altitude but servos were still responding..

Where did you purchase the plane?
I have not tried the tx/rx that came in the RTF yet. I need all the radios I can for the kids...I will post if I have any problem and solutions if any. What Brand is it?

AJ,

Check out the removable tail mod that Lafayette did. It might deserve posting a link at the beginning.

Thanks!
Like I said, i have others things that I will post as they are accomplished.
I just got the plane last week and I want to do all I can come up with to make it better, with clear explanations on how I did it. Can't do paint inside and freezing temps an 50 mph winds outside have stopped me in my tracks!

2 days later I plugged the battery back in ( and has not been charged since) and everything is working except non of the servos are centering correctly. I charged the battery to full capacity and then played around with the servos to try and center them for about 30 min, adjusting trim on tx with no success (they are waay off to one side) and plugging/unplugging the battery about 10-15 times... and then randomly everything stopped working again. The ESC is not hot and I measured the bec output and its at 5v, so the rx is getting power. the servos make a quick sound but that's about it, I have no servo/motor control again..
I can re-bind the rx to the tx however with the bind cable. When the cable is plugged into the rx it will start flashing fast and then stops when the tx is turned on. The battery is at 11.1v when everything stopped.
Do i need new ESC, rx? I really dont know whats going on here. Any help will be greatly appreciated.
It's difficult to diagnose these things without being able to see it in person but I'm inclined to think it's definitely your rx or esc. I'm leaning toward your rx given your symptoms. One thing you might try is to plug your lipo in with your TX completely off. There's a chance that your transmitter is causing the problem. If your servos are pegged with the transmitter off then you can be pretty well assured that your rx or esc needs to be replaced.

I assume you're using an rtf TX/rx. I was tempted to go the rtf route when I first got into this hobby, but I'm glad that I plunked down a couple hundred bucks for a decent radio up front. I've had zero issues with my dx6i and it offers some basic programming functionality. If you find that any of the radio components are shot, I would consider investing in a good radio. The cost of brand name receivers may be high but if you go spektrum there are cheap alternatives. Although I use an AR6210 in my SS, the orangerx dsm2 receivers from hobbyking work fine for park ranges.

Thanks for the reply... By servos being "pegged" do you mean when they dont center? Everything started working again so I tried what you said, with the tx off, non of the servos center correctly.
Im using the flysky 4ch that came with the rtf. I realize now buying rtf was a bad mistake..

Do you know that 12.6 is full charge on a 3s?
Can't tell from your voltage data.
11.1 is usually where mine is when I come down.
The 10.6 you spoke of is quite low.

10.6 is lower than I normaly go but within most manufacters specs.
Sanyo (leading supplier) rates their cells as having a range of 3.0 to 4.2 volts. To prolong battery life most R/C suppliers recommend 3.2 volts as the lower limit (9.6 for a 3 cell pack).
Way more info than you will ever need on Lipo's at: http://www.rfcafe.com/references/ele...ry-li-poly.htm

Don't forget the difference between load and no load cell voltage, 3.2 is safest low under LOAD voltage.

I didn't ask before because I assumed it wasn't it wasnt the case since you'd flown your plane but is it possible that your servo arms are in the incorrect position? Are you still unable to move your servos? If not, can you move them in both directions about 30 degrees? If you can, then you need to reattach the arms when the servos are in their neutral position. Whenever I get new servos, I center them before attaching the arms.

If they only have full range of motion in one direction or don't move at all, something is up and I would follow my previous advice.

Many of you have seen this clear belly pan and clear canopy set for the Easy Star by Park Flyer Plastics. Considering most people here cover the bottom of their fuse with tape, the belly pan should be something that many people would want. I was told by the person there that he would be willing to make one for the SkyS/Bixler. Is there anyone willing to send their fuse to him to create the mould for them? I don't have one anymore (will eventually). He's near Dallas/Ft Worth, Texas. Maybe you'd get a free belly pan out of it?

Flap install

I've learned so much lurking around here, thought I'd post a few pictures of the flap install I did the other day on my SS. Not too much detail.

One thing of note is I was leery of cutting the servo flush with the wing bottom with it being so close to a main stress point (fuse) and next to the spar. So I compromised - this wing has so much lift it won't matter. I did inset the control horn else the screws for the backing plate would be too short, set with hot glue, shoved pins into the screw before the glue set else getting the screws in would be difficult.

Also, I chose to orient the control rod and connector this way because the wire size fit the control horn nice and snug, same with the connector on the servo. Had I gone the other way, it would have required drilling the servo arm and the connector would have been sloppy on the horn. YMMV. My first such mod of cutting a perfectly good wing. Always learning.

I used a couple of Spektrum S75 servos.
