problem

Hi , im a newbie and this is my first plane. I made this from scratch , (used Depron Sheet instead of dollar tree) My specs : MOTOR : Turnigy L2855-2800 EDF Outrunner (630w) ( its ratted 4s) EDF : change sun 10 blade 70mm Battery : Zippy 3s 2600mah 25 c Esc: 40-50A HK (opto only) I took it for...

OK. So I'm a noob to this hobby. I got all my electronics to start some scratch build, and I built a nice FT slinger that I can't wait to get into the air.... But I accidentally left my battery plugged in and it ran way down... And I went to charge it it tells me that my voltage in my cell...

So I've finished building my first quadcopter following the Electrohub tutorial and hooked up a Turnigy 9x receiver. It appears to bind to the transmitter successfully, but when I turn it on normally and give it some throttle, nothing happens. The lights on the MultiWii board turn off as soon as...

Hey guys! So the other day my ESC came to a very hot and sputtering stop. So I decided to get a new Plush 30A ESC to replace it. After much foam carving to get at my bixler's connections, I finally replaced the ESC. I plugged it into the receiver and into the motor to give it a test. However...

So, my Quad has a KK2.1.5 board, Hobbyking Blueseries 20A ESC's and 1000kv Motors. With stock firmware on the KK and the ESC's it flew, but was very twitchy, even after tuning the PI settings. So I decided to flash the Steveis KK2.1.5 Firmware (v1.17S1 Lite). After that, it flew a little more...

Hey FT. *I am reposting this thread to this section under recommendation under one of the moderators.* I have a problem and I am hoping you can help me out. (I am not sure this is the right forum topic for this issue, but it is slightly related to customer support). I have been in the hobby...

Hey guys! So my dad and I just built our first quadcopter (Electrohub quad kit with the KK2.1.5 board, generic HK 30a esc's NTM Prop Drive motors) and we took it for a test flight yesterday afternoon. When we tried to put a bit of power and started increasing throttle to the quad, it suddenly...

Hi everyone! I am having some issues with my tricopter that I built recently, when I'm flying the tri one of the motors will stall for a second then come back on. It does this randomly when it's flying and has not resulted in a crash yet. The set up is David's Tricopter Design with Afro 30amp...

Hello, so i've built davids tricopter 2.65, but with a 3s battery(2800mah,30c). The problem is, when I arm my tricopter I need to apply ~3/4 of throttle to get in even moving from the ground, but when it lifts (~1cm) it just goes forward and to the left and almost flips, without me touching...

Hello Flitetest community After a minor crash with my tricopter it seems to generate way less CW torque than the FC expects, making the tri spin CCW. To compensate, I have to bring the tail rotor in a position where it's sligtly tilted to the left rather than being tilted significantly to the...

Hey guys. I recently went flying and tested a new 2200mAh 3s turnigy battery on my tricopter. After one bouncy landing, it went head-over-heels. The KK2.1 board was initially alright, but when I unplugged the battery and replugged it, something went wrong with the screen. I have the image...

Hi, I'm using a Mobius cam as a dashboard cam at the moment, but it has a slight jerkiness to the footage which puts me off getting another one for flight recording or FPV. I'll upload an example video to youtube and hope the problem is still visible. It's a Mobius with a wide lens Recording...

Hi, I have a problem with my FOX-800A 1,2GHz VTx I bought a few months ago from a second-hand. It only seems to transmit on a single channel - no matter which channel I choose receiver gets video only on a channel 2. It's also very sensitive to any obstacles and antennae positions (even if the...

I've got an issue that I can't work out, hoping for some new insight. My quad is a symmetrical (no dead cat like setup) x configuration. The arms left front and right back react really snappy, but the other two overshoot like crazy. This is most noticeable on moving diagonally and yawing...

I have a problem with the KK2 board and self levelling (I assume). When the quadcopter tilts one way instead of powering up the 2 lower motors to level it out it powers up the upper ones causing it to flip. This only happens with left and right (aileron). I've noticed that the aileron channel...

Hi all, I'm a noobie that was inspired by David's tricopter 2.5 blog all that time ago. It's taken me until now (or rather until 2am last night) to finally build it. Everything went extremely smoothly and I was very pleased with myself :p I've been setting up the TX and testing the motors...

A while back I added a few articles to my "bookmarks". I can access them on my profile, but when I click "remove from bookmarks", it does remove it, but when I come back to the page it still has them there. Also, if I try to add any bookmarks, they don't show up. Does anyone know why this is...

Hey guys, I have a Turnigy 9X, I have modded the radio in almost every way possible. Most notably after the radio fell off my piano snapping the antenna, a SMA for antenna and module removal (If you ask nicely I can write up an article on how to do it as well as all my other mods). I recently...
