At last sorted out my QQ Super flight controller. The instructions show the AER receiver inputs as having the AL top ELE Middle and Rudder bottom. this is misleading and incorrect. Rudder brown goes to the top where the arming, disarming sensor calibration go Aileron goes bottom. After this everything is fine. performance is steadier than the KK2 board which had a mind of its own at times. The QQ is better for the new quad flyer, the response is predictable but its quite lively even on low gain & found it different but certainly manegable, I purchased mine direct from HK £10.30 free post arrived in eight days.

Hi, I am in trouble again & just hope someone can help. I have two QQ flight control boards and they both are giving me identical problem. I have two quadcopters one running on Futaba T6Ex and the other on Skyfly CT6B both working fine, because of the good reviews on the QQ flight control board I have decided to change from the KK2 boards. I have connected up the new boards exactly as the info sheet, get as far as transmitter calibration which is confirmed by the led coming back on. But I cannot get any response from the throttle lever on channel 3 or disarm or do a sensor calibration. The green light just stays on and nothing. I have the same fault on both boards with two different Radios which are working fine. all my connections look ok. I have tried moving the trims on the throttle levers but nothing. I can't think what the problem is & I hope someone out there may be able to help. Because I have the same fault with the two boards I am assuming its me doing something wrong. regards Max

I have been flying models since early seventies, but over the last nine months I have had 3 self build quadcopters 600 size all with the KK2 1.5 flight boards which I have found awkward to set up. The main problem I get is that after putting all the gains & limits etc I can get the Quad to fly, but they are never reliable in the hover. With the ratchet removed on my Futaba T6EX, the stick is smooth but after precise adjustment the hover is achieved, but will not stay there , after a few moments the Quad at that throttle setting will either climb or fall to the ground then acend again & just keep going up without any throttle movement. I try to maintain a hover but its unreliable as sometimes the increase in height is quick & just a small decrease sends it down saved by opening the throttle. On all my three Quads its the same, I have adjusted the throttle stick scaling , gains/limits on self level & height dampning to all different settings but it stays the same. I cannot to fly the quads properly because 70% of my effort on the box is just trying to achieve stability before moving on. I fly my Quad at my local club site. I can do to & fro, plus walking the quad but because of the constant risk of increase or decrease in height its difficult. I start my flights with a 2200 3s at 12.60v for five minutes & land with 11.4v. So there is no lack of power. I have now bought a QQ Super flight control board to go into my next quad & see if its any better. Any advice on my hovering instability would be appreciated. Regards Max

Hi Chris, What would be the result if I were take off as normal with vectored thrust in horizontal all 4 motor facing forwards with wheels fitted 2 main on a U/C with a tail wheel or skid to help directional stability on the take off run, then rotate as a normal aircraft. When at a suitable height I good graduate. To semi hover or full hover any probs I could glide down and land dead stick on the U/C. I do like the idea of a KK2 flight controller, but I can't quite understand what would happen when I want to swivel the motors horizontal for normal flight when I would need to use my ailerons / elivator servos. I don't understand what being flashed with special software really means, where would you get this software from and would it be able to transfer from quadcopter mode to normal aircraft mode and utilise the onboard servos for normal flight and linear throttle control . Regards Max

I am in the process of making the parts to convert a Bixler2 into a VTO & Landing model. There is a good example of this on u-tube, where the pilot has good control over the model, the video was taken at NASA in the States. The only information I have is taken from the video which is handy but not very accurate. At the moment I have made the two horizontal beams which hold the fore & aft motors 9" from the centre line of the fuselage the motors are 18" apart with CofG in the middle. I have swivel brackets to house the motors which will be moved via a servo & linkages on each beam for lifting and forward flight. I have 4 E-Max CF 2812 1500kv motors fitted with 7" x 3.5" 3 Bladed props, matching a 30 amp ESC will be fitted for each motor, hopefully all giving the same thrust, a max of 20 ozs. My main concern is that during the lifting period there is no pitch control the elivator will be ineffective I will rely on equal thrust from each motor to maintain level position wind would move it about a bit but the pitch should stay the same as on the utube video the pilot transfers from lifting to normal flight with ease via a rotary switch on the TX. Club members have said to me pitch control or the lack of it could cause the model to tip over & suggest that I should treat it as a Quadcopter & fit all the necessary software, I know nothing about quadcopters apart from the fact that don't function like aeroplanes, it would appear to be an over complication my Bixler2 will behave like a normal aircraft after leaving the hover . I have also heard that small computers can be used to improve the handling of a VTO & Landing plane. Should I continue slowly with care with manual lift & tilt or could this be difficult, I have 40 years of flying models with the usual good & bad days. Has anyone had experience of quadcopter functions applied to a conventional aircraft set up, are there any small computers that may improve the handling, any advice would be appreciated.

Hi Tom Today the Welsh SFH Cranefly had its maiden flying session. Forecast was for dry with 5 mph westerly . On arrival at our site its was drizzle & wind westerly 10 to 12 mph after some Helicopter boys left I ran out out of patience & went for three blade runs in the hand. I then went for real, launched at 3/4 throttle lifted but the wind caught it & it sank to the ground then fell over no real real damage the prop saver worked a treat & there is a blemish where the blade roots came together but no real damage. Lesson one autogyros need bags of power to maintain directional stability in wind. Checked everything out all ok- went for another try on full power went up like a bird, but had to work on the roll control I found it over sensitive but manageable but I was neglecting the pitch control & it was being tossed about by the wind but landed just down wing a bit on two wheels. The third flight was better , gained more height as safety insurance & started getting used to it flying up & down the runway & making a reasonable landing, I shall reduce the roll control by about 5 degrees which should smooth things out a bit. Thank you again for such a good design for a basic trainer, which I will fully exploit. I am making another set of blades medium balsa with spruce L/E .
