Ronos

Just flown her the once and was hand launched. She was no problem just a small bit of down elevator and she was better on small rates, she looked awesome. I covered her in light glass with Poly-C with at least 6 coats on, primer a light sanding and then airbrushed.

Thanks chaps, but the other half was at the top of the plan. Sorry for wasting your time.

Hi Robert, just come across your build, looks really nice. I liked the look of the Sunderland, so at the start of the first lockdown sent for one and began to build during the lockdown. Here are a couple of photos of my finished one.

I am building a B-17 that requires the fuselage to be built in two halves, but there is only the port side on the plan, what is the best way to build the starboard side?

Thanks chaps, that will do me nicely, was just experimenting to see when the LVC would kick in. I'll know when to land now.

Used a watt meter, and was running a couple of notches above half throttle, pulling approximately 500w.

After setting the LVC to 2.9 on a 4s lipo (esc manufacturer recommendation, with it being a multi motor model),which comes to a total of 11.7v. Is it normal for the LVC to cut in early, let's say 12.8v.

I have programmed three AS3X636 RX using the series on YouTube by Dave Marshall, and all have worked fine, normal flight mode, AS3X stabilizing mode,and panic mode,all ok. my latest one has hit a wee problem and the problem is, there seems to be no AS3X stabilizing mode when the model is moved from side to side, up and down etc, also when in panic mode there is no movement in the rudder, but all other control surfaces move as they should. Anyone else encountered the same problem and if so how did you rectify it. Thanks Ron

Fist of all, many many thanks to all your input and knowledge. I have re-programed the four ESC,s to 4-Max re-programing card ,(let's say default settings) and after a quick test and on a not fully charged lipo, the two outer and the two inner are putting out 195 watts 10.6 v on the lipo. All four connected to one lipo are putting out 390+ watts with the same voltage on the lipo. PeterF, I will do a better check to your recommendation, when I get a bit more time. Thanks all

Reversing a propeller simply makes it produce thrust in the same direction - but horribly inefficiently. It might be worth training the ESCs on the AUX channel separately. Edited By Martin Harris on 15/09/2020 15:36:25 Hello, I am not putting a prop on backwards , the set requires 2x standard props and 2x pusher props

Posted by Colin Low 2 on 15/09/2020 12:52:08: RONOS, "Two are standard and two are pushers". Do you really mean pushers or opposite rotation? Why not email George at 4-max and ask him. He actually owns and flies the original Tony Nijhuis Sunderland as featured in RCME. Sounds like cheap batteries to me and the voltage is collapsing as mentioned by Martin. I run a Tony Nijhuis Lanc on a single 3S5000 and can get a good 15 minutes flying on a calm day, never had any problems with batteries - 4max supplied. Hi, the set up is from 4-Max, with the same 2 standard and pusher props that George recommends. I know he runs his on one lipo and like you gets a flight time.

What I have noticed this morning is that all 4 motors are not starting at the same time. The two outer motors which are knocking out approx 305 watts are starting on a click of the throttle and the two inner motors kick in on another click. I have them on two different channels on the RX, one in the throttle channel and the other in the aux channel.

Posted by Martin Harris on 15/09/2020 01:36:56: Do you really mean that all 4 props are identical or are two of them pushers? If the latter, it might be that despite the sizes being identical, the pitches are a little different. Swapping them with the other pair and reversing rotation of the motors before measuring again would prove this. Two are standard and two are pushers.

Martin Harris, what i can tell you is all 4 motors, 4 ESC, the the 4 props are identical. The two outer props are running anti clockwise and the two inner clockwise and have removed the red wire from two of the four ESC's as the diagram on the 4Max website. I want to run two lipo's , one for the outer and one for the inner, just in case if one goes down then i might have a chance of getting it back. I will charge the lipo's up again, and see what they read and do a bit of swapping about and also run them in parallel as you suggest .
