About A470 Soaring

This is the blog for a few guys who spend their time flying radio controlled gliders, or slope soarer's, from the many and varied slopes around SE Wales.

This usually begins at the northern end of Cardiff, driving north up the A470 up to the Heads of the Valley's and the southern fringe of the Brecon Beacons. But the A470 road continues its windy way all the way to N Wales.

There are many slopes available for most wind directions, the most famous being the area between Nant-y-Moel and Treorchi known as The Bwlch, which has some of the best slopes and flying in Europe with many F3F competitions being held there each year and visited by many fliers from Europe and around the world. At 1500 feet (450m) above sea level, there is usually more wind than not, and certainly more than at sea level.

If you require any further information, are new to slope soaring or are visiting the area, please contact Steve at steve.houghton59@gmail.com . I look forward to hearing from you.

New Glider Project Part 2

 It's been a few weeks since I've done anything much on the streamline 350, partly due to me being side tracked by completing the Bird of Time and partly due to other commitments, but I did manage to get some work done to it a few evenings ago after work.

So, I soldered an XT90 LiPo connector to the ESC, (I'd had to order that connector) and fitted the ESC into the model. I'd also ordered a RX and fitted this temporarily and then came the job of setting up a new model on my Hitec Aurora 9 TX. Now if you're not familiar with this TX, when you set up a new model the TX asks you what kind of aircraft it is? I clicked on glider, then it asks how many ailerons & flaps it has, whether it has spoilers, retracts, a motor and whether it has a normal tail or a V tail, then once that has been completed it automatically asigns a channel for each control. I then needed to bind the RX to the TX and that was all done.

Then I needed to calibrate the motor so I switched on the TX and pushed the throttle stick all the way to the top and plugged in the LiPo to the ESC but all I got was a continuous beeping, which was not what I was expecting. I checked and I'd plugged the throttle lead from the ESC into ch8 of the RX instead of ch7. Doh! I switched it all on again and I then heard four beeps, indicating the 4 cells of the LiPo, but nothing else and it didn't calibrate.

I did a lot of head scratching and then decided to look at the TX programming for my Multiplex Heron, which should be the same. All appeared OK. More head scratching. I then clicked on the monitor funtion on the TX which shows sliding bars whenever a control stick, slider or switch is moved. The throttle on ch7, (throttle) moved OK so I then checked this on the Streamline program, but when I moved the throttle stick (J3) nothing happened and the bars didn't move. So I went back to look at the channels again and saw that the throttle had been allocated to ch7 but, the TX didn't automatically allocate the stick. Once I selected the left stick (J3), the sliding bar in Monitor was working so I tried to calibrate again and bingo, it worked, although the motor wouldn't turn, so I swapped two of the wires around at the motor end and the motor turned, and in the correct direction also, hooray 😊. All I needed to do then was set the brake and that was all done.

My next jobs are to connect the rudder and elevator control rods to the servo arms, fit the wings to the fuse and work out which of the wires already pre installed from the Multiplex connector in the wing root into the fuse controls which aileron and which flap, if that makes sense, so I can plug them into the RX. I then have to set up the control linkages on the wing servo's with power to the servo's and attach the servo covers, then I think that's it apart from setting up expo, dual rates, crow or butterfly. All I will need then is a suitable day to give it a throw into the wild blue yonder.
