  1. I'd be tempted to speak to the gliding club. There's also a small free car park just S of the club on the road that goes past it. It's a very short walk to the S'ly White Horse slope from there.
  2. Used to fly off Sutton Bank in the 70s - over the White Horse in a southerly, or walk round the point to the cliffs in a W. Nobody ever mentioned the gliders although the model club may have spoken to them - I was too young to worry TBH. Have you looked at the ridge to the N of the main A170 road/visitors centre? It's a short walk through the shrubbery to a clear patch where I've launched and landed a hang glider back then as well.
  3. Myself and my brother had a few models in the 70s including an Elmira and it really didn't want to turn. Another chap flew one with ailerons and it was a massive improvement. I'd probably add flaps these days to give full length ailerons/in board flaps/crow brakes.
  4. I flew an Easyglider and the only problem was getting it down. So I changed to a Heron and the addition of crow braking made it perfect. TBF If I flew a slope I'd probably have stuck with the Easyglider. I'd also say get a vario installed to make it easier detecting and staying in thermals.
  5. Thanks for that link. I haven't had any problems with telemetry and signal RSSI seems good in the Heron ATM with the rx aerials as situated. I'm loathe to dig out the rx again to check as it's tucked well away - maybe if I get bored. I'll see how many RSSI warnings I get once the thermals get better and I push further.
  6. Interesting replies, thanks. I'm flying a new Heron and haven't got to the limit of radio range yet - Radiomaster TX12 and FrSky GRX8 receiver. When it was in my Easyglider it was a bit more cramped so the rx aerials were not ideally positioned, but the Heron has more room and that has obviously made a difference as RSSI seems better. It hasn't really been the weather to fly it to the limit but spring isn't far away.
  7. I fly thermal and generally push upwind until I get RSSI warnings. I want to set a fail-safe for gentle flat 360s in case I lose range, and then the breeze will bring it back closer. Any slight rudder causes it to wind into tighter turns so I wondered if anyone had any suggestions? A smidge of aileron would probably work, but up or down? I wonder if down would be better as any speed increase would cause extra drag and maybe help flatten the turn.
  8. After a bit of overnight glueing I was able to fly again today - another lovely blue afternoon and some nice floating around to exercise the tree landing demons.
  9. Maidened a MPX Heron in the lovely calm high pressure air today. No lift but ideal for sorting the flap/crow mixes which need a good amount of down elevator. Was all going swimmingly until the final approach which ended in a rather large oak tree. Luckily it was climbable and after a bit of judicious pruning I was back on terra-firmer, less terror and more firmer. Minimal damage; control horns came unglued which possibly saved servos, and one tip cleanly broken off so easily fixed. The various dents steamed out quite nicely using a kettle - be cautious doing this as too much steam raises the foam into unsighly bumps.
  10. Update - Teknistore supplied a new one at half price. I then looked at the faulty one, removed the hotmelt on the pcb holding the three wires and found a dry joint which I resoldered. So now have a spare which I doubt I'll ever need (touch wood).
  11. I opted for the budget RM TX12 and found it ideal for my flying - Opentx Companion is great for learning and setting up plus there are plenty of YouTube videos showing hints and tricks. I use this safe throttle setup which I'd never have thought of; probably works for any Opentx radio:
  12. It first manifested as full rudder deflection on my Easyglider after 20+ mins which made for an interesting approach and landing, luckily a perfect touchdown. I suspected servo/receiver connection so unplugged/plugged etc and all worked. At that point I reduced the rudder throw which made the next fail after about the same flying time a bit easier to handle! I then realised I could check the transmitter display and this showed the stick input signal was the problem, not the channel output. As the Hall gimbals were £12 ea. from China via Teknistore I guess they're not top quality. I've swapped it out for the OE potentiometer gimbal and may stick with that. TBH I've been flying rc for 45yrs and never had an issue with pots but was lured into buying the Hall gimbals by the perceived better reliability and quality etc. so now I'm wondering if it was a mistake. I'm lucky it was rudder that failed not elevator or ailerons as I doubt that would be a landable situation.
  13. Yes I was looking at those and wondering . .
  14. The gimbal is for a Jumper V2 or Radiomaster TX12 transmitter - the gimbals are identical and I'm using a TX12. Looking at the spec it says; Supply Voltage (VCC): DC 3.0 ~ 3.5V Sensitivity: 2.50 mV/G Linear Output Voltage Range: 0.1- (VCC +0.1) V≤≤ Quiescent Output (TA =25°C B=0 G): 0.5 × VCC The actual small pcb is approx 13x7mm with the sensor plus surface mount biasing components. The sensor has 009 470 92 on it but I can't find any references via Google. It seems to fail after about 30mins so I'd guess it's a fault with the components rather than the wiring although I will try checking/resoldering the leads. The plug and leads look OK. The gimbals seem to be out of stock on the cheaper sites - I'm currently exploring getting an exchange but I'm not hopeful. That is why I was looking for a cheap fix and hoping to find an unwanted gimbal/sensor lying around that might fit. - attached is a picture.
  15. Hall effect sensor wanted to repair a faulty gimbal. Does anyone have a broken transmitter with Hall effect gimbals, or a faulty gimbal to cannibalise?
