  2. Damn it, I searched for the balsa version 🤦‍♂️

  4. All it means is that male PCSOs will be given black and yellow stripey uniforms, have their tasers taken away and be told to get there ASAP.🤣
  5. Just checked and the 10x6 and 10x5 current draw are above the motors max 18A rating.
  6. Looking at the plans, you are probably going to want to use a much smaller prop if only to improve hand clearance when launching. This would mean using a higher Kv motor, probably between 1700 Kv and 2000 Kv, or running on a 4 cell battery. On a 4 cell battery, this is what you get with and 8x5 APC-E with that motor Remarks: Battery Load: 10.63 C Voltage: 14.25 V Rated Voltage: 14.80 V Energy: 23.68 Wh Total Capacity: 1600 mAh Used Capacity: 1360 mAh min.

  7. What is the distance between the booms? It will dictate the max prop diameter.

Therefore the static thrust and max. current may not be reached. On ground you will measure *Stall Thrust* as maximum. 27.0km/h / 16.8mph - above this airspeed stall at the propeller blade will have disappeared completely.

  10. Don't forget to fit the table lamp into the port engine exhaust, probably won't fly without it.
  11. Why is it that you always get a puncture in the tyre with the most tread remaining and not the one that's almost bald?
  12. Have you checked page 21 of the receiver instructions, "aircraft will not respond to throttle but responds to other controls"?
  13. Sounds like one of the steps in programming AS3X and SAFE is interfering with normal throttle functioning. Having programmed an AR630 I can only say that the programming process is somewhat complicated, took me several tries to get it working. I'd go through the forward programming menu and double check that the throttle function hasn't been set to "inhibit" in any of the options. Unlikely to be the ESC as it just supplies power to the receiver and accepts the receiver output controlling power.
  14. Actually, I think that he battery can be charged using a standard lipo battery charger but a JST 2.0 PH battery adapter lead will be required. The battery plugs into the adapter lead and the lead has connections that plug into the balance and charge ports on the charger. I use this system on the batteries for my Blade 130X helicopter.
  15. Could have been worse, he might have found the bin liners, gone to a till and said "can I pay you for seks?".

  18. It's either a problem with the battery or a parasitic drain on the Tx. Can you swap batteries between the DX6 and DX8 to determine where the problem lies?
