Cliff 1959

The outlets are two 'spoons' either side of the cowl, not even as big as the inlet though, cheers Geoff.

Right, here's the result of trying the esc in a model with the same motor ... six minutes in and hey presto the problem occurred again ... motor died and the esc went back into connection mode with the beeps, closed the throttle and the motor beeped four times and it fired up again, it didn't do this on this deadstick flight though! Perhaps it was a lot hotter. Anyway thanks all for the ideas in conclusion I'll increase the air outlet hole in the cowl and install an 80amp while I'm at it, thanks again, cheers.

Hi Andy, I guess if I swop the esc into another model and put that esc into this model it would identify the faulty component, the esc has been fine up until now but probably less than 10 flights in all, I wonder if it turns out to be the esc can the manufacturer fix it?

Hi Denis, This time it didn't go to full chat just beeped continuously then failed, switched off the tx and it reset the esc but wouldn't run until the tx was switched back on again.

Here's the video of it happening in the back garden chaps: https://youtu.be/QhJXrBemeqo

Guys I'm just rendering a video of my garden experiments, I performed individual cells checks as it was running and the problem occurred at three minutes, and to top it all another fault appeared! The motor ran to full throttle before quitting to a tickover then couldn't be shut down without disconnecting the battery! Then I tried a second test without the cowl and after about 90s the motor reset with the usual esc connection sound. The voltages by the way all stayed close together but did drop to about 3.9v per cell. Anyway you'll see the video later on today. Cheers.

Hi Phil, I set it up on the throttle output on the transmitter, in this case a Radiomaster TX16S, I guess most radios are capable of this. It's just like restricting the amount of travel a servo has (but I'm no expert!), cheers.

Hi Brian, from the time the problem started to landing and disconnecting was three minutes, after a further 7:45 seconds I reconnected the motor and it ran normally, (I've just reviewed my video) for the timings. I can try what you suggest, I'll need to charge the battery first though, cheers

Hi guys, the motor is a Tornado Thumper 4205/06 980w 800kv, the esc is a Overlander XP2 60amp, the battery a 4s 5000mah Turnigy Rapid with about seven charges on it (also used without problems in an edf). The beeps were continuous and fairly rapid, possibly two a second. The esc is on the bulkhead and is directly behind an intake hole in the cowl, the motor control is set to a maximum power of 75% to keep the amp draw to a maximum of 55 amps. The model floats around on about half throttle although I couldn't say what the amp draw is at this setting it must be pretty low, some of the time I'm actually gliding power off. All the power connections were made by me using 4mm gold connectors securely soldered and properly sleeved.the esc to battery connection is an XT90. I'll check connections.

A funny thing happened yesterday flying the vintage Mercury IV. I was four minutes into the third flight at about 100ft (fortunately) when the motor started to let out loud beeps and stopped working. I still had servo control so, with the motor continuously beeping, I managed a reasonably good deadstick landing. About five minutes passed as I retrieved the model back to the pits and removed the cowl to examine the esc, the motor was warm and the esc not as much. I reconnected the battery and the motor now ran as normal. The battery still had 60% charge. The motor is a Tornado Thumper bought new for the model, as was the esc, she's flown less than ten flights. The beeping noise is usually associated with a connection problem between the receiver and esc, so is this a clue I wonder? Any ideas guys, should I try a another esc?

Thanks Matt, almost on my doorstep too, cheers

Does anyone sell 4mm balsa sheet in the UK does anyone know?

I saw your post on he VMC page, could you build from a plan?

I see SMC do a kit Mike https://sussex-model-centre.co.uk/products/westwings-aurora-glider-kit
