Sunny Suffolk today which served its purpose twofold. Grass cutting first .... Flying next. In hindsight I should have flown first as by the time I was ready the wind had picked up. Never mind. Good session as she held the lines well despite the gusty wind. Anyway I got back down safely 😀

Well renewing the RX packs certainly put my mind at rest because I compared the Telemetry chart using old and new packs with flying the same aircraft and a similar freestyle aerobatic pattern. The old RX pack showed noticeable dips at times of high servo deflection. The new pack showed a clear improvement with very little voltage deviation during high servo defection. One thing which may have made a difference is the higher discharge rate of the Optifuel lipos compared to the Turnigy packs. Don't know for sure. I might have dodged a bullet there, but I can't take too many risks with these large scale models.

Like the build a lot, Chris. Nice work!

That's a sad tale. Some great flying on view by the way. If it's not councils reallocating land it will be a mass of solar panels in our rural environment. 😒

As a matter of caution I have replaced all my Turnigy RX 2S 3600 mAh packs as they are quite old and look suspiciously as they are about to down the puffy route. Furthermore, I wasn't happy with some of the telemetry data relating to the RX packs given I am using all digital servos. I chose some Optipower packs and truth to tell there wasn't a lot of choice of packs with that capacity. The only issue I have now is that I need to buy an MPX (male) charging lead ........ Better safe than sorry though.

My Mac (OS sequoia) has an M1 chip presumably that's the processor, so unlikely to work? Excuse my ignorance.

One star rating doesn't inspire confidence on the Aerofly 10 sadly.

Stupid question here. Based in the UK as I am, what RID would be compatible with Futaba gear and is it freely available, as it seems to be for Spekrum?

Hear, hear !! wish I could get out that much Leccy ☹️

Such dedication LF! Glad got some stick time in 👍

A bit of increasing jeopardy on this morning's session. The first one for a couple or three weeks due do working in school so I was gasping to get out from the cabin fever mode. Crops growing nicely (not sure might be barley) with a gentle wind down the strip. I was not sure of the wisdom of taking out the biggest of my squadron given I am a bit ring rusty. Hey Ho! I decided to get on with it. The one thing I had overlooked with the Edge is her tendency to bite if I don't keep the throttle open a 1/3 on finals. I woke up to that pretty quickly as she decided to impersonate an excited porpoise. I did a WOT and went round again. Bit of a basic error on my part 😝. Never mind four flights later I was almost back up to speed on the technique levels. Nice morning around though. 😀

Lovely golden retrievers, David. The model looks fantastic too!

I like your 4 column table idea, Peter. I going to adopt that straight away! I do check the pre-flight and post flight voltages and record them, although the IR readings are done less frequently. 😔

Wow! I wouldn't be too keen to come in to land just over those trees with a 2 metre job let alone that size of aircraft. Great video, but I dread to think of how much investment went into it.

Not on my desk top either, Ron Ahhh...... Got it to work now by refreshing the forum page!

Lost of interesting recent posts on this thread for the last few days now we are getting some decent weather 😀😎 No wind today so I dust off my sbach 342 the last time for which I flew was way back in February on a less than ideal day. Lovely sunny welcome at the field so off to work. It has only been 6 days since I last cut the field and those darn dandelions are out in force already. That's tomorrow's job sorted out. Anyway flying was enjoyable, although because she doesn't get many outings I did notice today a tendency to veer very slightly to the left into wind (from behind) which is corrected with a bit of rudder. I do wonder if a some side thrust needs to be added as my bigger scale planes have it built in. This early Goldwing kit doesn't possess any built in. A bit more experimenting needs to be undertaken I think. Despite this she is easy to fly and does some nice freestyle aeros.

Yup, been there, done that and wear the tee shirt ☹️. Still it keeps my repairing skills up to scratch!

Love it! Great job, Michael 👍

Thanks, Peter. Interesting. As I say the Rx battery is just just supplying the servos via the switch due to the OPTO nature of the ESC. I am a bit surprised to see this happening only when the ailerons on this particular aerobat are at full deflection. My other 2 large scale a/c using the exact set up (same RX battery too) and don't show anything like the brief large current draw on the RX battery (2s lipo) doing the same flying patterns. But I take you point about access and it may be be nothing worry about. I am going to go through the aileron geometry anyway this week because I am not happy with it and retest. As you say GG, until started playing around with telemetry I was happily ignorant. Now I am more inquisitive and want understand more. It just makes life more interesting for me.

Hi DickW, the wiring from the lipo is what it is. It connects to a switch from 4-Max which is sturdy enough I think and is the same for all my large scale planes. As it's an OPTO setup it only provides power to servos. https://www.4-max.co.uk/gt-electrical-switch-8a.htm I tend to think the evidence from the Telemetry/TX setup points to a servo on or near the stalling point , but I will test it all when I go to workshop this week. Thanks for the input, gents.

Well looking at the two aileron EPAs the RH aileron servo limit up & down is at 135 with actual travel of 115 and 140(!) respectively. The left aileron has a limit of 135 up/down with the travel set at 120 for both. Going to the sub-trim menu the RH aileron is +70 while the LH aileron is at -12. Something definitely not right there. Both servo arms need coming off with servos zeroed and start again. The throws when she was initially set up were supposedly equal, also I can't say I noticed anything untoward in flight either. I think anyway the roll speed can be toned down a bit to make it more scale like because as it is now this is not right.

I have had a look at the servo measurements, GG. The readings indicate a high level of rotation on the two aileron servos (probably non-scale rolling at the time), but with the throttle approaching WOT. The ESC is an OPTO and of course, as normal, there is no throttle servo. So you may have a point GG 👍 Looking at the charting on my two other large scale jobbies and doing the same routines, the most voltage drop is briefly down to 7.9v during the flights. So you are probably correct and I need to look at the EPAs carefully. I am the first to admit my EPAs are quite large (I don't do low rates or EXPO by and large!). Good time to check during the rainy week.

It is worry. I bought one of the last Capiche 50cc off them a year or so ago and I was told they were not going to sell any more" large " kits any more because of the cost of a courier. Also I was told I could only pay over the phone as the website was not up to it. The person I spoke sounded a bit downbeat even then. 🤞 they are still in business.

Trawling through the data on one of my large scale aerobats (Goldwing 91") I was looking at the RX battery and I was horrified at the gyrations during one flight! I am using a 3600 mAh 2S RX battery (12c). At the start of the flight telemetry indicated it was 8.2v (although my lipo tester said nearer 8.4v) which is starting point I expected. However, during the flight it hit 7.5v and then 7.4v! On my other aircraft there is some dips in capacity before recovering, but not this much. Scary. I wonder if the battery is nearing its useful life, although the discharge rate on both cells at the end of the flight are the same. It's got me thinking though ......

A one day weather reprieve in Suffolk today with almost perfect flying conditions. Best make the most of it. Like you leccyflyer I decided to squeeze one more session in because if the met office is correct this week is mostly rain and wind and hanger time beckons. The Goldwing Slick 91" came out and although the CoG is slightly rearward a great deal of fun was had with flat and inverted spins. This after the pilot got the de-misters working before starting engines!
