Saw Impala in the thread s thought I would add mine.
It was built in the late 70s but sat in my loft for 40 + years . Converted to electric power in 2018 but finally had its ( and mine) maiden on the slope earlier this year. Thanks to Roger for the coaching!

Not sure about 2021 but I see Weston Park is still scheduled for October , pre sold tickets only and I am thinking about it ........

Thread: Horus 10X on FR Operating System
25/07/2020 12:03:12

David,

Glad to have been some help. What I forgot to add ,in case you have not spotted it. The full pdf manual download from the Frsky site is pretty comprehensive.

David,

I have had my X10 for 2 years now . I tried OpenTx on companion before I bought the Horus and thought ok I won’t have a problem with that if I need it. So changing to OpenTx I always had as an option. However I have found the FrOS so versatile and just as easy to use that I have never changed. You can use the ‘canned ‘ mixes if you want or there is a separate external mixer if you prefer. I used the canned butterfly mix for a glider the other day for the first time.; absolute doddle.

Help on ‘how to’ is indeed thinner on the ground but I have not found it a problem.

Telemetry manipulation is the , I think, the weakest part of the FrOS when compared to OpenTx but is still comprehensive. For example the Parameters available from the new neuron ESC are not logged and the BEC amps can not be seen at all. You can discover them on OpenTx. That links into the comment above about FrOS updates. We are still waiting for one that fixes that issue. That’s about my only real gripe.

My advice try it and see what you think. You can swap to OpenTx or Ersky at any time you want.

Thread: Cheap or good Quality Lipos ???
23/07/2020 12:57:09

I’ve had two of the cheaper makes go puffy . For the last 4 years just used 4 max. All as tight as ever they were. However as others have said doing the right thing by your battery and never abusing it is probably the real key to longevity. Perhaps I have just got better at looking after them. Not changing now though, that would be tempting fate.

Thread: 4 MAX Servos
23/07/2020 08:32:06

I have used the sub micro digitals in my gnat and they all work fine. I have run them at both normal and high frame rates and all is good so far but only a handful of flights so far.

i ordered the next size up for my latest model and also 2 of the mini’s , all digital mg. The mini’s were fine but I could not get the micro digitals to work properly ,specifically 1 of the pair hesitated and lagged behind the other .As they were aileron channels this was not good. George sent me another but I had the same problem. Frame rate had no affect on the behaviour. George could not understand the issue and had not seen it before. The assumption was some bizarre radio compatibility issue Which did not make much sense to me given the other servos were all fine. We swapped the 2 digitals for analogues and they worked perfectly. So that model now has 2 digitals and 2 analogues on the normal frame rate. About a dozen flights so far and all is well.

Aside from that anomaly they seem good and 4Max service as ever was ,as ever, very good.

Thread: Does anyone remember...
28/06/2020 10:38:22

Phil,

I was trying to remember the Walsall shop when I saw David’s post. Graingers indeed. I used to go over specially to admire the Macgregor Single channel sets they stocked. Eventually bought a Futaba Codematc single channel set.

My go to shop was Models & Hobbies in Wolverhampton town centre.

David,

the only model shop I remember in the area was called Penn models. It was run by the late Pete Littley who was a member of Kinver Aeronauts Radio Control Society as was I. Grand names in those days. The shop started life as an iron mongers and rapidly became a fully fledged model shop . I believe it moved to Kingswinford where it is still run by his son. As Penn and Tipton are not far apart it may be this shop you are remembering. Can’t remember any more in the immediate vicinity. If it’s not the right one drop an email to the shop , the son is sure to know if there were any more.

Eddie,

I can not remember if the motors in the Edf unit were stamped with the KV rating or not. Since you have deconstructed yours Can you see any numbers on the motor body ?

You did ! There are some flying shots on the lockdown flying thread if you scroll back a bit.

Thread: New EDF Mini Jets- Jet Provost & Folland Gnat
15/06/2020 18:02:16

Alex,

that thrust is way too low . There is a table on page 9 which lists my test results for a 3S set up using various size intake sizes. Although fully charged my lipo was only a 25C zippy. The 600 g thrust I finally achieved was With a peak current of 42A and an rpm of 49000. ( rpm was a factor of 2 out in my table as I used poles rather than pole pairs in my pre test setup!)

4max lipos are usually top notch and are my usual go to lipo. The zippy just provided a better physical size for this model.

Not sure what the problem is with your set up but a current measurement would sure help the analysis. Probably worth buying yourself a cheap watt meter. You just connect it in the battery lead and read the values.

Geoff,

have you flown yours yet ?
Mine headed for the sky’s last week for the first time, it was certainly very slippy well actually it was very very fast.

Take off with very little breeze was at only 1/2 - 3/4 throttle. Only had 3 flights so far but it really seams to be a very crisp performing aeroplane. Very pleased.

Ken has a good point and we have had one person who actually had a duff fan!

Definitely best to measure before you try to fly.

Tim

15/06/2020 13:21:32

Eddie,

Apologies I misread your post as about a Gnat not the Provost! Have not built that one but I think the same is true only more so. You need max thrust and lightest airframe you can. Maximising ( and I mean as big as you can possibly make it) the cheat inlet right next to the fan entry I think should be your next step. Up the battery c rating and measure the thrust before you try to fly.

Tim

15/06/2020 08:57:08

Eddie , mine certainly flew and there must be half a dozen more successful gnats on the forum (there is another mini jet thread ). You can see u tube video of my first flights at the bottom of page 11 on this thread.

your weight does not seem excessive but I would measure your thrust on a set of kitchen scales. It is crucial you get somewhere near the rated thrust value (600g).
Launch is the critical phase but it sounds like you have that bit under control so I am guessing low thrust is your real problem.

Similar question from me. What does it power ? I did not even know I had one. I can not remember it being mentioned in the manual.

Thread: Max Thrust Riot versus Wot4
10/06/2020 10:31:07

This does not really contribute to comparisons between the standard size riot and wot but I have owned a Riot XL since I came back into modelling in 2016. It survived being bounced around as I got back in the groove and I took my B test with it. I still take it our for a regular thrash. You might gather I rather like it. It does everything , flicks, spins, bunts the lot. Knife edge is a challenge but that’s me rather than the plane. Sadly they are not in production anymore, something to do with the Jig ownerShip when the factory making them went out of business.

Had my maiden Of Peter Millers Oodalallay today. Almost no wind. Peter said it would be quick , at full power it was blindingly fast ! Glad I started with some reserve and only used 3/4 throttle for take off. Flying was a delight, it is probably the most precise sport model I have ever built. Might manage a complete circuit at full throttle one day. Here's a few pics from todays 3 flights.
