|Thread: Heathkit manual|
Here's the review from the Oct 1968 edition of the RCM&E, it may be of interest to those who remember it & an education for those who don't. The price of £130-10s is the equivalent of £1,945 today for a 5 channel build-it-yourself outfit which rather puts in perspective the costs mentioned in a concurrent thread.
|Thread: Spektrum NX6 Rx Voltage|
Chris, have a look at the Spektrum Air Telemetry webpage for the various sensors that are available. Link
|Thread: WOT 4 FOAM E - engine wobble|
The following is an extract from a typical Multiplex instruction manual. Multiplex uses their own proprietary EPO labelled 'Elapor' but it is very similar in characteristics to other EPO's so I'd be vary weary of using epoxy, and if you do test thoroughly:
UHU Por also does a good job & some of my Clubmates use Gorilla glue successfully, personally I find it messy & unsightly.
My standard methods to spray one half with activator & allow it to evaporate off. Use medium cyno (I prefer green Zap) on the other & bring the parts together. It produces a bond stronger than the components with no mess. Do allow the activator to dry off before bonding, it will still be effective but you don't get the crackling, fumes & heat that wet activator generates.

Just came across this photo of the JDM Lanc with Dave Wright, from RCM&E Aug 1978:
|Thread: Lone flying during Lockdown|
I'll leave it there & agree to differ.
Again I would ask you to read the wording of the Government guidance that I quoted -
"However you can and should still travel for a number of reasons, including:............
Doc, yes I agree, it was your contention that you cannot drive to fly that I was disputing.
From a BMFA email sent to Club Chairmen & Secretaries yesterday:
Model flying itself has not been prohibited during the lockdown period and as an outdoor recreation may possibly continue in public open spaces dependent on any local restrictions. BMFA insurance remains valid as long as you are operating lawfully. However, legislation limits outdoor gatherings to no more than 2 (unless from the same household) and the BMFA advises that members do not fly alone for safety reasons.
Not true. From the Government guidance:
If you live in England, you must stay at home and avoid travel in the UK or overseas, unless for work, education or other legally permitted reasons. If you need to travel you should look to reduce the number of journeys if possible.
However you can and should still travel for a number of reasons, including:............
I'm not advocating that you do travel but let's get the facts straight.
|Thread: Aeronaut Prop Replacement|
I also fly off grass Capt. It may be that with all the rain we have had of late some of it may be down to water erosion from spray being picked up. The model is quite highly powered with an Axi motor.
Notwithstanding this I'm very happy with the Aeronaut propellors performance and will continue to use them as a first choice.
For balancing, as you say they are pretty good out of the packet but if need be I use the APC recommendation: "If your propeller requires a balance correction, we recommend that material be removed from the upper and lower surfaces at the tip of the heavy blade. A piece of clear tape can also be added to the light blade, recommended for electric applications only."
I'd agree with the path you are taking Martin but if you get desperate check out the Continental shops such as Lindinger who I have used a few times (but not for raw balsa) & found to be excellent and Pichler. Delivery costs & time are comparable to UK suppliers.
|Thread: Aeronaut Prop Replacement|
By coincidence I noticed last week that the trailing edge of the Aeronaut prop on my Wot 4 was starting to erode after about 180 flights & needs replacing. So there may be something in it, but I will continue to replace 'on condition'.
|Thread: DX9 Start Up Warning|
The only way I have found to do this is to assign a spare unused channel to the throttle cut switch, say in your case, Aux 4 to switch A. The switch then has two functions, Throttle Cut & Aux 4.
Then in the Warnings Menu assign a warning to Chan:Aux 4 Under 0%
That does it for me, the system will then not start up unless the switch is in the Throttle Cut position & you get an audible warning, just like when you switch on with the throttle open.
It works even if you are using, say, a 4 channel Rx that does not have Aux 4.

|Thread: BEC output voltage|
I'm with Frank on this, the higher the voltage the lower the current for any given load.
But if you want to check the draw at various settings this little gadget is a useful tool.
And finally I would highly recommend the Optipower Ultraguard, mine saved one of my large scale models following a power failure.
|Thread: S9154 Servo Arm|
It may also be worthwhile posting on the GBRCAA Forum, their Members are the most likely to have spares lying in a draw.
Specs here - it may be worth dropping them an email
"Notes: No other arms will work on this servo, because of the unique spline size.

|Thread: Where have all the Lipos gone?|
If I was a retailer I'd be running down my LiPo stock as winter approaches.
That said there are still plenty available if you look as posted above, also try RCFerret
|Thread: Choosing my first charger|
I've an ISDT D2 charger which has charged 1,356 times so far without a problem.
|Thread: Covid AGM|
The BMFA's own AGM is via Zoom on 14 Nov, your Club Secretary should have been sent the details.
My own Club's AGM is by email, like others essentially rolling things over this year.
