FY21AP II

ImersionRC are aware of the request for making EZUHF UK legal on 459MHz.
Aparrently it only needs tweaking, but it seems a long time coming...

Works great just testing it by tilting and rotating the plane by hand. Should really do the business in the air, I just need to remember that if the radio goes into failsafe the prop will run at 70% throttle  :o  So if your setting the throttle to run in failsafe Mark make sure you disconnect one of the ESC bullet connectors to the motor, just reconnect before launch. Might help save a finger or two  :laugh:

2 wires please :)  removing one will allow the motor to enter into a spastic fit, probably not enough to hurt you with the prop, but I doubt it's good for them.

I was going to say two wires, but then I might end up reversing the motor if I plug the connectors back to front, and having the plane come back at me after launch  :laugh:

I ask them every week, the most recent time was today.  The answer is always the same..."no time right now, but soon..."

In the meantime I will be getting a handful which can be sold to amateur radio licence holders through my website www.firstpersonview.co.uk

All the best

Getting what Simon?
What needs a ham ticket?

Got one so I'm interested ;)

Good suggestion. I have read elsewhere that if you set up failsafe to triigger if the throttle reaches the throttle cut value rather than throttle zero stick position value then the radio signal has to be lost to initiate failsafe. This also means if your radio has a throttle cut button or switch you can test the RTH feature by zeroing the sticks and hitting throttle cut.

Thats a great idea, thanks!!!  ;D

Ah, gotcha

I have some articles and schematics for 459MHz Tx and Rx boards.
They are relatively old technology, but still do-able if anyone wants to homebrew some.
Too much on my plate at the moment and reality is that they would be inferior to anything that is available/in the pipeline.

Ive started using the FY21 system, and fyi, Ive had a problem in using it with a Gopro, the OSD wont overlay the information, changed cameras and it was OK. I also had a problem with switching the overlay on from the FY21 and found that initialization / reset process seems to have cured this.

Could you PDF the schematics I'm interested.

[Devonian]

I have the article in pdf form, but it's nearly 5 meg.

Can we upload 5Mb to the forum in one file?

If not, PM me an email addy and I'll email it (providing you can receive 5 meg in one go).
Last resort is I will post it on an ftp site and you can download it from there.

Also, go to Yahoo groups and sign up/subscribe to the 'HomebrewRadioControlGroup'
http://uk.groups.yahoo.com/group/HomebrewRadioControlgroup/

There are a lot of schematics are in the files area in the Yahoo group.
Also, there is some recent interest in a 'modular' 459MHz Tx/Rx.

Pete Christy - the guy who had some good input into the original 459MHz r/c gear is a member (amongst others).
He did a lot of the original UK Multiplex UHF conversions.
