Hopefully should receive one of the Jumper R8 receivers on Monday so I'll do a bit of testing and see what it's like.

Apparently the Jumper R8 is now onto revision 2 that has the telemetry faults resolved so will see what we get delivered as you can never tell from China which one is going to arrive!

Also got another two of the MotiveRC ones in the order as I know they're pretty good receivers so have no problems dropping them into the parkjets.

having got my pal to repair the DJT module in one radio - it has given me breathing room to suspend ideas of buying a Multi Protocol module. As long as I can still get D8 capable Rx's - then I'm fine.

I'm a little annoyed that the excellent FrSky 4ch Rx is no longer made ... it had +1km range and was small. They just needed an extra blob of Hot Glue on the antenna solder connection to stop that antenna being pulled off.

I have to admit the D4R-ii was a cracking little receiver.
I run one in quite a few of my planes that don't need any extra channels other than a simple 4ch setup.
I've got an X6R in my big cub which seems to work ok and a few of the F82DA receivers in a few planes too as they need more channels for ailerons and elevons.
Will see what those Jumper ones perform like and if they're any good I'll get a few in stock 😉

Jumper R8 receiver turned up yesterday and it seems they've made a mess of it.
The original board had diodes fitted the wrong way around and the voltage divider for voltage monitoring inverted. The only way to get pack or Rx voltage telemetry was to connect it via a Pixhawk controller - basically the receiver is designed for use with a flight controller and not fixed wing it seems.

They released a v2 with multi-coloured connectors and a complete new board design which allowed for full telemetry including pack voltage but this seems to be now replaced with a v3 (or more like 1.5) which has the original crippled board but with the multi-coloured connectors.

So, I'll give it a go in my FT Mini Scout but I'm not holding out much hope despite how cheap it is.

The MotiveRC ones for me are looking like a much better bet but we'll see what happens with the tests...

I seem to recall from various videos and online that the Jumper was designed to work with Pixhawk. Its one of the reasons I shied away from it.

I have no call for telemetry .. but one day I will !! 

Waiting with baited breath for test results.

I like to have some flight battery telemetry for peace of mind, especially on high drain stuff like the EDF's.
I just set a low battery warning on the Tx (normally 3.2v per cell) then that tells me when I'm pushing the pack too hard and to come in.

I have the Quanum Battery telemetry units ...... but TBH - often don't use ... I forget !!

Just found another problem with the Jumper R8 - It doesn't support D16 EU LBT protocol out of the box!
So, I've had to solder onto the processor pads and flash Midelic's firmware to get that working. Quite a nice little jumper setting to select LBT mode once it was upgraded then bind as normal.  Haven't bothered with the extra wiring and fine SMD soldering to get the voltage monitor working as it's not likely to be going out as a full time receiver.
I've dropped it into my FT Scout for now and the next time it's flying weather (currently raining - again!) I'll give it a go with some range tests and real world flying conditions.
First impressions seem that it's link is ok though and has good RSSI output but I've not taken it too far away from the Tx yet to be sure of anything.

Yes, it's only a tenner for a receiver to buy one but it's worth the extra £10 for the MotiveRC one and I don't have to mess around with it.
So for me, especially if I want ease of use and a reliable D8 receiver the Motive RC is getting my vote.
I've now got 3 available to put in some planes so I'll do a bit of conversion on some of the older stuff I still have on Flysky and see what sort of comparison I can get compared to a D4R-ii.

Just rec'd my tiny plug in module for the 9X ..... once I get back from flight site visit - will be testing .... I do not expect to have great range ... in fact one thing I have forgotten .... there's no Antenna !! 

mmmmmmmm

I found my micro 4ch FrSky clone receiver last night so bound it up and put it into my Lidl glider so that's usable again.
Forgot exactly how small that receiver is!!

Still not had chance to do any flight tests with the R8 yet though - been far too windy so only managed a single flight on Sunday over local park to maiden the FT Mini Mustang but that has a D4R-ii in it (more for lack of space than anything else though!)

Still trying to figure out how to sort no antenna with the Multi Plug-in ..... all modules I use have their own antenna .. 

Actually thinking about it .. I think the 9XR has one in the handle ... but my 9x has nothing ...

On my 9xr ... it worked as listed ... with my E010 ... but could not get my 9x to bind at all ...... all using ersky9x

I have the miniature 4ch FrSky rx's and the full 8ch Motive RC .... will have to brush up on soldering skills for the 4ch ones .. 

But I think that's a snazzy idea giving you option to hard wire servos or use plugs ..

This guy seems impressed by the 4ch Rx's .... estimating by what he says .. makes me think his range check .. 125 paces ? That's about 200ft .. abt 70m ?  His flight taking his ball park chat ... reckon he was about 150m - 200m ? Maybe more ... 

Lets be honest very few of us fly outside of the 300m as we then have difficulty seeing the model ....... 

Soldering iron is going to be fired up !! 

I see some guys don't solder so pins are in same line as board ... they flip 180 and make the pins sit behind the board and plugs make a box shape of the unit keeping length short.

Sorted !! I had one control reversed - so when I put sticks to corner to select protocol on the 9x ... it wasn't eachine !! I basically compared all settings 9xr to 9x ... and there it was .............. it works !! 

Magic .... I like flying the E010 - but with the small toy controller - its not easy and you lose it often, now with 9x linked - its 1000x better and smoother. Just need to sort out how to get the Flips now ... the manual suggests Ch 6 ... so what button ??
