Thread: Motor Ident?
05/07/2020 12:20:02

Hi Roger,

I probably wasn’t that far behind you, I’d already guessed that the unloaded revs were in the 17,000 region; 17,285 to be precise. But that in turn is making me more than a trifle suspicious too. Those current consumption figures do tend to stand out from the crowd a little, 52 amps to drive a 9 x 6 on 3S?? Put that lump in your model and you’d flatten the battery in less than three and half minutes! ….And just how far is 52A out of spec. anyway? Can we now barbecue some sausages on the ESC?

On the face of it, it appears you are getting an approximate 1,200rpm gain for a 22 ampere current flow increase. Based on this, to get to the sort of figures I might want to be looking at I think I might need to be looking for something like a 7 x 2 prop…

Do you by chance have a link to that motor please? I can find the 1,000 and 1,250 ok but not the 1,450. Perhaps it’s gone into hiding, if so is there a reason for this I ask myself?

Carry on dabbling, Roger, it’s all getting nicely interesting…

03/07/2020 18:23:07

There are many cheap copies Ashley, so don't bother with those

Look at the approved dealers like ALS Hobbies and Inwood Models

Less costly are Orange and Lemon DSMX receivers, look at RapidRC

The AR9020 has 2 banks of pins arranged both ways Tosh

It is easier to show one bank of pins from an AR6210 that is clearer, illustrating all the minus pins align to the

outer wall of the casing. The chamfer and pin out is the same On your rx.

The line drawing shows the AR9020 alignment minus to the top of the case in the top row

Minus to the bottom of the case in the bottom row

Thread: Dihedral
02/07/2020 20:35:17

Personally, I would choose to fly a flat wing, as Cubs are a favourite.

But you do lose the " self righting " properties that the dihedral gives, and the extra stability.

Flying without dihedra! comes naturally after a while that whenever you roll the wings, you need to roll back again for straight and level

It is marked up Tosh

Below AUX 1

Minus, plus and signal

02/07/2020 14:21:22

Always been a problem Tosh, since day one.

The only plugs that fit are Spektrum servos

On my servos, I run down on sides and flats of the plugs until the shine has gone, and then they fit

As some do have the chamfer but are still tight

Dennis, I think you'll find MO1 refers to MOdel 1, not mode 1 - the picture clearly shows a mode 2 transmitter.

Probably best to wait until Andrea responds to earlier posts so we can see exactly what he's got!


Thanks for clearing that up GDB

Also, if you look at Andreas set up, he has nothing plugged into channel 1

So at least one other plug is is the wrong place

A friend of mine found this for me, and am going to be starting the same plane in about 3 months. I do have a question: I know the plane is rated for a 120 4 stroke, but I want to put in a Saito 180 gas engine. Is there any reason why I can't put that in? Thanks!!!!

Mike, Nigel has already suggested that the answer to your question is " No "

A 120 is sufficient and you should plan along those lines.

2 Things Lads

In both photos I saw of the Tx screen shows a large MO 1 which could alter the perception of the sticks control

If expecting MO 2


Here is the diagram for channels

And the MO 1 screen

Thread: Spektrum DX9 Setup- Help Needed!
01/07/2020 10:43:06

I have about 10 Questions Steve, but here are a few.

Did set the model to " Sailplane " before programming?

So you set the " Wing" and number of servos

And you set the " Tail " and number of servos?

From the manual this note

Select wing and tail types before doing any other programming

You may already have found if left at " normal " there is no flap delay

Am thinking your problem is in this " Flap System " Window

And the original set up being done before programming

Thread: Which sim - fixed wing and rotary?
01/07/2020 10:20:27

Ian, you have named both top notch flight sims

I learned to fly heli scale with Phoenix well before the model

If you can get either sim you are in the right place

Edited By Denis Watkins on 01/07/2020 10:20:53

If you look here Ian, the site has struggled before equipping Apple Mac

Flight sims are very useful so keep looking

If you ordered different colours Simon, check them carefully

As Quadcopter sets come right and left handed, that is CW and CCW

Clockwise and Counterclockwise

The correct prop blows air to the tail

Tether the model down firmly to test

Good ideas from kc Stu.

The most difficult and expensive part of the process is the plug, which you have demonstrated, you have the skill to

make Stu

Then a kindly school could run that plug through a vac former for you

Have a look on Vortex or give them a ring
