I didn't even check, I was going to switch the Motor out to a lower Kv anyway so I just thought I'd give it a run up with the stock Motor on 4s, seems like it will work pretty good!

Just plug right in and done very very simple.
Hey KK, would you have a photo of of the 4 pin connector and how you did that, I would like to make assy/disassy of the wings easier, they are a pain.

It almost seemed to be radio interference... Just a guess but the 5e may also be broadcasting a signal.

You will have to try the same thing with the DX7 and DX5e. Maybe that will work better.

Edit: The documentation for both transmitters says that they can be either Master or Slave.

From my experience there may be more of a prop issue than a motor issue.

Here's my story ---- I got my new Radian Pro and the motor seemed to be a low Kv, low performing motor. I was measuring 12 amps and 130 watts on a freshly charged stock 1300 mah 3-cell Lipo battery. I called HH and they said to send the motor in, so I did. They sent me a replacement motor - a stock plastic end bell Radian motor and a replacement stock Radian prop. I installed the Radian motor on my plane with the original set of Radian Pro blades and got 13 amps and 140 watts on the same freshly charged 1300 mah battery. Not much of an improvement! I then put the stock Radian prop blades on the motor and got 15.3 amps and 165 watts with the same 1300 mah battery.

After all the electrons have settled, I really wish I had kept my original metal housing Radian Pro motor and had just bought a new prop.

For those of you who are thinking about sending your low performing Radian Pro motor back to HH, I'd advise you try a new prop first.

RE: motor issue. After reading some of the posts in this thread I tested my motor draw, it was a bit over 13amps. I then flew R Pro for the first time and was satified with the climb performance. Then I replaced the prop with an EMP 10x8 prop, the same prop I use on my good old Radian. The motor draw is now about 22amps and the R Pro climbs much better, just like my original Radian. I think the "motor" problem can be cured with a prop upgrade.

I have a JR 8103 and I have used it as a master and buddy boxed a JR7202, DX5e, DX6i and a old DX6 (DSM1) as a slave, I did have to do some servo reserving on the slaves, but all of them worked good as slaves.

I tested the draw on my 2 week old radian pro, stock prop 16.2 amps, installed graupner 10x8 amps went to 21 amps, took aeronaut 10x8 off original radian and put on pro 22.1 amps.

Maybe I got the only good pro they made.

LOL, I thought about that too. Suppose I WANT another motor like this one? What then?

Although, Horizon should have plenty on hand when this whole 'replacement' scandal is over.

Matt, it's just the standard Radian replacement prop.

http://www.horizonhobby.com/Products...ProdID=PKZ1017

It costs less than $5 and your LHS may even have a set in stock.

For even better performance, you could get a Graupner 10x8 cam series prop.

Thanks for the links.
Does the graupner fold back well, or does it stick out in the airflow?
