Hey sissy, if you were to kindly send me a Hella hele, I would not open the box and put it on EBay.
I don't like helis. Maybe it's because I can't fly them.

Do I wait for HK or should I get a couple from H lobby and which one if I do?

I'll go ya one better. AFA replacing the 6mm original, I wouldn't want theirs. In my crash (which wasn't very hard), that one splintered in about 6 places right dead in the middle, & the glue holding my 4mm insert broke it completely free, while it emerged unscathed. Saying that, I'd look for a 6mm with thicker wall, which would mean our 'normal' 4mm insert might not fit inside. Shop around, note the ID of the 6mm outer, & select an inner rod with an OD that'll fit. Makes finding a bit more iffy, but do whatcha can. Keep in mind you might have to go with inch sizes instead of metric. (Not that there's anything wrong with that!)

Meanwhile, here's a couple places you might check out:

My guess is, more'n likely ya prolly couldn't figger out how to open the box, either.

This is the tube I used inside the 6mm wing spar to reinforce it:

Hey guys;
I'm attempting to run some efficiency graphs on the stock 2620-1900 motor. Some of the input data I used are questionable, so let me ask: Here's the info requested:

Enter Kv <> got that, at 1900
Enter Io* [?]
Enter Rm** [?]
Enter Voltage 11.1 -?-Presuming this refers to the battery rating??
Enter Weight*** (g)

*Io = Noload Current of the Motor, derived from running a motor WOT without a prop at varying voltages. Io can be expressed with an associated Voltage and should be. [Presuming this represented by next input line, 'Enter Voltage']

**Rm = Resistance value of the motor, derived from the guage of wire used

*** 'Weight' would logically seem to be the AUW of the plane - I've used 700g as an average with 2200mAh LiPo. The reason I question here is, I've seen some notes (thread related to this tool's use) indicating this is the weight of the motor. I don't see how that could be applicable in calculating 'efficiency', unless it's figuring in a load compensator for spinning the outrunner casing, which this tool isn't dedicated to figuring, so....????? Thoughts?

Here's the tool URL if you want to give it a run:
http://www.peakeff.com/GraphKIR.aspx...=test2620-1900

And here's the initial input figures I used just to try it out:
Enter Kv 1900
Enter Io 0.5 [?]
Enter Rm 0.5 [?]
Enter Voltage 11.1
Enter Weight (g) 700
---And, selected 'Show APC Props'
Results indicate some interesting propositions for other-than 5x3 & 6x4 props!
I want to get more accurate input for the Io & Rm - but the above numbers produced theoretical (graphed) speed pretty close to what I clocked the Bix at on radar.

Anybody know 'righteous' numbers for this? Thoughts?
TIA!

Nah. No problem there as SHE normaly gets there first to see 'What have you bought now'.
As for helos... When my foam models get damaged (which is not very often) it normaly is a quick fix, even on the field.
I have seen some very expensive Helos bite the dust, and the bits go into a plastic bag as a bin job.

HI Jam1e, could you please tell me how you install the Turnigy 2835-3900KV, the stock motor is an outrunner I think, and the other is an inrunner,,,,,,
Im flying my Bixler with the stock motor and 6x4 APC, but due Im entering into FPV, more power is a must? should I need to separate the frames of the plane?
Please Help me,,,,
thanks

It will do a SOGATO. It will also go vertical for a while and gets me to a gliding height of about 400 ft in about 20 seconds.
I then glide around thermal hunting or glide back down and then power up for height yet again.
As for the duration of my flying times... I have yet to run the 2200 3s down in my flights.
Also no gyros are harmed in my flying as I don't use them.
+1 on the motor. But I might be trying gyros just for fun.

SH read page 1 (motor specs) you will see that

No load current is quoted as 1.5A at 11.1V and
Internal resistance is 0.04 Ohms

Come on man, Flypoppa will be laughing his head off

Don't ever try a heli! Not even one of those cheap ifra-red controlled counter rotating things. They are addictive. I made that mistake and now I have a Blade MSR (fixed pitch), and and an MCPx (collective pitch) and am just waiting until the MSRx (flybarless MSR) is available so I can get one of those. The MSRs are great for the winter in the living room. Flybarless is more controllable. Collective pitch allows inverted flight but is more suited to outdoor use due to much higher rotor speed.

Fair warning. Don't do it!

Too late Gord. I already have a couple of those IR little ones that were bought for me. I also have a 'UFO' thing that just goes up and down and I can get it to hover.
Not addictive for me luckily.

Laughing.... That is doing my head in so all I can do is laugh.
Some how I don't think that I need to know all that stuff.
I just stick a recommended and tried prop on, and if it flys, then that's it.
Good on here ain't it?

Great ozair, what about the incidence of the motor, some advise on that?
Thanks for your patience,,,
