Do you have spektrum plug-in module for Futaba? otherwise, I don't think you can bind 300X with your Futaba 9C.

Jaz,

Thanks! The bird is smooth as butter in flight. A real treat to fly. I flew a few more packs this evening, working on fine-tuning my normal & idle-up settings to where I want them, and just slow-flying around the yard. Anyone who has mastered sport-flying with the mCP X (especially b/l conversions) should have no trouble hovering & slow-flying the 300X - especially on reduced rates.

This is what the BSR should have been! If I would have started out learning CP with the 300X instead of the BSR, I would have saved myself nearly a year of trying to get beyond hovering & slow-flight with that nasty-handling bird! It wasn't until I bought the mCP X that I got out of that rut. It was all due to the BSR's sloppy handling, which is pretty much the opposite of a confidence-builder for a new CP pilot. Much like trying to learn how to drive in a car that has a half-turn of play in the wheel, along with shot ball-joints & tie-rod ends! That's not the right way to learn. It is far, far better to learn to drive in a car with precise steering & predictable handling. The same is true when learning to fly RC aircraft. The 300X's rock-solid handling immediately instills confidence, which is the most important thing low-time pilots like me need in order to progress.

J_skaggs,

For me, helis are all about the convenience of flying in my yard & flying right from my deck, as I'm primarily a fixed-wing guy. If I have to go to the club field to fly, I'd rather fly fixed-wing. I'd have to go to the field to have any real fun with a 450-class bird. However, my yard is plenty big enough to wring-out the 130X, and to have some real fun with a 300-class bird. I see the 130X as a great aerobatic trainer for the 300X & larger birds, given that it behaves much like its larger brethren. I don't have to fight the idiosyncrasies of the heli while learning aerobatics, as I have to do when learning aerobatics with the mCP X.

TR,

Thanks! I assume that you already have a Spektrum DM8 module for your 9C. If not, you'll need to get one first.

Choose the 'H-1 swash' (or whatever the 1-servo swash is called in the 9C). You also need to reverse the aileron, throttle, and gyro channels. (This is different from the mCP X & 130X, which require all channels to be reversed, but don't use the gyro channel.) Other than the above, setup is no different than any other CP bird. I set the tail gyro rate to 54% in normal & 50% in idle-up. I also used a V-shaped throttle curve in idle-up, as recommended in the addendum. My 10C has 7-point curves, so the 5-point throttle & pitch curve numbers listed for Spektrum rigs aren't directly transferable to my 10C. I had to play around with the normal pitch & throttle curves a bit to get them where I want them to be. I had to do the same thing with the mCP X & 130X.

Does the 9C have 7-point curves, and do the values go from -100 to +100? If so, my curve numbers should transfer directly.

Joel -- Yes, I have the module. I use the 9C for my UMX's and my MCPX..

I have 5 point curves that go from -/+100 so it should be pretty similar!

Thanks for the help!!

I seem to recall saying similar things myself... like... all the time!

You're welcome! Glad I could be of help.

Since you have 5-point curves & a range of -100/+100, it is relatively easy to translate the DX 7/8 settings from the manual. For instance, 80% on Spektrum's 0-100 pitch scale equates to +60 on our -100/+100 pitch scale, while 20% on Spektrum equates to - 60 on our rigs:
0.8 x 200 = 160; 160 - 100 = 60
0.2 x 200 = 40; 40 - 100 = -60

Packs are charged. Time to work on my normal mode curves so that I don't have a big surprise when switching to idle-up. (I really hate surprises when switching to idle-up! ) I was working on that last evening, but the biting flies were so thick that I couldn't finish the job.

11:15 AM, and it's already 94 F. It's supposed to hit 100+ today. Ugh! Guess I'll also be doing a heat-test whether I want to or not! Wind is 11-19 MPH, so I'll also be finding out how the bird handles a stiff breeze. I'll shoot some 'hovering & slow-flying in the wind' video.

A little less flight times I would assume. Have used nanos in my mcp x but wasn't impressed with weight and performance.

Huh, I loved the Nanotech 300's in my M5 MCPX.. That's all I flew after trying a few.
Once I went to TA915 and HP06V2 I had to get the Hyp 550's though.

Nano's have always been hit or miss. They can go from either really great to 10 flights and no power..depends on the batch.

IH,

The specs are listed on the battery page:

W: 35mm
H: 24mm
L: 68mm
Weight: 114g

My scale doesn't go high enough to weigh the pack, but my measured dimensions are:

W: 35mm
H: 23mm
L: 69mm

I have a couple of Outrage NRG 1300 mAh 35c discharge/5c charge packs from my old BSR that fit the 300X. They seem to be working well in the 300X, but then I'm not flying this bird aggressively enough to assess battery performance.
They're now over 3 years old, but they have not puffed at all, and they still seem to perform well in other high-current apps. Performance & longevity seem to be on-par with quality packs such as Hyperion & Thunder Power. I see that they are still available from HeliDirect. However, I can no longer find any mention of Outrage LiPos on the Outrage RC website, and I've seen a number of questions posted on HF regarding the status of Outrage NRG LiPos - so I'm not sure what's up. (I hope the ones on HeliDirect are not old-stock. That would be scary, given than LiPos start to degrade immediately after they are made & continue to degrade while sitting on the shelf.) I just sent Outrage RC a message regarding the status of their NRG line. Hopefully, they will respond in a timely fashion.

W: 35mm
H: 23mm
L: 72mm
Weight: 118g

For sport/endurance flying, I'd like to try Hyperion's LG345-1600-3S 45c pack. However, at 89mm, it might be too long to fit under the canopy. For performance, I'd like to try Thunder Power's TP1300-3SPP65. However, it may also be too long, at 98mm.

BTW - I got rid of the EC3 connector & converted the bird to Deans to match the rest of my non-UM electric fleet.

Shows you how good my search skill are lately
Ill order a few of the nano's then and see what kind of luck I have at the HK slot machine.

Thanks
