Re-ordering channels in OpenTx


There are a couple of steps which I forgot to include - it's also necessary to swap the values for min/max/subtrim, curve and direction. I've summarised it all in a separate page, the extra bit is in section 9:

New Lipo information


I heard about some new batteries from Hyperion. Bought a few to test. I've attached a picture and some information. I've only static tested the Hyperion HV900 ma. It performed well over a 30 second run. If it flight tests well, it may be my battery of choice. The Thunderpower and Turnigy batteries are shown for comparison size.

Here's the info:

New Hyperion HVGraphene: 900 ma is rated at 90C weighs 78 grams, IR tested at 13, 14, 14 at 99% charge
the 1200 ma Hyperion HV Graphene is rated at 90C weighs 105 grams, IR tested at 9,9,9 at 99% charge
the Turnigy 750 normal voltage, graphene is rated at 65C weighs 81 grams, IR tested at 12, 12, 12 at 99% charge
the Thunderpower rampage 1300 ma is rated at 70C weighs 114 grams, IR tested at 18, 17, 18 at 97% charge

I used the Turnigy most of last season with good results. The new Hyperion have not been flown. The 900 ma HV Hyperion seems quite small and only comes with a 30 amp connector. I changed it out for the standard JT60. It was only slightly warm after a 30 second static run.

The Turnigy 750 and new 1200 Hyperion batteries fit snuggly in the fuse behind the canopy of the Explorer. The 900 ma Hyperion gives room to spare. It's a toasty 16 degrees here so no real world tests for awhile. Anyone else flown the new Hyperions? Also Hyperion is having a sale for 15% off and free shipping until January 5th. Sadly, I bought mine before the sale.

I recently bought four of the 900mah HV Hyperions for my Ex,, two of them puffed up after less than 5flights.
I've had extremely good experiences withTattu
3s 850mah 75c batteries. And they're very compact.

Ps edit : here's a link for the Tattus

I've been using a combination of the Tattu's from Gensace and the Dinogy's. The Dinogy 800 3S is light and thinner than the Tattu. For the Neu 707 the Dinogy 600 is perfect!!

Barry, I have 6 months experience using 6 of those Hyperion packs with my e-Xplorer and a Powerline 1025. I typed up a long-winded post but have boiled it down to this: the 90C rating on those packs is a burst rating only. The continuous rating is 40-45C. If you run them at more than 40C (i.e. 36A) you will not get very long life with them. If you use them with a 30A motor they should last longer.

Thanks to all for the information. A bit disappointing. The size of the 900 ma is a real plus. I will be running them with a 1025; ah well.

EDIT: I have heard other anecdotal information from a trusted soaring pilot that the 900 ma works fine using it for one run and switching out between rounds. I'll be testing myself when weather permits.

Hi Cary,

The new version 3.8 has the Neu 707 with the long nose pod. The pod that comes with the plane is 2.25" shorter. ESC is the Talon 35. With this combo I can shift the battery and set the CG. I made a 3x5 card with battery placement for various CG combinations. Other equipment is as follows. Futaba 3776 servos on ailerons, rudder and elevator. Futaba 3270's on Flaps. I'm using all SBus, 26 ga wire in the wing. One lead from the wing/fuselage to the receiver. Receiver is the Futaba 6303SB. This is a small 4 port receiver. Power battery is the Dinogy 600 mah 3S. I also use the Dinogy 800 and Tattu 850's. All 3S. For the larger batteries they are moved back for CG.

With the 600 packs the model weighs 40.42 ounces. With the 800 series it jumps to 41.1 ounces.

I've tried flying the plane at 131 on the CG but prefer 128. Still testing props but the GM 13x8 is working nicely. I've tried 12x7 as well. Next to test is the 12.5x6.5. This might prove to be a perfect size for this motor.

Love this plane!!!

Thanks for the info about the 707.

I just wanted another pod. After getting it I was trying to figure out why it looked different. Held it up to the stock one and discovered the difference. The longer pod is perfect for the light 707. Battery shift CG.

Honestly don't know why the plane doesn't come with the longer pod since it is designed for light motor. It can always be cut back if needed.

Thanks for all the info Darwin. I will be putting this same setup in the 'Condor' (Ultima). Gives me some data and expectations.
Thanks again.
