Gryphon Extreme Regular - Overview and Review

Introducing the Gryphon Extreme Regulator

It comes in two flavours, with a black or silver heat sink (as pictured)
I got the black one thinking it would merge well with black plastic frames and carbon,
infact that's exactly what happened, you don't notice the regulator which is a shame
Next time I will get silver to show off this sexy piece of hardware

Why use a regulator?

A new flying style called "Smack" has emerged over the last ~5 years
It's a hard hitting, low on the deck, death defying adrenaline rush
Gennerally speaking, you need a quick and predictable swash reaction
One way to get that is by running very quick/strong CCPM servos
and even doing so at higher than normal voltages
but numerous other electrical devices on the heli can't take these higher voltages
most notably these are the throttle and tail servos,
but there are others (some Gyro's, governors, on board glow, etc)

Another reason to use a regulator is simply to ensure a robust power supply to the CCPM servos
The standard RX on/off switch and wiring that is intended for R/C planes is not heavy duty
Our helicopters often have 3 * 10kg servos on the swash, they should have a robust power supply
The regulator gets it's battery power via a thick input wire and a deans plug
The CCPM servos plug directly into the regulator to obtain amps from a heavy duty device

So the idea is to deliver a higher voltage & current (10amps) to the CCPM servos
(the Gryphon can do 5.2, 6.0, 6.8, 7.2 and bypass)
and a standard 5.2v & 5 amps to the RX, throttle, Gyro, Tail Servo, etc
You can use this regulator with 5 to 8 cell NiCad/NiMH or 2 cell LiIon/LiFe/LiPo

The Gryphon wiring diagram is very clear and easy to follow

There are two blue LED's to show the independant low and high voltage circuits are working
There is a red LED and buzzer to warn you when the battery is low on voltage

You can also get an external low battery LED - you mount it in a visible position on the frame
It has a blue LED to show working and a large ultra bright red LED to show low voltage - you would see it in flight I think!

The Gryphon comes with a electronic safety switch
which you remotely mount on a the frames in an easy to access position
It has a 3mm hole, you use a frame cap screwn to locate it

So let's get into some bench testing

The first thing I always test with regulators is that they must go into bypass mode
when the battery voltage falls below the regulated voltage setting
(We don't want the regulator to turn off!)
The gryphon stayed on and passed all the voltage straight through right down to 2.8v - passed
(my PSU can't go lower than that - but at that level some RX's turn off anyway)

The next test was voltage stability
No change in regulated voltage between sitting idle and drawing 5 amps - passed

So what sort of average current do our helicopters draw?
My 50/600 nitro draws about 300ma per nine minute flight
That works out at an average of 2 amps
No doubt there will be higher peek current events, but they are very short (less than 2 seconds)

The next test is a current draw and thermal cutout test
Some regulators get too hot and burn out, some have thermal protection and shut down early
(I would rather the regulator did not go into thermal shut down,
protecting a $120 regulator and crashing a $1500~$3000 heli is stupid)
The standard test I do here is a constant 3 amp current draw for 13 minutes
That's 50% more current than normal and not many nitro's fly longer than 13 minutes
This test is done with no airflow over the heat sink, ambient temperature was 22 degrees
The regulator's heat sink steadily increased in temperature over the 13 minutes finally reaching 70 degrees
It only exceed 60 degrees at th 9 minute mark
No thermal cut out - pass
Probably need to get it hotter but other regulators can't pass this simple test
and my gryphon is only ever luke warm on landing (not 70 degrees!)
so we are well within sensible safety margins
If you can ensure some airflow over the heat sink you are even safer
The body of the regulator never exceeded 38 degrees
The discharger and the PSU both had their fans going half way through this test,
yet the Gryphon just took it in it's stride

Canberra Chopfest 2012 is coming up!

Just under 3 weeks to go until the the most awesome RC Helicopter funfly in the Nation's Capital takes place.

Some of the boys from Sydney, Melbourne, Central Coast, Brisbane and a few other places are making their way over to the Namadgi club's Williamsdale field on the 29th and 30th of September for the event, it should be loads of fun!

Hope to see you there.

Edge Shipment just in - New 353mm Flybarless Blades now up!

We've just gone through and processed our recent shipment of Edge Rotorblades this evening. Various things back in stock or in low quantities have been topped up. A new addition to the website this evening is the all new 353mm FBL blades, for your Rave 450, Stretched Mini-Proti or Trex perhaps? I know I've been hustling the team at Edge to make these for quite some time, so this to me is like an early Christmas present! If my poor Rave wasn't in a mangled state, I'd crack these out now for some urban 3D action!

You will find these new 353 blades under the Blades section under 450's or Edge as usual... or if you want to browse ALL OUR EDGE products in one page... well, click that magical text just over to your left there.

I've still got more shipments to process, will save them for tomorrow :)

Byron Fuels shipment has arrived!

Hey everyone, I just thought you might be interested to know that we received a shipment of Byron fuels today. Its our first shipment that has come to us directly from the United States, so it was all very exciting going through my first Sea Freight importing adventure. It was a little trickier than I expected it would be, that's for sure.

I gotta give out some huge props to Martin and his wife Rachel for their (more her's than his, but whatever) massive help with the customs importation paperwork. Without their help, I'd probably still be filling in forms!

So what did we get in this shipment?

- Rotor Rage 30%
- Rotor Rage 15%
- ProDriver 2500 25%
- Race 1600 16% (this is the 12% oil mix used by old mate)

All of the above except the Race 1600 are existing blends we carry. The 1600 should be making its way to a variety of hobby stores in Australia over the next week or so. If you need help finding a local source for fuel, please send me an email and I'll see what we can do for you.

Over and out for now.

Out of Office notification: GONE TO IRCHA BRO!

This is an advance warning, we don't actually leave until the 13th of August....

Jeremy and I will be out of the country attending the IRCHA 2012 Jamboree all the way over in Muncie, IN in the US of A. We'll be running around being idiots having a grand ol' time. We're gone from the 13th, and landing back in the country on the 24th. Epic sleeping action on the 25th and 26th, and back to the daily grind on the 27th.

While we're away, our dearest Shannon will still be sending out orders to the best of her capacity. We would like to outline the following expectations during this two week trip:

- Orders should still go out as usual, please don't rage if we don't get them out as quickly as usual. Expect minor delays in this area.
- The telephone will not get answered at all, I'll check the voicemails occasionally, but I won't be calling you back from the USA about them.
- Emails will be replied to (as I find the time and internet access whilst at the event), consider this the primary method of communication.
- No stock shipments will occur during this time, all that will wait till our return.
- Follow our Facebook page to keep up to date with our adventures. I'll do my best to pump out as much as I can through here over the course of the trip.

See you when we get back!

This week we're running some BIG special prices on the Beam 450 and 600 sized kits.

We have the Beam AvantGarde helicopter kit available for the AMAZING price of $499 plus shipping!

These are NOT a run out item, should we run out, we'll simply get some MORE in.

The ever popular Beam 450 Flybarless kit (latest version) is also up for a special price of $199 plus shipping as well.

Perhaps you had a massive stack and need a new airframe? maybe you just want to get a heap of spares for an excellent price, either way you want it, you can have it today!

Prices are as marked, and are available now... no need for silly coupons or special user based discounts, its available to everyone.

Over the past few months we have been building ourselves a Beam AvantGarde, we've enjoyed the build and hope to be unveiling the finished product as soon as it starts to get warmer here in Canberra. The expectation is to have something ready at the end of this month, or early September.... in any case, when its ready, we'll show you here ;)


You shoulda bought a....

I don't need to complete this sentence.

Speaking of which - PHAT shipment of Gaui stuff arrived yesterday. Got the 500X's, 330's, all their spare parts, some Formula canopies, a wad of parts for the X5 and X7 and other basic staples. Its gonna be another fiendish week of data entry, so watch this space!

Big Congratulations to Marco Rebelo and Vasko Serovski!

What can we say really?

The team here are all very proud of both of these gentlemen for making it all the way over to Venlo, Netherlands to compete in the annual 3D Masters competition. In all honesty, we were proud they went over to compete - but to come back having taken the 1st place in experts division is just totally amazing. I sat up to 2:30am watching the RCMedien live stream (which was just unreal, it was almost like we were there!) shouting away at the computer monitor like it was the greatest moment in Australian history (let's be honest here, it probably was).

The competition in this event was just top notch, there was some amazing flights being done by pilots from across the world. Notable mentions go to Kyle Dahl, Eitan Goldstin, Asaf Aloush, Luca Pescante, and Dunkian Bossion (among many others!) for their jaw dropping flights that I watched over the course of the weekend.

We wish Marco and Vas a safe return to Sydney. Take a couple weeks rest, then start preparing for next years event as a competitor in the Masters class ;)

SwitchGlo Distribution

I've probably been saying this too frequently lately - no matter!

We've been appointed the distributors for SwitchGlo's range of products, namely the SwitchGlo and PushGlo. The range has now been extended to include each Pigtail variant that's available (there's three different types didya know?).

You'll find all their products under our SwitchGlo section or under Electronics --> Glow Ignition

All the goodies are in stock already, wholesale enquiries welcome as usual.

Long weekend - totally closed here bro!

I write this with my phone from the South Coast while watching an army of elderly getting down at a Jazz festival. Its pretty amazing.

Anyhoo, this coming Monday is a public holiday for us - and we are all away for it. Will be back on Tuesday to start sending out orders again.

Thank you come again!
