i86 Lite costs $1 less, removes features

i86 Lite costs $1 less, removes features

June 28, 2012 10:55 | By | Add a Comment

Hobbyking is now selling the i86 Lite – in essence a rebranded Eagle N6 V2. The improvements are a slightly lower price and the fact that the microcontroller is now getting its clock signal from a crystal oscillator, which provides for a more stable clock frequency.

And how does this improve the flight performance? Quite frankly, not at all. It’s a more clean design from an electronic engineering point of view, but out on the airfield it doesn’t matter. The regular i86 has more than adequate flight stability and whether the clock frequency is exact down to the second comma is irrelevant for that.

On the negative side, the i86 Lite loses support for fixed wing aircraft, so you cannot use it as a cheap and powerful 3-axis airplane gyro anymore.

Our verdict: Skip the i86 Lite, it’s not easier to use, doesn’t offer more stability, but actually has less functionality at the marginal benefit of a more stable CPU clock. Get the regular i86, it’s the simplest and cheapest way to get flying with a multirotor craft today. You set the DIP switches for your craft, dial the pots so it doesn’t wiggle, and you’re good to go. Check our i86 Flight Controller Review for all the details on this board.

KK 2 Multicopter controller released: $30 at HK

Now that is a pleasant surprise: The KK2 controller, exclusively designed for HobbyKing by Rolf Bakke, is now on sale at HobbyKing for 30 bucks. For a controller with accelerometers this is a steal. The microcontroller is a Mega324PA, so not exactly a powerhouse, but we’ll see how this new controller stacks up compared to the MultiWii and Rabbit boards out there in our upcoming review.

Holybro KK Board, yet another KK clone

Holybro KK Board, yet another KK clone

June 18, 2012 12:13 | By | Add a Comment

Yo Bro! It’s the Holybro KK Multicopter Flight Controller, the latest version of the aging controller board design by Rolf “CapteinKUK” Bakke, featuring… the same old Murata gyros? The same “latest version 5.5” PCB that has been sold for well over a year now?

Look, the KK boards were the mainstay of the multicopter revolution, but in 2012 there’s simply no valid reason for getting one of these anymore. The “Bro” version sold at GoodLuckBuy is relatively cheap at $20 and comes in several pre-programmed versions for X, Y, Single-, Dual-, Hex-, etc. -copter… but why get this when you can get the better Eagle N6 / i86 for the same money? Not only is the i86 smaller and lets you select airframe type with simple DIP switches, but the STM 3D gyro is simply generations ahead of the aging Murata gyros on the KK board.

Hobbyking sells their KK board by pitching those gyros as being “high end” – but in fact the ENC type Murata gyros are not even being produced in volume anymore, they have been phased out back in 2008, and Hobbykings own HK401 helicopter gyro ditched the aging Murata ENC sensor for a new gyro sensor in 2011. It is said that these gyros are less vibration sensitive than SMD gyros, but we tested the i86 with props that were not quite balanced, and the SMD-gyro powered board still flew as stable as any gyro-only board.

 

Crius MultiWii Lite Review

Crius MultiWii Lite Review

June 15, 2012 0:16 | By | 8 Comments

MultiWii is perhaps one of the most well known Open Source multicopter projects. All its hardware and software is open source. Originally based on sensors taken from gutted Nintendo Wii controllers, this project has come a long way – and these days you don’t need to cannibalize a WiiMote or Nunchuk controller anymore. You get a board like the Crius in this review, and you’re set. But how well does it work and how difficult is it to set up? That’s what we’re looking into in this review.

FreeFlight controller discontinued?

FreeFlight controller discontinued?

June 11, 2012 19:26 | By | Add a Comment

There’s been a disturbing rumor about a discontinuation of the FreeFlight controller. First, chat logs surfaced between an user and an alleged employee of the company producing the FreeFlight boards, in which the employee cited legal tension between the manufacturer of the Rabbit flight controller and FreeFlight as the reason for them stopping both the design of the upcoming GPS module, as well as ceasing to manufacture the FreeFlight controller itself. According to these chat logs, the company behind FreeFlight is now working on a new, completely integrated controller that combines all sensors and GPS onto a single PCB.

These are all rumors of course, and impossible to verify.

However, we received the following letter from GoodLuckBuy.com in one of our recent shipments, which incidentally contained both a MultiWii SE and a KK5.5 flight controller (as well as two fitting USB FTDI interfaces) instead of the FreeFlight controller:

 

Thank you for buying at Goodluckbuy.com!
You may notice that we have sent both MWC SE and KK 5.5 board with your copter, instead of FF board.
The reason is that we recently changed the control board of the quad-copters you bought; also the website descriptions have been changed too. But we also considered that our customers may have not noticed this minor change, therefore we send your order by express with no extra cost, also with two control boards that may give you more options. Hope you would like it.
We also sent our gifts with your order besides the extra control board, to thank you for being a customer of GLB!
Hope to see you soon!

Regards,
The GLB team

P/S: Our FF board supplier quits their business, so FF board would not be listed on our website now!

 

We have no information whether this means no FF boards from one supplier, or no FF boards at all. There’s also no confirmation about possible legal action from another controller manufacturer. All we know for certain is that there are no FF boards available from GoodLuckBuy in the forseeable future, however their way to deal with this situation was commendable!

Hubsan Spyhawk gets updates

Hubsan Spyhawk gets updates

June 10, 2012 17:34 | By | Add a Comment

While we’re still waiting for our review unit of the Hubsan Spyhawk, it looks like they took some of the criticism by RCModelReviews to heart and made some changes:

  1. Recording can now be toggled remotely with the ENTER key on the transmitter
  2. Stabilizer gyros can now be switched on and off remotely via the EXIT key on the transmitter
  3. Elevator control surface has been enlarged
  4. Cooling vent added to canopy
  5. CG is now marked on the underside of the wings
  6. New servos, with allegedly better performance and no overheating

Apparently all new shipments will come with these improvements.

Alishanmao posted a nice little 3-part video on youtube about the new Spyhawk.

The Q450 frame sold by HobbyKing is a sturdy, cheap frame with a simple construction that can take quite a beating. It’s being marketed as the RM450 V1 by RcTimer for a few bucks more, and both are completely identical. But how does it fare in the air?

Hobbyking i86 / Eagle N6 Multi-Rotor Control Board Review

Hobbyking i86 / Eagle N6 Multi-Rotor Control Board Review

June 7, 2012 22:34 | By | 10 Comments

At a mere $20, the Hobbyking i86 is a cheap clone of the Eagle N6 V1 board. Unlike KK, MultiWii and most other boards it does not require the user to flash a firmware in order to fly, instead the airframe type can be set via DIP switches. It’s simple, it’s cheap and it’s small, but is it worth saving money on the controller board?

SkyRC GPS logger measures your speed, slowly…

SkyRC GPS logger measures your speed, slowly…

June 2, 2012 14:43 | By | Add a Comment

The SkyRC GSM-010 is a GPS receiver/logger with an integrated display for current and maximum speed and altitude, trip length, time etc. – it was designed for RC modelers, or so SkyRC claims, allowing pretty much everyone to drop this 40 gram heavy unit into their plane to measure the maximum speed over ground.

In essence this is just a GPS datalogger with a display. The model name (“GSM”) doesn’t hint at a built-in GSM modem, it’s just there because… that’s what they call it. There’s 4MB of data storage, and a USB port so you can download the recorded route to your laptop for display in Google Earth. A miniscule 200mAh LiPo inside gives you 150 minutes of GPS tracking time. You won’t be able to put this into your pylon racer any time soon, as it’s definitely on the bulky side:

The GPS has a 1Hz maximum update rate, which can be slowed down even further using the supplied PC software – you know, just in case you want your top speed measurements to become even less meaningful.

Honestly it’s difficult to see this being useful for anyone but an RC beginner with a mild curiosity for how fast their model can go. The 1Hz GPS receiver pretty much disqualifies this for high-speed planes as you’ll have to sustain your top speed for several seconds before this unit will provide even a half-accurate measurement, the bulky case will make it impossible to place this in cramped or slim fuselages, and the battery capacity is suboptimal as well.

You can buy this for $70 at Goodluckbuy, or you can get the Voltron mini GPS logger instead, a smaller device that weighs only 12 grams despite also having integrated display – plus it connects directly to your receiver. The Voltron is sadly restricted to 1Hz GPS updates too.

 

A much more professional GPS logger can be found by visiting SM-Modellbau (german), their GPS Logger weighs only 11 grams, has a fast 10Hz GPS and a micro SD slot, and it supports telemetry communications with Multiplex M-Link, HOTT and Jeti Duplex receivers out of the box. You can find this product in their shop here. They have a whole range of products for your logging and measurement needs, and best of all, they’re all compatible with each other.

 

The GPS Logger by SM-Modellbau is smaller, lighter, and features a high-performance 10Hz GPS receiver.

 

$19 Hobbyking i86 Multirotor Controller, an Eagle N6V1 clone?

$19 Hobbyking i86 Multirotor Controller, an Eagle N6V1 clone?

May 29, 2012 6:31 | By | Add a Comment

Hobbyking released the i86 multirotor controller yesterday, and their stock of over 100 pieces sold out in less than 12 hours. The i86 appears to be a clone of the Eagle N6 V1 controller, though with a price of $19.99 – For comparison, Goodluckbuy sells this for $49

UPDATE 2 JUNE 2012: The i86 is in stock at Hobbyking again!

This controller uses a 3-axix MEMS gyro, and is thus in the same league as the KK controller due to the lack of a separate high-resolution accelerometer. How does it compare to the KK controller, and especially the current-generation controller boards with accelerometers? Read the review here on FPVCentral to find out more!

 

The big benefit of this product, aside from the price, is simplicity. There is only three gain potentiometers and a dip switch to select your type of aircraft (airplane, 2/3/4/5/6-Rotors)
