The airsoft electronic gun (AEG) is really a fairly simple mechanical device with very little electronics to it. Using mechanical means, it can provide three selector modes: safe, semi-auto, and full-auto. But the most popular airsoft gun in the United States is the M4 (AR15 replica), which is used heavily in the U.S. military. The real M4 fires in three shot burst, a feature that is not easy to achieve in a mechanical airsoft gun with simple electronics.
That's where Burst Wizard King Kong Super 2 comes into the picture. The Burst Wizard King Kong Super 2 not only provides custom burst features, but acts as a MOSFET, LiPO and LiFePO battery protection, a resettable fuse, and other features that only sophisticated electronics can provide to an AEG. Before we go into each of the features in detail, let's take a look at the Burst Wizard King Kong Super 2.
We actually purchased the Burst Wizard King Kong Super 2 in order to provide semi-auto mode to an AEG that only has full-auto mode. See our Fixing Your AEG Broken Trigger Post article.
The Burst Wizard King Kong Super 2 came in a yellow packing envelope. Luckily, I live in the same vicinity as its vendor headquarter, so I received the product a day after it shipped. Inside the yellow packing envelop, the content is stored inside a ziplock bag (see photo below).
The photo below shows the ziplock bag content; the Burst Wizard King Kong Super 2, two red wires for permanently installing the product in your AEG (optional), two shrink wrap tubes, and instruction sheet.
The newer Burst Wizard King Kong Super 2 is actually smaller than the Burst Wizard King Kong Elite. There is a size comparison photo on the vendor web site. The Burst Wizard King Kong Super 2 is the size of two dimes place side by side. The entire unit is shrink wrapped in a black tube with a label (see photo below).
There are two ways to install the Burst Wizard King Kong Super 2. One, it's a plug-and-play unit where you plug it into the AEG, where you'd normally plug in your battery (see photo below). Then you plug the battery into the Burst Wizard King Kong Super 2. One nice feature of the plug-and-play method is that you can move the unit from one AEG to another quickly. The other way is similar to the first way, except you also permanently solder the Burst Wizard King Kong Super 2, with the supplied wires, to the trigger connector. In this second way, you can't move the Burst Wizard King Kong Super 2 from one AEG to another. But it provides a few important features that is unavailable in the plug-and-play manner.
Burst Wizard King Kong Super 2 comes in two versions: 1) a Deans connector version; and 2) a mini-Tamiya version. We ordered the mini-Tamiya version. The instruction sheet says to plug the Burst Wizard King Kong Super 2 into the AEG first, and then plug the battery into the Burst Wizard King Kong Super 2. It doesn't warn or say what would happen if you do it in reverse. My guess is that it doesn't hurt because the trigger contact is open anyways. But we haven't actually tried that.
Five seconds after plugging the battery into the Burst Wizard King Kong Super 2 unit, the LED stays on to let you know that the unit is ready for operation. If you squeeze the trigger any time within the five seconds after plugging in the battery, the Burst Wizard King Kong Super 2 goes into programming mode.
The Burst Wizard King Kong Super 2 (BWKKS2) is a newer version of the Burst Wizard King Kong Elite (BWKKE). Moving to the BWKKS2 is a huge improvement. Let's examine the improvements.
While the BWKKE support LiPO battery, the BWKKS2 supports both LiPO and the newer/safer LiFePO batteries. But the biggest improvement that BWKKS2 provides over the BWKKE is the resettable fuse. In fact, I have burnt out the BWKKE before. BWKKS2 eliminates that possibility, because it shuts down. Once you have unplugged the battery, it resets itself.
Burst Wizard King Kong Super 2 is compatible with batteries ranging from 7.2 volts to 14.8 volts. You can use NiCd, NiMH, LiPO, or LiFePO with Burst Wizard King Kong Super 2. In fact, the Burst Wizard King Kong Super 2 acts as a low-voltage warning device and shut-off device, if you turn on the LiPO/LiFePO feature. When the warning and shut-off feature is turned on, Burst Wizard King Kong Super 2 will beep to notify you of low voltage condition. With the Burst Wizard King Kong Super 2, you won't have to buy a separate LiPO/LiFePO battery warning device.
With the Burst Wizard King Kong Super 2, simply plugging the unit inline with the battery into your gun will provide most of the features available. Only a few features requires you to hard-wire the unit into your gun.
The most basic feature is the burst fire. You can configure the unit to fire in bursts when your AEG is in full-auto mode. The unit will automatically count the number of burst and stop firing when its done. If you continue to hold the trigger, the unit will automatically fire in full-auto mode. The trigger hold delay defaults to 0.6 seconds, but you can program the delay at 0.2 second intervals. Of course, Burst Wizard King Kong Super 2 lets you turn off full-auto altogether. Or it lets you enable full-auto only with no burst fire control.
Another feature is the "Sniper Delay". When you turn on this feature, the unit automatically set an interval after you fire the previous shot where you cannot fire another shot. Your AEG can emulate a bolt-action sniper rifle using this method. It's a good way for you to see if you like the sniper play style.
If you like to use real cap magazines, you'll like the "Magazine Change Delay" feature. You program the number of rounds of your magazine (between 1 and 99). After you fire that many rounds, the Burst Wizard King Kong Super 2 unit automatically stops firing to signify running out of bullets, forcing you to change mags. The delay is programmable at 1 second intervals.
Do you want to know how fast your AEG is firing? Burst Wizard King Kong Super 2 can tell you with its "Announce ROF" feature. Once you enter that mode, switch to full-auto mode and hold down the trigger. After firing 11 rounds, Burst Wizard King Kong Super 2 will beep and blink to announce your gun's rate-of-fire (ROF). Keep in mind you should shoot real BB's--rather than just dry-firing--to get an accurate number.
There are several features that Burst Wizard King Kong Super 2 supports, but require you to have some mechanical and electrical skills. You basically need to take the gun apart, and solder a piece of wire to the trigger contact in the gearbox and to the Burst Wizard King Kong Super 2.
One of the most interesting feature in this regard is the "Tap Burst" feature. When this feature is turned on, the AEG will fire all burst rounds even when you have released the trigger pull.
There are many other burst control units on the market. However, most other units I see costs $100 and up. Burst Wizard King Kong Super 2 is priced at $40. The only other units I seen at this price is the Burst Avocado. However, I couldn't find a place to order the Burst Avocado anywhere in the U.S. Other more expensive units also seem to have some availability issues.
So far, it seems that you can easily order the Burst Wizard King Kong Super 2 from its AEG Wizard vendor web site. It's also available on Airsoft GI, AirSplat, and Amazon.
During our review of Burst Wizard King Kong Elite, it smoked and failed. We suspected a defective unit and contacted the vendor during the day. An hour later the vendor contacted us and asked us to ship the defective unit back for a replacement. Since we were in the same vicinity, we received the replacement unit the next day. The customer service seems to be extremely prompt and reliable.
At the time, the newer Burst Wizard King Kong Super 2 unit is out on the market. So we received the Burst Wizard King Kong Super 2 for this review.
We originally had the Burst Wizard King Kong Elite. Then we got the Burst Wizard King Kong Super 2. You can see our review of the original product here: Burst Wizard King Kong Elite Review.
Last weekend, I went to an indoor CQB airsoft field with the APS ASR106 Mini Patriot M4, which I installed the Burst Wizard King Kong Super 2 into. The Burst Wizard King Kong Super 2 was programmed for single round burst.
Half way into the first game on the field, the gun stopped firing. After sitting out to mess with the gun in the second game, I found that the gun fires without the Burst Wizard King Kong Super 2. Apparently, the battery does not have enough power to drive the gearbox after Burst Wizard King Kong Super 2 had pulled down its voltage.
My APS ASR106 Mini Patriot M4 has always been a battery hog; only my 9.6v NiMH battery has been able to drive it. Nothing less will drive it for too long. Sadly, the Burst Wizard King Kong Super 2 draws enough power to drop the voltage beneath the threshold.
I have, since then, gotten a 9.9V LiFePO battery pack for this gun. It works beautifully with the King Kong Super 2 in this gun. I have used the gun--set up for 3-shot burst--during a full day tactical training. Then I used it for a full night at an indoor airsoft field. It works great both times.
So in your application, you'd probably need to go one battery grade up to use the Burst Wizard King Kong Super 2. For example, if you are using a 7.2v battery now, you may need to move up to a 8.4v battery.
