The new transistor on the board can cope with increased current. All batteries voltage is applied to your mag now. If you want to achieve maximum RPM, just move the jumper to the position closer to the mag connector. If you tend to use 20-24 V batteries and a mag requiring much current, you may need to mount a heatsink on the part, there is enough space for it.ģ. If your batteries voltage is above 20 volts please check the linear regulator temperature after 3-5 minutes of intense shooting. The actual RPM you'll be able to achieve depends on your mag type and condition, let's wait for users feedback. This mode is safe for Blackbird-type magazines. If your batteries voltage exceeds 17.5 volts and the jumper is in the position closer to the display, mag voltage is limited to 15 volts.
The actual RPM you'll be able to achieve in this mode depends on your batteries voltage.Ģ. This means the mag voltage regulator is bypassed and all batteries voltage is applied to mag motor. If your batteries voltage is below 17.5 volts you can put the jumper in the position closer to the mag connector (there are two positions available, see the photo below). As for the mag, you have three options now:ġ. The processor and LED display draw only 5-12 mA so a simple linear voltage regulator can supply them with all they need. This would mean less efficient and more bulky DC-DC converter.

Now, achieving higher ROFs requires further voltage increase, plus higher voltage applied to the mag means the converter has to supply more current. But then I had to increase its output voltage from 9 to 14 volts (so in-out difference was reduced). DC-DC converters are efficient when there is significant difference between input and output voltages. Originally, it was implemented because we needed to lower mag voltage from 24 to 9 volts with minimum losses. Here's the ideology behind the design changes: let's say good bye to DC-DC converter, we don't need it any more. It's $10 cheaper (no need for DC-DC converter). Better transistor in mag control circuit.ĥ. Mag voltage is controlled with a jumper (see below).ģ. What it inherits from the previous design:Ģ. Please welcome the board ver.3 (Sergey's board - 2).

Although we are not currently able to accept your proposal for a new record, we will keep your details on file and will let you know if our decision changes in the near future.įor information on what makes a record, we would advise before submitting an application to visit. While we certainly do not underestimate your proposal, we think that it is a little too specialised for a body of reference as general as Guinness World Records. Unfortunately, after thoroughly reviewing your application with members of our research team, we are afraid to say that we cannot accept your proposal as a Guinness World Records title. Thank you for sending us the details of your proposed record attempt for 'Fastest Fully Automatic BB Gun'. Unfortunately it was not good news, but did not discount our achievement. I just want to remind everyone I hit 4K with the Bumblebee you sold me. Replacing the breech seal with one of the below is all you'll need to do to restore its normal velocity. The Canadian ones come with an amber colored design to allow some air to escape thereby reducing muzzle velocity to the legal limit. The only difference between the Canadian guns is the breech seal. Unfortunately, it did not come with advertised full auto chip, so if you order from them, I'd call and ask them to test fire it first to confirm or order elsewhere. You'll likely have to pay an additional $30 or so in duty as well. Note all prices are in Canadian dollars, so the actual cost in US dollars is less. If you have success please post so others can join the fun. At one point your could still buy them from Canada.
