About to buy my first Li-Po battery charger/conditioner.... already have two 12 VDC server power supplies.... Any comments here on the following new product..... RevoLectrix PowerLab 8 (v2) Charger 1344 watts

Here is a direct quote from EmpireRC in Arizona"... "We will be sending the replacement GPS units as soon as we receive them from DJI. Should be about 2-3 weeks. Sorry for any inconvenience." I've decided to take step back, canceled two orders for the WKM and switched to purchasing an in...

I'll be in Phoenix Arizona around Christmas time and have been considering buying a WooKong-M and related items while I am there. Any suggestions who to deal with in Phoenix area?

A quick look at the Multi Copter Forums world activity map shows the heaviest forum and multicopter user activity is focused on North America and Europe. http://www.multirotorforums.com/usermap.php With this in mind I was wondering, with respect to Asian produced Multicopter equipment, which...

Aaah yes indeed!!!!.... not obvious at first and 2nd glance but there are black strips @ 1 o'clock and 11 o'clock on the safer units.........and thanks for pointing out this important detail...........

The following notification from the manufacturer states a factory shipment cutoff date such that controllers shipped before that date are OK as is. But if after that date, it needs to be shipped back to the manufacturer. I wanted a long time for this item and do not want to personally get caught...

Excellent hardware and controller choices you have made. Where did you buy and how was delivery time and service?

DJI-Innovation products are an excellent choice.... Go with the NAZA controller for hobby level. It has good pricing, local availability and better service and delivery time than does the more costly commercial level WooKong M from the same manufacturer. I believe within the next six months...

GreenEggs, I am also from Calgary and migrated from the Blade MQX to the 6 prop FlameWheel F550 about six weeks ago..... but waiting more than 8 weeks for a special controller..... If you are into this primarily as a hobby then the NAZA controller will be a good starting point with much faster...

Please quantify "purchase after June 15 2012"! I ordered my WKM-GPS in late August or early September and it just arrived at my local Hobby store today! Local Hobby store ordered it from EmpireRC in Arizona. So the question is.... "Was this item purchased from the manufacturer's facility before...

I guess that is the nature of the high tech Hobby business especially with bleeding edge technology!!! Must have lots of patience and faith that they will achieve the required Quality Control levels to legitimately enter the Industrial and Commercial markets. Ordered by WKM-GPS in early...

Yes... that will work as long as both power supplies are on at the same time..... otherwise..... http://power-topics.blogspot.ca/2009/07/operating-power-supplies-in-series.html

Thanks for your concern.... This is not a task for just anyone hobbyist for sure!!! While it is a simple and straight forward task to connect two 12 VDC batteries together to achieve the desired 24 VDC ouput.... that is not the case when using two power supplies fed from separate 120 VAC...

Noisy is right... Took one of these apart and adjusted the voltage outputs to maximum, then searched around for the negative DC ground/earth lead hoping to be able to isolate one PS DC output as per the following link http://www.tjinguytech.com/my-projects/server-ps. But the link describes...

Thanks Kloner.... My two Dell-PowerEdge Server power supplied arrived yesterday and were only $33 each plus some shipping cost. Following http://www.tjinguytech.com/my-projects/diy-24v-47a for configuration. This forum works for me!!!

I just got the Fire Wheel F550 Hexacopter and need to pick out some APC or Graupner props for it. I am not familiar with props specs so what do I look for, i.e., slow fly/pitch or other? Which I could find Graupner or Xoar props locally. And should I choose 8 or 9 inch diameter or both? I live...

Which battery connector IMHO there are several reasons: 1) The primary reason for different connectors is that higher amp-hour batteries need heavier wire and connectors so that they do not get too hot. There is a lot of current moving through these connectors and battery wires during deep...

Yes Canada is 120 VAC 60 hertz including 240 VAC for heavy loads including electric range, electric clothes dryers, garage heaters and now for faster recharging of PHEV or Electric vehicles. Yes I can understand the temptation for individuals into electric RC to discover their 15 amp breaker...

To charge a battery you need a couple of additional volts to overcome the battery's internal resistance. For a 14.8 volt battery that can be charged to 16.8 peak volts you will need about 20 volts! Hence a robust 24 VDC power supply is required. Then there is the current requirement needed to...

Very useful information..... thanks. If I go with the Dell PE 2850.... do they put out 24 VDC or do I have to pair two to get that? It is hard to get all the specs on outputs for these from the internet.... In either case will I need to cut or install jumpers to the back or inside to get the...
