Does any one know of a good multimeter (available in the UK) that would be suitable for the electronics, batteries etc in the Cub? I've done a search but nothing of note came up.  |

Probably any brand will do. I have a Fluke model 75 at home and at work. Love 'em. Modern equivalent could be Fluke model 114.

Is that not what you use to test the condition of batteries?

yes thats right diamonddog.
I only ask as i think its an unnesasery cost if your a beginner, or just if you have a cub.
batteries dont cost much and as long as you make sure there disscharged and then charged long enough for a good flight then whats the point. i have about 5 batteries. 3x 8cell and 2x 9cell.
i take out two at a time and just rotate them when they run out so next time i come round to charge i know there pretty much drained.
i would spend the money on a good charger.
thats my opinion.
but the fluke brand that spar uses are popular.

I have the MAS830L in the link you provided and it is a good meter. It never hurts to have a meter around. I use mine all the time. BTW a good fluke meter is gonna run you at least 100 bucks. I think I paid 225.00 for mine but it does way more than anything you'd need for this hobby.

P.S. A good charger will have a voltmeter built right in. SOme chargers have a place for you to plug in your meter...and the price usually reflects that.

A possibly more useful tool if you intend to stay in the hobby is a wattmeter: www.rcgroups.com/forums/printthread.php?t=311574There are several versions of the device, this is the one I got and am familiar with. It will measure battery voltage, but even more important you can put it in line and check voltage (drop) while running, amp usage, watt output and several other parameters. If you hook it up right it can sit between your charger and battery and measure the volts, watts, and amp-hours put back in. When you move away from RTF planes where someone else has figured out the motor/battery/ESC/prop combinations for you it becomes indispensable. When you read in other forums about fliers throwing around that data about amps/watts/etc. they get it from something like the wattmeter. There are a couple of threads in here where someone revamps a Cub with a brushless motor and everything that comes with it and promptly burns up the motor with too much prop. With a wattmeter and knowing how to use it that should not happen. fly |
