Hi, All, I am what most of you people Call NEWBIE LOL, So please bear with me. for I will be posting, and asking a lot of Q? Iam Really inpressed with the very helpful Articles I HAVE ALREADY found, and read, My 1st question is can some body point me in the right direction of a realiable and easy to use Watt meter, my flying experience, is limited to GWS Park flyers , for the moment, Thanks in advance for info............kid
The inline wattmeters will give you more information.
My flying friend has one that will record and hold the peak value, so you can pay attention to the plane. That is very nice with larger planes. I wish I knew the brand.
Hey, road king 97, something tells me you ride a 97 Harley Davidson, Road King, nice bike. I ride an 85 Honda Goldwing Limited Edition, any chance I get.
Back to the subject, that wattmeter at Value Hobby looks like a good deal. I spent over twice that on mine but I don't regret it at all.
Keeps you from burning out a motor.
Will tell you the power consumption of your plane, so you can figure out flight time.
I run the plane for 1 minute at about 75% throttle or what ever amount flys your plane nicely, then look at total mah used. It is simple to compute how long you can fly, before your battery is at a critical level. That keeps you from toasting them.
If you see input voltage drop too much with load, that is a sign of a battery with a high internal impedance, either too low a C rating or it maybe getting old.
I have tested props of the same size & pitch, but different brands, and found huge differences in power out.
I think a wattmeter is absolutely necessary for electric modelers.

I had a 85 goldwing back then and now i ride my 97 road king . I call it my Barny bike because of the purple color. lol Iam pretty sure you use the same plugs on your watt meter inbetween the esc and motor to see how many watts its using . I need to buy one soon myself and read the directions.lol Wildfire how do wire yours to test the draw ? joe
Thanks ,Joe Aguy at a flying feild mentioned to me that I buy one, I don,t know how they work yet, but when I do I will be able to run my esc , motors, & batt, with out over heating............I think
Hey Bill so you finally joined good to have you here. That watt meter will save you a lot of guess work and possible damaged electronics. This should be one item every new guy buys when they get into electrics.
It is real nice to know what your system is doing for watts and amps instead of guessing like I did in the beginning.
By the way did you get a chance to take a look at that TX problem with the throttle?
Hey Gramps! iam going to buy one too,i ripped the brushed motors and gear boxes out of my short solent and bought new brushless motors for it. I will be trying new 3 bladed props and new hubs too so using the watt meter will come in handy. The only bad part is the slot i had to cut under my wing to rewire it all ,knda made me sick when i had to cut her open.
Joe shame on you! Building them big beautiful planes and not checking the power system out.
I think I waited at least a year and half before I got one now I couldn't imaginee being with out one. Nice to know what the watt's is going on.
Hey, John I took TX apart found nothing, put it back together. and every seams ok Ithink I will let Rene look at it ???, Iflew on Veterans day with my Grand daughter and all went well, Hey bye the way thanks for all the help at feild last week.............BILL
I know Gramps i should have bought one by now but with all the balsa i buy and foam latley my extra airplane fund has been low. lol Happy to see your doing well Gramps !.I just bought 3 motors ,8 servos and 3 esc's from value hobby and all my stuff arrived fast and not broken ,they are pretty good . joe
A wattmeter is basically inserted between the battery and the airplane.
The battery plugs into the source side of the meter, and the plane plugs into the load side.
The meter reads both the voltage being fed into the circuit and the current flowing through it.
Then since watts equals volts multiplied by amps, the IC in the meter is programmed to display the answer as watts.
The meters also count time, and use that to display mah (milli, amp, hours) used as time goes on.
Kidhicky you have a granddaughter so you fit right in with us old farts going through our second childhood. Motorcycles /toys /street rods ,life is good. Iam mean as ever Gramps and still riding my harley even tho the grandkids want to get their grubby little mitts on it. Good luck with flying rc Kid . joe
