ericrw Posted April 3, 2014 Author Share Posted April 3, 2014 Do I take it that power equals wattage ? Which would mean that it is 470 wattage. Thanks. Quote Link to comment Share on other sites More sharing options...
ericrw Posted April 3, 2014 Author Share Posted April 3, 2014 I was hoping to use this motor in my Dawn Flyer build but the recommended wattage for the model is only 300w. Or is it possible to use a 470w ? Quote Link to comment Share on other sites More sharing options...

Or is it possible to use a 470w ? The 'wattage' actually used will depend on what pack voltage, and what propeller you use. Watts = volts x amps. Amps, depends on the load on the motor, i.e. the prop size. One of the first 'tools' worth getting is a wattmeter. Quote Link to comment Share on other sites More sharing options...
ericrw Posted April 3, 2014 Author Share Posted April 3, 2014 I appreciate that the prop and esc would have to be acceptable to the 470w motor but would the increase from the recommended 300w to 470w, be acceptable to the Dawn Flyer. I`m afraid my understanding of electric is very basic and I appreciate the help I get from Forumites. Quote Link to comment Share on other sites More sharing options...
eflightray Posted April 3, 2014 Share Posted April 3, 2014 Assuming you're also an IC engine flier. It's no different really from sticking a 60 in a model meant for a 40, (and don't all IC fliers do that), it has the potential to go faster, but doesn't have to, depending on the throttle. The only other consideration is the same for the IC set-up, if it's heavier will it upset the CG. If it fits, go with it. Quote Link to comment Share on other sites More sharing options...

eflightray Posted April 3, 2014 Share Posted April 3, 2014 Just looked up the Dawn Flyer, a 48" span early monoplane, open rear frame. The Turnigy is a bit of an over-kill, but then she should cruise round nicely on low throttle. Maybe something like a 12 x 6 on 3s Lipo.

Toni Reynaud Posted April 3, 2014 Share Posted April 3, 2014 Put the big motor in. The 470 watt statement means only that it is capable of handling 470 watts. If you put a smaller prop onto it, you will find it pulls less power. This means that you can choose a prop so that the motor will only pull 300 watts. However, if you put a bigger prop on and static tests with the aforementioned wattmeter shows that it pulls 470 (or 450 or even 500) watts, just fly at less power (part throttle). This is what is meant by choosing a prop to suit the plane/motor/esc combination. Another vote for getting a wattmeter - leccy fliers can't really do without unless building strictly in all respects to a proven design specification which includes motor, propellor, ESC and battery specification. Vary any one of these and the wattmeter becomes your very useful friend. Edited By Toni Reynaud on 03/04/2014 14:45:04 Quote Link to comment Share on other sites More sharing options...
