Electric helicopter MR rpm droop test.

- Doing a 180 turn in a quick stop and then pulling into forward flight allows very high MR power to be pulled at hover height and virtually zero speed, easy to recover if something was to go wrong.
Finishing off with a pirouette around the nose.
Excellent…👍
Lots of power! Can you make a video showing us the motor and talking about its power? Also what batteries are you using?
EMRAX LIPO
The power is limited at 30kW, the motor can do much more than that but I don't want to push the batteries harder at this stage.
Trou is onto it, it's an EMRAX 228 motor and LiPo batteries that are managed with exteme care.
I just stumbled onto your channel while doing a little daydreaming of a electric mosquito lol. I live in rural NV and have been thinking of tinkering with a mosquito next.
What is your impression of the electric vs a traditional internal combustion. Any obvious benefits? What is your range/flight time versus a traditional setup?
This is a great advancement for ultralight helicopters. What is your intention? Is this a one-off design or do you plan to market and sell this? I know the Mosquito Air is no longer in production but that could change. I owned a Mosquito XEL (the "Mad Mosquito") with my father. I am a professional commercial helicopter pilot but prefer to fly the Mosquito as an ultralight (Part 103 legal) to avoid all the hassle and I would love to have a simple electric machine. Your electric Mosquito Air is the coolest thing I've seen since the Mosquitos first hit the market!
Your dad was really passionate about his Mosquito, great to see!
I've sent an email to Dwight about my plans for the next version based on an XE, haven't heard back from him yet. It's very unlikely that it will be possible to get under 254lbs including battery though. In New Zealand all helicopters have to be registered so that's not an issue.
@@OskarRDA Does the battery system count against the weight of the helicopter for qualification of legal (part 103) weight? Fuel doesn't so why should the battery? I have seen this subject discussed in regards to electric ultralight planes and the general consensus is that if the battery size doesn't exceed the dimensions of a five gallon tank the FAA won't even bat an eye. Part 103 was written long before the possibility of today's light weight battery technology. More batteries doesn't equal more flight time as I'm sure you've long since figured out. Most people don't realize that there is a point where the extra weight eats up more capacity than it brings. I think the power system you have would result in a lighter XEL which is already Part 103 legal when flown with floats installed. I would still prefer the Mosquito Air just because weight counts soo much when doing anything electric plus I am tall and have to hunch forward to fly an XE/XEL. I also like the simplicity of the Mosquito Air and the unobstructed view is really great. I've only flown 4 different Mosquito Airs and I loved it every time. How much does the power system weigh with and without the batteries? Feel free to email me if you don't want to discuss anything in the open. I am still very good friends with Dwight and have been meaning to talk to him about your machine. kmthompsonpilot@yahoo.com
In Germany batteries are not counted as weight in their >120KG aircraft class. The US part 103 was crafted without vision of electric aircraft. But my understanding of the regulations allows for 5 gallons of batteries and the weight is not included in the "254 lbs empty weight". Also the FAA has clarified before that you're allowed to carry more than 5 gallons of fuel, but it must not be usable, i.e you would need to land and then refuel the aircraft. 254 lbs is the maximum weight of the empty aircraft, it does not include pilot weight + fuel + baggage ect.
@@funkysaxmankt Now that would change everything! Even an electric XE would be under 254lbs if the batteries were not included.
@@OskarRDA What is the weight of your electrified Mosquito with and without the batteries? If you think an XE would come in under 254lbs then your Air Must be super light!
what current is the motor drawing in these 180 MR power turns?
I limit the motor power to 29kW. Don't know what the motor current is, but with a battery voltage of around 360V the maximum battery current is thus roughly 29000/360 = 80A. The controller is rated at 300A continuous.
Any thought of enclosing the props for the tail rotor to make a verticle fin to aid trimming in forward flight and reduce the workload of the motors?
That's been on the list for a long time, just haven't got to it yet. The tail flies nicely just the way it is so no real pressure on that one.
Did you go direct through emrax for the motor? And what sort of controller mate?
Yep, EMRAX is easy to deal with. Controller is a PM100 from Cascadia Motion.
Have you read the Kiwiflyer article? You can download it at www.hfpower.co.nz
@@OskarRDA did Emrax recommend the Cascadia Motion controller for their motor?
@@bradsamers3014 Yes. It's a very good controller.
Is motor directly connect to the main rotor without any gear system? And how did you accelerate the motor from the start until it fly? Is there any mechanism ?
Have a look at the other videos in this channel, and at www.hfpower.co.nz/Oskacopter.pdf
need a licence?
What is the maximum residence time in the air?
I regularly fly for 15 minutes.
