Man that was a beautiful video. It should be the sales video for this bird. I like the way the birds in the video seemed to be playing with you, gives new meaning to flying buddies. Thanks for sharing.

Hi Guys

I’m new here……..This is my first post on RC groups……..

The E-UHU is in my opinion a beautiful plane so I’m following this tread with a lot of interest
I’m a starter with heli flying a I want to follow up with airplanes ( I can do nose and tail in )

I was wondering if it is possible to learn the basics of flying with the new UHU ?

Please is there someone who can give me any advise regarding the UHU as a basic starter…???

Thanks
Ferdy

1. switch on TX, put throttle stick to neutral position (engine off)
2. connect to the battery, switch on ESC
3. ESC beeps 2 times
4. press "set" button
5. ESC beeps 1 time
6. keep throttle stick at neutral position until (after 2 seconds) ESC beeps 2 times
7. a) If you don't want to use the engine brake, put the throttle stick to full power within the next 3 seconds.
Keep it there until the ESC beeps 3 times.
7. b) If you want to use the engine brake, put the throttle stick to full power within the next 3 seconds
and after that immediately put it to the braking position. Keep it there until the ESC beeps 3 times.
8. The ESC will be activated as soon as you put the stick to neutral (or brake) position.
It will confirm that by beeping 3 times.

Note: The soft start-up will be slower if you program you TX to use large/long stick travels (100%).
It will be faster if you do not programm small/short stick travels (50%).
I.e. choose the stick travels to suit your own comfort needs (regarding soft start-up and brake).
Hope this helps.

Hi Ferdy, and welcome to rcgroups

The UHU will make a good beginner's choice.

Its just as easy to fly and setup as the Easystar, but it won't hold up as well if ever you do crash. The recommended brushed 400 motor and ESC is also a good bet. Its only slightly smaller than the Easystar, but is much lighter, so it fly's with very little power or speed. The Easystar has been out for a long time, and its quite nice to have something a little different, so I would recommend the UHU.

Hi Mark

Thnx for the welcome
I was, ( and i am) really impressed by your site.

You gave me the answer I was hoping of…
I was switching between the EZ* and the E-UHU …I know the EZ* is very well and strong designed. But I really do not like the looks …
So the only thing I’m worried about is the crash resistance of the UHU……. Hopefully they sale spare parts.

Do you know any methods of reinforcement????

I already told that I’m relative new on the forum…..so I also need a little bit advice regarding a brushless setup…I do like to fly my heli brushless and I also want fly the UHU also brushless..
Of course it must be good for me as a beginner… ( ea not to much power) …but I’m a little bit confused ( as we say in Holland … I can’t see the tree’s trough the forest anymore )
I also downloaded the program propselectror but that one doesn’t work for me

Please can you advise me

Thnx
Ferdy

Hi Ferdy,

If your thinking of a brushless motor, then now is the time. Because you glue the motor down on the UHU, I think it maybe a little hard to remove afterwards, so it's probably best to put a motor in now which your going to stick with. There's plenty of choice regarding brushless motors. I would look for something with a KV rating of about 2000. I could name a few, but it all depends on whether you can get them in Holland. Its an idea to have a look around, then if you see one but your not sure, let us know. What battery will you be using ?
As far as reinforcement, there isn't anything you really need to do. I never bothered with the two wing wheels that come in the kit. Unless you take of from a silky smooth runway they'll be no use. Just run a little tape on the underside to protect it on landing.

Hope it helps,

Mark

HI,

I had in mind this one

Typhoon 6-15 motor specifications.:

Voltage: 7,2 - 14,4V
KV: 2150
Max. Power: 125Watt
Max efficiency: 80%
Amps with max efficiency: 6-12 Amp
Axel diameter: 3,2mm
size: 25x29,2mm (excl. as)
weight: 43gram

Advised models of 350 to 600gram:
6x6 prop >> Lipo 2s
5x5 prop >> Lipo 3s

http://www.rctechnics.nl/images/aand...n/typhoon6.jpg

or this one

http://www.towerpro.cn/english/motor/2415.html

I think the first one is to be preferred… the second one is maybe a bit to much

Thnx
Ferdy

Ferdy,

The Typhoon 6/15 is an outrunner, ( the outside can of the motor spins). You will need an in-runner. You would have to build a proper mount, which is a lot of work to use this motor.

You'll need something like this http://www.e-flight.co.uk/shopexd.asp?id=88

This motor would be ok using a 5.5x4.3 prop. The 5.5 is the diameter, which is about the maximum you can put on a UHU. You could use a 2s or 3s on this motor.

Any fixed prop will significantly reduce the gliding performance of the E-UHU when compared to the special folder.

With the fixed prop, the UHU glides forever as it is Jurgen ( see vids ). You will not notice any difference

Hi Guys,

Yesterday i ordered the UHU at the local hobby shop.
I was planning to use the engine from the store Mark recommended to me

http://www.e-flight.co.uk/shopexd.asp?id=88
(THNX Mark fore the site link )

Of course with my FUTABA FX18 and a 40A Advanced Brushless Balancing ESC form HiModel.
The receiver will be the ACT pico4 and the servo’s the Micro Servo 5 gram from Tower Pro.
For the batteries I was planning a 2s 2200mah LiPo witch is already in the house.

BTW I’m not completely shore what kind of prop I will be using ….

Again…thanks fore the advise and I let you know when everything is ready

Believe it or not, but the extra drag of a non folding prop on a model like the Tipsy or the E-UHU is really noticeable.

Hi Ferdy,

Somehow, your drive system and the size of the model seem to conflict with your servos.

Indeed it looks a little bit to weak …….
Thnx for noticing!
Those are the servo’s I had on the shelf…..

BTW A also have a lot of the FUTABA S3102 that I use with my ECO8.
Last year I bought 10 of them for a "very special Price"
They are much stronger and a lot heavier.

To me they seems a little bit to big or am I mistaking ???

Otherwise …I always can order the HS81.
