Question
What edf plane for 10 or 11 cells?

Hi All,

I am in the market for a edf jet on 10 or 11 cells.

The reason for the cell count is the fact that i own 5s 5000 hyperion packs.
I use these packs as 5s or as 10s packs in my f3a plane.
So 10s would be the most economical (i already have 4 5s 5000 packs)
And with some investment i could buy 2 6s packs to make 2 11s packs.

And now for the plane part ;-)

I started the search initially for a turbine trainer.
Came up with a boomerang and a jetcat p80se.
But the turbine operation, maintenance and the limited flying fields where turbines are allowed kept me back from buying.
As i am a electric fly er for the rest of my planes it makes sense to look at the EDF market.

I want a jet that can take off from grass and on 100 meter fields just like a boomerang trainer could.
Is this feasible with today's edf technology?

Would an airframe like the boomerang (ducted for edf off course) work or can I go to a more sport scale plane?

For flying style a boomerang (turbine trainer) would be enough for me, for the looks i would like a f-86 or F-16.

Can you guys give me some help on today`s edf planes.

My edf knowledge is limited to a kyosho f-16 and f-86 (converted to edf).
I do have a lot of experience with larger planes and also with faster planes (funjet on 5s..)


Best regards,

Edwin

You will be wanting a Tazor then

http://www.rl-comp.com/#/tazor/4539520346

Welcome to RC Groups, how about providing some more info on your profile?

Some advice may be continent or area specific.

Hmm could it be that simple?
haha

I thought it would become a big search....

The tazor looks really great and should fit my needs.
Seems this jet is designed for the smaller fields in europe.

I will start searching for more info on this plane.

Regards,

Edwin

Do a search for a thread in this forum called 'Tazor takes a bow' I think you will discover more to your liking, even to the point that my original design team were Austrian and German. See how well the prototype flew on 10s in Salzburg flown by the late great RD, link on the RL composites site.

The Tazor was designed for all the reasons you describe.

I read the thread about the tazor.
This plane is defenitely on my wishlist now
Send an enail to chris for a price info in euro's.

On the site i see the tazor is ready for some fans.
What fan is recommended and what cell count?

1st prio is slow speed handling (short takeoff, slow landings)
2nd prio is speed (as much speed as possible without affecting prio 1)

So a light setup using 10s with the best fan combination or should i go for more cells?

Regards,

Edwin

The Tazor is optimised for 110mm fans 10 to 12s I particularly like the Stumax SM110-52 on 11-12s 35-45c 5000 mAh cells as it gives good flight times and speeds around the 145-153 mph (240 kph) mark at around 3,800 - 4200 watts.

Good throttle and speed management will give you 4.5 min flight times with a useful turn of speed for some head turning fly by's, just what you need for a well balance club field friendly sport jet.

Also very good (as seen in the prototype) but very noisy is the DS75 on 10s with the Neu 1521 - 1.5y (as seen in the prototype in Salzberg) or 1527 2.5D on 11 to 12s. On 12s with this setup you will be pulling 5,000 watts with speeds in the 160 mph (250 kph) range.

Also good for higher speed on 11s 35c but a bit quieter so nicer for the neighbours is the SM110-45 on a Neu 1527/2.5D. That will be around 4,800 watts.

Aeronaut also have a 110mm derivitive of the famous TF4000, but I have not seen one and have no performance info.

I will be flying the Tazor at Arizona Jets in a few weeks, rather looking forward to that The models current owner does not mind overseas 'Friends' flying his models fortunatly hopefully we will get some more video.

The Tazor is also blessed with the heavy duty undercarriage option, on a grass site dont be tempted by anything less.
