EPP F3P Practice Plane?

[3d_Crazy]

I wanted to see if it was possible to make an EPP "shock-flyer" for F3A/F3P. The majority of this plane is EPP. It also has 3mm Depron in certain places to stiffen it up where needed.

I need a forgiving plane to start practicing F3P. I flew it this weekend indoors and it did great. I'll post a video if I get time. :)

Whatcha think?

Seeing it fly was very impressive.

Tim, Very unique way of bracing the EPP! Lets see some vid! Looks fun.

[pkruse]

Cool! Im looking for an EPP practice plane but there seem to be few options. Any more details on the build would be appreciated 3d.

The build consists of 6mm EPP and 3mm Depron. Also used was 6mm flat carbon fiber as well as .040" flat carbon fiber.

I'm now looking at ways to possible make it even lighter and keep it stiff. Once we get it all worked out, we will probably kit it.

Whats it weigh?

[Zimbo]

Looks great can't wait for you to kit it!

AUW = 7.2oz

AXI 2204/54
TP 480 3S1P
GW 9x5 HD

It flys nice at 7oz, but I'm still going to see if I can get it lighter. :)

[Devin McGRath]

wow looks neat ight be good for practicveing low pattern stuff.

Thanks. The hardest part was trying to keep it light while keeping everything stiff. Twisting fuse and mushy control surfaces don't work well for precision F3P. I'm happy to say it is very precise (and durable). Now I just need to learn to fly it :D

I'll edit up some video tonight if I can find some time.

Yes we see the port side aileron tip ;) :D I say not bad. Mine would have been in peices :rolleyes: :D

[ChrisBowker]

are the ailerons made from depron?

Chris

[3d_Crazy]

Yep, the ailerons on this version were made from 3mm depron. And as you can see, the EPP handles the boo-boo's better than the depron :)

The next version might not have depron control surfaces...

[ChrisBowker]

folow up question, im wondering how well the model snaps? thanks.

Chris

[3d_Crazy]

very good.

[Pjotrrr]

Interesting design! Wingspan?

[3d_Crazy]

Wing Span = 33"
Length = 34"

[Team3D]

WOW, I have to have one of these :D
How would you think an axi 2208/34 work on this??
Also, Need an Beta tester :cool:

Awsome,

BTW- How awsome is it to have an indoor f3a/pattern thread

OK here is a small video. http://www.e-foamies.com/videos/EPP/F3P_EPP/F3P_EPP_01_edited.wmv

I'll see if I can edit up the 2nd one with more 3D flying that shows some snaps and torque rolling :)

Tim, that looks really nice and gentle!! I'm going to have to try one!!! Keep up the good work!! later Chris

[Jeff Pfeifer]

Looking good. Need to be alot slower though.

[BillyM]

Very clever design. I've built many EPP foamies and have always struggled with "wing warp" doing tight loops etc. The eliptical wing shape, reinforced with flat CF along the leading edge will go a long way to stop the warping. Thanks for sharing this one.

By the way, nice rolling circle in the video. Is rudder the main input used?

Bill

[3d_Crazy]

I used elevator and ailerons to do the rolling circle in the video, no rudder.

Jeff, I agree. The only way to get it slower would be to get it lighter, that is why I'm going to make a similar design from 3mm depron. Durability has its cost in weight, but it is great for training the fingers. Once you get the inputs down moving to a slower plane should only make it easier!

Jeff, what prop do you use on your AXI 2204/54? I was just thinking if I switched to a lower pitch prop, it might help it fly slower....

[Jeff Pfeifer]

My motor Set-up is as follows for F3P:

AXI 2204/54
Castle Creations PHX 10 Esc or Jeti 4+ (I have used the Jeti-4+ with good success and is a couple of grams lighter than the cc)
Kokam 2s 340
GWS 9x5 DD prop

Also as a tip! Set your motor up to have a very slow Idle at low stick, and then you can use your trim to cut the motor off once you land. The large, slow turning prop will help slow down lines alot!

Looks like it may be a little heavy for comps, but maybe as a practice plane?

Looks kind of Knüffel-ish, only heavier.
