32" EPP Flat/Profile 3D Foamy

Here's my impressions of my new 32" EPP Yak from WM Parkflyers. Comments welcome.

My Background:
Coming from electric helicopters, my first two 3D flat/profile foamies were 38" then 48" Depron from DW Foamies. Those planes fly very nicely, but I wanted something smaller for more confined spaces like a large back yard or small ball field.

The build was very easy and straightforward. I love the fact that EPP can use Welder's glue (Depron can not). I think the flexibility of the EPP would not do well on larger sizes like my 48" and maybe even my 38", but this 32" wingspan is great. The weight (8.5 oz with 460 mAH 3S) is light enough as not to cause the airframe to flex too much during flight. And generally 3D type flying is usually slow. I used Krylon Fusion spray paint with no problems.

One surprise is this 32" Yak does not have any more trouble when the wind picks up than my 38" does (even though the 38 weighs twice as much). I expected it would really get tossed around, but not so. Using the "blue wonder" motor and 8x4E prop, it has plenty of power to fly straight up or against a good wind. Hovers nicely, although I'm not very good. And not too much prop torque wanting to rotate the plane. Hand launches easily, flies right out of my hand. Since no wheels, I try to land in tall grass.

All in all, my first EPP plane is a success, and I'd recommend it to anyone wanting a fun 3D foamy, for outdoor areas of limited size.

BTW, you don't have to fly 3D to enjoy a foamy like this. You can dial down the control throws (dual rates, etc), and fly this thing like a normal sport plane all day long. Makes it an easy beginner plane because it flies so slowly when you want it to. For you newbies, the reason it flies slow is the very light weight relative to wing area. I'm not associated with the maker, just a happy flyer wanting to share.

Also, I can't claim the paint scheme is original. I copied it from a picture in a forum awhile back. Hope it wasn't copyrighted.

Take a look at Techone. They have a good selection of foamys in the 30in wingspan sizes that fly superbly,look good,and are inexpensive to buy.

Thanks for the review! That looks like a kit version of Leadfeathers Yak55 from the scratch-building forum... I am tempted to build one for my first scratch-build, glad to hear it can handle some wind!
