Best scratchbuilt foamie for 15 mph winds?

I have several parkflyers, mostly scratchbuilt foamies but also a Flylite, a balsa Tiny and a converted 100cm Fenix. My all time favorite is a home grown copy of the Lazer II. Our club electric-only flying field, though, is often pretty windy for those planes, so I'd like to find some foamie plans for something that would be more at home in the standard 15 mph winds at our field. RET is OK, but I'm very much into elevon planes and also want keep improving with 4 channel rigs. I've never flown wings and am pretty certain these old eyes would have orientation issues with them.

I've downloaded many dozens of plans from this forum and have spent untold hours poring over them and the threads they came from. I've toyed with the idea of scaling up some of the 36-40" w.s. plans to 55-50" and building them out of 1/2 foam to give them more mass for the wind. No doubt some of you have tried that - how did it work?

As designed, though, many of my favorites most likely wouldn't be appropriate for the wind at our field. I don't want to resort to some larger balsa ARF, so I thought I'd ask the experts here: if the wind is 15 mph and you just HAD to fly today, what (scratchbuilt foamie) plane would you grab?

Het Potshot,
I would suggest GPW's BluAlbacorde. I had mine built with 1700 BW and flew it on 3s with 7" props and it split the wind quite nicely. And thats a pretty small motor.

Real fun elevon screamer.

Dekans F22 and Simple Delta are both good elevon windy day planes too.
But the BA just looks so sweet screaming by at low alt.

Hope that helps bud.

Thanks, Jimmy. The BA is in the same general category as the Lazer, though with some noteworthy differences. And yeah, the Lazer looks cool down low and quick, so imaging the BA would look even better, streamlined as it is.

Thanks for jumping in, Wilfor. What's "MDC," by the way? I'd like to check it out.

A Boomer is easy to build and handles the wind its built for. A Boomer is a Flying Wing with a twin tail and small fuselage. The twin tail gives you more stability and the fuselage lets you mount the batt more forward.
All you do is pick the size Wing you want and add the parts.
Also my MiniMag does well in 15-20mph winds.
I scratch built a EPP Ultimate Bipe, 28" with symmeterical wings and at 6ozs flying with a 16g outrunner on a 3 cell, it does fine in 14-20mph winds.

Got any plans for this? Looks like a nice plane!

I wasn't personally successful with the BA (turned out it was because I had the pitch reversed but I had totalled the plane before i figured that out). I would still vote for it for this purpose wind. It's very stream lined and with not much side profile to get pushed around.

I would recommend a larger motor and battery pack for the wind as much as I love the Blue wonder. I think something along the lines of the BP-21 with a 7x5 prop on 3s would be great for a budget wind flier.

I totally agree. I only mentioned the BW as it was what mine flew with and wanted to express that even on a little BW, it went well. I still have #2 cut out and waiting to be built. (over a year waiting now...) It is getting the BP21 and 3s. Folks have taken it over 70 mph on that set up with speed props without much problem.

I've admired your boomers for some time. Do you have links for plans for either of those in the picture you attached?

I must say, on the F22 the 1700 BW on 3s & a 7x5 I think it was, it was a screamer. It was my fastest to date and the wind meant nothing to it. I couldn't even open it up at the soccer field as it wasn't enough room. And it is almost as simple a build as the BA. Then you can throw a 2s on it & an 8x4 and slow it down real nice too.

Mine is like a Potensky Uzi XL with a solid fuselage hollowed out and Ultimate wings. You'd need some tools to cut shape and hollow out EPP.

But there is a simular build, Potensky inspired that uses sheet for the fuselage. Using symmetrical wings really helps in the shifting winds.

Heres a link the the Boomer Thread;

You can build most any Wing into a Boomer.
Just figure out what size wingspan and buy or a make the Wing, then I can help you figure out the rest of the Boomer.
Also a Stryker airframe is only about $20.00 at the hobby shop, but expensive to ship. I've made Boomers and Stryker-Lites that will do 15mph winds easily.

Thanks, Butch. OK, I get it now. See, I was looking for plans for planes like the ones in the left hand picture on post #6. I'll see if I can scare up an airfoiled wing and take you up on that offer.

In the meantime I think I'll also look into cutting out a Dekan F22. I saw in another thread that a CF2805 is a popular motor for it, and I just happen to have one ready to go.
