Buttercup 50" foamie

I saw a beautiful little plane on the Parkflyers thread several months ago called the Buttercup. http://www.rcgroups.com/forums/showthread.php?t=561552

I thought it looked so cool that I ordered the plan from RCM Mag. I've been fooling around with it off and on for a couple of weeks and finally finished it tonight.

50" ws
10.5 oz without battery
Custom CDR double stator motor
1060 prop

The fuse is EPP reinforced with a couple of fiberglass rods running nose to tail. Wing is FFF. I was surprised at how light it came out, esp since I painted it. (A Buttercup just has to be yellow.)

Looking forward to maidening it tomorrow, weather permitting.

Pat - I saw the Buttercup thread too and really liked the lines of this plane. Yours is beautiful and should be a nice slow flyer at <11oz with a 50" span.

Hope that you can fly it tomorrow!

Nice job,
Gary D.

Looks like an exceptional floater. NIce build. What braces the wings?

Nice job. There's just something about that design. It just sits there dripping appeal all over the place.

Tony, amazingly, I don't think the wing needs any bracing. The wing is long, but has a narrow cord. I did apply heat to the wing as I formed it. I know that adds a little stiffness. I also ran some light packaging tape along the leading edge and on the top and bottom of the wing (similar to Waterdog's STC). Seems pretty sturdy as is.

Gary, Kim, Bullseye, thanks for the kind remarks. Yeh, there's something about the beauty and simplicity of this design. The balsa builds on this are really neat, but it also seemed like a natural for foam.

Far too windy today, but I did put it in the air for a couple of minutes. I gave it just a little throttle and it soared. Other than that, I don't really know much about the flight characteristics. Looking forward to a calmer day to put it through it's paces.

Paul, yep, FFF for the wing. The EPP fuse and FFF wing is probably a good combination since it's usually the fuse that take the heavy hits in a crash. At least that's been my experience--and I have a lot of experience!

Very cool... Looks like something that would be fun/able to fly around over the house... Enough wing and power to lift off quickly, and then enough wing/low weight to float around...

Figured you'd have some plans like this stashed away... Can't wait to try that Wedgie in foam too.

Worked great for the legendary Leon Schulman...So many Old Timers can be made into Foamies... I'd love a Comet interceptor.. and a Strato Streak , and a Brooklyn Dodger, and a ...................so many really great planes from the past to be made into foamies...

Freds Simple Duster, peeled sturdyboard and undercamber wing. The guy knew the meaning of simple and how to make them fly great. IPS powered GWS electronics. Coat hanger landing gear and dollar store toy wheels. I think he would have gotten a chuckle out of it!!!!!!!!!!!

Maiden flight...finally!

I finally had a chance to do a real maiden flight on the Buttercup. Take this with a grain of salt, because the last plane I build is usually my "favorite," but I can't say enough about how wonderful this plane is.

Weather has been rough here, until recently. Friday morning was perfect for a maiden flight. Almost no wind to begin with, then it picked up just a little during the hour or so I was out.

No surprise to anyone, but this is definitely a slowflyer. It might pass for a powered glider. The thing that amazed me was how slowly it could fly w/o stalling. I could take off at around half throttle, fly to a reasonable altitude, and cut back to a quarter to a third of throttle.

I tried a few fancy maneuvers, but the real joy of flying this plane for me was just cruizing around...low and slow or very high (it's easy to see a 50" wing!).

At one point, while at a fairly high altitude, I pointed it into a gentle wind, brought the nose up and cut the power as low as possible without losing altitude. This may have been unusual wind conditions, but I watched the Buttercup "fly backwards" for a good minute or more. It was so cool.

When landing, it seemed like I had to fly the plane down, letting the prop turn about as slowly as the clicks on my throttle would allow (1-3 clicks up from power off) in order to land.

This isn't a good windy day flyer, and not one for those who want to go fast, but for lawn chair potatoes like me, it may be the perfect plane! I'm not an AP guy, but I imagine this would also make a wonderful AP platform. Try one. It's well worth the price of the plan!
