also someone mentioned how these planes aren't supposed to be flown like a sport plane? Very very wrong. These designs are supposed to be able to perform pattern schedules and should easily be able to travel at same speeds as advanced trainers etc without any problem.
No, no, no, no
NO!. The Funtana 40 could probably get away with a little more speed but the Funtana 90 is DEFINITELY a 3D thoroughbred. That's it. If you fly it at pattern plane or advanced trainer speeds, plan on taking a couple trash bags to the field with you. This isn't a 'second' plane...maybe not even a third. Depends totally on the pilot and whether he possesses the discipline that it takes to fly the plane in it's intended flight envelope. The Funtana 90 is built very lightly to excel in 3D, which it does.
From what I've seen so far most of the problems that people have had can all be attributed to improper props, servos, linkage setup. Granted, I'm sure that there are a handful that ARE defective or suffered shipping damage (not always immediately visible), but the vast majority are fine...including mine. It is a light and fragile airframe...treat it like a Stik and you'll suffer the consequences.
If you hammer the aileron servos in, you're going to crack ribs. If you use an 8-pitch prop, you're going to have flutter. If you use cheap servos because you already have them, they are going to fail. If you don't understand what 'mechanical advantage' means, find out. If you insist on using an engine larger than a Saito 100 or YS 110 and don't always apply proper throttle management, plan on landing with no wings.
Yes, a tiny bit of extra work needs to be done. Pinning the firewall, different tail bracing setup (in my opinion), better tailwheel. Just because the servo holes in the tail exist doesn't mean that you have to USE them...install EVERYTHING before installing the radio gear then check the CG...you can relocate servos, but the engine usually needs to remain in the front.
For $209 just think of the work that you DON'T have to do! This plane is a tremendous value, excellent design, and 3Ds as good as any ARF out there that I've seen in this size...though I have not flown the Extreme Flight 68" Yak.
Build it right, build it light, and wind it tight. Slow and low is the tempo.
