I think it's the first time in one year and a half of RCU that I will have to disagree with minnflyer's opinion




I have several wonder in .15 and .25 size, modified with rudders and also build with stock fins. I also made a twin wonder.
All of them are great flyer, but fly diferently. The .25 is of course heavier, so the aproach and landing speed are a bit faster and it fly only a bit more faster than a .15 one fitted with a good .15 LA
In my opinion, the wonder is the most funy when it's build how it has been designed by bruce tharpe. LIGHT with a .15. it will have unlimited verticals and a top speed around 70-80 MPH

the price to pay in wingload in order to accelerate this thick profile around 100 is in my opinion to heavy !
there are more judicious choice of plane to fly fast with a.25, but a 15' nimble flight with a 4oz tank and a gentle approach with your.15 powered wonder landing at your knees is something unique !
