World Models Groovy 50 is relatively new entrant. It was announced about 12 months ago, more or less a more contemporary good looking cosmetic update replacing the Zen 50, but to date it hasn't achieved significant inroads in terms of market penetration in what is an hotly contested segment.

As good as most and better than many, price vs quality and performance wise it's very competitive. I suspect the reason you're not seeing many on flying fields is that athough against strengthening quality competition WM have dropped their prices significantly over the past twelve months from the premiums they used to charge, at that pricepoint it is still dearer than many of its class competitors which observably affect sales in that class.....at least in this country.

I can earnestly say that I have never flown a WM design that doesn't fly well. At the size and weight of the Groovy 50, your .46AX WILL have gobs of power to drive it around the sky. On 10% nitro, the combination will perform all the Sportsman pattern maneuvers (full schedule) with ease on a standard supplied muffler. A solid combo for entry pattern. In four words, buy it!...start practising!

Nothing much to say about assembly. It's a World Models ARF says about all. They do a great job OOTB. Just follow the instructions and use their hardware. At entry level, putting your time, money and enthusiasm into practice will effect a superior pattern result. Buy it and get on with it. Keep it simple by using your reliable, inexpensive and sufficiently powerful AX spending the saving on burning fuel instead of unnecessarily lashing out an expensive vogue four stroke status engine. (YS or Ultimate). If you decide you like pattern with promotion points coming rapidly and easily to you, that'll be the time to reconsider which combo for the next step and time to trade-up with much to outlay then if you want to remain competitive in Advanced and Expert. For now, your choice of the Groovy F3A and .46AX combo is solid enough for task.
