Venus is great. I also have a Groovy from World model. My Venus did fly better than Groovy 50 3A, even if the deferens is small. Groovy is more easy to transport because of two-piece wing.
If I shall rate Venus and Groovy 1 to 5:
Pattern flying: Venus 5 / Groovy 4,5
Quality: Venus 4 / Groovy 4
Easy to build: Venus 4 / Groovy 4
Easy to repair: Venus 4 / Groovy 3 (Groovy is covered with World Models film. Venus has Monokote ho is more easy and faster to buy in case of reparation.)
Easy to transport: Venus 4 / Groovy 5
I can recommend both, but if I shall choose one it will be Venus.
