i saw one of those BUGZ planes, they sure do look neat! i m not sure if they can be brought as a complete set, probaly can...
If you want something that can fly slow and turn tight, it depends on where you want to fly it, indoors? outside? in a small space? when you say landing gear, do you mean retracts with all servos and hardware? i have a few electric planes and gliders but they never came with a complete set of all gear and that, but i have seen a small selection of complete sets on the SMC site (www.sussex-model-centre.co.uk), i think most of them were fun electric gliders,last time i looked. price range seemed resonable. They also sell a few cheap parflyers, all ready complete with everything, in your price range..but they also sell the largest assortment of everything RC i have ever seen! There are many other sites as well, perhaps you would like to know them?
