Martin, I have 3 models from Richmodel (they are imported to Malta by a friend). They are an Ultimate 40S (41 inch span), a Long-Ez .46 (56 inch span), and a P-38 Lightning (51.5 inch span). The Ultimate is reasonably good, great every-day, chuck-in-the-boot flyer, needs a lot of right and down thrust - much more than built in to the firewall. Would help if you beefed up the undercarriage mounting before assembly. The Long-Ez is.... different. It's a canard, stall speed really slow. Undercarriage is a bit too far back from the CG which made landings interesting until I got the hang of it (basically come in a bit faster than you would with a conventional model and you can do greasers every time) Otherwise flies well enough, although mainly flat out with a .46. The P-38 is new and as yet has only flown twice. 2 x 350W motors in it with 3-blade counter-rotating props. Builds OK, slightly nose-heavy. Flies great, lands beatifully as long as you keep a bit of power on. Switching to 2-blade props for better efficiency. Can't comment on other Richmodel kits as I dont have any more. Except that my Dad has their new HondaJet. Flies great with 2 x 650W motors in it. As with most ARTF's though, the undercarriage ripped out on the first outing.
