Keith did great job on the Riser, We've flown our Riser 100'son all of his visitsto Mobile, we built them at about the same 04 I think. They are great fliers ballasted properly you can fly in any wind conditions. andby all means incorporate the spoilers, hooked up properly with a couple of micro servos you won't regret having them whether for landing or getting out of killer thermals. by the way I let him launch forme with theRiser and a 2M spirit with out a problem. He's a great flier and friend, just don't bring up the 4th. The kit is a excellant build and a lot of fun to fly Joe
