Duck,
The best I have information (real radar gun data) for the Patriot .40 with a SJ-50 (ss muffler) engine, retracts, extreamly cleaned up, topped level flight speed just at 150 mph (two way average)
Tbe best PatXL so far has come in around 150 mph average too with a SJ-90XL
The DC-20 checked in around 140 mph tops.
Magnum with a Jett 50, (ss muffler) - I received a report of 185, but Im not entirely sure on that - but its realistic I guess.
A competitive AMA 428 class Q-500 aircraft typically flys 160mph or or better on course, and can top 175 in level flight after a dive entry.
My suggestion if you are on a budget..... really want to go fast .... and do not mind building a bit...
www.matneymodels.com try a Mad Dog Q-500. Not a 2005 all composite Q-500, more of 1996 vintage, but it is pleanty fast, not expensive, and will give you a final product that is a step above one of the ARF's available at this time. Easy to build, has an epoxy-glass fuselage. Comes as a basic kit with wing cores, a fuselage, and a set of plans/instructions. If you can sheet a foam wing, you can build this plane. For power, drop Jett an email
[email protected] and request the Hangar Sale list - include in the email a request for information on some of Dub's "Used" Q-500 engines.
DaveN on here use to have wood Seeker 500 kits (laser cut) available. He may chime in here... those are good aircraft as well.
If you do not mind not having wheels, try a Magnum. The USA distributor has them on sale for $99, and you can also buy a combo deal with a West 50 and pipe for about $350

The Diamond Dust is a fun plane when properly set up. Loads of information in this forum on various examples of that aircraft and setup specs.
