Review by: Slope FlyerCircle Dancer 2000 RES E ARTF
Assembly work is completed with the mechanism, power train installed and linkage! Since the tail plane is very light, so the CG is 80mm and ADH300L + folding prop 8''x4''Graupner + 3S450mAh but + 5g counterweight on the tail. It is a nice flight with a 2S1000mAh is also OK. Speaking of force, the tail is light, so I think that the stabilizer can be reinforced.
Review by: Colin LeighfieldExcellent build quality.
It looks promising. The only problem I had was finding that the (carbon fibre?) dihedral braces/wing joiners would not fit into the wing boxes and needed some careful filing and sanding before they would easily slide in.
Review by: Graham LorimerFlying the Circle Dancer Electric
I bought the ARTF Circle Dancer as a Back Up for my Purito Electric, and today was the second day of trimming flights. I had already spent an hour or two trimming it a couple of weeks ago, but the only way to stay in lift seemed to be "Flying Ugly" as I would call it, nothing smooth about this one at all. Stalls were quite common and very hard to dial out, I found I had to fly it all the way even in good lift.
Several flights in today, I snagged some reasonable lift and got away nicely after spending over 4 minutes at less than launch height of 60 meters. With a maximum altitude reached of just over 525 meters, I ended with a flight of 42 minutes 41 seconds. After a lot of rude comments, plus a couple of good suggestions from the watching F5J guys, I started moving the C of G further forward, and a lot of the "Flying Ugly" was dialled out, I suspect if I had flown in the good lift with the new settings, it may have been even better, so now the Circle Dancer has been elevated from back up model to equal Number One Status with the Purito.
I will put it on the C of G Gauge tomorrow and see where it has ended up. A very nice model, but very different to the Purito.
Comment by: Slope FlyerA week balsa structure horizontal- stabilizer.
It needs some reinforcement for the soft balsa structure horizontal stabilizer! I think that it need the combination a vertical balsa wood and a side grain balsa wood to build the stab. I think it is better to bury 1mm carbon rod near the leading and trailing both sides edge of the stab. it needs device to linkage rod with horn size as you can possible. Because it is not smooth action. I changed the linkage for DLG music wire & bondable tube with white tube included this model. Also, as always with hyperflight shipments, it arrived in the Japan quickly, well packaged, and without damage.
Review by: cstaatsoregonCircle Dancer 2000 RES
This is a competitive F3-RES sailplane. Please note: due to the composite boom fairing, and the fin mount, some CDs may not allow this sailplane in their F3-RES events. Our club sees these as "non-performance enhancing" items, so it is not an issue at our contests. Check with your local CD. I purchased the ARF version of this sailplane, which was well constructed, with a very nice covering job. Only a few hours were needed to assemble and install the radio gear. This model launches high, floats well, is good at signaling lift, and still able to penetrate wind effectively without adding ballast. FYI, I did need to move the CG forward of recommended CG range to get the best overall performance from this model. Also, as always with hyperflight shipments, it arrived in the US quickly, well packaged, and without damage.

Package arrived promptly, and in perfect condition. What a beautiful model. Wish I could apprentice with those guys!
