Eventually got a gap to get mine in the air. And it didnt come down!

Review by: Tom LeeCircle Dancer 3600 Electric
This kit is worth every penny! It is so beautifully made, strong and flys so well. I've fitted a variometer in mine and am amazed how she looses so little height in 'dead' air.
I've installed one of the recommended motors a Powerline Micro 1025/F5J and a GM 16x8 carbon folding prop.
Have a look at a very short video of one of my launches. The throttle was set at only around 70% but she has a phenomenal rate of climb.
With a 3s 1300ma lipo I have had to add a little tail weight but I am hoping a change to a smaller 1000ma lipo and repositioning I should be able to remove the tail weight.

This is an excellent aircraft. The construction is beautiful throughout. I have the White/Red full-house glider variant, which I have converted to electric. Visibility at height and distance is excellent. Converting from glider to electric has cost a few grams, so my AUW is about 1.8Kg. I used a direct drive brushless setup on a 10x6 the climb is near vertical at about 9.5m/s.

Great looking sailplane (arf kit) from a designer with an excellent reputation at an affordable price.
And thanks to Hyperflight for their excellent communication and prompt shipping.
Review by: Nigel BennettCircle Dancer 3600
I can't comment on the flying abilities of this E/S because I decided not to buy it after inspecting the parts.
All the moulding were of a very high quality, the fuselage being excellent.
However the tail plane and rudder were not as well made as the wing, and I thought rather too flexible. The wing was 42 gms heavier than advertised.
Probably quite a good model for sport flying but not of the same quality of detail design or construction as say an Ava or Pulsar. But the price reflects that.
First class service as usual from Hyperflight, with no quibbling about me cancelling the order.
Comment by: Iain Glitheroflying the circle dancer
The first flying trials were disappointing due to the lack of power from the motor, about 320W. I recommend about 400 Watts for good f5j or ALES climb rate. I put in a more powerful motor and because of a heavier motor/gearbox I needed to add 1oz to the tail to maintain a 102mm cg. I also increased the rudder throw to 45mm each way. The model now performs the way I was expecting and the fine tuning is in process.
Flying weight is now about 58oz.

I purchased this model from Neil for several reasons: I have always like Drela's design philosopy. It is the right size for ALES/F5J. It has the control surface configuration I prefer, REF, and the price is very reasonable for the size and type of model.
I bought this model in the UK and carried it back home to the USA on a comercial flight. With correct packing it survived the baggage handling process!!
When I examined the model it became obvious the this is a very well designed and executed model. All parts fit well, the wing joiners are MASSIVE but not heavy. The fiberglass work is superb and the covering is very well done. Such items as threaded inserts for wing, horizontal and vertical tails are all in place and my only comment here is that the bolts for the wing are too long! (Easy to fix).
It is refreshing to have servo covers for the flaps which auctally clear the servo arms easily.
I located the servos for Rudder and elevator under the canopy, and installed a geared Redfox Eco 400 motor with a 13X7 A-M folding prop, but the CG is 10mm too far forward. ( how often does that happen?) I am using a Hyperion 3S 1400mAh HV battery and I don't think I can go much lighter here.
I hope I do not need to add weight to the tail.
I intend to fly with the slightly forward CG and see how it handles to begin with.
AUW is 55oz.
