SuperbAhi is everything you need on the slope in one conveniently sized package.
Flies in the slightest breeze yet speeds up in an instant to make headway. Now I only need to take one plane to the hills.

Excellent as alwaysPurchased my Ahi from HyperFlight last week along with servos and battery as per Neil’s recommendation. Firstly the Ahi is so easy to put together it’s ready to fly in no time and the quality is great, no issues whatsoever excellent. I spend most of my time putting vinyl on it to brighten it up.
The Bluebird BMS-126WV servos that Neil recommended are excellent and fit in the plane a treat, centre well and powerful and a sane price. I’m sure I’ll have many flights with this and bags of fun.
HyperFlight has always been first class service, lots of really helpful advice and tips plus a really nice bloke. Cheers Neil excellent service as always 👍

Wow!What a fantastic model. Flies superb with amazing agility. Great fun :)
Review by: Marc Humphries
Great Service and amazing gliderI waited for ages to get the email notification that the Ahi was back in stock - and ordered immediately with the Hyperflight servo, battery and lead pack.
As ever - the parcel arrived in good time - but I was surprised to find that the box had not been wrapped and simply had the courier label stuck to the side. I found this odd - as it advertises to the world what it is.
Assembly was trouble free. The servo openings in the wings and fuselage tray need a bit of fettling. Control runs on the elevator and rudder were nice a free. I found an issue with the rudder and fin moulding - there is misalignment with the fuselage. So if I straighten the rudder at the tail end - it is out of line with the fuselage. Just looks odd, but you don't notice it in flight.
Just two sessions so far and I love the outrageous performance and still on a learning curve.
Would have been five stars but for the packaging and rudder issues.

Sticky snakesCurrently stalled on the build while I figure out a way to overcome the stiction in the snakes, particularly the elevator snake which is very stiff. It seems the problem is at the tail end near the exit. Otherwise the fit and finish is very good.
Review by: G Dale
Ahi reviewPretty glider, lovely kit quality. I put carbon rods along the leading edges to preserve the shape agains the rough and tumble of landing in undergrowth. Otherwise stock. Balance spot on. Easy to build, nice detailing and flies very well. Have yet to explore the envolope.
Review by: Brett
Delightful AhiAll went together in a straightforward manner using the supplied Dreamflight servos and battery pack. Only minor niggle was cleaning up the embedded elevator snake outer which had a small kink near its exit that introduced a little too much friction for comfort. After that it was plain sailing with the CG spot-on without additional weight.
Maiden flight was routine, needing only a couple of elevator clicks to achieve 'hands-off' balance in around 10mph breeze. A quick workout and boy is this model agile! A true delight to bring a huge smile to your face!
A little experimentation with the CG eventually returned me to the initial neutral setting as giving the best overall behaviour. Watch out for the elevator compensation if you decide to droop the ailerons in landing phase - the elevator needs 'up' dialling in, rather than the more usual 'down' associated with thermal gliders.
Also had the chance to try it out on small coastal cliffs/dunes, where it similarly offers great flying. Now to start practising those tricky right-up-close-in-your-face manouvres!
Overall, the Ahi is an absolute delight with the usual excellent service and delivery from Neil at Hyperflight.

AhiAssembly was straightforward, I used £2.49 Lidl pack of 4 AAA's, which fit, but not as well as the recommended battery, so I had to use a bit of glue to keep it in place. It came adrift inverted, fell out and took the canopy with it!
Flying looks promising so far - picks up the slightest bits of lift on the slope like a DLG would, but also happy in breeze - feels stable sitting up there, but very lively when you want it to be. I've now found that spoilerons really help with landings - it has a slippery shape and I've needed to slow it down to land on a couple of sites - it's not really a rough and tumble model!
I'm going to fit a better Rx - was using the basic 'Lemon' with a simple dipole aerial, yesterday we had a brief radio outage in flight, I wonder whether it was because the carbon canopy is right over the dipole. Will now use the 'Lemon' diversity Rx, 2 antennae which can be positioned away from the canopy.

AhiI'm returning to the slope for the Winter after a very long (nearly 40 years!) gap and was recommended the Ahi as a good way to get back to soaring. I ordered the plane on a Saturday while I was away from home and it was there to greet me the following Tuesday - so very quick service from Hyperflight. Assembly was very quick and easy and I'm just waiting for the opportunity to go out and fly it! The videos make me sure I have bought a good plane so I'll report back once I've flown.
Review by: Pete
Quality ModelI have yet to fly my Ahi as I am still setting it up. I am a slow precise builder/assembler and have just completed increasing the depth of the wing servo cut-outs to suit the servos I decided to use, adjusting the length of the servo leads, and enlarging the cut-outs in the servo tray.
I will be adding a small carbon rod to the leading edges and also to the tail skid.
I am impressed with the quality of the finish and design. It all fits together very well. I am looking forward to taking the Ahi to the slope where I am sure it will perform perfectly.
Review by: Seb
Another dreamflight hitI've loved the Alula and Weasel so had no fear in buying the Ahi. Still wonderfully simple to assemble. Maiden in lighter than ideal winds but still superb fun. It has an amazingly docile stall, floats on a whisper, and has great axial control. Really looking forward to experimenting with more aerial slope flying with this.

OMGWow what an unbelievable model this Ahi is, I used to fly for team GB in the world jet masters and came 2nd in the 1999 world champs so I would like to think I Know a bit about models and this little slope glider from out the box and being fully ready to fly 2 hours and on the hill the following day blew me away, I chucked it with bated breath thinking it won’t be as good as people say.........OMG blown away with how ace it is.

Dream-Flight AhiBeautifully manufactured. Easy to put together. Great service from Neil.
Haven't thrown it off a cliff yet as I'm a bit rusty - am practicing on my Dream-Flight Libelle...
Review by: Roger James
Goes together very quick with no hassle. First few flights proved a let down with a very sensitive elevator but after honing it cg wise and taming with expo its turned into a sweet flyer and very friendly acrobatic plane. The secret is to fly as near as you can to yourself hugging the slope as per the rc groups thread. I can see that is one that will go with me everywhere this year and am really looking forward to the sessions. Well worth the money
Review by: Gordon
AHI resolutionThere was a comment about the pushrods in their guide tubes binding slightly,this only happens where the tube bends inside the fuselage before exiting.I found a simple method to resolve,using a length of the thickest piano wire (std pushrods wire from model shop) that will push into the tube ,insert about 6-8 inches and leave overnight or longer,this straightens out the tube by straining against the foam and reduces the friction by about 80% +.
Hope this helps,brilliant versatile plane and so aerobatic on the slope.bought a second one.
Blue bird servos are good too,how they get the power and no backlash beats the rest also I now run on liposuction 2S , don’t use NIMH anymore.

Ahi First ImpressionsFirst class service from Neil and a first class model, beautifully made and a "dream" to build. not had a chance to fly yet only test glided at our flat field and flew as straight as an arrow, can't wait to get it up on our local slopes or beach.
Review by: Brian
AhiWished to practice more dareing aerobatic moves with a plane that if crashed would not be totalled. The Ahi is absolutely great for this. Is is great fun to fly and will complete moves that easily get out of trouble should you make a mistake. I have flown it in winds varying from 12 to 30. I prefer winds around 20 with lots of lift amd all this unballasted. A great fun plane
Review by: Kevin
Fantastic acrobatic sloperFantastic sloper and more acrobatic than anything else I have flown. Flys in very light winds to 20mph without any issue. One star deducted because I bought two and on both the tail / elevator is not square to the wing. I think there is a slight issue with the manufacturing or hyperflight got a bad batch. I'm about to buy a third from T9hobbysport to see if I can get a straight one.
Review by: Seán Bannister
AhiNot 5 stars because: The tailplane is not parallel to the wings. The problem appears to be wings not joining the fuselage at 90deg. Managed to twist the fuselage and achieve a true alignment.
substituted the 5mm dia carbon wing joiner with a 5mm dia steel joiner, adding 36g ballast conveniently.
Great design, predictable flying characteristics and fun to fly after 40 years away from the slope!
Thank you.
Review by: Mike S
I bought this as a first model to return to slope flying after a 25+ year lay-off and the maiden took place in 25mph winds! However, very impressed at how it coped un-ballasted and I look forward to flying it in lesser conditions. Also very impressed with the design and fit of the foam components.
Review by: KEN COBLE
Just get one fly's great, strong build, also the overlander 600mha batt from Neil gives way over 2hr flying time. Again great product and service from Hyperflight. would buy another. FLOWN IN 10MPH AND 25MPH no ballast does the book.
