Weasel Trek

Paid for my weasel and it arrived one day later. I installed an Alula flight pack after modifying the battery hole so it fitted right up to the nose and super glued two bluebird 101hv servos in place. It took a bit of lead to get the balance point correct but my completed Weasel was nice and light.
Took it to crown hill for a test flight in 5mph wind and it flew perfectly first time, brilliant fun, I love scratchy conditions. The wind increased to about 10 mph and it flew really well, looping, rolling and gaining height very quickly in the smallest thermal.
Better than the Alula in my opinion but they both seem a bit expensive for a small flying wing foamie, well developed design though.
Tip: Spend some time setting up the control surface movements, C of G and exponential EXACTLY as it says in the instructions.

Weasel Trek

Much improved on original version, easy to put together and as long as C of G is accurately obtained, performs very well. First flights in 20 mph winds and performed well with and without ballast. Important to keep elevator throws low initialy and I find about 20% expotential on both controls helps.
Would have liked some bright decals but otherwise great value.

Great Flier

Excellent in flight and great fun, but disappointed that the decals aren't included. A bit pricey for what comes in the box.

Most Excellent!

After many years' absence from the slopes I turned to Hyperflight for guidance and to the Weasel Trek (WT) as the Ďbest betí for my return: I'm glad I did. Hyperflight's service was swift and impeccable and Neil's patient and professional guidance on NIMH batteries was invaluable - many thanks. To summarise my experience with the WT - it assembled quickly and easily, the mouldings and accessories were faultless, it copes splendidly in light and strong winds and can fly both gracefully and with amazing agility. Excellent value! For more detail, read on.

Following the clear WT manual exactly in all but the control throws (more on this later) I assembled the wee beastie in under an hour. The recommended Dream Flight servos and battery fit perfectly. The Spektrum AR400 receiver (which has top connectors) fits with room to spare. With the C of G adjusted to the marks under the wing, and the elevons centred, the WT flew perfectly from the first chuck. I then flew it comfortably, without ballast, in winds from 6kt to 20kt, gaining height easily in the lulls and penetrating well at 20kt. Improvising a 47gram ballast weight (from ten pennies wrapped in sufficient masking tape for a tight push-fit into the ballast bay), I tried this in winds over 15kt: it improved penetration noticeably and did not dislodge during aerobatics. The manual suggests control throw values to suit both the fearless and the timid. I set-up 3 Control Rates beginning with slightly less deflection than the recommended Low Rate. By trial and error I then set 2 further (more thrilling) rates - the higher of which applies slightly less deflection than the manual's recommended High Rate. I also applied 15% exponential to all axes. In practice my low rate setting is restful and appropriately gentle when curious Red Kites fly alongside but aerobatics are slow; I use my mid-rates for basic aerobatics whilst my little-used high rates remind me of a bluebottle twizzling against a window. Using my mid-rates, tight loops and fast aileron rolls are easy but airspeed diminishes very quickly. Bigger, graceful loops and slow axial rolls look nicer and maintain airspeed better. Spins are straightforward and stable, with a brisk rotation rate; recovery is just a matter of centring the stick. I even tried DLGing my WT on a calm day - it was not a great success (I should have eaten a bigger breakfast).

Love it

The Weazel is my go to slope soarer for all weather conditions and i'm so glad i bought it. The kit is high quality, goes together in about 30mins and flys perfect. I love carving out tight grooves and turns on the slope. So far I've flown it in 6mph - 25mph winds without issue. There's a handy ballest box under the fuselage. It's had a few less than perfect landings but it's still completely fine with no issues....Just get one!!

Superb slope delight

I have previously flown the Elf, Vagabond, and the Alula and having thoroughly enjoyed the alula's portability I required NO motivation to buy this. I maidened it today at Butser hill and found it the perfect all-rounder. It is much more stable and much better at penetrating. It thermalled superbly and was able to handle a good variety of wind envelopes. My only issue is mastering launching it successfully without it dipping down - something to trim. But easy build, and great service as always from the Hyperflight site and Neil. Thanks.

Weasel Trek - Ideal travelling companion

Bought the Weasel Trek because of its ability to be broken down into a few components and left in its box for easy light transport in my backpack. Together with my TX in a hard case I can get to all those difficult and challenging flying site that I would not normally fly at. I took my Weasel Trek to Wales on my hols. Flew it on the beach and on the sand dunes and then up on Pen-Y-Fan (886m high) and then off to Rhossili. The model is fabulous. Goes together in minutes and you are ready to fly in a jiffy. I flew mine in 5 mph winds and also in 20mph winds. It floats along in light lift but up on Rhossili with the stronger winds it penetrated well (without any ballast) and proved itself to be a superb all rounder. I purchased the stock servo's and battery from the here and as usual the service from the Hyperflight guys was 1st rate.
I am a big fan of this little model and It will open up a lot more flying sites to me in the future.
If you are Interested then I have some video of my Weasel Trek flying in Wales for you to watch on my blog: http://slopesoaringsussex.blogspot.co.uk/ or my Youtube channel: https://www.youtube.com/channel/UCOI88Pb9F9sJAvKBbKzSKXw

Weasel-Trek

I got the Weasel-Trek to replace an ancient and much battered Weasel-Evo. The new magnet construction system makes it a lot easier and faster to put together but, as on the Evo version, the CG position is critical. I balanced it as recommended, on the two marks under the centre section and it was as twitchy as hell! I was getting quite frustrated with bouncing it off the hillside and trying less and less control inputs until I added about 15g of lead in front of the battery. It then behaved as good as the Evo version. Funny in the at the Trek has the CG about 5mm in front of the recommended position whilst my Evo has it 5mm behind. Control throws are now as recommended on both versions and I can throw them around the slope with abandon!

Another Dreamflight Success

Having "built" and flown the other Dreamflight models the Weasel Trek is another very easy to build and enjoyable to fly model. My model balanced on the recommended CG marks without adding any ballast, the flying was very easy and smooth with loops and rolls no problem. The model flys quite fast downwind and when positioned into wind it will just hang in the sky on the prevailing wind. My only gripe is as mentioned by others I wish Dreamflight would include some more decorative decals just to brighten the sterile white foam. I used Solartrim sticky film to add a bit of colour and this also helps aid orientation. In a nutshell recommended.

Never had a flying wing before. Very easy to put together, used dream flights recommended servos and battery which no doubt helped. Maiden flight was uneventful set up on the high rates as per the manual, in fact (just my personal preference) I dialled in more elevator. I found I preferred a rearward CG. Next flight was literally a hoot, this thing will do ridiculous manoeuvres and its great fun to fly. I was curious to see if this was "For all levels of pilot" I have a friend who's interested in taking up flying, on low rates granted he crashed and burned a few times he can now do a few circuits on the local slope. Highly recommended.

Weasel-Trek

Really worth the money (even though it is just a slab of foam). Fantasic low wind performance. Californian excellence for those lazy summer days. (And I suspect winter days with ballast).

Tip: You can use any aerosols to paint, just keep the nozzle about two feet away and do several light coats. This allows the solvent to evaporate before it hits the foam. Too close / heavy and it will melt, so less is more.

Cracking little kit

The Weasel goes together very quickly and easily indeed. Adding the recommended servos and NiMH battery, along with your own favourite 4ch rx, is straightforward. The magnetic latching arrangement on the airframe works a treat, simplifying assembly no end.

How does it fly? Pretty darn good straight out of the box. I needed to add around 3gms to bring the CG back to where I preferred it, but that took only a few seconds to organise. The Weasel is extremely manouverable, but will still hang in there on only a sniff of an updraft. Haven't tried ballasting it yet for windier days.

Overall I'm very pleased with this little flying wing, but wish there'd been a little more by way of decorative trim available - white foam isn't that visually appealing, is it?


 Review by:

The new Weasel Trek was definitely worth waiting for, although when you open the box it doesnít seem much for your hundred quid. Having said that, the finish is superb, everything fits together perfectly and itís all assembled (bar the electric bits) in about ten seconds.
When I ordered at the beginning of May, Hyperflightís original estimated dispatch date was 10th May but that slipped to 31st. It arrived on 2nd June (Thursday) and by that time Iíd ordered two Gening D90 digital metal geared servos (£7.50 each Ė how do they do that?), a Frsky 4 channel receiver and a four-square pack of AAA Eneloops. The servos didnít quite fit the recesses but itís an easy job to deepen them a bit and widen the grooves for the lugs. Thereís plenty of room for the receiver and the rest of the installation is dead easy. Dreamflight supply some decals but it comes all white: the colour is added with parcel tape (left over from Zagis) and/or spray paint Ė Humbrol acrylic worked well, but do as they say and clean the surface well with meths first. The servos arrived on Saturday lunchtime, and it was all done by the afternoon. I used the control throws recommended in the instructions, with dual rates on the elevator and ailerons.
One minor problem I did find was that a couple of the magnets that hold things together fell off. I fixed them back on with epoxy rather than cyano, hoping that would give a better bond: so far, so good.
Installation complete, the test flight was on the Sunday, but the wind was light and swinging around easterly, which in this part of the world means a small slope at Rodborough Common, near Stroud. The c.g. was set on the two moulded-in markers, which needed about a 10 mm square of lead flashing beside the battery. It flew straight off the launch with just a touch of down trim, but not for long as the lift was not really up to it. Iíve flown it in much better conditions since then, and taken out some of the lead, and itís now about neutral, which means it flies inverted with almost no down elevator. I never owned the previous version but Iíve flown other peopleís, and the new one flies like any Weasel but better (have to say that). The roll rate is snappy and it will loop, bunt and all the other things you can do without a rudder.
If you like to experiment, I would recommend increasing the elevator throws from 10 mm (Dreamflightís high setting) to about 25 mm, or the maximum the servos will allow. I now have that on a third rate switch position so itís low, high and stupid. With that, it will stop in mid-air, or if applied slowly it will enter a deep stall and come down like a parachute. You can keep it straight with aileron, but it will spin if you let it. More experiments will no doubt follow. 40% exponential on elevator and ailerons seems to work with all the rates.
Conclusion: highly recommended, great fun but a bit pricey. We pay the same number of pounds as the Americans do dollars.
