Description

The Flipper DLG is a new 1.25m (49") discus launched glider with the performance of a model costing much more. It is an excellent stepping stone to 1.5m DLGs from entry level models. In addition to making a great flat field flier the Flipper makes a very good small slope soarer, with great agility and a good speed range.

The fuselage is a nice carbon molding with a large pod and a big hatch for easy installation of the RC. It is recommended that all four servos are installed in the pod, to eliminate the need for noseweight. The fuselage is a one piece design

The flying surfaces are all spread carbon over solid core molded foam, with excellent workmanship. The fin is lightweight SC over foam structure and incorporates a tubular front part, to mate with the fuselage tailboom, for easy and accurate construction. The tailplane (horizontal stabiliser) is of similar construction to the fin, and is mounted on a short pylon above the tailboom. The wing is very well made, with a strong yet lightweight spread carbon skin with a high gloss finish and attractive very visible colour schemes. The supplied accessories include a throwing blade, all control horns, and pushrods.

Sorry, a build manual is not included. However this build thread has useful build photos of its larger sibling.

Great plane

Have had a few flights on this since buying, and am getting 30m+ launches with a bit of practice. It's a bit quicker in the air than I was expecting, but slows nicely.

AUW was 208g with 17g 2s, 4x BMS101 and 20g of nose weight to balance. Perhaps without epoxy for glueing the tail it could have been lighter.

The installation is a bit fiddly and unfortunately I put two cracks in the pod, as it is weak where you have edges and corners. After applying some 60g tow I've made it much more solid and only a few grams heavier now.

Overall a great model to get into DLG, but the kit is basic and needs quite a bit of thought to build up well. Certainly for any future DLGs I'll make sure its a nosecone design for easier access.

Great flyer though, I get 60s flights from 25-28m launch in flat air.

Addendum to previous reveiw by Richard

-One more thing I forgot to mention is that there were 2 balloons jammed into the the boom part of the fuse! I do mean jammed. One balloon was balled up and inside the other. I do know they can be used for bladder moulding but not one inside the other. I did manage to fish them out after hours of #^%^%(*() ! I take that to be more/other than just slovenly craftsmanship.

In the other post I meant the nuts for the bolts in the last item. :P

Caveat emptor 1 off sample

This has no reflection on Hyperflight, who have done their usual great job of shipping and handling.
Problems:
-The finish on the top starboard edge of the fuse is heavily marbled/orange peel. that can be sanded and polished but I feel I should not be required to do this.
-The both seams on the fuse from the wing saddle to the tail end have many pits or bubbles with no epoxy. Yes they can be filled and sanded but why by me?
-The stab pylon is 2 cm too long! The elevator can only travel to one side but not toward the boom. More unnecessary work and if you want to see the elevator horn it needs to be cut almost at the rear hold down screw. Its also very flimsy and must be carefully glue or the decalage will be way off requiring shimming the stab.
- the vertical/fin has a moulded part to receive the tail boom but it is a very sloppy fit. Great care will be needed to insure that it is straight.
- The bolts for the wing hold down screws seem to be attached by being covered by some material which has caused 2 problems; 1st there is only a 1 mm opening at the exit of the bolts which must be forced out of the way. I ran a 3mm-50 tap down to clean up the sloppy glue in the threads. This is also true of the Smile full size DLG. 2nd a piece of that material has drooped down such that it may not be possible to run the aileron control rod without finding some way to remove it.

It is XPS of some sort so no CA. The wings and tail look okay so far as far as finish is concerned. Yes you can see where the foam ends on the tails and the skins continue but that does not bother me. The wings are good with just a small amount of print through and some ghost of tooling marks though not as bad as the Stilletto Lift also from Hyperflight.

If these are not just a 1 off problem I would strongly suggest the Stilletto Lift/Hot also from Hyperflight. My sample of the Lift is without any of the mentioned issues of the Flipper. I have yet to fly either one thanks to the lock down. :(

Flipper 1.25mtr dlg

Glider came boxed and was well protected. Good quality product, great service. Only downside it is my first dlg and with no instructions I didnít have a clue on how to put it together, the threads on line for a first timer are not that great.

It was a very prompt response

I used HyperFlight for the first time - the product arrived with a very prompt response. I am satisfied with the goods I received. I flew for the first time quickly, it is a very nice aircraft. I will use HyperFlight again if I have the opportunity.

Flipper Maiden

Beautiful construction being all carbon. Used four SD100s on a carbon plate to establish metal rod lengths and carbon friendly Spectrum receiver. Overlander 450mah 2 cell fitted perfectly. No instructions but photos work ok. Had to use putty in front to balance at recommended C of G. Flew really well in near zero wind but felt slightly nose heavy so will remove putty and play around with C of G. Used Stiletto Lift throw settings which worked fine. Full flaps and it really slows on landing. Managed to hook one thermal and it took off! Brilliant for the price and next stage up from Elf.


 Review by:

the glider was received in a large well packed box a short time after ordering. The all carbon construction is of very good quality and incorporates details which are usually found on more expensive 1.5 dlg's, like the integrated mount for the vert stab and the nicely fabricated pylon for the hor stab mounting. The pod is quite spacious allowing for all four servos (sd100's) to be mounted flat in a row with lots of room for the Rx and a single cell 750 lipo in front. With that gear it did come out a bit tail heavy . As yet I have not had a test flight but looks like it will be a good flyer and very good value considered the quality.
