Afordable F5B airframes for North American Flyers

I congratulate Dieter on investigating the possiblilty of bring back some of the earlier Surprise designs (S-5 & S-6) at more afordable prices ($500-600). http://www.rcgroups.com/forums/showthread.php?t=283297

I just want new North American F5B flyers to be aware of some other options in the $500 to $600 range.

http://www.modelairpol.com offers the older Polish F5B design, Victor, at the above price point (or less?). They are also about to release their new F5B design, the Viggor. Soholingo has made several posts on the Victor in this forum.

http://www.electricedgemodels.com offers the Raketenwurm in a competition layup for $600 and a sport layup for $500. This is the previous design and not the newest version that Wolf flew at the worlds. The newer design with the high aspect ratio wings is rumored to be available in February.

Pushing above the $600 barrier opens up even more options including the Lea's that Dieter brings in, the Avioniks that Electric Edge Models and ICARE bring in, and of course the newer Surprise designs from Dieter.

Good stuff Don...

As we find more good bargains, we should post them here...

Sells the caleb and the weasel. Although the caleb 's quality control is suspect, I have heard very good things about the Weasel (this is another plane I would like to see in person).

Check out the new Sunracer from Soaring USA-- talk about a very nice BUDGET F5D type of plane!! It will definitely get you started in pylon practice without a big investment!! IMHO!

In the F5B class-- they have the Zoom-- and the Weasel--other good entry levels without breaking the bank!

I'm getting a little heartburn, too many people in my opinion confuse hotliners with F5B airframes. There are a lot of nice hotliners, but few can really qualify as legal and reasonably competitive F5B airframes. When one talks of F5B, legal airframes are defined by the FAI.

Briefly (borrowing from UK F5B site http://www.f5b.co.uk )

True F5B models (according to the FAI) must weigh at least 2000g, have a NiCd or NiMH battery weighing no more than 1100g and it must not exceed a wing loading of 75g/dm2. For 2005, the major ammendments are as follows.

Minimum model weight without battery will be 900g.
Maximum size of cylindrical cells will be 24mm diameter and 45mm long.
Maximum number of cells will be 16.
Minimum surface area 26.66 dm2


Alot of sites that claim to sell F5B models, are really selling what I would consider 10 cell hotliners. These 10 cell hotliners often do not legally fit into the provisional FAI 10 cell class because of having too little wing area.

F5F or F5B/10 (FAI provisional class) are the same rules as F5B except they are powered by 10 NiCd or NiMH cells, have a wing area of at least 36md2, and ready to fly weighs at least 1500g.

When I started this thread, I was thinking of true F5B airframes capable of using a 16-cell battery pack. But in retrospect, I am also interested in legal F5F airframes.

Don, the Weasel looks to be a "legal" F5F airframe:

http://www.soaringusa.com/products/p...ategory_id=262

Although Bob's website indicates a wing area of 34dm2 (below the 36dm2), the FAI definition of wing area includes the area for both the wing and the stab. I believe if Bob checks again, the Weasle will qualify. As such, I would place the Weasle on the short list of lower priced F5F airframes.

(someone should pass word to him!)

I agree, but the Zoom on his web site http://www.soaringusa.com/products/p...ategory_id=262
which is specifically is called a "F5B - Zoom 1.8M Race F5B" only has a wing area of 426 in^2 or 27.5 dm^2 is definitely undersize in area for F5B/10, yet only capable of carrying 10-12 cells.

See the confusion!

The Sirius has always been a good one, in my opinion. It's not the best quality, but it will carry 24 cells, and survives many a newcomers attempts at F5B.. I'm still very happy with mine..
I paid $200 for mine, but they've been sold @ $300 - still a deal..

I'd say the sport version would be precarious with more than 10-12 cells on board, but I don't see why the Race version couldn't take more. There's room for them, for sure.

Hi,

I have a friend in Poland - Jan Ochman. He is member of the polish F5B team and he builds the Raketenwurm from Wolf´s Fickenscher molds. He is often on various european contests, so you normally can buy or order a Raketenwurm there. The models are build with a kevlar fuse and carbon wings so you can get a competetive plane with a competetive wieght. If you will search the forum for the F5B championship´s in York, you will find some photos with Jan. (http://www.rcgroups.com/forums/showt...ghlight=ochman) In Europe the aviability of cheap molded models is so good becouse Poland, Czech Republic, and Slovakia are so close, and the shipment within europe is much less than to the US.
The main problem with sending the models to the US are the costs for the shipment. Its´s about 200$ for a parcel. The parcel is quite large and therefore expensive. But if someone in the US would organize an aggregated order for about 10 models the shipment will be about 20-30 $ for each model. If you add the shipment within the US, it will be still a price similar to what you have to pay for a F5B ship here in europe if you go to a contest. The only thing there must be someone "over there" who will organize it :-)

They no longer need to weigh 2000 minimum, and battery weight is free too...

These have a different name, but some of them are the same plane (aktivist and kaskadeur) :

That would be the Raketenwurm 2, not yet the high aspect ratio model I think...(2B)
