There will be an opportunity to discuss EMFSO Formosa Racing in 2013 at the January Workshop.

Good evening, Clair.

I seem to recall that there was a maximum weight for the lipo batteries last year.

So, is there no limit for the lipo packs, subject to the maximum airframe weight?

Also, what is the typical capacity of the battery packs for the various classes?

Yes, there was a maximum battery size in 2012, but in an effort to simplify Formosa Racing for 2013, battery weight is pilot's choice.

Quote

Correct, there are no limitations for battery packs other than 2 or 3 cells depending on class of Formosa racer. Also, there is no maximum weight for Formosa airframes except for Formosa Brushed class racers.
Quote
Also, what is the typical capacity of the battery packs for the various classes?
Suggested battery packs are: 3 cell 1300 mAh or 1350 mAh; 2 cell 850 mAh up to 1300 mAh.

Thank you for asking some relevant questions.

Actually, more along the lines of whether or not what I was planning to order in the way of whether or not the lipos were going to be for a single aircraft or something that could be used on multiple aircraft.  The 1350mah-3s packs look to be good -- the parkflyers on the building board plus the Cub take the same size so that makes buying packs easier.

Just have to lay in a supply of the brushless motors and speed controllers.......

Bought too many single-plane lipo packs in the past.

Scaleguy, the AGM is coming up in three weeks' time and these are perfect questions to ask since the rules are on the agenda.
http://emfso.org/smf/index.php?topic=3203.0

General reference for the Formosa is http://www.eflightwiki.com/eflightwiki/index.php?title=GWS_Formosa


Personal opinion only.....
1) Spars are required but CF versus FG versus ???? is not specified. According to the GWS Formosa II manual, the spar rod is carbon fibre. If you're building one of the old kits (lighter but not EPP foam), the spar rod is fibreglass and replacing it with CF would be within the rules.
2) Motor choices. Hmmmm.... I suspect that the short list is to keep the playing field level, but if you have a side-by-side comparison of the motors and they are exactly the same, then I suspect that it may be allowed (my opinion only, but then, I just bought three RC-Timer 2212/6 2200 KV motors.....

Hi Bruce,

At the OMFC meeting Clair specified spruce tapperd spars.  I had assumed there were no spars in the original kit hence the spruce ones.  If FG spars are included with kit then yeah I don't see why CF would be disalowed if their are no weight restrictions.  CF will be way stronger then spruce.

I only ask because we are cunducting a workshop next Saturday for Formasa building.  I gues I don't need a power plant locked in yet for the build.

Why the RC-Timer motor over the Turnigy and do you have a link?

Clair can you give me the dimensions for the spruce spar as you suggested to come with one made for Saturday.

Jim,

The Turnigy Aerodrive D2826/6 2200KV, RC Timer BC-2212/6 2200KV and RC Timer  BC-2826/6 2200KV are essentially the same electric motor. All three motors run on either 2 cell or 3 cell batteries. The motors are powerful, well rated and inexpensive... a terrific combination for entry level pylon racing.

A review process starts after each race season. After the 2012 race season, the review included, one on one discussion, a Formosa Race Workshop, online information and EMFSO Forum discussion. In the near future, the specifications for Formosa Racing 2013 should be finalized at the Annual General Meeting February 13, 2013. Stay tuned.

Participation is encouraged in both the 400 and the 500 classes of Formosa pylon racing. The 2 cell 400 class is entry level, slower and requires race strategy The 3 cell 500 class is faster, requires a better set up and more demanding race technique. At a race event, some participants use the 400 class as a warm up for the faster 500 class racing. One model and two race classes... plenty of participation and race action for racers who like a challenge. All participants receive points for each race. For example, 4 points for first, 3 points for second and so on. Race participants in both classes accumulate points and for those who race in both classes there is recognition for overall achievement. Formosa pylon racing emphasizes participation, low cost and entry level competition in a friendly atmosphere.

Thanks for the posting your questions.

Regards,

Clair

Jim,

Thanks again for the great questions about the Formosa Racer.

At the OMFC meeting, a tapered spruce spar was referenced because it is a low cost option that is stronger than the solid plastic rod included in the Formosa EPO kit. Carbon fiber is another option for the spar.

A small supply of electric race motors will be available at the Saturday Workshop. Two Formosa EPO kits will also be available.

The link to the RC Timer 2826-6 2200 KV is http://www.rctimer.com/index.php?gOo=goods_search_list.dwt&gcat=45&gkey=&image.x=4&image.y=8 . Shipping is included with the RC Timer motor.

The stock required to make a tapered wooden spar is 1/8 inch x 3/8 inch x 19 inches in length. Some builders who want a slightly longer spar use a 20 or 21 inch length. Consider using spruce.

I hope this post is helpful.

Regards,

Clair

Clair,

Thanks for the info, links and dimensions for the spar.

I bought a kit from Hobby Hobby on Sunday, I hope it is the right one.  All that was listed on GWS site was Formosa & Formosa II.  Are both those the EPO Foam models.  I bought a Formosa NPS verssion which i assumes stands for No Power Syste.  The kit was $39.99.  Ymmm I think I'll go CF spar over spruce so I'll crack the kit open and get the appropriate dia CF Hollow Tube.

See you this coming Saturday.  Any idea on the cost of the motors that will be there on Saturday?

Regards,

Jim

Hola, Jim!  The newer kits use a different foam (EPP versus the original EPO, I think) so the new ones weigh slightly more.  The rules take this difference into consideration IIRC.

One of last year's rules threads discussed the foam and weight differences.
http://emfso.org/smf/index.php?topic=2910.msg13745#msg13745

I don't seem to recall any significangt difference between the Formosa and the FOrmosa II kits -- might be the transition to the foam. Clair's been building the Formosa's much more than I've done, so my comments are my opinion only.

Who keeps track of who has what Race Number? 

I assume we attempt to avoid duplication?

Is there a Master List somewhere I can check?

See you this coming Saturday. Let's get ready to build and then race.  Any idea on the cost of the motors that will be there on Saturday? $15.00 each.

Regards,

Jim
