EDIC-WG approved Sidus EL energy limiter for the FAI F1Q class

I am pleased to inform all interested modelers that the Sidus EL energy limiter for the FAI F1Q class has finally been approved by the EDIC working group.

During the process a new technical requirement was recommended for F1QELs which consists in the immunity of the device to stray or static magnetic fields induced by the motor magnets or by power cables in the immediate vicinity of the current sensor.

The need to fully comply with this important requirement, unfortunately does not allow existing Sidus EL limiters to be brought into conformity with just a firmware update.

The new EDIC approved Sidus EL limiters come with the new V4.0 firmware and have identical dimensions, connections, weight, way of use and price compared to the previous ones. They should be available in early February.

In case of doubts or questions, please email

Thanks for the attention.




Nelson Glow Plugs /  F1J Carbon Tailbooms for Sale

I will have Nelson glow plugs for sale at the Fab Feb week of events.  The cost is $8 each.  So far, I have one order for 30 plugs and will have extra on hand.  If some flyer needs a large amount, please let me know so they can be preordered before the Fab Feb week begins.

Also, I will have carbon 1/2A / F1J / F1P tailbooms for sale.  These have been manufactured by Stepan Stefanchuk in the Ukraine.  They are a replacement for the aluminum / carbon / aluminum Ken Oliver tailbooms from the past.  The weight is approximately 20 grams.  The big end diameter is 1.080 inches the small end is .300 diameter and the length is 38 inches.  The cost is forty dollars per tailboom.  I can also mail these to anybody who wishes to purchase them.

Where is Lost Hills

We got a question from a European Sportsman planning and entered  to attend the Fab Feb events asking how to get there.

The web site is and it has maps and lots of other helpful information

We realized that we had not published the contest flyer for the Isaacson Winter Classic that is at the same weekend as the Kiwi Cup – so here it is

Small Print section

For the mass launch events the exact launch time of each event will be given later*
The E-36 Mass launch will be coordinated with the first round of F1S (which may be delayed if there is a long Kiwi Cup  flyoff on Sunday AM )**

HLG and CLG  National Cup Points.  These events will be flown from the Glider Pen and there will an additional special award for these events : Strong Arm  Glider Challenge.  This is  the overall winner of the aggregate results of the HLG and CLG classes. Points are awarded for the place in the event. This means first will get 1 , second 2 , etc. If a person does not fly in one of the events, for the purposes of this their points will be one more than the number of people in the event. The winner is person with the least number of points.  This award is open to flyers of all age categories.  There is an additional prize for the top Youth flyer.. This is for all youth flyers in the same categories , there is a small difference in that half points are awarded for the  CLG class, making this class more important as there are more youth flyers in this category.  For both awards if there is a tie it will be decided by the sum of all the times. Double times for CLG in the youth category.

Golden Age:  Any post NOS design published, kitted or flown competitively between 1 Jan 1957 and 31 Dec 1969 scaled if needed to 1/2 A size, powered by either Holland Hornet 049-051 or Cox TD 049-051.  Construction must replicate the original design, no carbon fiber to be used in construction.  NOS flight rules.   Gas powered only for this award.

Vintage FAI :  5 flights, no rounds, First flight before 9 A.M. will be timed to the ground, that time will be used as a tie breaker if a tie persists after two regular flyoff rounds.  Flyoffs if needed will be scheduled for 1 P.M.  Flyoff type. longer flights vs shorter engine runs will be determined by the consensus of the fliers involved and weather conditions at the time.  Era specification and engine runs per NFFS

Combined events will be separated for National Cup points. AMA gas events will be determined AMA vs Classic when registered for National Cup.

Glenn Schneider is running the AMA events.

Rest of the story: As most of you know Norm Furutani, one of the founders of this event retired from running it after  the 2018 event.  This event is very popular along with the FAI events.   Glenn Schneider has offered to run the AMA events with a number of volunteers.  This is very much appreciated by me and by those who want to take part.  We have tried to maintain the spirit of the event. Popular events with the largest participation are the HLG and CLG,  Gollywock, E-36, Vintage FAI and Nos Rubber.  At the Winter Classic in the past we have promoted special events, typically boosted by some donated $ in the prize money.  This year we have the Golden Age ½ A Gas models.

Most of the people who have offered to help are AMA/Nos gas flyers. Glenn can probably do with some help, particularly on Saturday from some with electric, glider or rubber model experience.
