IIFI Wychen 2026

[Stunthenk]

The organising team today sent out the invitation to the 2026 event in Wijchen, near Nijmegen. For those not included in the mailing, the text is:

Invitation to:
14th International Indoor Fly-In
14 and 15 November, 2026

We would like to invite you for the International Indoor Fly-In! Already going for its 14th edition. On the 14th and 15th of November, Wijchen will once again welcome indoor flyers from the international flying
community! 
 
The preliminary schedule for the event: 
Saturday 14 November 8.30-19.00 
Sunday 15 November 8.30-18.00

A detailed schedule will be provided beginning of November to the flyers that have entered. 
 
Location 
The hall we will use is the Arcus Sport centre, located just outside of Nijmegen in the town Wijchen. The characteristics of the hall are about 32 by 48 meters; height is nearly 12 meters. The ceiling is fairly
smooth. 
Address of the hall is Arcus sportcentrum, Campuslaan 14, 6602 HX Wijchen.
 
Contest 
We will be flying contests in several classes. The classes are: F1D, F1M, F1M small (Juniors), F1L, F1N (Indoor Glider), Sainte, F4D (Open scale rubber), F4E (Open scale electric/CO2), F4F (Peanut), Pistachio, Kit scale, Glider scale and Profile scale. 
Depending on the number of entries and the fact that we have a different hall and one day less we will probably not be flying the Glider Scale class. If we find time to fit it in, we will announce this timely. 
Electric and CO2 will be split into 2 different classes but flown under the name F4E. 
The judging rules used for the scale classes will be those written in the IIFI rulebook version 2024. These are based on older BMFA rules and those used in the past at Interscale. The duration rules will follow the standard FAI rules. Please check our social media for more details on the rules. We can also send them via email to you. Flying other types of models is of course allowed as well; in the definitive schedule there will be time allocated for this. There will also be plenty of time available for trimming and fun flying. 

The F1M small class is used in the Netherlands for juniors. Rules are similar to the standard F1M rules, with the only deviation being a limit of the wing chord to 160 mm. 
Please note that all duration classes will be flown on normal weight, full motors. This is the same as previous years. The minimum weight for Sainte in the Netherlands is 3 grams.

Number of models 
Similar to last year, we are using 1 model per class per flyer. With the exception of F4E where you can still enter 1 model in CO2 and 1 model in Electric. A difference for example with the UK Nationals, is that you can bring a spare model for each class. The concept is when you crash the model enlisted you can put in your reserve model. This will mean that all the earlier made flights will be taken out of the results and the remaining flights will be made with your reserve model. This can be done for all classes but only after deliberating with judges and CD. The choice you give us before the start of that round or the competition will be the final choice. If the models does not fly of you are having difficulty getting it to fly, this concept cannot be used to change models. In this way we hope to have less work with judging and more time to fly and also trim fly in between. More of this concept will be repeated in all the following bulletins.

Dutch Championships 
For the Dutch flyers we will also organize the Dutch Championship in the classes F1D, F1M, F1N and F4F. These classes will be flown under the same rules as used during the competition. More information about timing, rules and local rules can be found in appendix I. To become Dutch Champion, you need to be a member of the KNVVL, a resident of the Netherlands and must have a (FAI) license given by the KNVVL, the flyer needs to present this to the organisation. We need at least 5 Dutch flyers per class. 
Note: International competitors don't need to have a FAI license to compete at the regular contest.

Proxy flying 
It is possible in the Peanut and Pistachio class to send in your model for proxy flying. The entry fee for this is €15,- Please contact us for more details about this and how to arrange it. Naturally we will
use only experienced flyers to fly your models. Alternatively, you can agree with someone in advance to fly your models.

Prizes 
In all classes the best three flyers will receive a prize. For F4E the best three flyers in Electric will receive a price and also the best three flyers in CO2 will receive a prize.

Appendix I
In this appendix some important information about the competition can be found in a short summary

Timetable: 
Going back to one model per flyer and taking more time on the Friday we hope that flyers can get more  time to socialize and look at the other models. We will try to get more room in the timetable for trim
flying.  This all depends on how many of you are coming this year. So the sooner we now the faster we can  make a concept timetable.

1 model per flyer per class: 
Here you will find some examples about the reserve model concept. If there are any questions about this  please ask them. 
Example 1: 
You entered in F4D. Second round the model crashes and has damage (wing came off). You are given 2  choices. Either you repair the model for the last 2 rounds the next day or you go to CD and aks to put in  the reserve model. When the reserve model is put on the list the first 2 rounds will become a 0. The last  2 rounds will count for that model together with the static score for that model. If you have a real high  score for the first round you can also choose to put a 0 for the 3rd and 4th round so it will be added to the  results. 
Example 2: 
You entered in F4F. You already made 3 flights and the model crashes. You are given 2 choices.
Either  you repair the model for the remaining flights or you go to CD and aks to put in the reserve model. This  means the first 3 flights will be a 0 and remaining 6 flights will count for that model together with the static score. 
If a model won't fly because of trimming issues the concept does not apply. 

Timekeeping: 
Timekeeping wil be done in accordance with the FAI rules. 
For F1D, F1L, F1M, Sainte Formula and Profile Scale all flight times will be rounded to the nearest  second. .5 seconds will be rounded up 
For F1N all times are rounded to the nearest 1/10th of a second. 
For F4F and pistachio all the times will be rounded down to the nearest second. 
Local rule: We will use one timekeeper. For official national and international records the flyer is  responsible for a second timekeeper.
 
Dutch Championships: 
During the IIFI, the flyers that are residents of The Netherlands, get a chance to become Dutch  Champion in four classes F1D, F1M, F1N and F4F. Conditions to compete are: 
Flyer needs to be a member of the KNVVL. 
Flyer needs to present a (FAI) license given by the KNVVL for the year 2025.  Flyer needs to be a resident of the Netherlands. 
We need at least 5 dutch flyers per class. 
Local rule: There will be no difference between Junior and Senior flyers for the Dutch Championships.
 
!!!!International competitors don't need a FAI license to compete at the IIFI 2025!!!!

Hi Henk,

I cleaned you message up a bit, there was a dublication of the text.

Here is the original PDF as well. ( I can increase the permissible file size temporarily as the file is larger than normally allowed...)
