Indoor Technical Committee Objectives

The primary aim of any Technical Committee is to Promote, Protect and Preserve all aspects of their particular discipline, to ensure there is a sound foundation for future generations.

Indoor Duration in particular is especially vulnerable because of the lack of high ceiling sites in the UK and the almost impossible cost of hiring suitable venues. We have to be pro-active in our endeavours to see that we are not perceived as elitist and pander only to the competition fliers who are rarely seen in action by the general public.

It is imperative that the ITC get relevant informative articles into the BMFA News and other publications as often as possible, so that those interested can see continuity, follow events and hopefully give indoor duration flying a try.

We need to do all we can to cater for the sport fliers who will hopefully be tomorrow’s competitors. Every year we run Challenge events aimed at novice flyers. One such recent Challenge resulted in several new entrants to the field of competitive F1D flying as well as providing several others with much enjoyment in flying their new 35cm models. As a result we were able to run a year long mentoring programme which provided one to one indoor skills transfer. One of these mentees subsequently qualified for the National F1D team! We have also introduced a web site which aims to provide a single point of knowledge for all things involved in building duration models including:- wood selection, building, covering techniques, rubber motor preparation and of course flying. It also carries news regarding upcoming and recent events.

Indoor Introduction.

The aim of these pages is to provide information that is relevant to newcomers to indoor duration flying, ideally to be used in conjunction with our main website


Please note that if your interest lies with Radio Controlled indoor models then try searching on-line for:-

After a brief flirtation with microfilm covered indoor models in the early sixties I have flown outdoor RC models for most of the rest of my life. I came back indoors in 2009 following retirement and can honestly say I have not regretted one moment of it. The first of the links below tells you a little of what you need to know to get you into flying indoor duration models, the second covers my own new start.

Getting Started       New Beginnings


In Sports Halls across the country a surprising number of enthusiasts are enjoying the pleasure of flying indoor models, ranging from tiny scale ones to the large International Class duration models which can make flights of over 30 minutes - not bad on a rubber band!


The modellers themselves are very knowledgeable, incredibly friendly and more than willing to share their deep knowledge of all things related to indoor modelling with you. If you go to the website you will find many local groups listed – do give them a call or e:mail, they’ll be delighted to hear from you.


The models themselves are not incredibly difficult to make and can generally be made for a few pounds in 5 to 10 hours; of course the larger ones can take much longer than this - but you can have a good duration model ready to fly in very little time. We do, however, recognise that there are a number of  “barriers to entry” which, without individual help, can be quite off putting – go along to your nearest flying group, have a chat and see what they fly.


Our aim here is to provide you with the information you need to make a decision as to whether or not indoor flying might be for you and how to make a successful start. Once your model has flown for 5 minutes or so you’ll be hooked and ready to take the next steps along the road, you’ll also have made the necessary contacts to help you on your journey.


If you are interested then please contact me at and I’ll see if we can put you in touch with someone within travelling distance with whom you can discuss your interests and make a plan for creating that all important first model. The aim is to provide you with not only an experienced helping hand but someone who can help you out with a few of the specialist bits and pieces, wood selection, rubber etc. that makes those initial steps potentially so difficult for someone with limited indoor model building experience.

Here’s a couple of old books that still contain much useful information.

BMFA Forum papers

Thanks to Martin Dilly we have been able to extract several indoor items from the annual Free Flight Forum Reports, I can supply copies at £10 + Postage and Packing, all proceeds going to the Team Travel Fund. Among the interesting articles are these indispensable ones from Bob Bailey:-


  • How to make indoor propellers (2006)
  • Indoor Wood Testing (2008)




For the beginner there are 2 main introductory models flown around the country.

First of all the Gyminnie Cricket – an out and out beginners model for which see below for plans – but kits are also available from


Secondly the 35cm Entry level by Tony Hebb. Plan and Build Notes are available from the main  website.


I do hope that all this has been of some help to you, do let me know if you require any further assistance,
