Jon,

Liked your article on F1A. I've been having very similar thoughts but from the view of a non-retired geezer. I've always built my own model using parts from other where my skills aren't as good as others. I would love to build a flapper but not sure I could, and even if I did I would have few opportunities to fly them - all very disappointing when I get to places like Lost Hills when the best innovations can be tested and perfected and my 'classic' models are shown up to be the tat they are. But what's this ? A new concept with simple structure that even a Mac Bigot can build, hurrah !

I refer of course to LDS (low drag section) models that have shown, in the hands of Roland and Kimmo, that there is a alternative to the expensive flapper. Hey, even I've built one and whilst I accept it was seen to go horizontal more often than vertical, it will be trimmed, er, eventually. So the flapper is dead I tell you, DEAD. I predict that once the manufactures get tooled up (some already have) that there will be a step function in performance like circle hooks, composite wings, electronic timers and bunt launches have all brought, but at a (more) affordable level. As noted by others, it wont mean they will win all events as a 2 minute model in 4 minute air always beats a 4 minute model in 2 minute air.

I congratulate Brian Eggleston and others for not only doing the work on LDS but also making the data available in the public domain. The CFD analysis certainly isn't trvial so gone are the days of designing section based on a size 9 plimsoll and we'll have to accept that new developments will be in the hands of a few - as they are at the moment to be fair. To be honest I think the next few yeras will be really exciting and I feel better about what F1A has to offer. And maybe as Mac retires he will consider building LDS models for those poor unfortunates still at work ?

EoB - Haggis Catcher to the Stars

Just to amplify Rick’s point [about a simpler class F1A], I suggested exactly the same thing in 1992 (see NFFS Free Flight Digest  April 1992 ) and was savaged for it (Free Flight Digest July 1992).  My suggestion was simple:  F1A numbers with automation limited to a 2-position autorudder, DT timer and a locator transmitter or audio beeper for model recovery.  Twenty years ago my knees were OK for towing gliders, today not so good.  So now I launch my gliders with a Hi-Start, or electric motor and folding propellor, and retrieve them with a radio control system.   Opportunities lost forever…

To understand better why I do have a déjà vu with the current discussion.

Each of the named chances in F1A (think the timing is quite right) caused a discussion

bout the introduction for a new “simpler” class because F1A was becoming too difficult!

Such a discussion never ever was started by the front-runners; people who always try harder to innovate …….

F.y.i.  

I stopped flying F1A cause of physical aspects (eyesight)

Mid seventies:                                                  introduction of circle towing                                     

End seventies –  beginning eighties          introduction of zoom launching

Eighties and early nineties                           structural changes – higher zoom launches

Mid-end nineties                                             introduction of bunt launching

Start-mid 2010                                                   introduction of electronics

The current discussion is a true Déjà Vu or is it just me ………………………..
