Last minute CD Update …

Roger please post in SEN
Sierra Cup update from CD – Couple of changes this year for Sierra Cup as a result of my move from CA to NV.  I will be living comfortably in my trailer until after Sierra Cup.  As a result there is no need to pre-enter and I will take entries at Lost Hills this year.  My phone for any questions is (916) 390-3212.  Look forward to seeing you for our endless October and our FAI finals.  Feel free to contact me by phone or Email @

Dino to a T
From: Michael Achterberg

There you go Jack.. F1t1… Electric F1c.. Now, you have an F1c replacement that will create a lot of interest in the power camp.. Models wont be complicated by fuel, vibrations and everyone will have same power source.
Clean and quiet and fly like a power model from the 90’s.. Sounds like the model we watched at the maxmen a few years ago..
There is a lot of interest in the venue, but getting something passed and then not changed is the problem.
Here is an idea…. Ask the power flyers for there input. Leave the glider and rubber guys
out of the discussion..  We don’t need another F1p event that replaced a perfect F1j event.. The designers of F1p event, with all good intentions, came up with a model that the juniors didn’t like, was way harder to fly and killed interest. They complained about excessive performance as a reason.  Lets see. Humm.. Anyone come up with the novel idea of cutting engine run down from 7 sec to 5sec. Wow, what a concept..
If you want a popular event such as your describing then ask the power people. Those still flying and those who just quit cause of last rule changes..
From Dino land….

Stop the wing moving …
From: Martin Dilly

Here’s something to raise a few hackles. In the World Championships classes we have some problems. Let me first echo CHE’s thoughts regarding the earlier person who “.. doesn’t care what the rest of the world is doing.”; … Like it or not, the clue is in that word ‘World’, – not US, not Californian, but /World/, so that’s how we need to look at it, blinkers off.

Let me touch on a few of the main problems we have in free flight (I believe ‘challenges’ or ‘opportunities’ are more popular words in spin doctor circles, but I’ll stick with ‘problems’, thanks).

1) There are far fewer flying sites available now for free flight. In many countries military airfields have closed or been returned to agriculture or used for housing. The few that remain are affected, certainly in the UK and doubtless elsewhere, by an ultra-sensitivity by those in authority to the remote possibility of risk. The fact that in the past century or so there has not been a problem with free-flight models is ignored by those concerned about bucks stopping with them and affecting their military career. It’s called ‘ownership of risk’.

2) There are fewer young people coming into the sport and those still flying are getting older; it’s probably fair to say that the majority are nearer 80 than 50. One result is that retrieving models is becoming harder for many; despite this, on one UK site the organisers apparently ban motorised retrieving!

3) The models used in the main F1 classes are expensive if bought and require some quite specialised equipment if built at home. At this stage someone usually reminds us that the World Champs are the Formula 1 of free flight and that isn’t cheap either. I don’t regard Formula 1 as a sport, but more of an advertising medium involving fast cars; it depends on sponsors, so let’s get that one out of the way. The fact remains that at present competing effectively in a World Championships class requires four models that may well cost upwards of a couple of thousand dollars each.

4) The performance of today’s models guarantees that they will fly outside most of the flying sites that are now available. OK, I know this probably doesn’t apply to Lost Hills and Mongolia, but most of us /_do care_/ about the rest of the world. We need models that /_can _/be flown in contests on most available sites, rather than those that certainly can’t.

5) There is one factor that has produced the major increase in model performance and that is variable incidence or camber for horizontal flying surfaces. This has enabled the bunt launch in F1A and it is this, rather than circle tow, which has effectively doubled the potential performance of gliders. In F1B v.i.t. and v.i.w. has tamed the power of today’s rubber and made 100 metres or so reachable to start the glide. In F1C today’s climb altitudes would be impossible without variable incidence or movable surfaces.

6) The aim for the proposed rule change is to enable those with current models to use them in future, though obviously with some major trim changes. What we don’t want is for current flyers to give up. At the same time we need to make FAI flying more accessible to more people who are currently put off, whether by cost, performance or, by extension, by retrieving difficulties resulting from long flights.

7) Simply put, I suggest that no change of camber or incidence of horizontal flying surfaces be allowed for F1A or F1B, apart from DT. I admit that for F1C no solution seems possible that doesn’t involve making at least some models obsolete, for instance folders. I expect some opposition from those selling electronics and widgets involved with current technology (sorry, Roger!), and from those who will tell us that you can’t stop progress or un-invent stuff.

Standby for incoming…

Electronic Timer 4 AMA gas

From: Mike Richardson

Morning Roger,

In the SEN 2179 Ted Hidinger is looking for a electronic timer for large gas models. Dick Covalt in Anderson, Indiana has been fabricating just the thing for the past 5 years or so. He can be contacted at
I cannot find a contact for Ted so if you could pass this info on to him or give me his email I will contact him.

I just have to say, I love the F1Q posts. Conversations like these always make me smile.
My older brother Marty flies Q and even won the Nats last year. Not bad considering this was his first Q contest. He was flies a low performance John Oldenkamp design that kept breaking apart but thanks to CA and clear packing tape he achieved a clean card and won the fly off. His advantage was the 40 second allotted motor run. Which he did not take advantage of, due to the timer could not be programmed longer than 28 seconds.
This year Nats he changed to a different timer which turned out to be a disaster due to programming problems but all was saved thanks to Dick Ivers and Drake Hook. But Marty chose only to use a 35 second motor run, he was afraid of the model leaving the field. As for why he didn’t place in the top 3 you ask. Well, he missed a round because he couldn’t get a fresh battery loaded in time.
Dick and Aram are on the right track about using a F1B design. As for myself, I’m going the old school route. Or should I say, the poor mans route. Also less things to go wrong.

Later my friend,
Mike Richardson
