Re: SEN 3327 aka the SEN B 4
From: GEORGE REINHART
Roger,
Pointing out the obvious, and in response to Dan Berry,
I can see some interesting possibilities that a 25gram motor presents.
More or less in order of complexity.
1. Do nothing but make the motor a little shorter and see what happens and maybe re-set the timer for a shorter run..
2. Same motor length but fewer strands and new blades to optimize for less torque.
3. Double length motor, smaller prop, for 90 second plus or minus run, the low drag, less energy loss option.
4. Complete redesign of fuselage, prop, motor, etc. to optimize the total package.
5. Better brains than mine will come up with more than these ideas.
6. Again, you could just pick a nice workable span limit as an alternative solution (an idea that nobody seems to like at all).
Cheers!, from a retired, over the hill curmudgeon, who still loves the sport.

How do I write for SEN ?
From:Marc MARILIER
Dear SEN editors,
Can you tell me if I can write a contribution regarding the reduce of F1B rubber weight ?
I’m a small french flyer comming back to F1B after retirement…
Best Regards,

Firstly apologies for the delay in getting back with a reply.
The way you write something for SEN is what you just did, send it in an email for [email protected].
It just has to be about Free Flight and a positive contribution. So go ahead Marc , your contribution is welcome.

Jim Hurst engines
From: Ted Hidinger
As many of you know my friend Jim Hurst went WEST, I have been given the opportunity to assist his brother in the disposal of Jims model airplane “stuff”, and believe me he had a LOT of it! My plan WAS to bring some engines, kits and complete models to the San Valeers contest, BUT due to having eye surgery that prevents me from going over the Grapevine (due to altitude) I will NOT be attending the contest – thus can’t bring the engines and other items. I will soon have a engine inventory list put together – he had over 500 engines, to that end I will respond to an email (only) requesting the list = [email protected] if you text or call I will NOT send it, it must be an email that’s the only way I can keep track of who wants one. The same thing with kits, he had a lot of them, will put a list together soon, if you want a copy email me requesting one. The complete models are something that I will NOT ship, to get one you will have to come to my house and pick it up or make arrangements with someone who lives near me to bring it to you, I have had a number of folks request a model (any one) of Jims, to that end I will honor their request, the ones that are left over will take photos of, if you want one will send you photos of those that are left. I didn’t plan on the eye surgery, had I not had it done the surgeon said I would have gone blind in my Right eye in less than a week.
Rules, Changes and Stuff
From: William East
Hello Roger
I thought I might throw my hat into the ring.
Sighting of models.
The question of watching the right model could be fixed by a device like we used in the F1C Babenko models. Basically, a High-definition LED bulb that can be seen by the Timekeeper who then can check numerous times during the course of the flight. I’m quite sure that innovators could quickly make an RDT type signal device to accomplish this.
Rules change
Logically in these days of high tech very expensive models that rules changes (in any particular category) be kept to within the basic specifications of that class, things like rubber weight or overall weight of the model (even though this is one of the spec criteria) would not require the flier to change his mode (apart from a new rear rubber post or weight “pod”. If major changes required a new model this could lead a path to what happened to F1C. Maybe change the rubber weight to 25g with the next step increasing the weight by increments of 50grams which in hindsight may be an idea for fly-off controls something akin to a fuse wire around a fuselage with a predetermined weight (say 50g) with a FAI security tag, this may sound a bit messy but ALL the models would be Equally “messy”. Just a thought.
