Simplex F1B hub available again
The original Simplex Reverse Montreal Hub designed by John Morrill is now available from Zephyr. These are the guys that make the compressed air motors. These would be just the thing for a low budget, simple F1B or big NOS Wake .
Also in their catalog are:
Tomy type d/t timer,
Torque meters for both indoor and outdoor. The outdoor come in 10, 20, 40 and 60 oz scales so would work for F1G and P-30.
A free wheel clutches for small rubber models
Quick release clamp for K&P winders
and of course the Compressed air motors and accessories.
Contact them at zephyrmodelmotors@gmail,com

Ross Jahnke Interesting comments so far. I had heard the energy anecdote at the Nats a few years back and thought it was a bit dubious. Tiffany, being the F1G champ has made me wonder if I shouldn't get some 1/16", if not a whole box.
I hope there is more input on this question, before it goes into the fb archive.
Lee Foster Campbell Tom; 1/4" rubber is no longer made. A year or two ago, John Clapp told me that the people who test the rubber were getting more energy from motors made up from smaller sizes. I still use 1/8" on every thing but the smaller models.
Rene Limberger You could get even more energy if you start describing the rubber width in metric units! Just saying.
Tony Mathews I've made motors from the same batch and segment of rubber from 1/8" and self stripped to 1/16". I got the same number of turns and torque in the several motors I tested. As Roger said, I've seen Alex A. fly with 1/8" rubber recently and I have got to think that if he thought he'd get more energy from 1/16" he'd be all over it like white on rice! ;-) The truth is that there is likely way more variation in energy return between rubber batches, and between segments within a single batch than there ever would be between 1/8" and 1/16" width of the same rubber. I've not seen any difference in winding, and the possible improvement in energy loss per strand might be largely theoretical.
David Ackery I use 1/8.
I find this is gives sufficient options for my needs. There may be slight variations in motor length but it is no sufficient to worry me, (or to require me to going to the extra trouble of dealing with 1/16 to get those small incremental steps).
For me making up rubber motors is a chore and while it is important it is just one small part of flying rubber models, and I don’t want to spend my life on it.
Rubber is fuel that we use, but there are many other aspects of contest flying that I need to work on and get right. The best rubber in the world will not save me if I pick bad air, the model is off trim, or if I mess up the launch.
I fly P30, Coupe, F1b and Open so I need cover all those options and find 1/8 does it for me, however if you are more specialized you may want to get more focused on the exact needs of that event. I do have some ¼ left, but that is reserved for that other rubber event,, catapult,, :-)
Tom Martin This page is a fantastic resource!!! - there is some 3/16" available through http://www.pelaero.com.au/ - TAN II SUPER SPORT Feb 2010 batch - don't know how much he has. $45AUD per pound.

Ross Jahnke I split the difference and bought five pounds each of 1/16" and 1/8". I will try some wake motors from 1/16" but think it will primarily be used in the coupes. I still have a good stock of 1/8 in the fridge, but its all tan II. Now you know how long its been since I was active.
Blake Jensen
Ross, I just read most of these comments and I think there may be a slight advantage for 1/16" although it can't be much.
One of the reasons I like it, which I don't think has been mentioned yet, is that it is the only size with a roughly
square cross section. All other sizes are are rectangular. Anyway, with the 1/16" it is very easy to tie a nice compact
perfect knot.
On Jon Davis....
I never met him and he probably didn't know me, but he did do something that no
one has even done to me before or after- He made me make a rubber band powered
airplane, the Maxine- I hated rounded tips and my Maxine had round tips. I hated
rubber bands for anything but holding wings and stabs in place but I had a model
in which its source of propulsion was rubber bands. I even flew it at the NATS,
probably 1973. I still have the wing- I think I made that thing with a rear fin
(any good model back then had a rear fin). So, my condolences to all that knew
him and wish I could have told him how he effected me, a lowly power
flier....God speed...

Kenny Oliver
Kenny was a study in contrasts. At times he was a wild guy out on the field, but he was also a very giving person. He showed times of greatness while flying and managed a trip to the World Champs with the US FAI team. I'm sure the folks flying at Lost Hills miss some of Kenny's antics out there. Also missed will be the model parts and pieces that he made over the years. Perhaps he will set up shop and continue supplying model stuff to all those who have passed the scene as well.
His last couple years were tough for both him and those close to him. The ravages of his Alzheimer's and heart problems sure could not have been fun for all concerned.
Marie and I were both close to both Kenny and Edith and their passing leaves an empty place inside.
RIP-Ken and Edith.

i have had requests from foreign flyers who are interested in renting Bikes for the Fab Feb week at Lost Hills. We will forward offers.
