Hola Jose, welcome, Bill Hannan design and good flyer are pretty much synonymous.   Wink

It looks like the prop will need to turn clockwise, did you set it up like that on purpose? Is that to change the torque roll?

Not the propeller will turn normal the picture makes it look weird. I tell you that I participated in the forum for years with Jose's wig but I lost the password and I signed up as José 1. If I recover the old Jose I will return to him

I ask you about the most advisable measure -1/16 or 3 / 32- for the rubber of my models peanuts, also comments on the length of the skein would appreciate all this data. Regards

One loop of 3/32 should fly your Peanut.  Length about 2X distance from prop hook to rear peg.

3/32 would be the best option but what would happen if 1/16 would be used as would the duration time. I have no knowledge about rubber better and I would like to know since here in Argentina there are no articles that explain on the subject. Thanks Jose

1/16 would be unable to properly fly the airplane unless the weight less rubber were around 6 - 8 grams. 

1/16 would need to be doubled, two loops.  It then would be excessively powerful and make the model difficult to trim for flight.

Stay with 3/32 for now.  It will be plenty of power but not too much.

Thanks for your comments, I will do what you advise me. I tell you that now I have stopped the construction of Bede 4 because I have to wait for an order to arrive to Peck Polimers of Esaki and rubber. In Argentina you do not get any of that and the customs hopefully let you pass the order; a recent fact to Volare was returned. Soon I will compare George de Volare again and hope to be lucky. Those are the difficulties of those who make peanuts in these places. You will see that Bede 4 is on a "wing" of a Piper 1/4 scale that I am setting, I already have the fuselage and the group of tail finishing, when I fly I tell them, it is not mine to do for a Friend: Pablo Lowisky . Greetings José

That is an absolutely beautiful pitch gauge pictured in your first posting!  Can you tell us more about it?

Thanks,
Scott

Jose, as a very rough rule the thicker the rubber the stronger it will be.  On the other hand the longer the loop of rubber is the weaker it will be.  These rules can make matching length to thickness.  In one of the other answers 3/32 rubber 2X the distance between the prop and the hook was suggested.  You came back with can I use 1/16th rubber the answer was not to try it.  I would suggest that 1/16 can be used by shortening the loop, how much will have to be experimented with to find out but I would try something like 1 and 1/4 the distance between prop and hook.  There are limits to both of these extremes but that is what makes playing with this stuff so much fun!
