Hello to all you FF Rubber Powered Nuts out there... that's me and who else?
I was thinking this morning(this can be a bad thing... only 1st cup of coffee). I noticed the torque meter on my winder has a chart for 'Breaking Torque for 1/8" Rubber'. I have been using 3/16" in my models, but I am planning on going to 1/8" and I can increase the strands to get the same amount of rubber.
The benefit to this is that I will be able to get more winds with the same weight of rubber. I have noticed in other kits (non Guillow's) the rubber is 1/8. I have not been using this as I thought is was too small.
For my flight of my 100 series SE5, I used 1/8 as the model is very small (18 inch ws) I only had 500 winds on the motor which was 1.2 inch ounces of torque. I see the breaking point for that rubber is about 6 in oz. Next time I will wind to 3, then 4 in oz. She had a 7 inch Peck prop.
For my 200 series DH4 I plan to use 6 strands of 1/8" rubber. She will have an 8 inch Peck prop.
I plan to start using 1/8 rubber on most of my models and use the 3/16 for the models that have a ws over 30 inches. (1000 and 2000 series)
It seems to me the biggest factor in getting these models to fly is understanding our power supply and proper propeller!
so... any questions, comments, or thoughts are welcome... now for that 2nd cup of coffee!
