Servo Tape
By James Goss
I have used servo tape many times over the years, but here lately I have really been using a lot of it. With my new Postage Stamp design I do not use servo wells anymore, instead I use servo tape and one nylon tie to secure the servo, battery, and receiver to the coroplast. This method is much faster than cutting servo holes and using wood rails to secure the servos. The servos are mounted on their sides to give more area for the tape to hold. I have never had a servo to come loose from the tape, as a matter of fact I have to use a putty knife and pry the servos away from the plastic when it is time to change the radio gear. If it is installed correct the servo tape will hold as well as any method I know of for securing a servo.
Here lately I have been experimenting with many different design Stamps and have found it necessary to change my radio gear in some cases two or three times a week. It is quite annoying to remove the servo tape from the servo because it will not turn loose clean; it leaves a residue that is very time consuming to remove. The only way I know to clean the servo tape from the servo is to scrape it and then use acetone and elbow grease, takes about ten minutes to clean each servo. This can add up into a lot of valuable shop time wasted if you do several radio changes each week. Also let me say that you must be careful with the amount of acetone you use on the radio gear. Do not soak the servo with acetone, instead use a tiny amount on a shop rag and rub the servo with a circle action until the residue becomes soft. You do not want to get any acetone inside the case of the servos.
I knew there had to be a better way to remove servo tape from the servos than the method I was using, and here is what I have come up with. This is the best way I have found to install servo tape to plastic or wood. First be sure to have a servo tape that will cover the entire area of the servo, usually a 1-1/2 inch tape will do this. Clean the servo with alcohol at least three times to remove any oils. Do the same for the plastic area that will accept the servo.
Here is what makes the difference and allows you to remove the servo tape from the servo in about ten seconds.
After you have cleaned the servo with alcohol and before you put the servo tape on the servo, wrap the servo with black electrical tape, about two good layers will be fine. I use Scotch 33 + because it bonds even in cold weather. It cost a little more, but it is worth it in the long run. After you have wrapped the servo with the electrical tape you must clean the tape with alcohol to remove any body grease you got on it while wrapping. Now peal the backing from one side of the servo tape and bond it to the servo. The servo is now ready to install and I assure you that the servo tape will bond to the electrical tape just as well as it will bond to the servo. When you get ready to remove the servo simply pry it off with a putty knife and cut the electrical tape to peal it off, takes about ten seconds. I have found this method to work well and will never use servo tape again without first placing electrical tape on the servo. I would not recommend using electrical tape unless you are mounting the servo on its side because placing electrical tape only on the bottom of the servo without wrapping it around the servo might not hold well enough.
