![]() ![]() If I placed the tape over the SK-720 mounting crews, I ran into several issues (leveling, vibrations, etc.). However, a single layer did not work as well. I originally tried a single continuos layer of thin foam (several kinds and brands) between the SK-720 and the metal plate, but I found that this continuous layer transmitted too much vibration. The picture below is an original mounting method, which I tweaked a little bit before finding a better method. See below.īetween the SK-720 and the metal plate I just use 4 small squares of the 3M 4011 tape. I first stick a bigger piece of the 3M 4011 tape to the 3M 4408, and cut the excess 3M 4011 with a blade, so the 2 tapes are flush. I stick the 3M 4011 on both sides of the 3M 4408 to add stickiness to the 3M 4408. I cut the 3M 4408 into 4 squares of whatever the width of the 3M 4408. You can also find this cheaply at Home Depot, Ace, and Lowe's. I am using the readily available 3M 4011 mounting tape. However, the strap was introducing its own issues. However this tape is not very sticky, so I would not trust it to hold the SK-720 without a strap. ![]() There is only a single place that I have found that sells this tape in sensible quantities. I don't know about other parts of the world, but here in the state most places that sell this foam tape sell it in massive quantities, which can get expensive. I am using the 3M 4408 double sticky side foam tape. Interestingly, the mounting method that has worked best for me is actually cheap with readily available materials. Of course, it goes without mentioning that one must optimize the mechanical setup first, and make sure the motor is running true, before beginning the quest of chasing vibrations with the various mounting methods. Zeal tape, Align PU gel, Lynx anti-vibration tape, different and various double sided foams and tapes, etc. However, he mentioned that they would switch to 3M 4408 in the future because most customers live in warmer climates.īelow is a picture of some of the products and materials I have used. He mentioned that they included the grey foam in the kits instead of the better 3M 4408 foam because the 3M 4408 turns hard near or below freezing temperatures. He also suggested doubling the metal plate. He wrote that, during their testing, they achieved the best anti-vibrations results with either gel or black neoprene foam (3M 4408) under the plate and thin foam between the plate and the unit. My goal is to minimize the vibrations sensed by the SK-720, but still have the SK-720 mounted stiffly enough to follow the helicopters, and minimize the SK-720 wobbling on its mounting during sharp stick maneuvers. I even tried the Mr Mel method of tight wrapping with a zip tie over fuel tubing. ![]() Single layer, double layer, mixed layers. I have tried different and various kinds of tapes, foams, gels. ![]()
