Customer –
Simple and cheap metal geared servos for small applications. They do the job.

I bought these servos after having the normal plastic ones of which half (3 of 6) did not work well. It seemed that the failure could be due to faulty gears but after testing these with a “servo tester” I realize that it is the same as plastic gears and the failure must come from the electronic part since they have the same failure rate. You must buy twice as many as you need since the 50% is bad. At least I asked for a refund and Tech DIY Dynamic has complied, but it has cost me time and effort since I had to disassemble them from the model to change them.

Standard 9 gramme metal geared servos . I have used quite a few of these in virtually all my planes apart from my DLG. Where I need smaller servers. At this price you’re not going to get the best but these are good enough for most modellers. Ideal for putting in small models I have them in my Phoenix in my Fox and a few lidil gliders that I’ve made up. They usually take a Pounding or two before the start Twitching Rather than stripping the gears at which point Change them.
