[QUOTE="mimixtz, post: 35770, member: 7144"] Those who wants to be 100% "by the book", living in EU and using Android device have problems without OTG. Why? Most Androids are doomed to only 2.4WiFi frequency. So this is used for RC-Android connection. Which means that RC- Spark connection can only be 5.8GHz. Both, 2.4 and 5.8GHz transmitter frequencies are significantly reduced because of (stupid) EU regulations. 5.8 even more than 2.4. Besides that, there is a "rule": higher frequency = more poor range at the same transmitting power. Bottom line: Spark lost its signal at 200m. With OTG connection between RC and Android you can select 2.4GHz frequency between RC and Spark. Range was 300-500m in that case. Luckily there are other "not by the book" options.;):) [/QUOTE]
