Thanks guys, this is exactly the type of first hand info and advice I was looking for! RCTech looks like it will be a great help in getting back into the Hobby

Much appreciated.
@Valk/Azeroth Thats comforting to know in nitro it will be a simple deal. My older batteries probably aren't 1600mah (atleast not anymore anyway lol!) but I will see how it goes. Wouldn't mind upgrading all packs to LiPo or LiFe or whatever is the most readily available and reliable these days.
Addict those are good pros and cons. That squid review prob was the first thing I saw about the brand, I find it wierd with Savox featuring ads on so many websites I go to that they haven't sent more servos out for reviews.
Drake, it just goes to show that in this day and age of RC that companies can make proper stuff that works like your Flysky. They don't cost a fortune but people are happy with them, I can never get it how other companies with more $ and clout continuously put out products that "also need xx". Quite annoying in this hobby.
Now this still leave me desperate for info on the 1231 and other of the "Extra Tall" 45mm servo. Really need to find fitment on those, please if anybody uses them speak up.
I have that "itch" again so I think I may end up with a few new servos in the next 24hours if I find and answer lol!!!
Thanks so much so far and keep the experience coming!
