Ive had issues with spektrum, and know alot of others have. Glitchy and cheap feeling. I went to futaba 4pksr after owning a dx4s and have not regretted it at all and have not had a single issue, nor heard or seen the issues youre talking about, and the people i know, majority run futaba, with some sanwa and very few spektrum. Each to their own on look, the futaba isnt the prettiest radio, but it feels good in hand and trumps the spektrum gear.

The more torque the better, less strain on the servo. 7.4v will be optimal, and wont tax the system as much as you think. Ive always run my servos on 7.4v and never had an issue.

Hard solder is best. Like i said, less resistance and less chance of a connector failing. It may be a bit more of a pain to remove, but atleast youre less likely to have a plug unsolder during a race or come undone.

I would stick to 2 rigs tbh. Best way to go about it. Throw a 1700kv into the Axial, doesnt even need to be Tekin, so you can keep the costs down as its only a basher rig.
Ya the plugs I am looking at are overkill, but overkill on connectors, being that they are that restrictive, heat building area, is never a bad thing. If I used the same series for motor connectors, they are so huge and powerful that honestly the resistance increase would either be none because they are rated higher than 10AWG wire itself, or so little that its unnoticeable.

If I can figure out a way to easily clean the system with the motor just soldered straight on, then I will do that. Its really cool that your EC5's havent given you any issues, that shows that they are good connectors and and probably slightly under-rated, but I would still recommend that you swap out in 1/8th scale applications. Same thing if you are running any 12AWG wire, as its rated at 50-60 constant and 100-110 burst as well. XT90 (90constant rated)s wouldnt be a bad choice for ya, they are pretty popular and easy to use.

The best way to keep resistance, heat, and issues to a minimum is to always go overkill on wiring and connectors.

I have read up on Spektrum issues since my last reply. I cant believe how many people have issues with them. How are they still in business when their prices are so close to the opposition? Guess I got lucky... Yea I might have just decided to go all-out and get the M12S-RS. Probably the last TX I will EVER need lol.

I will try both 6.0V and 7.4V on the servo. If 6 isnt perfection then I will turn it up.
