I know its a nice dillema but which engine should i get for my Edge 540. Options are as follows:

ZDZ 60
ZG 62
DA 50
3W 50 QS

Im torn between them all. Im more biased towards the DA 50 or 3W 50 as they look soooo nice and have heard great things bout them. Any opinions would be appriciated.

Also what electrical setup? I was thinking of two 1800 mah both feeding reciever and servos with a SMC battery backer so if one fails or there is a problem one can feed both systems.
Was looking to get those Fromeco switches where you have to push a wire in to break the curcuit but cant find anyone in uk who supplies.

8411's throughout except throttle and choke.

Whats everyone else using.

Many thanks Matt
