I’ve had a GT5 and a Radiolink, I’ve just got a Dumbo RC DDF350 and I would pick it over both of them, I paid about £50 off Aliexpress and turned up in about 5 days
Up to 10 channels (rx dependant) I’ve got the 6 channel version, but the extra channel are now light controllers, has some really nice settings like cruise control, winch controller etc
