little confused here. Love my viper but considering replacing fan and motor due to maintenance, few hundred flights plus now on her. Whats another 6s option thats a slight upgrade in terms of noise and speed for this plane. really appreciate any help

You won’t actually be able to get a better sound as the stock set up is very good. You may be able to get a marginal power increase with a JF 90mm on 6s but I went for the fms 1500kv unit. Drops right in and fly it on 9S. Unlimited vertical and sounds brilliant. Best sounding edf I own. Worth a look. 👍
