Anyone get super short run times on their stock rtr Nimh? It seems I'm getting about 5 minutes of run time or less on the stock 2400mah nimh. I've fast charged it with a 50w prophet mini multi twice. At first it would cut studder a little. Made me think I did something odd to my transmitter settings or some random interference from something. I'm charging a 5000mah 2s lipo now to see if it does anything differently on 2s.
