Thank you all, The boat did not sail today due to an unrelated problem. Plan is to fit the new ESC's which arrived today and make sure they are correctly programmed, also considering losing the mixer as it did not alleviate the problem. It will sail next Wednesday and I will give you an update! Thanks again for all your help.
Hi Berty, That is what I will be doing at the lake tomorrow. I have found the problem impossible! So in the absence of anything else will try a new esc! How can something change when it is in the water! There are no connections to the shafts or external in the water! Anyway it will be sailing backwards at Bury tomorrow.
The mixer was used because the problem was present with a Y cable splitter. The mixer is Mtroniks WTail mixer and is connected to the rudder. Everything is fine on the bench even full both ways. It is powered by a fully charged 11.1v Lipo
Hi Dave, I have used two radio systems Planet and Spektrum to see if that was the problem. The problem is the same with both. If you use either ESC and motor there is no problems. The esc were connected direct to the rx and are now connected via a mixer unit. I can not understand how it is fine on the bench but not in the water. I have tried lifting the transmitter to see if is about the height and walking away to see if it distance. Back to the water tomorrow with new ESC's. John.
Twin 550 brushed motor Pt 109. Motors run fine on the bench (forward and reverse). When in the water the boat goes only in reverse despite the direction of the stick. Have tried another radio and have the same problem. The motors have independent viper ESC’s. Originally it used a cable splitter and then used a mixer and the problem remains any ideas?
Hi Allen, I have a Zippkit Springer as you can see from my picture. It was simple to make and works well. Only suggestion I have is get the single motor version. My friend bought the twin motor version at the same time and it is overpowered. John.
