Hi shipmates, I have nearly completed building Atlantic Challenger, i am having a problem with the motors. I am using a F14 navy transmitter by Robbe, i am using the left hand stick only to control the two motors, i have linked the 2 speed controllers together with a y lead. the problem i have is that both motors do not start together at first push of the lever, will this cause me problems steering the boat at slow speeds?. Any help would be welcome, Dave.

Dave. i have several boats with only one ESC and two motors, and none of them start up both together at very low speeds. You will always get some variation in motor, friction of couplings, prop shaft and so on to affect initial start. Unless the motors are still not together at slow speed, rather than just VERY slow speed, this should not be any problem. I presume you have no tweaks available on the speed controllers? Also , is this in the air , or boat in the water. If in the air, I would not worry and plonk it in the oggy first to see what happens then.

If I try very hard, I can get the 4 air props of my Sunderland to start one at a time, always impresses!

In any case, would you want to go that slow on such a magnificent fast boat ??

Hi Ashley, Thanks very much for reply on what i thought was a problem.

What i should have done was what you suggested, plonk it in the c02 and see what happens.

I will be doing that in the near future, will let you know the outcome.

Many thanks, Dave

Make your own contribution to the Website

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
