250 forum posts 44 photos | I am currently scratch building a catamaran workboat in 1:16 scale, based on the drawings for a James Pottinger design called Searcher. The vessel has twin 540/1 motors, 35mm props and twin rudders. I will be using two 6V batteries connected in parallel. I will control the two rudders via `Y’ lead. Please could someone advise the best way to control the two motors i.e. one ESC or two. I normally now use Action products. Many thanks. |

250 forum posts 44 photos | Dave - Many thanks for you prompt response. I had purposely made the void below the deck between the two hulls a bit deeper to allow for the depth of the enclosure used for the majority of the Action units but unfortunately the P94 has the two heat sinks. As I cannot use an alternative location it will be neat hole in the deck to allow the heat sink to protrude and then a suitable cover such as a dummy crate. That is why I enjoy scratch building....problem solving. All the best - Keep safe |

250 forum posts 44 photos | Yes, thanks for that I will give it a try. I think the total void depth is 32 mm and I always have a good stock of extruded ali angle as I often use it as an assembly aid or for such things as making my own motor mounts. |

250 forum posts 44 photos | Dave - I have made a a pair of "gull wings" from extruded aluminium as advised. On dismantling the unit, there were no Heat Transfer Pads i.a.w the Assy Drg but there was a small quantity of white paste at each interface point which I assume is now used in lieu of the HTPs. Is there a household equivalent to this paste or is it a question of scrounging some from Kyje at CS. Many thanks. |

![]() 4025 forum posts 282 photos | David It's heat-transfer compound and as far as I know has no domestic equivalent. At that voltage however you should have no need for it. The cost of the transfer pads went from around 2p each to over 20p in one jump, at which point we decided to ditch them and go with the gunk. I very much doubt whether Kyje will have any.

250 forum posts 44 photos | Dave - Many thanks for that. I carefully preserved the paste on the removed units so will add that on reassembly. |

250 forum posts 44 photos | Dave - I am trying to incorporate a Micro Diesel Sound Simulator (P63) with the P94 previously mentioned in the earlier posts. Am I correct in saying that I connect the ESC terminal on the P63 to the terminal marked H2 on the P94 and therefore require a lead with a male connection on each end? This item being available from Component Shop. Many Thanks - David Marks |

![]() 4025 forum posts 282 photos | David You can connect the P63 plug (which would normally go into the receiver) to the pins H2 on P94, so you won't need a special lead. It won't be vey loud. Dave M |
