Sawed the top of the frame to allow better access to the batteries. Decided to removed the end of the battery box and put a stop glued to the frame with an added support bock with some foam as a buffer. Did insert the foam and glue it to the wooden base. After some thought of the batteries getting hot they might melt some foam. So it was all removed and cleaned with a chisel. With the buffer at the bottom and some foam packed at the top of the battery It does allow removal / inserting of the batteries

Firstly removed the red wire on the esc wiring which makes it become the slave. Got all the running gear installed and the throttle stick travel set on the Tx/ Mtronices Viper 15 . Just these speed controllers are making a screaming noise when operating. any ideas what the problem could be ? Everything else is is running fine.

here is a link i was looking at https://www.modelboatmayhem.co.uk/forum/index.php?topic=3617.0

Any member know if Dave at Electronize is still available on the phone.

Have since discovered Electronize are closed for business totally.

Pic 1 my two Mtroniks Viper esc they squeal / singed when operated. So its a bin job.
Pic 2 As the motors were a wee bit loud and the vibration from them echoed thru 6mm wooden platform. The hole lot was removed carefully and no damage to the hull.
Rework I like it .

Well I sussed it out, the motor were screaming because they were lashed down too tight to the wood. Must have taken more that usual power from the Mtroniks esc to have the motors run. Also the platform they were strapped to enhanced the scream. Both on the bench working now Also while passing the time I strengthen the below motor area and 2 section aft with fibreglass tissue. Looking into the possibility of changing the drive system to pulleys and rubber band system. Working out the belt diameter, done this with the Meteor and it worked. Many thanks to members for their help and assistance.

Had a choice of chain drive, 1to 1 gearbox drive, cog drive. and belt drive. Opted for belt drive ( not the teeth drive) Made a pair of engine mounts out of scrap ply. Mounted them on 12 mm ply to get the right tightness between the two pulleys. Using a 20mm diameter x 2.5 thick set of belts belts from Thernobotsonline.com Got the pulleys from Mobile Marine but their belts were too thick and long. Used their pulleys. Pic 2 is where I'll put holes in for motor to take air in. Pic 4 the three screws is to be able to remove motor/ mount quickly.
