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

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 .

Thanks John I am open to the upside down motor idea. Meanwhile looking at alternative motors and size. Also I applied fibreglass to the hull around the prop ends and the further two compartment aft. Scrapping the belt system will try and have a direct coupling setup if possible. Took ages to line up the belts.
Hi ToraDog Went on to the site you gave a link to and signed up. I'll look thru and see what is what. It'll depend on what motors I get and will put the Graupner motors to the back of the cupboard. Thanks again
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.

Couple of pics of home made motor mounts that would be suitable for your model. Also, your motors may be a little too large for that model. I myself would go for MFA Low Drain 550s.
Hi John I'll switch to MFA Low drain 550s. See you have supports running parallel to support the mounts. Will copy that idea looks sound. Something in the back of my mind said to resin / fibreglass the inside of the hull. It may need it in future Will make them out of ply as it will make a strong mountings. Many thanks again 👍
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.

hi Martin, if you removed those thick lumps of plywood from underneath the motor mounts - shaved a bit off the bottom of the motor mounts - so they fit snuggly into the bottom of the hull - using this method would this not allow you to fit the motors directly in line with the shafts and dispensing with the belt drive.
