Well finally getting there
Topdeck is now moulded just needs trimming and will add some wood to back it up ,just gotta leave it now for a week or so to fully cure before splitting and prep the bottom for moulding

Made 1st hatch for this build,only thin layup to break in the mould but also 1st time test fit and check clearances round the engine ,fits nice and clearance is not an an issue so pretty happy

Also now moulded the bottom of this build,fingers crossed releases ok in a week or so ,then wont be long before laying up and pulling the 1st hull

Just placed engine and exhaust in hull while still in moulds so while letting it cure I can make a start on the stringers and transom plate and check clearances

Modified the exhaust to get a better tune length

F1 madness · « **Reply #42 on:** April 07, 2014, 09:44:25 pm »

Neither can i bud ,will be a steady run start with while breaking in engine and start setting it up

derekwarner · « **Reply #43 on:** April 07, 2014, 10:16:51 pm »

F1...the outer edge/length/diameter of the exhaust tune pipe would appear to be in close proximity to the hull side wall

We see a small amount of 'fire sleeve' on the exhaust manifold [is it only protecting the water cooling tubing?]....but will the hull get any additional heat protection?..............Derek

F1 madness · « **Reply #44 on:** April 07, 2014, 10:21:58 pm »

Hi derek
Theres plenty of room round it bud theres about 2.5" between the exhaust and side of the hull aswell ,just pics dont show it clearly

F1 madness · « **Reply #45 on:** April 08, 2014, 05:01:58 pm »

Started the engine for 1st time ,2nd pull it fired straight up so well pleased ,no major issues

Also decided to make slight mod and allow more exhaust heat out
