Dave, when you enlarged your plans for the 43 inch gasser you built did you stick true to the plans the bottom of them sponson's are really different than I've ever seen.
I was always used to seeing the cutaways or the air dams in the middle and never on the outside let me know if you went this route staying true to the plans with the bottom of the sponsors.
I am not only using these plans for 10 scale electric but I am building sport 40 nitro with the same plans I expand them in respect to the size as they need to be.
Jim
yes I built center tub and sponsons almost same as shown on plans
I added layer of 1/32 ply on top of the 1/16 ply to build up height
of the recovery pads the front ends of the sponsons
my boat has 1/8 ply frames with 1/16 ply skins
yes too much wood too much epoxy
it's heavy but very stable with zen 260 power and PT sport cowl
I put a nose on the bow block to locate the cowl further forward for
the gas engine. I am sure this helps to prevent blow overs
compared to the dave frank semi-scale design
compare the center line engine well with offset wells in 138-8255 scales
yes the tunnel air relief sponson notches and ride pad angles are different left and right my 43 inch gasser ran good with a stock zen 260
a gas sport play boat
I used an extended flat bottom strut and 4 inch rudder bracket
to make the boat longer a typical gas sport set up when i
built my boat in 2004
I suggest building your boat as shown on plans possibly eliminating
the tunnel floor break angle similar to the flat floor ML sport designs
I don't remember if the plans show a tunnel break or not. see above
compare details with newton 138-8255 plans based scales
dave frank designed a great looking good running boat
