Hi all here the way i bend wood . first i draw and layout the line on paper the i put finish nail in 1/2 ply on the outside of line then i take a pvc pipe and cap one end then i put the wood into it then i use a 1300 watt monster steamer to steam the wood for 5Min then take it out and put it into the building jig and let dry over night or you can bend it on the boat and clamp it down it bean very easy .hope this help anyone ,here some picture of it

The openings in the stringers where the motors would be installed through has been designed to allow for a 540 size motor with a cooling jacket. Before assembly make sure the motor screw holes is big enough and that the rear three bulkheads have been strengthened/reinforced. To tighten them, some kind of angled driver would help. I agree it is tight (I struggled my ass off to tighten the stingers screws on the inside , but did get it done eventually) but with the right tools it can be done. Some guys let their hatch stretch over the sponsons to work on the motor from above, I didn't for aesthetic reasons, and I know I am going to struggle a bit, but mine won't be for everyday running. It would be more of a working testament to my building abilities... I am still assembling hardware, haven't got the dough for electrics yet.

ok thanks lomdel! im going to get this build going soon!! and im quite excited! have you looked at hobby city electronics? you can get an xl size motor for 30$! and a 100 amp esc for 30 also! this is where im going to get my electronics hopefully

Two 540 XL's would be overkill for this hull IMO. I intend to run 2 540 9L's with 2 120A ESC's.

frp look on cat

hi lomdel kennyrach/normam, all this is some pics on the build it's lots of time but worth it hope you guys are doing some videos, to show set up and speeds. hope to see some soon.rreyes

[kennyrach]

wow m8 looking good and fiberglass side and bottom .Are the side made from sheet that you made yourself or got off the web

[rawsonreyes]

hi kennyrach, i did the frp skins for the hull the only wood parts is the cutouts.thinking of removable hatch covers for the motor sections just like fullsize hulls lots of work but very rewarding when finish. thanks for the support rreyer.

Why did you use chopped mat instead of woven fabric? Mat isn't NEARLY as strong.
