What kind of adhesive are you using to secure the G10 sheeting? Very inventive use of unique materials! OUTSTANDING!

[K.R.Joye]

Thanks guys its been a fun winter project. Can't wait to throw it in some water!

For bonding G10 (compression molded epoxy sheet) this stuff works the best. Takes a little while to get used to smell. http://www.amazon.com/gp/product/B00...QTWAXD9HDTK1S8

Great first run with the `NEW' ARC 36-75-1 hit 50mph(GPS) on 6S 40C Turnigy cells, Huaya BX200 ESC. Had to take it easy windy day, 3-4" chop! Should work fine for our club racing class. Brought in after 6 laps motor temp only 110F w/cooling jacket. That little motor puts out some impressive power!

Hi Ken

Nice build, I really like the inboard strut mount and the "wet well"

are you keen to tell us what motor are you running ?

So is this hull about the same size and weight as a Whip40?

[K.R.Joye]

I think the Whip 40 is 37" this one is 35". Long story short i needed to keep the overall length to 35"(min for SP40 IMPBA NAMBA) in order to keep the after plane below 60% per NAMBA sprort hydro rules. The sponsons are little longer on the Whip 40. My hull weighs close to 11 lbs RTR, i added some wedge(more AOA)to the sponson ride pads so the boat runs very light.

I'm using `NEW' ARC 36-75-1 EDF motor exclusively designed & sold by LIGHTFLIGHT Big Power/Small package. The motor design uses C-Clips at each bearing shaft end & heavy duty bearings, can handle up to 8S/150 amps. Currently playing with various pitch props in the 45mm range, when i find the right prop i'll get some vid.

Is that about the same weight as the Whip?
The motor sounds decent!
