Alrighty update time!
since last update i have completed the beast and ordered another prop (16x8 apc)and a Turnigy micro tacho.
Did some testing with the tacho before any runs.
With the 15x6 APC, i get a max of 8670rpm and with the 16x8 APC, i get a max of 7080rpm.
Not too bad guess considering i haven't gutted the muffler box and still have the stock carb on it.
I then gutted the muffler box and drilled 2 10mm holes, and the results were quite satisfying!
Now its spinning the 16x8 APC at 8190rpm, a gain of 1110rpm!
I even swapped over to the 15x6 and got 9450rpm, a gain of 780rpm.
All was great until i heard a strange rattle, i killed the motor to find the motor mount had a crack in it
so i made up a new engine mount out of 6mm aluminium that i found at the boatbuilders scrap bin that already had the 90 deg bend i wanted.
i used angle brackets to attach the mount to the uprights this time as ozpulse pointed out that with my old one, the adjacent 90 deg bends would have stressed/weakened the ally hence why it cracked.
heres engine mount V2!
This sod wont break! so i thought... instead of the ally breaking, the black pieces of angle cracked right up the slots!! At least i got a few runs and vids before they let go!
first run was next door at the park, was fun avoiding all the obstacles!
1st run, hidden tree cam
2nd run pt1
2nd run pt2
2nd run pt3
2nd run pt4
and here is its first water run! she turned out to be quite a handful to control but fun nonetheless

i did actually chuck my gps in it and did a bit of a speed run (still to scared to give it WOT on water yet

)
anyways at about 3/4 throttle i got a top speed of 31Km/h.
1st Water run pt1
1st Water run pt2
I was having great fun spinnin about on the water, then i decided to venture out a little further to try get some high speed stuff.... dang thing went and sucked in a little water and stalled, right in the middle of the river. all i could do was just just back and let it slowly drift back into shore some half hour later

in the mean time i chucked my mono in the water for a run after i swapped over to that old tuned pipe, got a new top speed of 36km/h!
