Quite correct Martin, - good memory😁- left to counter the motor torque and down to prevent nosing up. Some planes don't need much of either (high wings often need quite a bit,. This is sort of similar as too much up thrust causes the bow to go down (hence the nose diving in the earlier vids caused by the thrust being parallel )- now has about 2Deg down, (pushing the back down).

Hi Jb,
Many years ago i messed about with rc planes and i have a vague recollections of having to angle the motor and propeller of centre and to the left to aid straight flight. I may be wrong you know what my memory is like. Martin555. 👍 Like

Thanks Martin that's pretty clever , wonder what the linkages look like and how many servos it's using (possibly 1 with a sliding 2nd?) Probably would work on the airboat but would need more curve frontwards so you get a good reverse thrust. (is that like the kitchen rudder setup? - separate vid) You can actually buy reversing props for R/C aircraft and they are quite impressive. https://www.youtube.com/watch?v=PoNgThzzERI
A couple of vids here might interest you, the Raven also has thrust vectoring (can actually shift the motor thrust line up down sideways. Amazing the stuff you can buy these days (if you have the money) I actually thought about a smaller version, but the expense killed that idea, (easier just to spin an airboat to stop quickly😁) JB 👍 Like

I'll be out the next fine period Graham to try and set the steering. It seems to have a few different modes depending on power applied (ie full power sort of torque slides to the left but low speed wants to go right). Needs a bit of experimenting. I put a 9x4.5" prop on it to take a bit of load off from the previous 10x5" which seemed a bit much (motor's a revver not a torquer). Battery was still at 3.8v/cell after about 8 mins of mucking about which is not too bad considering this motor's a power hog. I think either the 35/48 1100kv or the 35/48 900kv I have might be a better option and give a better quieter run time.
I find with the scale models, I tend to build them, use them a few times then leave them on the shelf, - this I can chuck in the car and run anywhere. can't wait for a nice sunny calm day and a full tide down at the estuary,😁 I can go for miles down there!. Might attach some spray deflectors for the salt water though (even though it stays surprisingly dry on top. Have to attach GPS and camera next run. Twin rudders were much better, very responsive, (learning to be gentle) can always put in dual rates ( probably only need 20% at full power) doesn't take much to get it sliding😁! JB 👍 Like

Certainly was a lot better on the water Martin, as I thought it should have been. Couldn't really see where I was going which limited things a bit, but heaps of fun. Might be taking the other models down there and making the most of it before the fun police come. Only problem is those flood control ponds can be quite deep, (maybe 12ft in the middle so you have to be careful. Very sticky deep clay mud on the bottoms as well (almost lost my flip flop getting the boat out of the rushes. Eventually the rushes and Carex will overtake the edges making it difficult to get near the water (unless I do a bit of secret cultivation to maintain a 'shipping lane'😉) Might need to take a kayak for emergency retrievals😀

Thanks Martin, yeah, airboats obviously not really primarily designed for high speed on land so can't be expected to handle perfectly. There are vids of Guys coming out of the water and travelling 60m or so to park them, but all at slow speed. You might like the vid (first half)

Thanks Graham, I think it was just the whack it got jumping onto the footpath, normally it's a tight clip on fit. Seems to want to turn right so I think some right thrust might be required. Apart from that it seems reasonable. Just a bit of tuning to do.3s 4000mAh battery didn't last that long (about 3mins) as it's having to constantly push hard on the grass. I can always go to a 1000kv motor and more pitch (this is 1450kv, more for ducted fans and just a trial, can be run on a 6s with a 90mm ducted fan at around 34000 rpm) and get the same thrust with less noise (just not as fast) Nowhere near top speed at the moment.

Might just pop into the haberdashers and buy a nice bit of frilly lace to use Martin, YEAH RIGHT😂 The big Spotlight store here has truckloads of stuff like that, - might have a gander sometime. Lace painting takes a ton of clearcoat to make it look good as you need the depth.

Re - You sneaked that strobe light in Jb.
Suddenly remembered I had them Martin,- bought about 4 from a Chinese $2 shop a few years back. Have actually taken the tiny board out (6 LEDs) and wired them to run on a 3v button cell in my 2 ducted fan electric Vampires. You can see them from about 100m away on a dull day. Have one of those battery voltage monitors with a bright blue LED and a Piezo horn fitted to the 'floor' of my re-created Graupner Terry plane, and just need to fly overhead at about 50ft, and if the light's not flashing, you are still ok to fly,-quite handy. This type could be fitted to a boat as well as you would only need a small hole to see the LED. JB 👍 Like

Thanks guys, shouldn't be too long Martin, some nice calm days at the moment, but starting to get cold now, (Autumn) Taken a while as I have had other jobs to do but getting there! Should be something that can be chucked in the car used anywhere, and I won't have to worry about knocking bits off. Will probably use it more than the scale boats, and as I mentioned I might try strapping a camera to it for a bit more fun. Should be an ideal platform for filming other models from (if I can ever find anyone even running boats these days). Can always use it for trolling, taking a fishing line out, or a rescue boat, (no prop to get caught on weed😁)
