Tfl arrow rigger build and setup

[kfxguy]

Well sort of. My first time fooling with a rigger. I know this thing has been out for a couple years now but I never see anything on it. My impressions are it looks cool and is built pretty decent for an rtr. Pretty much genesis style with wood and stuff. The wiring and water hoses were a little bit of a mess. I couldn't get a battery in it. So I put it for sale last night. Then today I decided I'm not going to give up on it that easy. Figure id rearrange things and clean it up, "Travis" style haha. Anyway, servo didn't line up., with what I had anyways. Ugh. Ripped the mount out because I'm not a fan of a zip tie to hold a servo in. Then I opened up the opening a little in a couple areas so I can get a battery in and the servo. Bench tested it and after a couple throttle blips the motor mount detached. Lol Guess it wasn't glued in well. Lol. No problem. I expect these sort of things in an rtr anyway. I didn't like the slack that a "z" bend in the steering rod gives so I made my own steering rod with a ball end. The rudder had more slack than anything I've seen before. I have some titanium rod just the rod size. Cut a piece and slack gone. Also the hatch had no floatation so I glued a piece of foam to it.


I'd like to add to this. The little issues I had are far outweighed by the performance of this little screamer. This thing hauls butt in stock trim. Stock prop and everything, it's downright impressive.

New one. Well modified what I had.

Motor mount detached



Glued it back in with jb quick but forgot a pic of it. Here's the completed layout.






And with battery. Yes that's a 3s 5500mah lmao

I also would like any pointers with tuning this thing. I've got the mechanical part taken care of now. I feel the boat is solid and put together well. No slack in rudder or linkage. I hope to get some decent speed out of it. This came with a x435 prop which I just finished s/b. I plan on ordering a abc 38mm for it. I'm not sure if I should start on 2s or 3s.

What do you have? Two turn fins? If I even try a left over she goes. But... Whatcha think?

[kfxguy]

I only have one turn fun. Does decent left but not as good as to the right. I will probably put another one on it as I don't race. I'm pretty impressed with is especially since it's stock and on 3s with a horrible stock prop.

Holy crap, that thing is crazy already! What are the plans for it?

My turn fin is quite broad so that is likely why it trips. I assume yours is not so long, if you put another one on make sure it is the same. I wonder if one off one side of the body instead of out on the sponson would make it more versatile

I ordered an abc prop for it. The stock prop looks like a brass toy prop. I also ordered the correct batteries for it. I was running a 405gram 5500 3s 70c revo in it lol. The batteries I ordered weigh about half that. I'm putting a small rudder on the top of the rudder too. We were running in rough water and my some managed to flip it. The prop was actually in the water when it was upside down but I couldn't steer it. Put a little fun on the rudder and I'll be able to drive it back to me upside down. Lol

I'm going to order longer boom rods to widen it by an inch or two.

[srislash]

I like that idea. The rudder that is.

Just saw your belly up rudder on YouTube. That is pretty neat!!!

Haha thanks! It should work like a champ. Here's the video

It was designed around a 280g battery, so you're only 45% overweight not double at 405g
