Avanti by boaty Captain   Posted: 5 days ago
[Score: 9/10] 29"/1200g Avanti Capable of 15mph and a runtime of 5mins Single Propellor (2 Blade X Type 35mm) Direct Drive to a OBL29/19-15M (2 Blade X Type) Powered by LiPoly (11.1v) 15Amp/h Batteries Controlled Through BLC-40M (25Amps) ESC - Comments: ARTR fast electric by Thunder Tiger. Deep vee powered by Ripper Brushless outrunner. Will reach 30mph+ when flat out. I replaced the radio that came with the boat with stick operated Futaba T2HR as I preferred "stick" to wheel for sailing fast boats. Initial problem was slight leak where stern tube passes through the transom but soon fixed it with epoxy. Electrics are in a box at the stern which is appears to be water resistant. Though not for a raw beginner, it is great for a second boat especially if someone is hoping to move on to a 6S . If not , it makes a good all rounder and is ideal for club fast electric racing and it performs well when doing tight turns. Boaty

Component Shop Do Servo Testers For Wiring I found this hope it helps

BTW John; Re LED testing: Yes I also use the 'diode' function of my multimeter to do a quick 'will it? won't it?' check. BUT that only tells me it works. With the tester I can determine the optimum current the LED needs, and thus the dropping resistor for any given supply voltage. Above a certain current, usually 20 to 30mA for the 3 and 5mm types, depending on type and colour, more current just produces heat instead of more brightness. Pic shows my tester, only few quid😊, see mA scale along the top! Runs off a 9V block. Cheers, Doug 😎

Mornin John Re detector circuit: It's not very complicated, only 3 or 4 actual components. The clues are good RF diode and a very sensitive meter! I just bought a couple of 300microamp full scale meters. Will do a little blog when I've tidied it up and boxed it. Re Heli: can you post or mail me pics of the TX, RX and ESC please. Brushed or Brushless motors? Given manufacturer / model numbers I might be able to figure out what the pissibolities are. No promises though 😉 Sounds to me like the TX stick is set up for forwards / backwards like a normal car or boat set up. I.e. for 0 to full speed in either direction is only half the stick travel. For aircraft 0 is full down, giving you the full stick travel for the speed range. The ESC probably needs to be 're-educated' and the TX throttle stick re-programmed, IF at all possible with the TX you got with the Heli. Re " P.S. Signals come from where Doug?" - Don't understand the question John ?? Cheers, Doug 😎

A question for you Doug A while back I got a little helicopter and Tx. 40 meg However I don't think the tx is the right one as it was one in a pile.. The problem is although it works up to a point the rotors don't move until the lever is about halfway through the range of movement and the rotors don't reach take off revs. The question is it possible to recalibrate or adjust the pot in some way to sort this? I couldn't test the set when bought as it was a place that sells S/H stuff from house clearances etc so no batteries etc So I took a chance as it was so cheap. I hope you can help as it's quite a cute little thing. Ciao John P.S. Signals come from where Doug?

Doug When you get the circuit sorted for the B/B tester I'd like a copy please. Will it be switchable wavelength wise. I/E one to the other? Re . testing LEDS I use my multimeter set to diode testing Eezy Peezy.🤓👍

been look for one of these for 40 megs for some time. been looking into the arduino route but only find it for 2.4 :(

Stand easy CPO 😁 Neat gadget👍 But I wanted a broadband device so I could also use it for some vintage 27 and 40MHz gear which I still use for my submarines, or just out of nostalgia. They still work so why chuck 'em out? Is also good for checking the microwave oven. I let the Web do the 'running about'😉 In the meantime I found the little handheld analyser in the pic, covers 15 to 2700MHz. Cost a tad more than 10 bucks though🤔 Greetings from 'Up Over', Doug 😎

Hi Admiral RNinMunich sir, I was going down the route of building a 2.4GHz Detector/Meter until I came across this: It works a treat and for that price it is not worth running around getting parts for a diode/capacitor/meter circuit. Cheers from DownUnda

Quite simple Martin, there's a chip inside the Tester which generates the same signal as comes out of a receiver. The pot on the top varies the signal just like the sticks on the TX do. Mr Karslake just didn't know how to do it. A 'stick-in-the-mud! Guess that was one customer who wasn't😡 Working models deserve lights like the originals. Even boats like your Hornet probably had at least a white stern lamp to prevent them gettin' rammed up the whatsit😲 Was only pullin' your chain a bit about the LED tester and RF detector anyway😁 Ciao, Doug 😎

Doug, I'll stick with your build blog. I still don't understand how you used the servo tester to replace TX and Rx, but don't worry, I'm happy to use the RC gear. As I did tonight in fact. Hooked the FlySky up to a Futaba servo I'd put on the rudder for the Sea Hornet and it all worked a treat. First RC installation I've ever done! Made loads of statics, but no RCs before. And you will NEVER find lights on one of my models. Mike Karslake, life long professional modelmaker, to a customer..."Sir I make models, not bloody table lamps". Cheers, Martin

Hi Martin, would have thought the name was self explanatory! 😉 In the attached pic you can see my Robbe Servo Tester at the top. I used it to simulate the proportional signal from a receiver while testing your Taycol converter boards, not to power the motor.😲 Motor power came from the mains PSU in pic two, the battery eliminator circuit (BEC) in the ESC provided power to the tester. The tester provides the signal to drive servos, or in this case an ESC, and saves the faff of setting up TX and RX and fiddling with batteries when I want to test a circuit or function before building it into a boat. Cheers, Doug 😎 Oh, and by the way; when you get into lighting for your boats don't forget to buy an LED Tester as well 😁😁 You could also think about a simple RF Detector / Meter to check if your TX is actually transmitting 😁 Like I did with your TX using a home brew device - OR you could wait til I get around to publishing a Build Blog for the refined version I am making using a couple of RF diodes and a sensitive 300microamp meter 😊

What does one do with a servo tester? I know Doug used one to power the motors he was making pods for, for Gawd knows how. I have never heard of them. What do they test FOR? I'll soon need a special box just for all the test gear! Martin

Just for the record Sanwa Rx s are reversed too-----------Logically BTW Who makes the best type of crimping pliers for JST type connector terminals? All thoughts considered. Oh yes get a servo tester. Dirt cheap from about £2:50 on the likes of Bang Good, E Bay,Amazon. Really worth Having.👍
