Intermittent radio problems by robhenry Petty Officer   Posted: 15 hours ago
I have a real mystery problem ! Occasionally, one of my crash tender models loses control for no apparent reason. It is running on 40mHz Futaba system. This has been used for a number of years without any probs until recently. I have managed to reproduce the problem in the workshop just once. Effect is that using rudder channel, interferes with throttle channel such that when rudder servo operated the throttle goes completely haywire ! At the lake I have checked to make sure that no one else is on same freq. Most people run 2,4mHz anyway. When simulated in the workshop I have changed receivers transmitters and crystals and still had the problem. The next day problem had disappeared ! The other kit used in the boat are a Futaba rudder servo and two 30amp Electronise esc's running in parallel. Have checked receiver voltage under load--- no problem with this either. Has anyone got any ideas ? Any suggestions would be much appreciated. Rob

advise required by RNinMunich Fleet Admiral!   Posted: 22 days ago
OK. Thanks TJ👍 John, the old Sanwa receivers and servos have the + and - supply leads reversed as compared with all modern stuff, JR/Futaba etc!! That means that they have the negative in the middle of the plug and the positive on the outside, at the edge of the RX case! All modern kit has positive in the centre and negative at the outside, edge of the RX case!! Beware, I learned the hard way 😡 Tell us what you want to do and maybe we can help with wiring diagrams etc. PM me the details 👍 Cheers, Doug 😎

advise required by onetenor Fleet Admiral!   Posted: 23 days ago
I'll require advise soon as it's so long since I touched any R/X s. servos ,escs etc I've forgotten how things connect up. I don't want any magic smoke if you get me🤔 such as I bought some small J.S.T. connectors but are there adaptors to couple up to standard sizes? Are Sanwa rx's a different polarity to say Graupner,Futaba. Same goes for relays and B.E.C.s . I'll need simple circuit diagrams and all sorts of stuff. Sent in hard copy if possible with written/printed explanations. In colour would be the icing on the cake. Trouble is I'm as thick as the proverbial brick 🤓 Not just yet as I'm still housebound. I have some stuff already joined up that I can follow for some guidance at first at least. Anyone still up take a look at the lovely moon "Full" or close to it.

Servo choice for yacht by Westquay Fleet Admiral!   Posted: 1 month ago
Me again. I am finding the choice of servos mind-numbingly huge. I feel I should have a new steering servo for Vanity. I have a lot of other servos kicking around and I can only assume they work on a modern Orange Rx, but I'm thinking even a tight wad like me can justify a new servo. I would like it to be a bit lower than the Futaba I currently have out as it has to operate below the bottom of the winch drum and take two Bowden cables to the rudder as the rudder shaft is steeply raked, so only cable operation will do. Any suggestion welcome. I don't need speed or even especially accuracy, although reliability would be nice. 4.8volts too please. Cheers, Martin

Aerokits Patrol Torpedo Boat by RNinMunich Fleet Admiral!   Posted: 3 months ago
Hi MB, Sorry for late response, I've been occupied with varnishing and painting of my Sea Scout renovation. The Turnigy i6 and Flysky FS-6 are hardware identical but have slightly different software, not critical I understand. I have the German branded version of the Turnigy i6, called here HT-6. Attached is the excellent German / English User / Programming manual without the Chenglish gobbledygook! Flysky Chenglish manual also attached for comparison. Only mistake I found in the manual is re Binding (see pic); they mention Binding button on the RX when it is on the TX at bottom left Item 13 in the attached pic of my German branded Reely version. BTW; iA6 is the RX type number. The TX is TGY-I6 or FS-6 for Flysky. Pics 4 & 5 show my Reely HT-6 and Turnigy TGY-I6 versions. Identical except for labelling, same goes for the Flysky - see manual. Re: Servos: I have tested my TX and an iA-6 RX with all sorts of servos; Sanwa, Futaba, Hitec amongst others some going back 30 years and they all work fine. I currently have an iA-6 RX and ancient Hitec standard rudder servo in my Sea Scout and it works just fine. Re: controlling the ESC; it just plugs into the RX like a servo. Usually channel 1 or 3 depending on whether you want throttle on the right or left stick respectively. Re: 3D printed stuff 'brittle or not'; depends on what type of filament they use for the print so can't really say. Up to now have not had problems. What I have noticed with some 3D plastic and resin items is surface defects, pits etc, which need some treatment before fitting. Resin also tends to be more brittle than 3D plastic prints. Resin don't bend well and don't like knocks! As I discovered with the resin gun barrels on my Graf Spee 😡 Will be replaced shortly with turned brass or Alu! Re: LiPos; attached is a file from Model Boats mag of Hints and Tips for using LiPos. It also explains the tech jargon surrounding brushless motors, i.e. interpreting model numbers and parameters😉 All for now, cheers Doug 😎

Aerokits Patrol Torpedo Boat by canabus Fleet Admiral!   Posted: 3 months ago
Hi MouldBuilder As for radios they are the same, go for the Flysky. As for servos I think Futaba ones will work, but, the price of these from Hobbyking are cheap. The good balance will have auto cutout, but, check out club members to see what they use or model car clubs. The 1100kv has power to drive the boat. The kv rating is the base and multi by the voltage to get unloaded revs. 1100 x 11.1 volts(3s) 12210 and 4S(14-8volts) 16480rpm. Canabus

Aerokits Patrol Torpedo Boat by MouldBuilder Commander   Posted: 3 months ago
Thanks Canabus. I have just checked out the transmitter/receiver sets. Very reasonably priced. I really do want to upgrade. The Turnigy is around £40 whilst the Flysky is around £34. Do you have a preference?😊 Would my Futaba servos still work or would I need to change these also. I know this might be a strange question, but as you can see from one of my pictures above, I have a servo operating the speed controller. How do you control an electronic speed controller with the radio. As for the battery, is the safety bag used to put the battery in for charging in case it catches fire? I am a little wary about using things that I may not have control over. I have been looking at brushless motors. Can you say a kv range I should be looking for to possibly increase the speed issue. You have mentioned 1100kv and others above but was just wondering what you would cosider to be sensible bearing in mind only one motor is practical witout major hull surgery. Can I assume that if a motor is given a kv rating that all motors are based on the same criteria, or are there other variables. Thanks. 👍

1960S Taycol electric motor by jarvo Fleet Admiral!   Posted: 4 months ago
HI Mate, welcome to Mayhem, just a thought, I to prefer a period transmitter with my older models, I have a Macgregor trany which our club guru converted to 2.4gh with a Futaba module, works brilliantly, best of both worlds Mark

Krick WSP 47 by bilzin Commander   Posted: 4 months ago
Just about finished and soon to feel the water 'neath it's keel Note the Futaba FG7 transmitter now converted to 2.4 ghz and has performed faultlessly since I acquired it in the 80s Sorry about the mouthy woman on flog it and the noisy motor...greased it but still makes a lotta noise (the motor...not 'er)

Marblehead Sailboat upgraded by Ron Fleet Admiral!   Posted: 5 months ago
My friend bought this sailboat build in 1996 along with 15 other boats at Port Credit, Ontario. My friend Ewald Bengel and his brother Fred, bought the sailboat with R/C equipped, but older Futaba AM but usable. The boat needed structural reinforcements, several new bulkheads, R/R rudder block and repair the rudder. They are not racing the boat intending to keep it at their summer home on the lake. They had me add a Birch plywood deck and hatchway. Progress is being made.

Layout and Limitations (con) by NPJ Captain   Posted: 8 months ago
These are what I have available. I was going to kept the Futaba for the Yacht, but I believe they are both 6 channel. What do you think? NPJ

Hobby Engine Richardson Upgrade by NPJ Captain   Posted: 9 months ago
Good morning folks. Well a few (3)decisions taken on advice:- Futaba Tranny 6 channel and receiver Larger battery pack, going with NiMh rather than Lipo That gives me something to do in the bottom of the boat when I take the lid off.................... All this started with tidying up the Smaragd sail boat, so seem to have lost track a bit. However, Tug Boat much easier to manage on the bench and if I have you chaps helping over my shoulder, I am happy! Next two questions to those using/used such boats. What about having independent motor drives to improve maneuverability ? Increase size of rudders? I must now go and spend some money! Regards to all. NPJ.
