Here is my recommendation on the radio, as its what I'm using in my boats after doing a lot of research... used it end of last year and am in love, I've owned 3pk, 3pks, 4pks, M11r, and this is my favorite for ease of use, and great range... while still looking good.

They are a $200 radio (after discounts) they have telemetry, and the range is absolutely impeccable... and yes futaba quality. The menu isn't so crazy to use like a 4pk, yet it does have a ton of adjustments but is much easier to set up and use with boats... the nicest thing of all is instead of using Fasst, they use FHHS.... Same range as the Fasst but the rxrs are soooo much cheaper... they have like .002 seconds longer transit time lol, still better then most any other radio... they are a phenominal radio... so much so that if you were into car racing you'll notice many of the top dogs running them at the local tracks, the only ones that don't are the sponsored guys who get 4pks's for free...

here are the rxrs..

Also to note is the "air" receivers also work with this radio (perfect for our boats!!)... there is a lot of info online of 4pls lovers, ALSO big NOTE that the air version rxrs as below have built in voltage regulators meaning you can run a strait up 7.4v small lipo pack directly into the rxr to power your opto esc and servo!... wish they would promote this more, you'll see in this next link if you scroll down and read specs how it even states it works in high speed mode in 4pl radios only ..... I cant say enough good things about this radio.

you won't notice your transit speeds slowing down with this radio! When your boat is at the other end of the pond the steering is as if the boat was sitting right next to you!

yup they are the cats meow :) as far as I'm concerned..... I found this stuff out and now own a Futaba "aircraft" radio too... of course I have spectrum to for the BNF models. I highly recommend this radio, has a GREAT high quality feel to it and great looks too... makes our toy boats look pretty snazzy !

Thanks

[dude123]

Whats the difference between the mr300 and the mr200?

Whats the difference between the mr300 and the mr200?

Mr300 is a 3 channel rxr, mr200 is a 2 channel

Hey guys so i was trying to get my servo mounted with no zi ties and i noticed that my pish rod is wack. I just dont like it do you guys have any pics of one that was used in the daytina i am using a kintec servo mount whih is making it rather difficult. Thanks

[dude123]

I thought i would update this thread today, so latly i have been running ut as much as i can which isnt that much and i keep on running into this issue!! Every time that it starts to get up to speed it stsrts to turn or the rear end stsrts to swerve, i am thinking my prop could be to low or maybe something is wrong with my rudder but i am not completly sure. Any recomendations would be great

[TheShaddix]

There could be a few things happening... One, your rudder to servo connection is weak so at speed the water turns your rudder instead of it being straight. Check the linkage. Also make sure you're using a thick enough rod and there is no angle to it, and check if there is any play where the rod connects to the servo horn. Show us a few pics of that area and where it mounts to the actual rudder arm.

Another reason could be that your rudder gets a lot of prop wash. Some of that behavior that you described is completely normal for single motor setups as the boat would travel straight at slow speed, but at higher speeds it starts to turn a bit. However, that should be very minimal and hardly noticeable. I am not a fan of offset rudders as that, in itself, could be the reason to your problem. The rudder creates drag on one side of the boat and turns it. Also try sharpening the rudder blade just a bit to reduce drag. And you could also try shortening it slightly.

Check that nothing is obstructing the movement of your servo arm. From your pics it looks like a mess with wires, etc. Also check that the rudder rotates freely when it's not connected. Sometimes there is drag in the pivot point and that will hinder the self centering feature.

Another thing, and that's probably what's happening, is your servo got wet and is acting up when the throttle is pressed. Check the wire plug to your receiver for any corrosion, spray with corrosionX and use a bristle brush to clean.

If all of the above fails, try a different (better/stronger) servo such as hitec or something similar.

And from the video you posted, you could try shifting your batteries a bit more forward towards the nose. That should help keep it more planted.

Ok thanks i will get some pics when i get home. I am using a 4-40 push rod but i dont think the bends are good at all i am using a offset rudder so i dont think prop wash is the issue and i think i need a better servo the one i am using is a cheap hitec one i believe its like the cheapiest one they sell. It iddnt do this for the maiden and i had oppened it up all the way so i had to off done something that acrewed it up.

[TheShaddix]

I meant the offset rudder could be the issue. But since you said it didn't use to have this issue, then that's out of the picture. Sounds like your servo is either glitching or just not set up correctly or is too weak.

[dude123]

I think its all of those things it was a really cheap one. I need to do a better job with the push rod its hard to know how many bends and were it needs to be and such not for me

[dude123]

Is corrosion x only sold online or can i get it at like homewdepot or lows?

[TheShaddix]

Can use wd-40 as well. With a brush you can clean those wire connectors nicely. Whenever you have any sort of glitching in esc/servo/rx, it's almost always due to water getting onto the wire leads or inside of the receiver. I remember i was having some bad esc power cutouts at speed where it would stutter every few seconds at full throttle. Turned out that my connectors were corroded. Cleaned them up and that solved the problem! Since then I just waterproof them by epoxying the area where the wires come into the plastic bits, then sealing both connectors w/ liquid electrical tape and heatshrinking over that once they are plugged in (when you're using extension wires), and do waterproof your rx either with a balloon or a traxxas rx box (Best way i know of). Of course it's better to keep the water out in the first place! But this is just an extra precautionary measure.
