anyone local to me got 27mhz tx with a lot of crystals to find out my boats rx frequency
-
There should be a number on the crystal ! also you would need to think is it AM or FM !
-
nope it s a chinese receiver lookin to use a 27 meg tx acoms futaba to find it would need sets of tx crystals
-
Hi again,i have just spoke to my friend,he has lots of 27meg crystals tx & rx,he will put them in sets tonight,so if you can wait till tomorrow and i will let you know what there is.baloo
-
i only need tx and a transmitter as i need to keep cruddy chinese rx with built in esc
-
No probs leave it with me until tomorrow,will sought something out
-
If it is a non crystalled receiver it will most likely be AM and will receive any signal in the frequency band.
You will find that any crystal in a futaba tx will operate it but so will anyone else on 27AM on the lake.

so it looks like im screwed

Not completely.
It might help to name and shame the model as there maybe a mayhemmer who has modified the same model.

Speak to "howes models" at kidlington oxford.They do NQD models,they might have some spare parts.

<<Full Function Radio Controlled (Control forward , left and right turn, stop)>>
From the "Features" on the link.
From that I would guess that the encoding used is the maker's very own, and nothing like a standard hobby setup, plus very rudimentary control, if control is the right word.
<<Outdoor operating range up to 300 feet away>>
About 100 yards, so neither a high power transmitter nor a sensitive receiver, and from that, probably not selective either, so prone to interference from anybody else. A working TX might also upset anybody else at the pool due to uncertain tuning.
<<High speed servo for rudder control for great maneuvering capabilities>>
So there is a means of controlling the rudder, probably not proportional.
so it looks like im screwed
Depends on your definition. Unless you chance on a matching TX, it would need a refit, probably along the lines of a 2.4GHz TX and RX set, plus either switchers to work or replace the existing relays which would give the original dodgy control, or ESCs and a mixer to have it go like it shows on the box. And a servo to work the rudder.

now i wish i didnt have it
-
what a toodo which way to turn
option 1 replace 3 motors with 1 or two brushless fit servo and 2.4 gear
option 2 crack on with some 27 meg gear and switch on switch off micro switch and two servos
option 3 find large bin
-
id go with option one , at least you will have some reliable equipment , rather than the hit or miss product that it was originally supplied with !
-
2.4 radio 2 servos, 1 rudder, 1 controlling the single central motor via micro switch fitted with staggered cam then it wacks in two motors on outside any comments
