HI again, one pressing question I forgot to ask in my earlier post is the paint style of the Black & Red
Does the black of the sides extend parallel out to the bows
or does it curl upwards to follow the line of the chine stringer?
There seems to be a good number painted both ways..

I would like to know how owners have fixed the mast to
their Fireboat?
I have made a brass one - fairly sturdy, but have not been
very successful In keeping It In place, bearing In mind that I
have restricted access on Inside of cabin roof.

๐ What size Esc
13 years ago by
๐ฌ๐ง PeteG (

HI Dave,
The transmitter is an Acoms Techniplus with, as you say, an additional push setting next to Ch 1 control stick.This may be more suitable for cars-I dont know.? At the moment it is set to the UP position and that is where it has been while setting up the ESC. if I move this to a fully down position it moves the control stick down further and limits the reverse movement of control stick. So I am not sure whether to do this.?
I might switch back to using a Futaba T2ER which has been ok with me so far.?
Today though I have replaced the motor with A Ripspeed 600 8.4v and reset the system from square one. I now need water to test properly. My post here relates only to a refurbished Fireboat - I may have confused you with an earlier post enquiring about ESC sizes.

๐ What size Esc
13 years ago by
๐ฌ๐ง PeteG (

HI Dave,
I have been looking at a much earlier thread/post of yours regarding ESC set up.
This week I took out a refurbished fireboat complete with all new electrics for its 1st sailing. it performed very poorly, it did not plane at all because it was too slow.
I am lost with this at the moment - it has same set up -600 Speed 8.4v as my own Fireboat with a 25A esc.
On reading your post from last year you talk about motor/prop rotating in wrong direction? and the need perhaps to reverse wires comimg from ESC to the motor?
Can you tell me - What is the correct direction of rotation of prop when looking say - at the boat from behind the stern end then please.
This might be the answer to my problem as it crossed my mind that it seemed to have more revs in reverse!

I would like to know the criteria for choosing the size of an ESC for my boat or your suggestion for this size boat.
It Is a small 20" high speed launch - name and make unknown by me - and fitted with a 400 Speed Graupner 6v motor. I can post picture tomorrow.
Many thanks/

Hello,
D'you know, I would really like to do that modification to roof as you describe and your pictures show the result well. I would like to know how you took the roof off too. I just might be tempted to add a searchlight and aerial.....
There appear to be serrations down the mast legs and is there a cover over them too (white)?
What arrangement is there for holding the mast upright?
I am using 2 screws in each leg.
Thanks,PeteG.

Hello PM, Twice I have accidentally caught the mast and knocked it off the roof!
So, as you suggest I have drilled and fitted 2 small spigots (10ba screrws) to aid a firmer fixing of the brackets on each side before glueing. I couldn't face taking the roof off at this late stage but maybe next time........!
Many Thanks.

Hello Dave
Thanks for that useful explanation - what happened is I used this Acoms set (from Ebay) and just tried it out on a boat with a Futaba receiver already set up.
So in effect I hadn't set up the Acoms set with the Esc (Viper Mtronics 20A).
This may (?) account for the trim adjustment I had to make in order to stop the motor running!
I will be installing the complete Acoms equipt into a new boat shortly so I'm hoping it will function properly.

Hello Dave,
Having just acquired an Acoms handset and receiver I find that a Futaba servo will not plug into the Acoms receiver! Slightly different shape plug casing.
That apart, seems I have to have the trim lever pushed all one way to prevent the prop from moving when not touching the controls?
Is there another adjustment?

Hello Roger,
I do like to keep busy during the summer so I have been working on this Launch in between trouble shooting and running the Marlin & Fireboat.
Actually I have now got the Marlin running well at last after changing propeller and uprating fuse to 20A much like I did with the Fireboat.
This boat has been great to work on and has never seen water yet! Very soon it will earn its keep for me!
You can see the transfers in pic 1 - thanks for the info Roger - much the same procedure as it always was then!
They are a bit yellow with age but they are going on despite.
I'm going to start off with a 550 standard motor running on 7.2v. if all goes well I might then uprate to a 600 Speed 7.2v Graupner which runs at much higher rpm. What do you think?

Hello Bat 44,
An Impressive fleet you have! I do like the Fireboat of course - with that equipment stowed in the well. Mine is rather plainer at the stern. Are you planning on painting this one?
The Sea Urchin has that classic look of the Aerokit collection - I haven't been able to acquire any of these boats yet, but that will be my task over the summer and beyond.
Many thanks for sharing these pics.

Hello Bat44,
There seems to be a lot of boating action up around the midlands and the east, they are all a bit too far for me to travel to from Kent otherwise I would like to be there Ie Fireboat funday and Wicksteed etc.
Yes, the prop by all accounts is the wrong type for the boat. Thats actually good news - I can put that right!
Looks like a 40mm standard will be fitted.
What does your Aerokit fleet consist of then?

HI Bat44
I am going to try one of Dave's surplus props which he has kindly offered! This is what I am currently using - 45mm across tips of blade M4 - its a bit severe looking (is this a cleaver prop? ).
The run time on my boat isn't actually that good so this may be the answer.
As regards balancing that will be a no, I haven't got that far!

This is an ongoing problem now as I experienced more hesitant running again yesterday (hunting). Blew a fuse too but this time I had feathers wrapped round prop!
I could try changing propeller as you say - what is less pitch? How is pitch measured?
I am running with a 45mm dia prop now - not that oversized I feel.
I have larger Esc but not fitted yet.
Actually found a problem with the Esc on/off switch - it had poor connection so this has been ditched and replaced.
But your prop suggestion is, as you say simple and cheap. I will try next.
Many Thanks.

Hello bat44,
I did run my boat yesterday with new motor as a starting point to troubleshooting. it ran fine, however I was wary about running it too fast for too long. I might well change the Esc to a 25a - that sounds a likely cause to my problem -many thanks.

Took my fierboat out today despite very gusty conditions at Blackheath pond, under full power boat again behaved in a hesitant manner but ran beautifully in between. Then, no power at all and drifting in the wind in centre of lake!
Managed to nudge it back in with my grandsons launch after 20 mins.
No obvious overheating on any cables or motor(warm but not hot) but on checking fuse (15a) found it was blown.
No idea why yet. What to do next?

I took out my fireboat again today at a local lake. As in past weeks it has sailed very well but it has a habit of "hunting" under full power. I have fitted a fully charged new battery, transmitter is also fully charged. it runs fine for a time then seems to lose power momentarily then picks up again.
Does anyone have any suggestions or likely causes please.

Hello Paul,
I have managed to Improve the connection by using a heavily soldered connection onto a gold plated sprung connector. The connector itself though did not allow any mechanical connection only a 'well' to run the solder into.
This has eliminated nearly all heat at the joint.
Thanks for your help.

I have just carried out a water test to check for any flow through the cooling jacket. it was minimal at this point in bath!
What has alarmed me a little is how hot the connection to ESC became (one side only). On checking I found the bullet connector was just not connected at all well?
You can see the poor connection in picture Ie. the bullet connector had parted company from the cable as I pulled them apart. Can anybody suggest or recommend a better method of connecting the two cables from ESC to the motor? Most of the trouble I have had with the electrics has been at this connection.

Hello Dave,
I did wonder about glazing because I bought that set of windows and frames from this website to use eventually!
I think I might just glaze the cabin and front of boat and leave the rear compartments unglazed -its all a bit cosmetic anyway!
I thought I would varnish the hull inside and out as a final, late(!) precaution. I did not get round to putting resin down on the inside floor - do you think I should have done so?

Hello Dave,
I have actually completed all the wiring connections today and have tested and set-up the transmitter speed control and rudder orientation. All seems ok at this point.
I note your comment about ventilation around the ESC - well of course it is in an enclosed compartment mounted on a block away from hull - do you think piping an airflow from above via tubes would be practical or necessary?

Hello Dave,
I have finally got the rudder and servo set in a suitable
position -with your help and my local model shop I now know the basics of setting up! I have got rudder and servo arms set at equal distances now and movement is smooth, if rather a lot of it!
I have started wiring up some items today, leaving all fixings loose until I get a satisfactory and tidy layout. Will need to build a support block for ESC on hull floor. What glue would you use here?

Hello Dave,
I have repositioned the rod on servo and rudder arms several times -I might just be getting near to an optimum position thanks to a post from Roger. I take some comfort tho' from what you say regarding having too much rudder movement can be disastrous - I seem to have ample movement either way now plus the set-up instructions with the ESC describes how to set max speed point on 1 channel and hopefully provide a calibration for max rudder movement on other channel too?
I wish I could have sailed on the lake today! Some way off yet. Have to fit fuse in power line too - need to do some wiring for that! The battery and Esc connectors are a mating pair too - now have to break into one wire for fuse.

Hello Roger,
I found that info a little hard to follow at first! 15-16mm from centre of screw to where rod joins servo -ok. Similarly for rudder -this dimension happens to be wildly different on my set-up. Im beginning to feel seriously lacking in knowledge here!
I have several close up pictures before I dismantled the original setup so I might just resort to resetting it to that.
Not been a good weekend!
Will try again with the lube operation.
Thanks Roger.

Hello Dave,
I am most grateful for the info that you post - none of which I take as a criticism- far from it! I did think it was a fairly original model as it came with some nice solid brass fittings Ie. winch and tow hook.
I have not had much success though in moving the servo. I'm obviously not getting the right positioning - it keeps locking up on movement before I reach a correct position for the rudder at either extremity. its not been very satisfying so far.
Now I am lining up the motor and coupling in order to secure in position. it looks ok with very little end float!
Motor spins fine under power, whether it gets too hot remains to be seen at a later date. Unable to KEEP vaseline in the shaft tho' -pumped in plenty but most of it came out again once shaft fed back into tube?
Servo may remain put for first sailing.
I too will use velcro to secure Esc and Receiver - its all very convenient for me and effective.
