These FireFighters Are Awesome!

i used the marine specilities strut and a seaducer rudder on mine. I think I had to take a tiny bit off the rudder bracket on mine..... it was so little i did it with a sanding block.... about 1/16" i think right? The speedmaster stuff is great also but i'm not sure it would be smaller?

OK,

I used the Seaducer strut but I think it is too wide - Oh well - the holes are drilled so I'll have to use it. I will have to make a new rudder bracket for the seaducer rudder - it hangs out by approx. 1/8" with it butted against the side of the strut mount

look on the first page of this thread to see my hardware..... i think i simply sanded a little off the strut and rudder to get it to fit.

Tom,

That strut bracket looks narrower than the Seaducer item - that is probably the culprit. Shame I drilled holes in the transom before checking it! I'm definately going to need a custom rudder bracket to get around that little problem.

Tim,

Do some pretty pictures. I have been know to make hardware!

Nitrocrazed racing: Need to make a fly cutter.....

 

[TimD]

Ian,

I can probably make the rudder bracket myself if I can locate some of the aluminium angle needed. Shouldn't be too difficult with the drill press.

Thanks anyway!

Tim.

 

[Ian Inverarity]

If you cant find appropriate angle, let me know. I have all sorts of bits sitting around... ;D

Nitrocrazed racing: Whey use a drill when you can use a mill.... 8)

strut bracket was identical.... i just picked that one cause it matched my engine head..... you should have the same stuff that I have Tim.... I can work with wood all day long and do a great job..... but i'm an idiot with metal..... so if i can do it you surely can! like I said.... i used some 60 grit sandpaper and got mine to fit.

What other hardware is available that would be narrower?

 

[TimD]

Tom,

The strut bracket on your pic is definately different to the seaducer one I have - your's is T shaped where as mine is 2 90degree brackets that bolt to the strut blade. No Big deal really - a different bracket for the rudder should do the trick!

Ian,

Thanks for the offer - I might have something but I'll let you know. Can you mill some engine mount parts for me? I don't like the solid engine mount - especially with the micro servo's for throttle and mixture.

Tim.

 

[TomMoorehouse]

oh yea.... now i remember..... use a one sided strut bracket???

Tom,

How long before the FF .21 is ready?

I thought about doing that but have doubts about it being reliable/ strong enough.

Last week I got some right angle Carbon Fiber from a guy on eBay. I bought it just for trying to make some rudder and strut brackets. He sells pieces 1"x1"x12" and .062" thick. He also sells CF sheets also in there in the R/C boating section. Graphite Excellence is the one to look for. If anyone needs his e-mail address, I can look it up.

Sounds good but I have a bad feeling about ebay'ing internationally........

Got any spare that you are willing to part with and prepared to ship o/s?

Hey Tim, Ive been running a single sided strut bracket on my .21 for a year now without any problems. Its half of a speedmaster strut bracket. I had a problem with my rudder and strut bracket being to wide also, so I had to do something. seems like it would work on a 12 just the same.....

I did knurle the two faces of the strut and bracket just for the heck of it.

James,

Are you running a square drive? My concern is that with the thrust acting directly on the strut with a square drive, that the transom might be distorted or fail.

Oh yeah - this is a .21 boat too!

 

[topfuel443]

hhmmmmm........ I guess I missed all of those details. No its not square drive, I use a "regular" shaft with a collet. Your guess is as good as mine. So you are putting a .21 in a .12 firefighter rigger? Or did I completely strike out on this thread?

James,

This is a FF21 ;D

My friend Tom let me buy a "proto" 8) Shame it's taken me so long to build it but the idea was I can run all year round here where as Tom can't due to solid water.

TimD racing: worlds slowest builder.

 

[TomMoorehouse]

Tom,

How long before the FF .21 is ready?

-MikeP

Well.... I think I got my kit cutter pretty excited about it at the hobby expo.... I have my hopes it will be ready in say 2 months???

TimD..... yep he got a proto..... he was supposed to get his done before me cause I was going real slow.... oh well..... consider it Tim's reward for being #2 poster on the board

as far as square drive.... i dont know.... I never used it. I'm sorry that stuff didnt fit..... I just plain didn't know that it did not. When I asked seaducer..... at the time they made the roadrunners.... they said it would fit the roadrunners and I asked about the tub width .... guess the firefighter tub is skinnier than a roadrunner extreme.

sorry bout that tim.... :-[

 

[TimD]

No sweat Tom - I'll make it fit!
