.21 Fire Fighter
After taking the summer off, I'm getting ready to complet my .21 FF that I had started last winter. I noticed a previous post of a pic of a .12 FF (really nice!). does anyone have pics of thier finished Outriggers? Pics from all angles and descriptions of how you have set up will go a long way
Thanks in advance of your help!!

I have a .21 OS max RG that I'm stripping out of a v-hull I had laying around. Once the weather tunrs, I'm hoping to put some time on this project. I've enjoyed the build out on this project so far....good kit, good support... good fit!

A .21 buggy engine, that was what I wanted to run too as I have a buggy engine in my FF.12 but I was told by Tom (the designer) if you try to use a .21 buggy engine "the tough part is the flywheel, then try to have one with a rotary carb.... or you need a bell crank and that is a real pain!"
I sure do like my FF.12 just looking to step up some to a .21.
Just some info

RE: .21 Fire Fighter
Hi Mark,
Just wanted to say Looks Great !!!
I have some questions,
1. How are your rear sponsons attached? The AOA looks like it may be a little high?
2. Where is your center of Gravity? I am have understood it should be at the center or trailing edge of the turn fin?
3. Based on the pictures it almost looks like your stuffing tube stops in the radio box?
4. What type of pushrod seals are you using, I cant see any?
5. Am I not seeing a nose on the tub?
Some recommendations,
1. You might wanna consider using some spongy type foam to rap your RX to dampen the vibration, and also pin your battery in place so it don't bounce around.
2. I am not sure your boat is ready for water but you might wanna make sure you have a 1/8-1/4 gap between the drive dog and the strut ( cables shrink when running)
3. I have run into this problem alot with riggers. You might wanna make sure your radio box is totally water proof before you run it, water in there will create a hell of a day for you.
Paul
p.s. can we see some pics of the inside of engine compartment and some side shots of the transom/sponsons/strut?

RE: .21 Fire Fighter
good day.. & thanks for your input Paul
the rear sponsors are attached with thin double sided foam tape. What is AOA?
The center of gravity is right at the back edge of the engine compartment
yes, my stuffing tube does stop in the radio box (I'm thinking that this is not a good thing [X(])
In my haste to "say" I was done, I did not instlall the rubber boot seals, balloons for battery box and receiver and foam for the radio box..
I did not install a nose. I must of missed it in the instructions? Not a bad idea and can easily be done
I've adjusted the gap on the drive dog. thanks for that as this is my first inboard

RE: .21 Fire Fighter
Mark,
Like I said your boat does look Great !!!
I would figure out how to get the stuffing tub thru the radio box. AOA is angle of attack, that is the angle at which the sponson contact the water. I will say I start building my FF.21 on Jan 1st as part of the build challenge on this forum. I have built the FF blazzin .12 , I understand now that the way the rear sponsons appear to run are different than on the .12 model. I did notice you do look like you have the rear sponsons a little deep, they should be about 1/8" above the bottom of the stuffing tube as it enters the strut. These pics are of a FF blazzin .12 so they are a little different than your boat but you can get an idea of what I am saying.

RE: .21 Fire Fighter
I can bring the rear sponsors up. I thought I had them set about 3/16 above but you are right they are not. I brought the rear sponsors back as I did not want them to cover the lasur cut FF logo. Will this pose a problem?
Sean, the turn fin spar has a fibergalss plate in the middle
Paul, nice boat! and I like that stand. I also needed several of your pictures you have posted on itnl'waters in order to complete..thanks! any other suggestions will be appreciated

Boatnutz, every rigger is a little different, my .21 Hawk has run everything for a ABC H-4, H-5 and even an H-7 depending on your setup and how strong your motor is. Mark Sholund from props4u did a fantastic job on my H-4 & H-5 props.

RE: .21 Fire Fighter
After clearcoating mine last week, she is already to be put back together again.
A little bit of white pearl was added to the clear, she looks better in the sun so it is my intention to get some more pics in better light when she's all back together again.
I decided that I "needed" a FF21 just so the FFGas that I running doesn't get lonely at the pond
I've got a nice little Rossi 21 with an AB billet pipe to go on her. At this point it is hoped to have her out on the water for tweaking next weekend.
Having not run nitros for quite a few years now (only Gas), I have forgotten just how fiddly these lil fellas can be.....................space is the luxury of the gas boat, but we'll get there I'm sure. Really looking forward to running this one.........................she sure has re-ignited my motivation for nitro boats
