Can't pull a 1450?

[Terry Flynn]

I've had a 20 Hydro for a few years and I just haven't run it that much afraid of it and just the lack boats . well this weekend I ran it at the Marquette race and I had a blast. Thanks gooycheese.

The question I have is every one I have talked to said to run a 1450 I had bought a few props from Andy and a few from Mark. I cant get the boat to get on step. it will run with a 1445?

The boat is a SGX 21. Novarossi LS worked over by Rod Geraghty. OPS 3280 set at 3 1/2 strut is were John Brown said to set it at. the boat is 4 1/4 LBS

The boat runs good with the 1445 but would like to figure out why it wont pull a 1450.

Thanks for the help

Terry,

Send me the 1450 and I will be able to tell you why it doesn't work.

It should work very well,I would bet it is too big in diameter. The H-4

and H-5 work very well on that set up.

Thanks,

Terry,

Good to hear you had a blast with the B boat. They are a lot of fun.

To pull a 1450 it will probably have to be de-tounged to get it to launch and also make sure you're good to the rich side going in. That's a whole bunch of prop.

Try a little cup in that 1445 you may be surprised.

Good luck

ABC H-7 reduced to 46mm dia, with 3.2-3.5 cup is another great prop for your SGX. Richard D

You could also try raising the strutt 1/32 to 1/16 and see what happens.

Most often the 1450 has to be reduced to about 46MM to get it going well. Stock size is many times just too big a diameter. You can take a 1445 and pitch it up a lot and get nearly the same results but the reduced 1450 is better. The H-7 is excellent too.

Thanks for the help guys.

Mark I have to apologize I was digging around tonight and I found the two props you did for me one was a 1450 turned down I don't remember the size I lost the bag the other was a ABC 1816 -45.18mm with 3.46 pitch. the one's I tired were AB 1450 with 3.8 cup and 4.0 cup them were the one's I couldn't get it up on step with. I have an H-5 and H-7 I'll try this weekend also.

Thanks

Terry,

Send the AB 1450's and I will repitch them so they work very well. It will only cost

you a stamp.

You need an AB 1450, 46mm, 3.6" pitch. If Andy did cut down the diameter then I would probably get him to repitch them.

So, is anyone running a true 1450 on a .21 rigger for heat race conditions????

If the 1450 is full balde it is too much and even if it is cut to 46mm, it takes a healthy torque engine to pull 3.8" cup.

For heat racing stick with the 1445's....Save the work and $$'s of cutting down big props.

We've runs fast as 74 mph with one on our Nova/SGX combo.

I won the 2004 world champs with one too.

Chris's Blackbird, set-up properly, with a good Nova motor, and 3280 pipe, will pull 1450's with no

problem. Ran mine today with 3.6 cup, several times, no problem on launch.
