Delta Force 33" Prop

[Raydee]

Just curious to see what prop guys are using on their Delta Force 33" hulls? If possible post your Motor and cell setup too.
So far on my hull the only propr that I have run are a couple smaller 2 blade props (645-647) and a 447/3. The two bladers were not real good and the 447/3 seems to run pretty good. I plan to try a couple different larger 2 bladers tomorrow. I am running a Neu 1521 1.5D motor on 4s lipo.

Neu 1521/1y 6s2p

I am running the Speedmaster stinger but am having a really hard time dialing her in. I just bought a Speedmaster strut from OSE but have not installed it yet. So far the best prop I have run is the M545. Really good acceleration and top end also. I cannot wait to get her trimmed proper.

1515 1y on 4S so far a prather s220 is as far as I have gotten. I tried a 445 but lead to chine walk and raising strut just caused speed loss. I love the DF hulls. Great size range and they all seem very competitive. I did learn that a "M" series props just terrible for some reason. Just on my setup at least.

I had no luck at all with 3 blade props on mine. I was running the Neu 1910 .5y (2100kv) on 4s2p. It liked the x447(54mph) but was blistering fast in the x452(58.5mph)

1521/1.5d on 2x 4s 4200/35c G3 packs,,, turning a x450 2 blade,, got 58 and change.. I am running the Storm hull and it seems to like 52-55mph and runns solid as a rock! Running 58+ with that hull in race water gets exciting..

[Raydee]

Yeah I am going to try a x450 tomorrow for sure. How are you temps with that prop?

Motor 110-118,, esc 120-125,, lipos 112-115..... If I am on/off throttle alot in a heat,, I get upto 130-135 on esc,, 120-125 motor and packs stay about 112-118...

My fav. prop for that setup is a x447/3 with 1/8" backcut and rounded tips with slight pitch increase.. Boat runs super smooth and no torque roll at all.. 51-53 mph with this prop,, pitched up it is 55-57mph...

I'm running a X447 mildly cupped with the 1521 1.5D. Good speed & pulls through turns way harder than with the 2-bladers I've tried. Temps just fine for oval heats. I have a Sholund X450 cut down a smidge, but ran hot with the old 1.03 timing on low-[actually was too high.] May try the X450 this weekend at the NAMBA 2-Lap, but Darin's got the record pretty tight & I drive like Helen Keller :doh:

Larry you seem to have the hottest setup here have you been able to get into the 60 mph bracket with your DF33 , I see a lot of low to high 50's but no one has stepped up the the 60ish podium

[Raydee]

Larry after talking to you on the phone I think you wrote the wrong timing value down for the D wind motor.

Thank You Ray
14 degrees is on my "Y" winds
I set my "D" winds at 2 degrees


Peter this my OVAL race setup, I have never put a GPS in it.

But I did set a new 1 mile oval record at the NAT's last weekend with it.

Well just back from the pond. I tried the X450 and it worked ok but a little sluggish in the the turns. Probably a couple MPH faster in the straights over the X447 though. I thought I had a X450/3 in my box but it was a X452/3 so I didn't try it. It just seems like my Delta is a bit slugish, might be because all I really run is hydro's and they scream? I really had to get my trim tabs down some, i had them all the way up and the boat was way to wild in the turns...and even in the straights for that matter. When I move the tabs down so the boat is nice and stable it just seems slow to me. I will post some of the wild vid with the tabs up to high.

Mine is doing the same thing. I thought it was in my setup so I purchased the strut from speedmaster and replaced the stinger. I never did get her settled in with the stinger. Hopefully the strut will do the trick......to be continued.

[Raydee]

I did some trim tab adjustment tonight and it calmed right down. I def don't think the Stinger is a problem. I have seen many mono's with stingers run great.

[tth]

I may try running her on 4s2p for a while? I did try adjusting the trim tabs to no avail. I only have the innermost pair installed right now. Tonight I'll put on the outer set and give it a go.

[Raydee]

If you are having a problem with the hull in the turns then the outer tabs def help. I adjusted mine a 1/4 turn at a time tonight until the boat ran where I wanted it. I wish my woman would have took the vid cam to show the difference.

I do get alot of chine in the straights and its just horrible in the turns. My DF29 has regular old Fullers mono hardware system. This 29" hull has seen a tad over 70 and is straight as a bullet when setup on 8s1p. When I poke along on 4s2p ( with a higher kv motor ) I am low 50's and don't even come off the throttle in the turns??? I will have to get my wife to shoot some HD video so I can post them and get some good feedback from you guys as to what may be going on.

Are your batteries inside or outside the rails ? Once I moved my motor to the back & placed the batts on the centerline, the wobble stopped.

Apologies for clogging your thread Ray.Here are some pics.....

What is a good prop deltaforce 33 " cyberstorm ? whether octura x440 / 3 prop too small for that?

Esc hifei swordfish 200A 3-6S and scorpion hk 3026/2300 kv motor or that castle creations 1717 1580 kv ?

[highflyerbill]

My DF33 likes 3 blade props . It's running a Lep 4082-1600kv 180esc with 11 deg timing 6s2p lipo . For heats I use a 447/3 cut down to 445/3 Makes for a fairly fast and very happy boat in race water . It goes where you point it When I first put the cut down 447/3 It chine walked badly . I was advised when you cut down these props they will gain lift . I added a small amount of positive angle to the stinger and no more chine walk . I think they make very completive boats .

whether their own videos from your boat?
