I think Jays friend is using the castle 2028 800kv motor. My motor finally got here and I have got some testing done. The motor turns the 7016 props no problem. The guys here think I'm hitting 70 at the end of the back strait. I'm waiting for Brian B to make me a 2814 ABC prop to try. I'm not having any prop walk problem. I must say the boat takes off out of the hole very nice with the big prop. I think big boat conversions are going to be very easy for guys wanting to convert gas size boats on the cheap. TP now has a 5870 motor and I'm going to give that motor a try too. But for you guys wanting to go real fast, TP has a lot of KV options to target your max rpm and will swing the bigger props doing it. I'm going out again today with the castle 160 esc to get some data from the boat.

I think I know 2 of them. One has a backlash with an older 2028 and the other has an FM1 with a 3080 6 or 7 turn. The FM1 is extremely fast and I have yet to see it stay opened. He's using gas sized props on 10s. The backlash with 2028 runs on 8s if I remember and also gas sized props. I personally have a backlash with Lehner 3080/8 which is 656kv loaded and I run the same props the big blocks run, PWW 6719/3 654 on 10s. I have no issues staying in front of the gas boats :-). The boat in my avatar is the one I run.

I also have a cat with a 2028 800kv I run with smaller gas sized props, PWW 6516/3 350 on 10s. It also has no issues staying in front of the gas boats.

I got the data from the Castle 160. I was running a prather 270 that I rounded the tips and back cut the trailing edge a little. Dinogy 10s 10,000 mah 65c older packs and not my new graphene packs.

Volts was 38.1 avg with the lowest I could find on the chart was 36.9
Ripl. .20 avg.
Current was 102 avg with max 210
Temp was 96.2 avg /121 high
RPM this one makes no sense. It says 12,284 avg with 26,794 high. I have motor set to 6 pole and 650kv
The castle had no problem running this prop but it's not the prop I want to run. The 7016 and 7516 all make the boat fast but not turn good. The best prop for turning was a 2514 abc prop which is only 63mm and too small. Brian is making me a 2814 3 blade which I think the boat is going to like. It's been my experience racing monos that they like props with a 1.4 pitch ratio.
I'm very happy with the motor so far and just need the right props now for racing conditions.

mark, what do you mean not turn good?

[MarkF]

I mean the boat does not turn good in the turns. High lift style props lift the back of the boat making the front of the boat drag in the water in the turns.

Fitting everything into the tub will likely be the biggest challenge. Suggest 10S2P with a minimum 7000 mAh total and minimum 60C. The TP 5670 if you insist, Kv 850 is probably best. This Kv powers monos and cats in our club into the 70s with a Castle 2028, should be faster in a rigger with more aggressive props. This is an oval boat, not a SAW racer, you don't want or need extreme rpm.

I suspect that that at least some gas riggers and sport hydros (very similar in speed and handling) run in the 80s based on what I have seen at the Gas Worlds. My 4S rigger cuts 12 second laps and tops out in the high 70s on the oval. But FE boats have a very large advantage over gas - instant torque and acceleration. By the time a gas boat is half way down the straight the FE is starting the next turn.

fluid, I didnt consider running the castle 2028 on 10-s. sometimes i get one -sided. would you recommend the 2028 over the T.P. 5670?

Your running a cat. Try that same set up in a mono and see what happens.
I wonder how many of you have actually heat raced your electric boat in a gas race. Gas cats, sport hydros and riggers are running 70 to 80mph depending on the class of motor their running. The water gets very choppy from the big boats, and big boats don't handle as well in big chop during a race with small high rpm props. But that can be overcome with throttle management and that's fine for some. My boat was designed to blast down the choppy straits and that's going to suit me better.
But it's not the same as running your boat buy yourself and saying my boat is faster than them. That's easy to do.
I think the castle is probably better or close to the same as the TP 5670.I think the castles only downside is one KV choice. The TP 5860 and now 5870 are better for running bigger props and having more rpm choices. My 650 kv motor turns gas props in the 20 to 21,000 range. This will get me close to 75 mph by the end of the strait and that makes me plenty fast for heat racing. The gas guys turn the same props in the 17 to 18,000 range and are closer to 65 mph. If your not interested in heat racing against gas boats then RPM away and make a rocket.

I won open mono this year in district 19 with castle motor and 70mm prop.. max I ever saw speed in heat racing was 61 mph.. the only time I lost was to a twin rigger and that was close.. boat is close to 7mph faster with tp motor. And I only run 8s.. this is on a 45" delta force sniper.. handles rough water great.. also corners and out accelerates any gas oas boat

Mark, the cat and hydro do race with gas boats. Both won District 7 open classes this year and the hydro won the Voodoo open class. Ask Steve Lopez, he saw both at Voodoo a last month. Another friend is building an Insane G3 mono and using the Castle 2028 on 10s and he's testing with 6017-315 and a 6516 from Bob Austin. Also, I'm currently setting up a Hurricane mono and will either use a Castle 2028 or Lehner 3060.

I know how well your boat works Ray. I raced with you that one day. Your boat was a little faster than the monos I saw you running against, but you won that class because of how well you drive. Not because your boat was fast. I also watched Eds boat too and see what running smaller props can do to boat handling. But your a really good driver and you would make any boat look good. Wait till you see mine go. Talk about acceleration:) So how are you liking the TP motor so far?

That was my q in Vegas..my t mono is good.. haven't got to race it yet with tp motor.. but it is 7 mph faster than it was in same trim

which T.P. motor are you running? what is the weight of your boat? any video? thanks

[rayzerdesigns]

I'm running the 5860 970kv.. boat is a 45 inch delta force sniper.. weighs right at 20 pounds with 2 8s 6000 dinogy lipid.. only video I got was from friends phone.. not good quality.. and that was with the castle motor.. I will see if I can get some video this weekend test

[MarkF]

That extra KV sure woke the boat up. My boat must be 2lbs heavier running 10s.

whats better? 5860 650kv on 10-s. or 5860 970kv on 8-s.
