BBY MHz 44 mystic

[RandyatBBY]

I have a start of a build. It is a MHz 44 mystic with all German parts, the paint by Pro Painter and assembly by me. That is right even the hardware. I think the motors will be two 1950 5T I need a little help deciding what the Hi-amp or LK. I think the twin 1950 5T will be a hot setup on 6S. any way on to the boat as I received it.

That is sooo cool, I would go 2240/7 or 2250/5. Definetly go the LK

I like the choice I was thinking a bigger safer motor, I kind of liked the 1950/6 but the client wants a hot setup. That 2250/5 is hot safe power more or less (with a little care on prop choice and good ESC). Also I can have the 8MM shaft I want.

Got my eye on this one!

Very nice amazing work, one oder beautiful Mystic comes alive

[KillerDave]

F*****g wow!

[RandyatBBY]

It is going to get two 2250/5 on 6S should be real fast.

[RaceMechaniX]

Although they are in a twin the 2250/5 is in SAW territory on 6S. It will be very fast or very quick at cooking esc's. I was seeing 300+ A levels with that motor.

When you were running the 2250/5 at the SAW's were you running twins?

[nata2run]

There is always the option of 8s in wye mode. That should push some speed as well. If the boat is running very well, she should turn some 447's cut down on 6s no prob. Could be a 115-120mph setup. I think I will stick to 8s with 447 props at most. 100mph is fine.

[RandyatBBY]

Ithink this could be a good 4S single motor too, But this is a twin thread.

[nata2run]

5s with 447's or even PS 4516/3 could be real nice. If it was mine it would be on the shelf for display. Lol

[RandyatBBY]

If I painted it it would be on the shelf too. Just like my Smokin Joes.

[RaceMechaniX]

When you were running the 2250/5 at the SAW's were you running twins?

Nope just a single but I found out that a slightly too large diameter or pitch prop would send the current through the roof. Just have to be very careful with 50,000+ RPM.

Did you order the motors with 6 terminals or 3?

TG

[RandyatBBY]

I think we got the three terminals no need for two winds. You still have your motor?

[RaceMechaniX]

So you have the Delta wind which is 2367 loaded. One thing to remember is that Lehner rates their motors under load with timing at max efficiency. i.e. a Lehner 2300 kv is equivalent to 2650 Neu.

Yes, I still have my 2250/5 for a Q hydro SAW rigger.

Thanks Tyler I did not see anything about about delta winds or Y winds on the Lehener site. would the Kv be the same with a Y wind and it is the 6 terminals?

[RaceMechaniX]

You can now order the 19 and 22 series with options for 3 wires (Delta only) or 6 wires (choose between Delta and Wye) like the 30 series have had for years. A Wye would decrease the kv by the sqaure root of 3.

[RandyatBBY]

Thanks Tyler for the great information.

[RaceMechaniX]

No problem, that is an awesome motor you just have to be careful on props. Luckily there are lots of CR sets in the 40-45mm range to start with.

BTW, The 1950/5 is also an excellent choice for 6S. Not quite the power of the 22 series, but they are much easier on esc's and for a twin will still pack plenty of punch.

I am looking for a motor for my 34 inch War Eagle. The P Rigger motor is a little fast and races on the same day. but the hull is a little heavy and needs a lot of toque on 4S.

[RaceMechaniX]

The 1950 will probably not have the torque you are looking for. The 2250 will work. I ran this on 4S in P mono once and worked every bit as good as a 1521 1.5D with a smaller prop.

[RandyatBBY]

It is not real scientific but I look at the size and Kv and whether it is a D wind or a Y wind to pick my motors. It is more experience than anything else. I felt the 1950 was a little small too for the WE34.

On another note the motors and ESC for the MHz 44 mystic will be hear in a week or two.

[RandyatBBY]

Little up date the motors arrived. I am going to finish the boat I am working on then start on this.

It has been quite a week of work, I have been working on several boats. A little on each each day. This is the progress on the MHz 44 Mystic


I have a nice cover to protect the paint as I build.



Fitted the tubes to the struts holes.

I got the struts set up to mark and drill the horizontal stabilizers mountings.

On how many cells are you planning to run those 2250/5's, which ESC and prop are you considering?

I think he will start with 4S then go to 6S. Props in the 42MM to 45MM range. He has two MGM ESC's I think they are the bigger ones.

[RandyatBBY]

Gee back on this boat, I want to do nothing but it but I have so many fish in the friers and I need a nap. LOL
