Okay guys, I need a brushless motor for my HW 609 that's going into my FJ-3 Fury. I want to run about 12 cells either CP 1700's or RC 2400's both will be zapped. I bought a new Mega 22/20/2 for this plane without checking the amp draw( at the time I did not have Moto Calc) And its seems that MC predicts a 60 amp draw on 12 cells Not good for my cells or the motor. It will however produce 720+ watts Which is nice. I know that some of you have done some testing with this fan. I need any reccomendations that you can give me please for a good motor? I would like to keep my amps to 40 or so, I am going to run a Hacker Master 70-3P so I can go up too 16 cells. And I really would like to have at least 500+ watts. Here is a picture of the plane. It has a 37 inch wing and should weigh about 3 pounds all up on 12 RC 2400's.
Thanks for any tips or help
Joe

Hey Joe did you do any actual testing on your setup yet? I'm curious to see what actual amps comesout to be. Motocalc said my setup would run 50 amps on my setup but it actually runs 35 on 12 cells. And it was way off on the temp's

Barry, no I have not run the motor yet. I just thought that a predicted 61+ amps would be close enough to be dangerous. But I did email Ken of Megamotors and he told me to use the motor in the fan on 12-14 cells? So I will try it tomorrow and report back.


Steve, the stabs where not glued on in that picture yet. Don't worry I wont forget them/

or you can dowload the graphics under http://www.kontronik.com/HW609-FUN500-600.xls (rightclick and save under..)

I was just going over some data on Krontronik and some other sites, and I would test that setup for your self. Some of the numbers they wer at were pretty close to my setup as far as amp draw and they had lower draws with 609 so I know the pitch is less than Midi and we know the diameter is also. I'm curious to see where you end up with 12 cells.

Joe,

I have 2-609 fans with Hacker B50-12S motors running on 10 cells and they work great. I have been told that they will handle 12 cells but have never tried it.

Jim Phelps

Jim, can you tell me what type of numbers your getting with the B50-12s motors? How many amps do they draw on 10 cells? And what kind of watts are you getting from them? I am just curious? I have been told buy several people that My Mega 22/20/2 will run just fine in the fan on 12 cells. I will most likely run 12 zapped CP 1700's. I will try and run the motor tomorrow and see what I get?
Thanks Joe

Joe,

Take a look at a Lehner Basic 3100 or 4200 (rpm/V). The 19XX series motors would work, but the Basics are a great value at $129, and have a lot of power in a lightweight package.

Those Lehner motors seem pretty nice. There more money than Mega's but the performance seems a little better per application too. Gonna have to try these sometime. The 400-480 class seem like they could be really cool. And I'm still dying to see what you actually come up with for numbers Joe.

Have you tried any of these Dr Jet? Interesting to note that a single motor can be converted back and forth to delta or y wind!
Al

Al,

I have a Lehner Basic 5300 in a 6-cell hydroplane. I haven't put it in the water yet, but the word is it will outrun my 8-cell hydros!! The Basic series can not switch from Delta to Wye configurations like the other Lehners.

The Basics are the same size (and similar weight) as a car motor, yet are capable of nearly 700 watts output. These might be a winner in a 609 fan and a really light airframe.

Joe,

My Mig 17 has the following setup:
609 fan, B50-12S, 10-CP1700's, 48A, 465W, and about 28oz. thrust

I'm finishing another one and will probably try 11-12 cells in it. Amps will be up but I usually fly it at half throttle anyway.

I believe I read a post by Herb that he had a Mig 15 with the 609 fan, B50-12S, 14-CP1700's and 780W.

Yes indeed, it's in my red MiG-15, have been flying it for six months now. Jeti Master 70 A controller.

Herb and Jim. How many amps are you guys pulling on 14 cells? Moto Calc shows the B50-12S in the HW 609. Pulling 78.8 amps and making 1009 watts in That cant be right, I hope? Herb can you tell me what your amp draw is on 14 CP 1700's as that is what I would use? I sure would like the 780+ watts but not at that current draw. MC must obviously be way off in predicting this one? Please let me know guys.
Thanks Joe
