I'm sure this has probably been covered in numerous other threads, but after a few unsuccessful searches I figured I would risk asking it again.

I just purchased an RBC Huckebein and Wemotec Minifan 480.

I have read Bob P's thread on his Huckebein powered by a Model Motors MV 2020/20. (It's a beautiful plane Bob, and probably the catalyst for my deciding to build one.)

I am curious if there are any other suggestions in terms of the best motor and battery pack for this aircraft and fan combination. I know the MV 2020/20 is brushed. Are there any brushless motors that can provide even better performance or duration?

Any thoughts would be greatly appreciated.

Thanks!

Paul

Hi Tempest,

I also ordered the Huckebein, the Blohm&Voss and the Yak23 Flora from Rob Bulk.

I will try the KONTRONIK Fun 480-37 or the FUN 400-36 with 8-10 cells. First I will try some 1700 SANYO or later if possible the HR-4/5FAUP SANYO.

For 10cells you'll be best of with a motor with a kv=3500-4000. Using that you'll be able to use the fairly inexpensive 40A ESC's

My favourite 10cell combo is the Kontronik Fun400-36/Smile40-6-12 ESC. The Hacker B40-11S is very close in performance though its heavier than the fun400 series. (110g vs 125g)

Heiner mention the 480-37, if you're staying on 10cells max choose the 400-36 as its lighter and comfortable with the powerlevel (<420W) - and therefore better suited. However if you decide you want more power (450+W) the 480 series has an edge.

Get the HR4/5 1950mAh FAUP cells

Thanks Haldor and Heiner for the replies!

I was browsing the ICare site this evening with the intent of buying the 480-37. If I may run 10-12 cells, which controller should I purchase? I see that they also carry the BEAT controller in addition to the SMILE.

Any thoughts are well appreciated.

Regards!

Paul

Paul,

it is said, that the BEAT controller is better, if you are not going full throttle all the way.

Heiner

The Huckebein seems a rather light (and not very strong - as it's entirely made out of balsa) model. Go with a lighter setup, Hacker B40-11S or Kontronic Fun 400-36 or Mega ACn 16/15/2 or /3 on 8-12 (depending on winds) CP 1700 or CP 1300 or FAUP cells ...

The 480-37 will cope with 13-14cells and will be around 50A at that count. 10cells a 40A ESC is enough but at that count the 400-36 is better in terms of lightness and enough for the job.

I also have a Steve Neill ME P 1101 on order. Based on your collective suggestions in this posting, and Herb's posting in the ME P 1101 threads, it sounds like a 400-36 for the RBC Huckebein and a 480-37 for Steve Neill's Me P 1101 are the appropriate size motors to use.

I have not seen many references to AVEOX motors in these threads. Why is that? Are the KV's not high enough?

Thanks everyone for your help!

Paul

Tempest - for up to 400-450W the Fun400 range and hacker B40-S will do, above this you need the larger motor such as fun480 and Hacker B40L. In the <400W range a 40A ESC is sufficient.

Powerwise there is little difference between the 400-36 and 480-37, the diff is only that the 480 will take two more cells with ease.

For Steve's ME1101 I'd think the Fun480-42 or the Hacker B40L equivalent on 10CP1700's will haul butt, you'll need a 60A ESC though

Thanks Haldor!

For the higher amperage applications what controller would you suggest? In perusing Kontronik's product line the only BEC enabled controller I see at that amperage is the BEAT 70-6-12. Would you suggest using a non BEC controller?

Can I use other manufacturer's controllers (i.e. JETI)?

Thanks again and sorry about all of the questions.

Paul

My Huck fly well with B40 13s (3300kv) climbing at 60° without slowing down , very large loops,... for 4 minutes with 10 Rc1600.
So the fun 400-36 will do faster
A good choice!

Olivier

At 50+A draw most ESC mfgrs advice against BEC use.

Paul,

my FUN 400-36 and the FUN 480-37 are running fine with a BEAT 55 opto and also with the 70 A Jeti. But I would suggest use always opto controllers when drawing high A.



Heiner

Thanks Heiner!

What cell count are you running ?

Paul

Paul,

400-36 up to 10 cells, 480-37 up to 11 cells. It depends if I am using them in an EDF or just with prop.
