Canadair CL-415 build


       Remove this ad - become a site supporter!
I had this ARF for a while and it is now time to assemble the thing. I am planning on converting this to electric. Although I generally prefer glow, I think that the reliability of electric will be a desirable feature considering it is a twin and it is a flying boat.

I bought a pair of Aeolian 4260 600kv that I will try to match to scale four blades propelers from FMS. Those props are from the 1400mm FMS P-47. The biggest challenge will be to make the prop hub fit into the 2" spinner and I will have to modify the way the spinner cone is attached to the backplate.

If that all work good, I might consider adding scale retractable gears in the future...

Re: Canadair CL-415 build

A 42-60-600 will burn up trying to spin those FMS 4-blade props!

I don't know if you checked the specs of those prop or if you are making an informed guess but the stock motor on those FMS plane is a 4250 540kv witch is slightly smaller than my 4260 and the kv is similar...

It all come down now to how many cell this is going to be run with

Re: Canadair CL-415 build

I have significant experience with the FMS products, they changed motors on the 1400 mm series for a reason! I ran Aeolian 4260-520 with MA 14*8*3 on 5s packs and got perfect performance. My FMS 1400mm corsair ran on the old motor, 4 blade stock prop, 4 cell pack and I was lucky to get 4 minutes. Changed to a kv closer to 400 and flight time changed significantly to 7 minutes easily, all scale flying.

However, if you have all the parts you might as well go ahead and get the experience, you will eventually figure it out.

Re: Canadair CL-415 build

Well thanks for the info but like you said, now that I have it all, I might as well give it a try. Fortunately, I got a really good deal on the Aeolian and if I cook them, I hope they are going to make a good smoke show

Question about the Aeolian, are they any good or just a piece of Chinese cr_p ?

I was actually considering something around a 5045 500kv initially but was concerned that it might not fit inside the cowlings. Also not planning to use more than 4s as I already got the batteries and I'm not looking for performance here as long as it fly. Really, it's just for look

Re: Canadair CL-415 build

Those props can suck up a lot of power, direct drive is not the way to go. I would suggest a setup with a reduction drive. A fast turning smaller motor will consume less power. I would pitch the prop to give 40 MPH at 10,000 RPM and get a motor and reduction drive unit that will give this.

Although this might sound like a reasonable idea there are a few problems with reduction drives. First it add to the complexity witch is not desirable, there is also the problem of fitting everything inside the cowling and finally I have no clue where I could find such a thing not mentioning that it would have to be the right size with the proper motor.

And again, I could not care less about ultimate efficiency of the thing, as long as it kindda works I'll be happy

Re: Canadair CL-415 build

I have same aircraft Alain and am looking for a power package. same as you - as long as it flies well. I found an outfir called Value Hobby in Illinois and am checking if they ship to Canada. Looks interesting but I will buy locally if I can.
