feigao motor question

[saleens7]

can the feigao 14XL hande voltages up to 29.6 volts? if i go lipo, thats how many volts ill be getting....the quantam motor i have have acutally "blown up" on 24 cells (someone on another forum tested it on 24 cells, and it happened to them)

Check out the end of the "conversion" thread.

What prop did you use with the other motor?

[saleens7]

i didnt blow it up, someone was testing it on another forum and it blew up on them....i dont know what prop they used...i think they said it was a plane prop and they were bench testing it...

[saleens7]

i checked the "conversion" thread, but that doesent help me....

Do your self a favor...buy a feigao and unload that quantam while you can still get somthing for it. IMO your hull is way to big to for that motor to push and now you are intraducing lipos into the equasion. I have a feeling you are in for issues with that motor.

issues with the quantam or feigao? since i figured ill need 24 cells, (and now lipos) i am having serious doubts with this quantam.....its a good airplance engine, it will turn a big prop with a lot of tourque...maybe ill give it to someone who would use it for that...

i would have used a larger lehner....but the prices for that are kind of over the top for me.....

hate to jump in but on the feigo, what is the highest voltage you can put to a 10xl?

[SJFE]

To elaborate...I beleive the quantam is a lower quality motor. IMO I don't think it will hold up. I have no proven data to suport my opinion. I am just a firm believer in " you get what you pay for".

I have run 19.2 volts through my 12XL for 7.5 minutes WOT 80% of the time on a 45mm prop. Temps where 85 to 95 degrees.
I would say the 10 will handle that. The kvm ratings are not that far apart.

I have run 18 cells (21.6volts) on the 10XL. Ray Fuller said not to push more than a 5lb boat with it on direct drive.

[saleens7]

sounds good, ill be using the14XL so the lower KV will mean it can hold up to more weight to push, right?

[Mich. Maniac]

well I am running twin motors on a oh id say 6lb boat I hope I can run 18.5 lipos with octura 447s and be extremely fast! everything liquid cooled with its own intake and outlet

[part time]

the feigaos are50000 rpms max. pick a kv that will come in under that at 28.8v and u should be fine.

[Mich. Maniac]

well, if the 2 10xl's will push the boat without problem, and i run the 18.5v supposedly with a calculator i found this boat will be above 100mph minus drag from rudder and hull. I dont think it will do it but I guess we'll see. Hope for the best and expect the worst!

Here is a video link to a 42" cat running two Fiegao 10XL's.

That is is perfect handling boat. what kinda speed is that if you know?

[ReddyWatts]

It runs in the 40's.
