How fast can this go...

Picked up one of these - HK3226-1400

How fast can it be made to go? Without going too daft on ultra-high cost kit that is...

Thinking a new scratch build rather than mouldie, to keep costs under control, ala Ninja Speed style maybe?

Thoughts, comments, suggestions welcome...

I have a Friend that uses that same motor in a Sundowner 36 on 4s slightly clipped down 9 x 9 APC Electric Prop to 8.5 x 9. clocked at around 145mph and drawing just under 150Amps
I hope that helps

Hallo Rob,
For a Ninja-Speed sized Speeder i would take a bigger motor.
Erwin Schaumburger (the designer of the ninja) made some other interesting scratch built projekts as the 2/3 or 4/5 ( these Numbers are more or less the size compared to the Nina)

The 2/3 may be a little small for that Motor,its designed for Funjet-drives, but it may work when you keep airframe light.
I run my 2/3 with HK3026-1400 at 6S and 7x10 but will change to a lighter Drive soon.

http://www.rc-network.de/forum/showt...Funjet-Antrieb

The 4/5 was designed for up to 10S, Schiwo scored 380Km/h with a 3226-900 Kv at 10 S and 7x10.

http://www.rc-network.de/forum/showt...peeder-bis-10s

Your motor will not be able to take more than 6 Cells with reasonable props,so i would have a closer look at Erwins newest design,the Gixxer:

http://www.rc-network.de/forum/showt...ell-der-Gixxer

This Plane is designed arround 250g outrunners and 6 Cells,with your Motor, 6S 3000 and 7x10 i would expect speed arround 350Kph.

For all this planes it is possible to get Plan,CNC milled kit and wingcores.

Regards
Yello

203mph on 5s on a 7x10

Thanks Guys for the pointers and links.

I now have some research to do before fixing planform and size but The Gixxer looks good.

Good to see some numbers, I have 5S3600 and 6S3000 Lipos already in my OpusGTE, I'm scared to think what ESC I'll need with the 7x10 for this one

Cheers
Rob
