41" Delta Force Racing Build - Nitro to Electric

calculates to around 60mph but you will be carrying added weight in batteries as well which prob will affect speed a bit.

Would there be a better configuration of batteries to go with?

10 degrees is a good starting point.

Right on. So if I go with 4x Turnigy 4s 5000mah 40-50c. They should be enough power to get me in the 60s with a X457 right? That's in 8s2p configuration.

If its the Leopard 5692 - 1090 kv you have then its a y wind so 10 - 15 degrees.

I have it at 10 at the moment so that should be about right.

The 3 motor wires can be connected to any 3 of the esc motor wires, if it runs backwards swap any 2 over & it will run the correct way.

Ok thanks, I need to bench test it to see if the ESC functions correctly as there has been a few probs with the FC escs. Do you think the timing is right?

Hatch with final coat of paint done DSC_2354.jpgDSC_2355.jpg

Motor arrived.... flex cable and collet didn't

Motor Timing etc
Let me know if this is ok
I set timing at 10 and Khz at 8
Linear

Also since the connectors on the esc aren't colour coded what goes where? I have a Orange, yellow and blue wire on the motor.

thanks

Motor, flex cable, and collett will be here tomorrow!
I see there are some high quality overlander batteries going on ebay UK. Overlander Pro 60-80c but they are only 4400mah each so it would be 8800mah if paralleled. Is this enough mah for a 6min run?
Other than that there are some 5000mah 40c Turnigys I can buy on this forum but the difference in performance between the 2 would no doubt be really noticeable. Just comes down to run time...

Here's a link to the Overlander page. Price Is about the same as Thunder Power normally- http://www.overlander.co.uk/batterie...treme-pro.html

That's the transom mounts in.

[Drax21]

So I think I will start on a X457, see if the motor can handle it then upgrade to the X460 if it can. Motor placement will be as near the back as possible as I want power to prop.
Keep with the 2 blade props right?

[Drax21]

Hardware all mounted. The only holes I need to drill now are the water inlets. How's this look?

They work ok level but you get more drag than having them up a few mm.

I was just looking at my Cyberstorm and Ray Fuller has mounted the tabs completely flat with the bottom. On my DF41 I would say they are about 2mm up with only slight pressure on the tabs

[Drax21]

Also re the Osprey transome, its 300mm wide & the depth of the flat area ( bottom of v to where the deck join is ) 85mm deep. Overal from the bottom of the v to the actual top of deck its 100mm.

My bottom of vee to the top deck is 80mm but it is 300mm wide. I guess that's quite a bit of difference.
