Attn Pagemaster and Jeff Wohlt

I am interested in a dual motor/dual drive setup as well

Pagemaster, on your website I see that you said thanks to Jeff you have a 700 that will go in reverse. I also see that Jeff has posted that the Graupner 7307 is available in reverse.

I did find this motor in the Graupner catalog. Speed 700 Turbo C 9.6 V. Now it lists an RPM of 14600.

Now my question is: For my villain (don't laugh its a fun boat) would two of these motors be faster than two 05 car motors which seem to run higher RPMs at 15 turns or so??

And pagemaster...even though your project is OBs, I'm still very interested...keep us posted!

you would have to put on bigger gears... because the can is taller and woulnt go down all the way for the stock gears to mesh... and you would have to grea it up.. like 1.5:1 or even 1:1 with smaller props... but then w/ two 700's you are going to have to carry atleast 24 cells so there is the weight issue... as for which is faster im thinking it's kind of a draw!

Rob which 05 motors are you comparing it to. The main reason for me using the 700's is maintenance. Two hot d4's would be faster then 2 stock 700's on 12 cells, but 05 need to be rebuilt often, 700's don't.

I am planning to run 2 -14cell packs in parallel to keep the 6 plus minute run times. I decided also to get Neo motors and take one apart to reverse the endbell to make in run in reverse.

Rob,

If memory serves me the 05's in the Villian only get power from 6 cells each. The 700 motors need voltage from 12 cells each to work well. You still could run a pair of them with your two 6cell packs wired in series and your motors parallel but you'd have short run times. Or you could put two 12 cell packs in there but with two 700's and 24 cells it probably wont float. You might be better served to gut it and put one 700 direct drive. You should check out the Villian transformation on Lou's web site. You don't have to go as crazy as he did to get the idea. A single direct drive 700 would probably be faster than your geared 05's. The 700 can turn a bigger prop without the gears. Your 05's can spin like crazy but have to be geared to turn props large enough to push that hull. Check out Lou's site. I think he tried everything shy of throwing it away and starting over.

I still think the Villian is cool too.

Hey guys...thanks for the replys...sorry I wasn't more specific.

I'm stuck on keeping twin drives/twin motors. I think they are neat and I like the challenge. It's different. I know everyone will suggest one drive line which is smart...but i'm weird like that.

Yes I was comparing it to the trinity 15t double p94's. I like the idea of not having so much maintenance.

I am aware of the mods needed (i.e. turbo tranny, new esc). I also plan on replacing the steerable drives with the octura flex drives.

I wasn't planning on using 24 cells....just 12 and therefore split the runtime in half...which is ok with me b/c I just screw around with my boat and jump waves...thats what is fun to me

Pagemaster: how hard is it to convert the neo 775 to reverse??
Could this be done with an SS1 as well?? I will keep tuned to your project but I must say all those cells and motors....wow! heavy boat.

Thanks again

I am experimenting with it. I will take notes and picture to make a step by step web page if it works!

Rob,

Have you seen the dual drive strut bracket that Avenger came up with? That might be just the ticket for dual octura struts. Pretty cool idea.

I thought the 700 was just a glorified drill motor. If that's true it would have neutral timing. I would think you could just wire it backwards. It can't be that simple.

Why not run 2 graupner 6311's instead they are 16 turn speed 600's 7.2v Same mounting pattern way more durable than 05 and you could run them from 12 to 14 cells with motors in series.

If you are sure you are staying with the stock set up then you need some timeable motors so you can swap one endbell.

I would run the motors in para and stay around 16-18. It will be fast alright. Find some DOubles but I would not go with triples. You need as much torque as you can get.

The gears are the key. Stay with 12 cells and a good low gear ratio around 2:1 and then spin the R&L Octura props 447 I think....sharp and balanced well !

Graupner also makes a 650 motor that his hot with timing but have not seen one.

[Randy Naylor]

If you used two gear drives and turned one around and have the out put come out the other end would not that reverse the drive?

All great ideas fellas. I think I will just wait for pagemaster to comlete his little neo 775 project and learn from him. I'm sure two of those would get this thing cooking
