Twin powered carbon Rivercat build

[srislash]

I really like the look there Travis. Maybe make sure you have plenty of CG adjustment to deal with that fixed stinger setup.

Yea.....in this little hull I won't have much adjustment. I'm going to mount the motors first because I have no choice where they go, then I will mount the battery trays. Put batteries in. Then start laying out the rest of the stuff to set my Cg where my other rivercats were. I'll probably end up doing the Cg a tad further up because the twin props will likely give me more bow lift than a single prop. Then there is always a little ballast I can add. I'll do my best!

Really looking forward to what you think of the TP vs the Castle 1415

The tp did go a little faster but ran noticeably hotter. The tp went 64.5 and the castle went 61.8

How much of the carbon drive shaft "tube" is in the hull ? Do you think it would help to have a good amount of the carbon tube in the hull so that you can attach them and get a good bite of support for them?, Well besides the normal support under the rear overhang of the hull where the support point comes down and attaches to the shafts when it comes to the drives ? Im just wondering for myself because when i saw this i really liked the idea and would like to try and implement the idea of your drives "carbon tubes" and i would like to put them on my next build... But if that is alright with you first of all ? If you object i will understand but if your cool with me borrowing your idea that would be great. I look forward for your reply on my many questions i have asked ya lol

I have a little more than 1/2"'coming in the hull. Keep in mind that things are tight with this little hull and I'm running fairly large motors. Your welcome to do this if you like but I must warn you, it's a pita. It's hard keeping them lined up while the epoxy is drying. I had to jb weld the bearings in because the loctite sleeve retainer didn't hold them. Also put the bearings in last because I had to run a drill bit through the tubes because epoxy ran into the tubes (so it's a good thing the loctite didn't hold!!). I tacked one motor in place last night. I have had much time with it as I'm bouncing between 5 builds at once right now. I'll have to set my Cg once the motors are in place.

With those stingers you made, looks like moving your packs back and forth will be your only adjustment. Are your motors back far enough ? you might want to get those motors to the back as far as you can if you are putting your packs in the sponsons.
I hear ya about being a PITA... I built one of these out of spare parts and it is VERY useful installing bolts in these things. IMG_20150711_084536829.jpg

Man I have some awesome motor mounts. They are twist slotted. You loosen the screws a touch and twist motor and come right out. Easy.

I could not move the motor any further back because of the motor length and angle. Where it's at is as far back as I can get it. I'll figure it out. I have some ideas and I also know what the Cg needs to be on this hull.

I see what your saying. do you build the motor mounts ? i like the twist out mounts but not confident enough to make the slot and mount hole right.

I had Monojeff make them for me. I'll post a pic of the other. I have a template to trace if I ever need to. Once I get my cnc up and running (yea I still haven't fooled with it, been too busy) then I'll make a file for them.

That's how I roll...I'm not fighting with screws in that little space.

Guys, give me some ideas on how to support those drive tubes. I'm not crazy about just gluing some carbon plate to them and calling it a day.....

Thanks for the update

Are you familiar with "The force"?
