1717 in a Desert Boy Chassis, It can be done !
 
Since I bought another 1717 I thought I squeeze my 1717 Heli version into my DB-17 chassis. Hope this well help you fellas wanting to do the same ?

The 1717 Heli version is needed unless you grind one side of the can flat ?

Use a dremel deburing bit to hog out the 3mm slots on a FLM or RCM Revo 3.3 Nitro conversion mount.

This is the gimmick I used and it made short work of the aluminum, a small round file will work but you'll be there a while.

I then cut a piece of 2" X 3" X 3/16" flat stock and drilled and tapped holes (4mm)for it to be mounted where the original Flux mount went on the motor plate.

I then eyeballed where I wanted the mount to be on the tapped plate for optimum gear choice (I can easily use a 10T pinion up to at least a 18T with the way I've done this) I counter sunk the holes that the hardware attaches the FLM/RCM mount to the plate.

Then once all together I placed the assembly on the Flux motor mount plate and eyeballed where I needed to trim the chassis to allow the FatBoy 1717. I didn't have to remove much, it took a little bit because I had to cut a little reinstall, cut a little etc etc. After I filed the cut edges I ran over the shiney alum w/a black sharpie.

The draw back to stuffing this pig in here is I have to relocate the servo from the original FLM servo plate and reinstall on the side of the chassis rail but I'm not comlaining.

Nice! I was hoping somebody would figure this out. I just wish the 1717 came at a higher kv. On 6s I dont think you can even reach 50mph with the highest gearing.

i hope we can see a video of this monster in action!

Bondonutz 09.26.2010 01:16 PM

I'm working on it as I write this post, I hope to have it all together today but I think I'm gonna swap out the RPMs for the stock arms and I have a pin wedged in the FLM bulk. Should be fun getting out ?

Video soon

You could use 10" diameter tires. :smile:

That's the motor mount the FLM FTC set has right? Are you saying it will fit without a problem?? I ordered a 1717, but the normal version because I thought it would never fit anyway ...

What is the diameter of the shaved side of the 1717 Heli?

EDIT: 46mm, it's on the site ...

It will. Just put a 25tooth pinion and install the high speed idler. I did the math. My db17 does 50mph with small racing truggy tires on 4s with the 20t pinion, high speed idler, and 2200kv motor.

Fast Lane Machine Bulkheads and HPI Anti Sway Bar kit
 
I had to do a bit of modding to get the sway kit to work w/the FLM bulks but it can be done with some patience and a 3mm drill&tap.

As you see I trimmed the front of the bulkhead down with a dremel wheel and hand file. I mocked the sway bar stay and marked holes, drilled and tapped.

Iwas able to use the little caps that are supposed to retain the upper arm pins, this took some modding also. I had to trim some plastic on 3 areas of the cap but it looks like It's supposed to after installation.

Just need to do the rear sway now, I hope this is the last of the stuff I have to do to this thing far as mods. Ben tinkering on and off for almost a week again and getting anxious to drive this thing. I also hope(I am somewhat confident) that the sways will aid the handleing quit a bit but we'll see I reckon ?

Doh, Just remembered I found some Proline 23mm 40series 1/2offsets that I have coming. I need to drill holes in the face of the velocity rims and then dye Black and install the tires. Not sure what I'm gonna use, probably the Losi ATX's. I know they are fairly common but they are a great tires for all around traction and durable. I may snipe them for more tread flex and better grip. I'll see how ambitous I am when they mounted ?

FLM really needs to update their machining for the Savage bulkheads so that it works with the introduced swaybar kit.

Have fun with the crappy 23mm ProLine hubs... I destroyed like 4 of them within a span of a couple weeks. Much rather stick with the 17mm standard hubs (or go with the 24mm HPI hubs).

Bondonutz 09.27.2010 05:59 PM

Not useing PatheticLine 23mm hubs, A company called American CNC Machine makes far superior 23mm hubs for most applications and they are usaully much cheaper.

For LST2/XXL applications the CEN stock 23mm hubs are the bomb, super cheap and they are steel.

These are for a REVO/Maxx but you get the idea

Nice work on the sway bar mount Bondo. Taking those ears off completely looks like it was definitely the trick - yours looks like it fits better than mine ended up. Now get this thing runnin!

Bondonutz 09.28.2010 08:16 AM

Thanks JT, I'm trying to get R done ! Ben strugggleing with finding time to do so.
