BMV Torsion (TLT Axles) Reborn w/DIG etc

[sweli]

Purchased a used BMV TLT on here as my first rig, 16mo ago.
11" WB, Stock axles with a B4/T4 trans and pede shafts and wheels.

Few updates through last summer, but reached a point this month to have her reborn rather then rewarmed.

• New Piano wire, taking the WB to 12"
• R2DII Enclosed Trans
• Custom Delrin DIG Servo & ESC tray on top of R2
• Used RC4WD wheels w/ 5.6" Rock-Claws
• Hobbico CS-80, 1/4Scale Servo w/330+ oz
• Revo Shaft Frt, Venom CV shaft Rr (temp.)
• MIP CVs all around, Straight adapters Rr, Alum Knuckles Frt
• Clocked Rear Axle
• Novak Rooster Crawler into an AstroFlite 15T cobalt
• 6+1 Saddle behind frt axle on top of custom black PC skid
• CC BEC at 6v
• Novak Xxtra Synth Rx inside a RatShack box w/window and tune holes
• Miles of Wire Loom

Delrin DIG Servo and ESC tray





Mounted on top of R2. Short Linkage on left side to DIG.
ESC on top, in relief cut, with hold down bone.

New Skid, mounted on Piano wire.
Riser block on left is into skid and R2 w/3mm flatheads, then Servo/ESC tray into the riser block.

Side, slightly high COG huh...... LOL



Back/Bottom of Frt Axle -
1/8" PC Guard starts as a skid in the front and continues under axle and folds upward to hold 3+3 saddle pack of 2/3A cells tucked behind the axle case. 7th cell is in line before the Deans plug, and is velcro'd to the back of the g-i-n-o-r-mous servo.


Novak Xxtra Syth Rx inside a Ratshack box over rear axle.
Antenna laced through 6mm Twinwall PC (thin greenhouse roof material).




Test her out this weekend if the weather holds.
In west Mich we have to drive to the rocks. Toooo much sand!

hey very nice rig like the dig mount, i have somethin like this and was just wondering whats the width from wire to wire? Thanks for the help

[sweli]

Wire spread is 58mm (2-1/4"). It is 1/8" Piano Wire.
I bought new wire to lengthen this from 11 to 12". It is stiffer now then it was at 11"(??). Either the grade of wire on the stock chassis was better, or it was just broken in.

I put a very slight flat on the wire, where the four end plate collar set screws seat on them, and Locktite blued the set screws. Before that I had them come loose various times.

xEL, do you have a pic of your rig posted?

I tried some MOA Cliff Climber axles I had with smaller dia wire set closer together, thinking more flex.
I got the flex alright, it would twist 180deg. and amplified the clod stall of the rear axle.

I like running at GTG with sprung and droop axials and missing places they go, but going places they don't.
Def not a comp rig, but fun.

Clocked rear axle. Trapezoidal delrin blocks and nylon spacers hold the axle at a the right angle so the rear drive shaft yoke is almost at a neutral angle.




Currently I am running an old beatup Crowd Pleaser body that came pre-painted. Two posts over rear axle hold the body secure, while it is allowed to slide and angle over the single larger front body post, above the servo. If it was secured at the front, the whole body would act as part of the chassis, limiting flex.

Anyone else have a BMV that wants to chime in?

I dont have any pics of my rig up here, its not a BMV just a home made getto crawler lol. and wow mine is way wider than yours.. maybe its time to chop it up. Nice build though!

[sweli]

I have the RCP wide hexes on the front, narrow on the back.
The narrow track, large tires and high COG make it not side hill well, but I like snaking through tight spots that some AX10's I run with, won't.

I have considered trying some 1/2 - 1" wideners. Might yet.

Thx for the build comment!

Wow that looks great. I have a BMV II that I am contemplating building. How do you like this rig?

Lastnight, some crawling between my BMV and 1.9scaler.

Not bad flex for a piano wire BMV chassis.
