My New TRF511

[djmcnz]

Well I've finished my TRF511 build and I must say it was a delight to put together compared to the 501X, so many less small shims, spacers and otherwise difficult parts to get your head and fingers around. I also learnt my lesson from the 501X and immediately discarded the standard screw set used a titanium replacement set so I won’t have to drill out any stuffed ones!

I’m using a LRP X12 8.5 and SPX Bullet Brushless Reverse and a low profile Bluebird digital servo. As you can see from the photos there’s a bit of space but watch out if you’ve got a large servo unless you have a small ESC or can somehow arrange things differently. The Rx is just a standard Sanwa 2.4 FHSS unit.

The LiPo’s fit in just fine with 2mm spacers under the standard posts. They fit between the posts and clear everything except the centre bulkheads. I got around this by shaving about 0.4mm of the LiPo case down in one corner – hardly even breaks the patterned cover so no risk of exposure. All said and done I’ve still ordered some of Fredrik’s LiPo cradles – they will remove any risk of lateral movement and I feel easily moving the weight back a bit might be a nice tuning option anyway.

Robinson Racing hard steel pinion against an Associated 87T spur gets the power to the belts and standard diffs with 10 ceramic balls each get that power to the wheels.

I’ve added the 501X aluminium steering setup and stiffener, perhaps a little more for the bling factor than anything else. I think the stiffener actually completes the look of the bulkhead assembly.

Here are some photos before the soldering. I wish I could take good pics.











Pinion/Spur mesh, not 100% but good enough.

Hope to enjoy it soon!

black those wires out though

Out of interest, is that the best way to do the motor wires? I'm finishing my 511 off at the moment and was going to wire it how the TRF drivers had theirs for the euros going through the centre bulkhead and over the belt

Very nice.

I put the wires over the center bulkheads. It was the easiest way.
The only thing you might want to avoid is to put it through the drive belt. Makes it more difficult to change drive belt (if necessary).

With the diff cover you ordered you will save both belts and pulleys.
I don´t have a scratch on my drive belts.

Only option you need now is the new ball cups. Probably the cheapest and most important option.

Put a drop of oil in the motor bearings regularly. Maybe after every 8 battery pack. Maybe you already knew that.

What screw kit did you use?

I have not had any issue with my 501X screws but I think you just need to use good tools and make sure they are properly seated in the screw. All good so far with mine but having just said that I can see me now stripping them hence the question.

Also where did you get the blue spacers or were they spare in the kit?

It's a lovely car, what are your planse for the body shell?

Thanks
