TRF511 Lipo cradle

[Fredrik Emilsson]

I´ve designed a lipo cradle for the TRF511.
With the cradle the lipos are moved back to clear the center bulkhead. It is secured with 2 screw. The front screw is using the same hole as the original battery post. The rear screw uses the same hole as the undertray. So no need to modify the chassis. I also use the original battery posts and battery plates. The cradle is 69x47mm, so most saddle pack lipos fit. Will be available in plastic and carbon fibre.

Simple and genius.
Rather do that than the grinding operation the Tamiya team did on their cars. Lucky for me we live in the same city. No problems for you to ship them though.

Does this cradle by any chance fit the 501x as well?

[jhammond]

I would also like to know if your cradle would fit the 501x; I was under the impression that the 511x had the cells moved slightly forward?

Fredrik, I'm also interested in the 501x diff covers, have you any more information on price and shipping costs? I have to say your creations are absolutely stellar.


Regards,

Julius.

[Fredrik Emilsson]

Thank you. I´m glad you like them.

There is a cradle for the 501X on it´s way too. Will post pictures of it in the next couple of days.
The main difference it that it only has 2 holes. You attach it with the battery posts. Very simple.
The diff cover for the 501X is also available.

Will update that thread tomorrow with fresh pics of the final cover and price. Will cost approx $45. Not the cheapest, but it will save you a lot of maintenance and belts/pulleys.

Tomorrow I will hopefully have a price on the lipo cradles as well. Should be approx $20-$25. That´s a more "normal" price.

Very nice designs Fredrik!

[Fredrik Emilsson]

Thank you.

511 LiPo tray also back in stock. Slightly redesigned with a "slimmer" look.

What battery straps are those? The reason I ask is I need some as my car only has 1x tamiya carbon straps and they are pretty hard to get hold of

[Fredrik Emilsson]

My own design.

Want some?

[MHeadling]

Yes please! Work me out a price for the straps and 501 cradle and we will sort it out later on via PM.

Thanks for the help!

[MHeadling]

I got my battery straps and carbon lipo locators today in the post, they look great quality and fast shipping too!

I'll fit them tomorrow and race with them tom night!

Highly recommended!

[Fredrik Emilsson]

Glad to hear that you liked the parts.

My new homemade lipo cradle!! Lipo can fitting without filed the bulkhead! (Do them like Fredriks)

[Mouton]

I have Fredrik's LiPo cradle on my 511. Even the taller IP 5 200 mAh 45 C LiPos fit perfectly. You only need to add a few millimetres of washers on the battery post screws. There is no need to file anything.

Great design!

Off Topic:
I look forward to tear down the differentials after a few runs on our dirt track! The car also has Fredrik's front and rear diff covers.

I´ve made a new lipo tray for the TRF511.

With the tray the lipos are moved back to clear the center bulkhead, just like the previous tray.
Carbon frames are secured with 2 screw. The front screw is using the same hole as the original battery post. The rear screw uses the same hole as the undertray. So no need to modify the chassis.
I also use the original battery posts. The cradle is 69x47mm, so most saddle pack lipos fit.

Center piece features 2 stainless steel weights. They weigh 17 and 27 grams. They are attached with the pre-drilled hole.

Each weight has 3 threaded holes and 1 slot. Holes allow you to adjust position and slot to add second weight without removing the first weight. Just slide it in under the first one.

Looks good Fred, do you have a price, and are you taking orders?

[Fredrik Emilsson]

Thanks!

Will add price later today. Expect to have all parts ready within 3 weeks.
Stainless steel parts are already in stock.

One thing I will add is the option to use shorter centerweights, as these long ones can´t be used with the long diff cover.

You will be able to buy the each weight separately, so if you want 2x17g or 2x27g for example, thats ok.

Great job Fredrik

[mattybucks]

Any price yet Fred?

Does the tray move the cell further out from underneath the bulkhead?
