TRF511 Lipo cradle
 
Iīve 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:thumbsup:.
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 18-08-2009 07:34 PM

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 18-08-2009 08:54 PM

Thank you. Iīm glad you like them.

There is a cradle for the 501X on itīs 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.:thumbsup:

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

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 12-03-2010 08:44 AM

My own design.

Want some?;)

MHeadling 12-03-2010 08:47 AM

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 16-03-2010 09:48 PM

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! :thumbsup:

Fredrik Emilsson 17-03-2010 11:12 PM

Glad to hear that you liked the parts.:)

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

Mouton 03-04-2010 08:41 PM

Plus one for a great design!
 
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.

Iīve 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.

[QUOTE=Fredrik Emilsson;463927]Iīve made a new lipo tray for the TRF511.

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

Fredrik Emilsson 15-02-2011 09:50 AM

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 canīt 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.

marco NL 15-02-2011 06:11 PM

Great job Fredrik:thumbsup::thumbsup:

mattybucks 16-02-2011 08:15 PM

Any price yet Fred?

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