T-Rex 500 Info

hmm, I think you'd be hard pressed to get a 5S2P 4200 as a brick on the top tray, I'll give it a go but I think some mods might be required. As a 3S & 2S one above, one below, no problem.

Reply..No Ash you misunderstand

My thinking is to recess the upper tray a bit lower down between the frame

Picture of the Thunder Power 5s 3300 in situ,fits nicely



Pack specs are 442grams 32x48x148mms

I am not suggesting you buy one,just gives a size comparison to a known pack

Does that actually fit under the canopy ???

[mattie-lodge]

That to me looks like what it needs. Something of that size and capacity

[ChrisB]

Does that actually fit under the canopy ???

Yes it does,,pic taken from www.jkheli.com one used in backyard vid


look at the photos on his front page,more closeups


In my opinion the testing is done,,buy a similar spec pack,whack the same 15 tooth pinion on and go and pretend to be able to fly like him

Revo do a 3300 of similar specs and size, as well as a 3200. Just for info.
The 3300 is 25C, the 3200 is 20C.

Awesome display Adie, Very impressed.

What packs and which pinion were you running there..

[robgt]

Nice flight!
What gear are you using on that (apart from 9650 cyclic servos )?

Cheers,

The revo 4200 2P is roughly 100x33X38 ea pack (two packs)...It depends on what orientation you want the battery to sit. Width wise 40mm is a tight sliding fit in the frames. A revo 4200 5S would have 10 cells. so about 63/64mm deep.

You could get 57mm if the cells were mounted at 90 deg between each other by using a 3S and 2S together but fitting the 2S in the opposite orientation. Whether this is practical when the pack is built I dont know.

The TP in JK 500 in the picture is 48mm high from the tray so 99% sure modding of the tray would be required.

There is no problem if you split the packs between the trays..but is it OK to run 2S/3S via a Y lead? cant really se it being a problem..

cheers

13 t gear and x2 3s 2200 25c packs you dont get very long on that sized pack but they are very good value for money at about £35 pound, £70 for x2 and you can use them in your 400 size helis

[Ashley Davis]

no issue with running 2S/3S on a Y lead.

What gyro are you using too - with what tail servo?
