need help with converting a hyper 7

[whitrzac]

I'm no newb when it comes to RC, but this is my first atempt at converting a 1/8 buggy, and I'm trying to do it cheap

my gear so far
tekin RS pro esc, with diffrent caps, and an external bec/rx pack
novak HV 4.5 motor
this motor mount
some misc. mg servo that I have laying around
true rc 5000 hardcase lipos/protek 4000 lipos/gp3300s


I only have the esc/batts as of now, but I'm seeing a problem on WTF to put the batts, I origanaly planned on haveing 1 pack on each side, but there too long to fit behind the diff, and too wide to fit on the side of it without riding up on the mudgaurd...

I still want to keep a "saddle" pack layout, but I have no clue on how to mount the batts.

I have basic tools to fab some parts up, but I would prefer somthing pre made


what kind of preformance/speed/gearing should I be looking at? it probably wont see any track time...

mabey somthing like this? http://cgi.ebay.com/NEW-SAVAGE-FLUX-...QQcmdZViewItem

would both of these fit on the chassis at once??

just an observation, why does a 32p pinion cost $4, but once its been drilled out to 5mm it costs $10-$15...

I did a dual pack Hyper7. Used the rcporoducts designs trays, at 125 bucks each I would say they were a waste of money. You can fit a pair of trays, mot the best way to run them though, for ft to rr balance.

I think the novak trays will fit fine and the price is right...

They are pricey and they are way too heavy. I would se the novak trays, or maybe cut down an old emaxx chassis, I did that a few times to fit my hardcase trakpower lipos.

FYI: Mike can make trays to any size. And even the custom option is cheaper than the Novak trays by a longshot...

Saddlepacks really aren't needed for balance. I find that the motor on one side and 6S A123 on the other works out just about perfect for me.

I never thaught about the e-maxx chassis....

the way its looking I'll be going with the novak trays


are there any hints you can give to make my converson less painfull?

what would be the recomended gearing?


also, I'v seen people runing a kyosho plastic spur, whats the advantage of doing that???

The conversion is pretty straight-forward... Just keep an eye on your signal wires, and try to keep them as neat as possible.

I like the plastic spurs as they are much quiter. And if you really stuff it hard, or land very poorly the plastic will give a little, or break, saving the motor... I would rather replace a 4 dollar spur than a motor. Mainly I use the due to the noise...

Recommended gearing is going to be difficult. I would almost suggest going to the 5.5 or 6.5 novak. The 4.5 is a high kv, and it may be difficult to get a small enough pinion to physically fit.

Your motor mount link does not work, what does it look like? How does it position the motor?

The novak trays are less than 30 for the pair... One of Mike's trays costs more than that? Unless i am looking at the wrong thing....

Oops, I thought you were referring to the trays that were $125...

Thats is what I figured. Those trays are nice in the idea of them, but are way too heavy, place the batts too far out and are just a bit too bulky. And they are super expensive!

I would definately suggest Mike's trays to anyone using a larger lipo, as they are sturdy and will offer better protection. I would personally cut down an old emaxx chassis, as he only needs to fit 2s hardcase packs.

^^^
the motor mount


I want to run saddle, not for the balance, but because I think it will work the best with this mount, and I only have 2s lipos for now

enless someone wants to trade strait up, the motor is set in stone, because at $40 I couldn't say no...(yes it has the 5mm shaft)


if I don't go with the kyosho spur, I can have anywere from a 46t through a 52t on it, I think I have a 46 on it now...


I don't think it could be much heavyer, the H7 stock wights 8lbs

[rootar]

id still recomend a pair of trays from mike, they would be the easiest to mount will clear your mudguards and come with straps and all the hard you need.

[whitrzac]

I would buy a set of the rcm ones, but enless someone has a used pair that there willing to sell, I only have enough $$$ for the novak ones :(

Hey, for 40 bucks you cannot go wrong!
