23mm to 17mm

[baz2003uk]

hi i picked up a 2nd hand savge flux and it was fitted with 23mm wheel hex's
i have been looking around for some new wheels and tyres but seems like the better ones are 17mm fittings so looking at going to 17mm hex

first question
is there a downside to this as 17mm seems very popular

second question
i see hpi sell 17mm hex and 17mm adaptor hex kits (i have spare 17mm hex's)
what is the difference as the 17mm hex adaptors has a bigger nut
where as the 17mm hex sits behind the wheel and the use of the normal axle nut is used witch is allot smaller
that's how it looks anyway

third question
so i am looking at 17mm wheels
but going on the above (now this really sounds like i am thick lol) will the hole in the centre of the wheel be different sizes
as with the hex adaptor its allot larger than just the axle when using just the hex
if that is the case how do i tell what wheels will fit using the hex adaptor or just the axle nut

i would rather use the hex adaptor as the outer nut looks bigger and better than the little nut

fingers crossed i have sort of explained it well

Only reason i can imagine the truck has such large hex hubs is because flux is very powerful and it is possible youll strip the wheels hex pattern in the plastic with a smaller nut.

The difference is since its smaller than your 23mm hex its more prone to stripping out your future wheel hex pattern. The larger the nut is the less of a chance you have of stripping the wheel.

For instance my wheels i got for my savage actually use 14 mm and i was sort of nervous because thats really easy for my engine to strip the wheel pattern compared to my stock 17 mm ( mine is nitro )

I personally dont own a flux but I've seen them perform and its a very very strong truck.. I can't say i know this but i personally believe going to a smaller wheel nut will be easier for the motor to strip the wheels.

Question 1 : Larger = stronger but 17mm is pretty stout and as long as your wheels stay tight they should hold up well.

Question 2 & 3 : The 17mm wheels do have a larger hole through them. Using just a hex,you have to use a washer behind a stock nut to tighten the wheels down. The 17mm adapter kit makes the hub size match the wheel hole and has a larger thread on them which is why the nut is also larger. The adapter kit is the better way to go especially in a higher powered application,using just the hex leaves all of the forces on a narrower area and makes for a weaker set up.

I hope that explains what you needed to know
