Schumacher spirals and the moulded inserts

[jon kedge]

Just purchased from mb models some of the above for a couple of meetings on Telford astro,are the medium inserts that are from mb models ok,they seem a bit hard to go into silvers or do they stop the soft tyre from folding in the corners, the wheels have no air holes in them,any help much appreciated,jon

i ran hb red 1/8th inserts in silver mini spike were excellent

Thanks for that spud,will try to find out if they are hard,medium or soft,will try holes in the wheel to soften the feel and flatten the profile a bit.
