And for this one , check EBAY ... they sell all the time for around $10.00 , almost 1/3 the price .

And if you want to change this one ( that engine is BIG , which ALSO means MORE fuel sucking ... LOTS more fuel sucking ... )
Instead of your choice , how about this one .... ringed too

and for the this next one - ABSOLUTELY NOT ! ! ! ! ! NO WOODEN PROPS , EVER ! ! ! !

Go with nylon , glass filled , plastic , whatever you want to call them , just NOT WOOD ! ! !
And for plugs , you can get ANY one that is cheaper .... they are almost all alike ( except temp range and length and some have idler bars on them and so don't ... personally , I prefer the ones that don't )
Also , I see you chose an AIRTRONICs servo ... for a FUTABA setup ? Go with either HITEC or FUTABA or GWS servos .... NOT Airtronics ,.
