RE: Irvine .53 and 13 x 4 prop?
Flicking bak to the manual it says I can use 15% for contest flying so I'll still try it, nitro corrosion shouldnt be a prob since I run it dry after every session, Im hoping a tuned pipe, well a good one, will bump up revs nicely.
Thanks for the comments people! You saved me £5!
