hi all

havn't posted anything in this end of RCU before but i'll give it a go...

i've got a 33" correx deltawing that i got off ebay a few years ago with an MDS 25- the plane did't fly due to engine problems, so i upgreaded to an O.S 25 fx (with a 9x6) which was good. after the 25 Fx i had hopes of upgrading again by fitting a MVVS .28 with a mini pipe (swinging a 9x6 aswell) which i found was very poor.
The latest in engine selection for this model is an SuperTiger 51 which i have had hanging around for quite a wile - which i have just finshed squeezing in. i have hopes of the delta being ballistic with this motor and plan on running a 9x8,
However this prop selection i am not shure on and could really do with some advise on.
also, is there any easy or simple mods to perform on this engine to make it really scream ? i know a pipe would be a big improvment i don't have one available at the moment.
and also what fuel would everyone reccomend for speed ?

thanks all in advance of any replies
