If you could measure yours I could compare it to my Rossi mk2. I may have an iron/steel set I could part with. Don't know your application but Cox cranks are all the same but they like to break if modified at all.

Thanks for getting back quickly. Check your e mail.

Gents: I currently have a Taipan .15 in need of a piston and liner set. As I understand that a Rossi Mark 2 piston and liner would work.
My question, if this is true, how may I obtain one. Is this an 'old' series that's far and few between or is it newer. Also, I understand that a Cox Conquest crank would fit. If this is the case, does it make any difference if it is a 'free flight' crank or an 'rc crank' model?

Any assistance or ideas would be greatly appreciated.

Had a phone discussion with Ron Young the other night. He was the engine test guy at Cox and was the one that suggested the tapered bore in the Conquest cranks to solve the breakage problem. He said that for awhile, the FF/CL engines had the tapered shaft bore, but the R/C did not. Eventually, management wised up and had all the cranks made with the tapered bore, to reduce tooling changes, and parts inventory problems. I didn't think to ask what sort of material they made the cranks from, darn it. But at least we know that you want the tapered shaft bore, and it can be either FF/CL or R/C derived. The K&B Conquest would be my choice...both ABC and the good crank.

I had one of those Taipan 2.5's, but only got 19k out of it on 80-20 on a FG 7x3.5 copy of the Cox prop. I ran a tap through the spraybar holes in the venturi and installed a K&B .40 2-pc spraybar. It ran very nicely, but not fast enough. Pretty little engine, all the more special after meeting Gordon Burford a couple of times.    Steve

Appreciate all the responses regarding the Taipan. I was aware that Mr. Young was the 'life blood' of the Conquest. I shall look toward a 'free flight' crank at least or making sure that the crank once located is tapered.
I'll touch base with the fellow in UK and see where that goes. Again thank you for everyone's input. This being my first interaction with stunt hanger has been pleasant experience. I have been lurking around here for a while checking all the information everyone possess,  definitely a major factor to keep things going with control line flying and other areas of the hobby.

       I am continually amazed at what the collected group knows, or has done. Basically just about anything you might want to know, someone here knows and maybe invented it.

better late than never . 

Dunno what the last one is / modern art . 

Theres a KYOSU , I think ( Have one , will check ) ABC that fits the ROSSI  , and thus by default / the TAIPAN .

The Kyosho 74016-05 piston and liner will not work in the Rossi 15 with out doing machine work to the piston. The wrist pin in the Kyosho piston is much smaller than the Rossi, which means making the wrist pin hole bigger in the piston to use the stock rod, or making a new rod and using the Kyosho wrist pin.
