I got the 600 cc hirobo fuel tank for my xspec and running a 91 OS PS.
Should I also run a header tank?. What do you guys think?

Has anyone bought the quick UK metal swash? I think my stock plastic one has play and is brand new!! I like the thought of being able to adjust out play and I don't want to hammer the cage!

I'm currently running the 550cc tank and twin header tanks for duration - a 2oz and a 6oz. I've got the 600cc tank in stock and will be installing it in order to remove the need for the 6oz tank - but keep the small header tank.

Indeed, that;'s the one. I just used some beefy elastic bans (3 of them) around both header tanks. It works fine, but you need to change the bands quite often since the fuel eats them up. Its not pretty, but it works.

I've had one of the 2oz tank brackets split on another machine, I copied this idea off J2M who uses some carbon fibre sheeting to create a more robust mounting bracket.

There is nothing bad in header tank...but I think the way you do is actually toooo much!

I was only getting about 9 mins flying time with the new OS91 PS, which is why I added more capacity. Now the engine is running in its not so bad, but about 14-15 mins.

Sorry for off topic, but
Dr Lodge, how do you find your new engine, was it good or you got any troubles?

thanks guys
I appreciate the answers. I'll get the quick uk swash. I bought the hirobo stabilizer bling parts which are nice and the cross bars between the old plastic ones are the same part number so I'll just use those. I didn't really like the plastic ones as when i did the screws up the plastic bits were twisting. I also bought the hirobo ex tail rotor servo mount. I'm gonna get that quick UK third bearing block for the tail rotor. I think I'll stick with the plastic grips.
The header tank will go on. I am thinking about a third needle for the OS PS 91. anyone done that?? I'm also going to do an onboard mixture set up. What do you reckon the best and lightest servo will be that could handle the vibes? It would need to be digital and very accurate also.
Cheers

So far I like it - gobs of power, very smooth. I've not had lean mid range problems but I'm using the HT700 pipe, not an MPII, also on 5% nitro only. In fact its a tad lean around idle so it tends to "hang" a little on autos.

Going even more off topic...I may try the 970 pipe. Initial trials on an SX-H shows this pipe with 15% to be more powerful than an MPII on 30%.

Oh, and I've got a length of garden wire holding the perry pump in place. OS must have had a brain fart if they thought an oily O-ring and a short length of tubing would hold this in place

Sorry, sorry for off topic...
Hm...Dr Lodge...you know all these 3D champions with 91PS everywhere simply make my sick...actually I was thinking about YSor O.S., but the fact that too many people got something about 91PS, are pushing me to think once again...

Would you buy PS now if you get a chance to turn back time?

Its a tuned pipe not a muffler... http://www.skylinemodels.co.uk/acatalog/hat970-2.jpg

Yes, I would buy a 91PS again, but would seal in the pump rather better while its new and clean
