I would drop down to a 9x7 (APC) You need more Pitch and Less Diameter to go fast.

You might consider a 10x6 first just to make sure you have enough OOMPH for the launch... but 9x8 is where you should be headed for speed---

Keep us posted!

11/6 does nothing except for trainers, try those other recommendations How much does that thing weigh?

Hard to say really what speed, it was just as fast as my Delta with a 46FX upfront............ ive changed the prop to a 10 x 6 soo just waiting on some good weather to give it another go

Ive also added some illuminus orange on the bottom of the wing, as its just dark grey so hard to see in the dull english weather

Did you fly this Tigershark again ? Weather is just fine now !

I am preparing mine for the maiden ! A NIB webra .50gt will be there to power this lady ... I also have a Macs full (noisy) pipe on order . It will be a nice 'addon' over the ugly stock muffler (not the pre-tuned one [:'(]) for more speed.
I'll try to tape her.

Hi,

Yes i did fly her again, but due to a deadstick it was a very short flight and hit the only small bump in the field when landing and broke the nose off .......... so its on the building board just waiting for a repair which shouldnt be too much problem.....
