Hi there.

Can you give me a bit of info with regard to the throttling and mid range performance of the 26cc IFS petrol motor.
It's a toss up of either the MTW TD40 canister or the 3266 tuned pipe.

The motor will replace my problematic YS 140-sport and will be fitted to my X-TECH YAK - 54.
The model is 73" span and weighs almost 11lbs.

Would a 12oz tank be sufficient for a 10 to 12min flight, which is a mix of imac and a little 3d.

Prop wise either a Mejzlic 18 x 8 two blade or 16 x 11 three blade.
Oil wise, can I use 3W's own fully synthetic oil which is currently mixed at 50:1 for use in my 3W-55i powered WH Extra 300S.

Any info would be much appreciated in helping me to make a well informed purchase.

Regards

Aeroboy.
