Default RE: Ultimate biplane, mid-sized arf.?

There is a new one graupner ultimate 1400 mm or 55 inch similar to seagull or Goldberg sitting in LHS with that santa christmas buy me look

https://shop.graupner.de/webuerp/servlet/AI?ARTN=9577

I particaly want to go with a MVVS 26cc 160 2 stroke glow preferably with tuned pipe as the club tow planes 10 year old one is still going stong and never gives problems even after three major crashes starts first flick every time using zero nitro and easy to tune and on half power dont use so much fuel as zero nitro gives you nearly double the range than 15% nitro and MVVS with tuned pipe and its high compresion is probably the same power as 160 OS with 15% nitro

Also with a shallow pitch biggest prop mayby even three blade so that as I come down from vertical dives I can get the slow down affect and when I use for hover it will hang with plenty punch out


Also for learning the basics of acro pattern shedule before going for mono wing

Also more easy compact to take on holidays on airliners and for small jap car I use

Also as back up extra tug for gliders for the club with reseve power

Going through the thread seeing its seems possible to use 180 on 55 inch gives me hope its possible

Realy I trust the largest glows a lot more than the smaller glows so its find the plane that fits this motor not the other way around
In all my other planes up to 90 size it electric for the last few years but but the cut off point for various reasons like draging around 2.5kw generator and stock investments in LIPO companies in the sky etc makes glow zero nitro at 160 size with tuned pipe reliivly so cheapand reliable and easy it glow in that size and non of the power losses from gasoline

I was also hoping that greneraly using motor at 1/4 to 3/4 gas the engine noise would be reduced using larger props as being eletric type hate unnessary excessive noise (and rarely using full power except for towing to get out of trouble )

Any ideas its a real bad idea chime in before I commit in Christmas for plane and January 2008 for motor
there is a Rodel cap RTC 2metre but I would prefer to do that next year with another MVVS 160
