Hey willig,
I was looking for a decent size plane for my home area where I have a nice 55acre farm adjoining my property. The Flyzone Super Cub fit the bill. After reading all the threads & postings on several forums, I decided to do all my mods as I assembled it. I removed the cowl & motor & epoxied the inside of the fuse nose, especially around the steel motor mount. I removed the ESC & decided not to use the flimsy wire landing gear. I ordered a Turnigy Aerodrive DST 1200KV motor & Turnigy Plush 30A ESC from HK. Also got a couple APC 8 X 6E props. I fabricated an aluminum landing gear from an old "STOP" sign as it is tempered aluminum & flexes like a shock absorber. I used the 2 5/8" tires from my Sensei hoping for better grass handling w/takeoffs & landings. I added CF strips to the horiz. stab & made struts for strength.

When the new motor came in, the orig. motor mount plastic adapter fit the new motor perfectly with hole alignment. Installed the new ESC & a Spektrum AR400 Rx. A Zippy 3S/25C/1800mah battery fit in the battery bay easily. When it was all done & ready for maiden, I went to our club field where it is very open. The grass takeoff was almost a disaster as the field hadn't been cropped for a few days & the Sensei tires bogged down a bit. With a hand launch, the plane had plenty of power, climbed well, & only a couple of clicks of trim were needed. It flew nicely at half-throttle giving me 10min of flight w/3.74v residual left & 1125mah to recharge. I set my timer to 12min of cruising & used 1560mah.....all was well other than takeoffs/landings in grass. The following week, a trip to my LHS produced some great 4" foam "tundra" tires that did not change CG or flight characteristics & made grass takeoffs/landings a breeze. I managed to get 3S/2200 mah batteries to fit after removing the Velcro from them & now my cruising flight times are near 15min cruising. All is well now. Here's some pics...

Additional note: I had to reduce the rudder travel to 50% on my Tx as the rudder had excessive travel & now turns much better. Also, I used an E-Flight collet spinner to attach the prop.
