ORIGINAL: Stryker_Viking I helped a guy the other week at the field with a similar setup as yours, this is what I had to do to make his Stryker balance correctly: * Removed all duct tape in front of COG-dimples * Replaced the frontwheel with a Light-Weight alternative that I had laying around * Replaced his stock 6x4 prop to a 5.5 x 5.5 He later used spray paint to the areas where the very heavy duct tape had been... Good luck Stryker Viking thanks Stryker Viking, What happened to your friend's plane did he even have the guts to maiden it.. if so, what was the result? My big question to you is about nose-heavy planes. I heard that if you fly nose heavy its no problem. if you fly tail heavy, you fly once. So given that my Stryker is nose heavy (assuming that carving out the foam in certain places did not mess up the center of gravity of the plane at the COG dimples), will this present a problem or what? I might remove the duck tape because i am positive that it adds a lot of unnecessary weight to my plane, although removal probably won't affect medial balance (nose-tail heaviness). Do you think the clear transparent duck tape i covered the rest of my plane with adds too much weight as well? it is the duck brand packaging tape and i have it all over the place on my Stryker. (Only a single layer) If I remove the heavier duct tape along the middle of my Styker, should I replace it with clear transparent packaging tape like the rest of my plane or can i use strapping tape which is heavier. I just wanted to make my Stryker strong in case i crash it hence the duct tape. Last question is about the 5.5 X 5.5 prop. So it is shorter than the stock 6 X 4 prop but has greater pitch. How does the 5.5 X 5.5 prop compare to a 6 X 5.5 prop? Just curious, and do you think i can upgrade to 6 X 5.5 with no problem. *just for clarification as it gets confusing: duck tape = clear packaging tape by duck brand, which i used everywhere on my plane except where I used duct tape duct tape = colorful, heavier duty tape also by duck brand, which i placed on middle of plane on its underside. ... Thank you everyone. iamman711 You are right on the spot regarding nose-heavy vs. tail-heavy. A tail-heavy plane will behave like a wild bronco, been there/done that once - and that's enough. Nose heavy is ok inder the assumption that you can launch the plane safely (I use a bungee launcher) My Strykers are always nose-heavy, about 0.5-1.0"... this also fit better to my flying style with much less deflection on the control surfaces then most of you guys are using, I like the plane to fly more jet-like with wider turns that doesn't take down the airspeed... Regarding your tape question: We are a couple of guys who at least in the beginning covered the whole airframe with strapping tape to enhance rigity, originally 3M-Extreme was used but I have found that it's bi-directional propertys add unneccesary weight and have shifted to uni directional strapping tape used in a more intelligent way and only where needed, saves a lot of weight... I wouldn't change anything if I was you, perhaps investigate lighter materials for next build... 5.5 X 5.5 prop vs. 6 x 4 prop: In this case we achieved higher rpm, but the purpose was to get ground clearance... Upgrade to 6 X 5.5 without problem: I am not sure what motor and battery-ESC combination you are using, would doubt if it's C-stock version, perhaps someone else know more about that motor...
