[N777XS]

I was just wondering if a Thunder Tiger 42 work alright on my spad3d?

Check out the amendmets for the 40 size (standard is 46), the TT42 will be planty OK

N777XS - what would be the all up weight of your spa3d with the gp42 installed?
Woodsy - i have a spa3d that weighs about 3.74 pounds (about 1715grams) without any engine installed and i am wondering if the Thunder Tiger gp42 engine would hover it ok. If not do u reckon the TT pro46 would be fine? (46 is quite a bit heavier than the 42)

At nearly 4lb the 42 would probably strugle, it may hover but the pull out would suck (if it would pull out at all) you could make a mouse can pipe for it which would help, i'd go with the 46 and swing a 12x2.75 prop

took it up today with the tt 42 and 11x4 prop and it did GREAT , even did my first hover or what I consider a hover .lol. i just won an auction on ebay for a os 46 so i cant wait to see how that does .
