4stroke upside down in plane
I have a spectra pattern plane and it has a 40 size 2stroke in it, I want to go to a 61 size 4 stroke but the engine will have to go in inverted. What would be the most reliable engine to install upside down? I don't want to have to change the mounts to make it a 45deg. or 90deg. setup unless I have to. I am also putting a 61 on my Tiger Trainer, I have already taken out the dihedral and increased the throws where I can do some aerobatics with it, but I cant go too far with it where I can't use it to teach my nephew with. It has the stock GP42 on it and I need a bit more torque and power, so I feel the quietness of the 4stroke will be the best bet.
Thanks for your advice in advance.

All 4 strokes will run inverted as well as upright, just be sure the tank is mounted in the right position, mid point of the carb. if it makes you feel better you can install an on-board glow lite. just be carefull and don't flood on starting. Always flip prop by hand with dead plug before applying elec. starter
