Last year (darn , it might have been the year before that.) I picked up a nice Tempest 40  from another flyer wanting to put some funds back in the bank. I haven’t flown it since the day I bought it, and since he removed his engine, I have to replace it. It was originally set up for an FP or LA and when I got it he was removing his 46 LA . Since the mounts and nose ring were all set to this size I should just use one of these but I have two problems, first I don’t have any LA engines  , although I do have a NIB 35 FP-S. I also have a bunch of other engines including various Super Tigres, Max-S, and a Silver Foxx 40 that is close to a straight drop in. If I open up the mounting holes on the Fox slightly, it’s in like Flynn . Secondly, the person I bought it from was adding mega mass to the nose to desensitize it for me . I flew it a couple times before removing his engine and it flew fine, just some unequal runs from the clunk tank height being to low and not able to raise it. I feel like I need to buy an LA for it but (flame proof attire on) I just don’t want to spend good money on junk engines .

Also, I noticed it has an adjustable elevator horn and there is room to move the elevator pushrod down, so maybe I won’t have to use a brick up front, will that work ? What else will come close to bolting into the FP /LA mounts ?

I don't know if this is the right place to ask about props but it is powertrain related. I picked up a used Brian Eather 12 x 3.625, flat face 3 blade carbon prop from a guy for the Tempest 40. It was supposed to be an 11" which I figured I could trim down a little if it was too much load. I'm guessing that rather than trying to trim this prop should it be used for something else? Also Is it better to repitch a stunt prop up in pitch or down in pitch?

I decided on the Silver Foxx 40. I hope to run it in a high/low style, if that doesn't work I'll just use more pitch.

Really curious about whether it's better to start with too much pitch and reduce, or start with too little and increase pitch? I think I remember Ted saying more pitch at the tip helps the corner, but it seems like most people start with more pitch and reduce, which gives less at the tips.
