Title: Engine Selection question - thoughts?
Post by: Randy Powell on March 31, 2007, 08:13:22 PM

OK, so I've started a new plane. About 630 square inches and should come in around 50 oz or thereabouts. I have a Tom Lay reworked OS46VF I'm thinking about for it and also a ROJett .65RE. They are within a 1/4oz or so of each orther for weight so that isn't an issue. Size is similar enough that, with the relatively roomy cowl, either would fit without problems. Prop clearance could be an issue, I guess, but since I'm just starting the plane, I can adapt. I know the ROJett has more giddy-up, but the OS is a very nice running engine with gobs of power. I'm not concerned about the amount of power either way as far as being able to power the plane. Either will do just fine. I did have some problems with the ROJett previously cutting out on hard corners, but I seemed to have remedied that.

Any thoughts?

Hmmm, kind of like asking should you drive your Yenko Camaro, or your Hemi Cuda? If all else is equal... parts availability?

cheers,
Ken

I suppose it will come down to the power type, not amount. Just wondered if folks had any particular thoughts about either.

I'd take the 'Cuda any day of the week and twice on Sunday!

Hay Randy I would use the 46 T/L  I have a  40VF from T/L and it is a sweet heart, that what I'm going to use in my New Imitation Plus II this year.  Good Luck  can't wait to see what your new plane looks like,

I remember launching Ted's TP at the '96 NATS in practice.  OS 46VF.

I like that. A ringing vote!

The OS46VF it is.    H^^

When I have something to take a picture of, I will and post it. Right now all I have is some selected wood, some partially milled engine mounts, some partially milled aluminum engine bolt pads and a curing bellcrank.
