[sm=rolleyes.gif] I am building a 82" stand off scale Eindecker III from an old Sr. Telemaster wing. I have a almost new Super Tiger 90. TO be scale I need to swing a 20 inch prop (18 would still look good). Would a deisel work? what is the cheepest way to convert to a deisel? Thanks all!!

I have run up to a 16/8 Apc on my st90 w/Davis head on 81" GP Cub ARF on floats. I would think the new 18/6 wide blade 3D prop would work on the st90/Davis diesel head. I think Zinger makes an 18/6 wood prop, which would look better.

I made the mistake Davis warns about: running too rich and overcompressed. This carbons things up real fast. The ring sticks, compression is lost and it won't run.

So make sure it is lean enough.

Fox 35what is your 16x8 turning at on the ST90 coversion??
