Hello Pilots

Here is my new RCV 91-CD four stroke engine.   26.96 oz.  WOW this thing is huge but the height is smaller than
most other .91 4strokes.

I guess this is what we use to move these big scale planes around with, It does have some weight but i guess that
will help with tail heavy WW1 planes.  There must be some major line tension going on when flying a CL Scale
plane that uses an engine this size?  But line tinsion is good......

My Fokker D7 Plans will be arriving this week so then i will get busy on this new project.  I'll keep you posted.

My, Brian!  Our WAM club prez built a 1/4 scale Fokker DVII and flew it on 60 ft. lines...but he used a Fox Golden Eagle .60...
Looked like it was dragging its tail while Joe whipped it around...A four stroke with the right amt. of power will make memorable flights!

It's been my experiance that the RCV engines do not have the power of an OS Max etc.  Also they need a lot of fuel run through them before they devolip full power. Mine took 3 gallions or so before it was ok.  Read the instructions. They also like higher nitro then you might think. Their strong point is the small size. They seem to be a good engine but I have gone back to 2 cycle. Cheeper, lighter, stronger but the 4C sounds better.  Don't worry about the pull, it won't be that bad. The RCV 90 has the power of a standard 2C 60. Scale usually weighs more than stunt ships and needs the power.

Also consider an adjustable line guide so you can adjust how much line tension you get, on the bigger models I adjust the location of the line guide  fwd if the line tension is too high.
