I was wondering if anyone had a RCV90SP that I could rent for a fit test on a four engine build. The Palmer 132" C-130. Please post or PM me if you could let me rent it from you for a few days. Thanks

Can I ask,,,why so much power??? that 90 would yank that plane with just one engine..That is a gear reduction engine made for using HUGE props,,,how big do you need or want the props to be???..that engine will turn a 18-8 4 blade with ease,,and it may not be a big enough prop to keep it in range of the max RPM...

The 90 is not that powerful, it swings a large prop because it has lower rpms. I have a 90 in my 12 lb Sea Fury and it just has enough power. That C-132 is going to weigh alot more than 12lbs

So you think youll need 4 of these to pull a 132 inch C-130..you have got to kidding me...hehehehe,,I hate when people do that...try to make people look dumb,,,that engine will swing a HUGE prop...on a 132 inch c-130,,,scale prop would be around 15-6 or 8...3 BLADE....that engine swings a 4 blade with ease...i've owned ALL of them..60 -90 and the 120...and if you look at the owners manual,,,you will see there is not much differance between all of the 3...bout and inch on the blade size,,,is about it...other than that,,that engine at full bore should go about 5900 RPM...just my 2 cents here,,,but ill bet that plane calls for 40's or 60 2 strokes....hey,,,we all like to overpower the planes sometimes,,but dont you think that would look odd with those HUGE props,,that dont look scale" just about hitting each other....hmmmmmmmm

2 90's in a 19lb B25. You said that your unbuilt parts (the box) weighed in at 17lb. And you're gonna put 4 of these puppies in? [X(]

The 90's will use a 15.5" 4 blade (or 15.75 3 blade) so they will fit (your other thread). Your desired 13" prop (again, on your other thread) is too small http://www.rcvengines.com/rcv90sp.htm
