Which engine for a Bridi Aircruiser 60
The specs on the plane are as follows:
Wing span: 61 3/4"
Wing area: 720 sq. in.
Length: 51"
Weight (approx.): 5 1/2 lb.
It seems like a .60 engine is too much for this plane. Would a good .40 or .46 be better?

Better? I don't know what that means in this case. The Aircruiser 60 will fly on a 25 if you want. It all depends on how much reserve power you want.
Consider this: A 61 at half throttle burns less fuel, makes less noise and less vibration than a 40 at full throttle and gives the same power. And will last forever.

In this case, I am building the plane for someone to learn on and I want to make sure the engine is an appropriate match for the plane and for a beginner.

According to the bridiairplanes.com website, the Aircruiser 60 is a .40 to .60 size airplane. Clearly a 40 would be better suited to training than a 60.
Are you his instructor? If not, you probably should ask him because his preference is more important at this stage than yours, mine or the student's.

RE: Which engine for a Bridi Aircruiser 60
I don't know who the instructor will be or even who the student will be. I am building this as part of the "Pay It Forward" threads in the Beginner forum. I am donating and building the plane and others are donating the engine, radio equipment and accessories. I am just about to start the build. The build thread is at http://www.rcuniverse.com/forum/m_37...tm.htm#3751609. One of the contributors has a Magnum .40 and another contributor has an older OS .60 but I don't know which of the two engines would be more appropriate for its intended use.

Always get the larger engine. A newbie learning to take off with a model that is underpowered is asking for trouble. A little too much elevator and; stall, crash, and it's time to rebuild. The first kit I built was a Top Flite Cub, .40-.60 size engine recommended. Not having much money at the time, I opted for the .40 size engine. BAD IDEA. On the first takeoff, I held a bit too much elevator. That .40 just didn't have the power for climbing out after takeoff. I never tried the smaller engine trick again.

I have a couple old K&B 61 engines that just keep on keep-en on! Finally had to replace the bearings. Treated right they will run forever. I run some castor in my fuel.Logair

I have the kit in my attic and a brand new magnum 52 that I will put on it. Years ago I bought one of these at a garage sale with engine and radio for a hundred bucks. It had a super tiger 60 on it and it was a match made in heaven. Man that engine ran well. IIRC it had the dished head.
A really good 46 would probably be ok but just a little more power might be better. Here is a pic of the engine in one of my scratch built designs.
