Of course they may not be quite as long as the quads, but the quads are so-so much smoother.

Just make sure the firewall is solid and it's all good. Try to keep from adding anymore weight than necessary.
Also the composite Fuselage will hold a lot of airplane. Think of mounting the airplane by the firewall, and hanging it from a stand. This fuse will hold itself there.
A lot different bird than you are used to Brent. Top shelf for sure.
Jack sorry for the poor color shots.

Re: The never ending engine thread, East-West

No, I knew it was a composite fuse, the thing that just looks funny is how small a footprint of the mount is in relationship to the width of the engine.

Then ya go and show the actual plane!

The mount is actually the size of a 170cc engine. Width is only that of a 100cc engine. Length, of course twins are shorter. Prop hub of a 170cc engine.

The mounting lugs are very very stout. If you rip the firewall off...shame on you!!!

Not sure if that helps you out.

Re: The never ending engine thread, East-West

Brent with over 20HP. Think of a firewall that you can hang the rest of the airframe from.
Which is the case for any airframe, even a 6lb airframe should be able to be suspended horizontally from the motor mounting bolts.
Hope this helps.

Well Jack it's all loaded up in the Aircraft Carrier.
See you in the morning.

This can't be the primary or only advantage of a quad Jack... If smooth was your primary goal, well, see my post in Gordon's "smoothest 120" thread

They've definitely got "cool factor" and sometimes that's all it takes, but in most respects the big twins seem to compete very well... What draws you and all the IMAC guys to them?

Re: The never ending engine thread, East-West

Dale, planes the can really punch out of a hover probably have 1.5 to 2.0 thrust to weight ratio. At thrust:weight of 2.0, the firewall has to handle double the weight of the plane. That's all static. Add in dynamic loads from vibration, and firewall probably should handle more than double the plane weight.
