Cool
Why Doesnt 3DHS and EF do this?

just came across this.
Maxford Globe/TEMCO Swift ARF video review (4 min 27 sec)


i love the adjustable sliding motor box! and the magnetic cowl.
would add a hair of weight but not much. pretty cool ideas i hadnt seen before. at least not me personally.

I can tell you why we don't. The first blender or KE spin would rip that motor box and cowl right off the front of the plane. That is a scale model intended for much more docile flying than the torture that the EXPs are built to withstand.

the motor mount and cowling isn't that big of a deal if you use the recommended or equivalent equipment.

What would be cool though, would be magnets for the SFGs that could hold up to the flight abuse, but still be easily removable for transport.

it's also going out of one's way to weaken the structure to counter for corner cases... with a properly developed product, it will already accept a wide range of motors with little fuss, those people who would actually need this feature would be very few. Need to keep the corner cases as the corner cases... make sure the core product stays as good as you can make it for the core customer.

even when bolted and epoxied it? it appeared to have bolt holes.

i aggree. i rarely have to do much in the way of stand-offs. i guess i just thought it was cool. maybe not really needed for us, but cool. i had never seen that done before.

that would be tits!
if they can hold on the upcoming bipes wings with magnets, i would think SFGs might be possible?

I think it would be easier to hold a wing on with magnets than a sfg since there isn't much side force on a wing, just force from lift mostly. There must be a lot of force on a sfg especially when doing things like a ke wall. But I don't really know.

TG's on the right track methinks... SFG's are subject to too much varying load for magnets; various pitch angles, top of SFG is getting very different turbulence than the bottom. Could try it, but I'd bet money that they'll depart the airplane. I don't mind the thumb screws or even regular bolts and washers.

...magnets holding wings in are different, not much in the way of sideways forces on wings, friction on the wing tube is helping keep the wing on, etc.

magnets holding wings on when the wings have SFGs may produce similar concerns to holding SFGs on with magnets.

the forces are different, and have different moments...

I wouldn't trust wings held on by magnets even without SFG's. They would come off in a KE spin IMO.
