Default Magnum with Nelson, OK?

I'm finished mounting a Q500 Nelson engine in a Magnum ARF. Because I only have the backplane mount version, I was forced to do another firewall. After some work, it's done.
I will be flying it in a week or so (business trip), but I was wondering if anybody have already mounted one of these engines in a Magnum. Mostly thinking if the wing is strong enough to handle the Nelson.
Anyone?

Thanks,
Edgar

Default I don't see why not....

....If it's a side-pipe Nelson....be sure to lateral balance
the left wing.

Good speed to ya'....

Dave.

Edgar,

I whacked a tree with my 1st Magnum (remember to use high rates when you slow it down) and the wing proved to be very strong. It is everything else I would worry about if your engine turns much more than 22k. Linkage must have zero slop, control surface alignment should be dead on, top line servos, reinforce stab, etc, etc..

Thanks!
I just got in from a trip, so I can probably do the maiden in a couple of days. It's indeed a side-exhaust Nelson.

How much is just the airframe? I may want to buy another one if my engine is OK.
