i am considering the world models 46 mustang as my next project and was wondering would an irvine 53 pull this plane well and would the irvine run well inverted would i need remoteglow????? any suggestions???

WM .40 size is a nice plane. I had been flying mine for 6 months untile last saturday when I had a completely radio failure . Most of the parts and engine were reusable and will be getting another this week. I ran a ST G90 sideways in it which was a bit much but so what. The Irvine 53 should be okay.

A great combination for this plane is a 70 size four stroke. I had an OS FS-70 II in mine and it flew great.

A better combination is a Saito .91 4C... two oz. more than the OS .70 and goes like a scalded ape with an 11x12 APC prop.

BTW I originally had an OS .70 on mine. It flew quite well with a 12x7 prop. It also balanced perfectly with that engine - no extra weight was required. I didn't even have to futz with the placement of the receiver or battery pack... I simply ziptied them to a former on the CG. Battery pack in front, receiver behind.

When I swapped in the bigger Saito I had to shift the battery - I ziptied it to the rear of the receiver and it balanced fine.

OTOH your Irvine .53 will pull it just fine. Be prepared to add a couple of ounces to the nose in order to balance it. Stick with 12" diameter props for a while - the plane responds quite well to the extra propblast over the wing at low speeds. Your landings will be a lot smoother.

I ran a 13x6 MAS with my OS FS-70 II on the WM P-50 and it is real sweet. Maybe not as outright fast as the Saito .91 but it just seems to fly very well with no need for extra weight.

I had the dago red version with an 80 four-stroke and it was very fast. I think you would get up toward 100 mph with an Irvine 53. Try it, I think it will be a winner.

I have used an Enya 50 and, more recently, an OS 46 FX (both 2C) with 11" or 10" prop. Its not as fast as the 70 or 91, but I am happy with it. I've been flying this model for several years and it is a favorite of mine.

I have an FS 70 Surpass in mine, more than enough power!
