Status: offline 		The big brown airplane truck was here again today, and this time they (Tower) got it right. Man, this bird is really nice! I didn't get a chance to dig real deep into the box yet, but I eyeballed all the parts looking for damage, and there was none to be found. I know some pics have already been posted, but I'm going to try to get some good close-ups of the components posted because I think it's really well built and designed. I perused the assembly manual and realized that it's set up for dual elevator servos, which had escaped my notice until then. I view that as a plus because it solves issues related to flex between the two sides. There are also SIX cutouts in the tail to allow a bit of flexibility when it comes to mounting your servos.

As excited as I am about this plane, I probably won't get started on it until after the holidays.

Status: offline 		Just a note about an error in the manual. On fitting your engine to the engine mount. The picture shows 4-5/16" from front of drive washer to firewall. The text reads 4-15/16" from front of drive washer to firewall.

The text is correct! should be 4-15/16"

Status: offline 		Ok, I got mine all together, but have not flown it. Need to brake in the engine, and the weather is not very good now either. All up wieght (dry) is 93.1 oz. Thats is with a JR 7 ch Rx (mounted as far aft as possible in bay), 720mil 4 cell MIMH batt (just forward of the tail servos for balance), OS FS70 II surpass with the 90 deg inside muffler adapter, and a APC 14x4W prop. HS 81mg on the throttle, mounted in the most aft bay under the hatch. CG is just about as the manual states (4.75" aft of LE), perhaps just a touch aft.

The manual says 745sq in wing area, Tower says 702sq isn wing area. so wing loading is either 17.99 or 19.1. I would have to say that 18 would be nice and floaty, 19 should be ok too!

Status: offline 		Sounds great Mark. I'm hoping to start mine soon after the holidays. Do you have any pics of the assembly process? Any words of wisdom or warnings we need to know about? I am very anxious to read a flight report and hope the weather breaks for you soon.

Erik

Status: offline 		fayrwerks,

I don't think anyone has any flight reports on this particular plane yet. However, based on my limited experience, I think the 46 AX would definitely hover the Reactor. With light equipment you should be able to come in somewhere between 5 and 5.5 pounds. You probably won't have explosive vertical performance, but you should be able to climb out with a bit of authority. This is just my impression based on what I've read.

Hope this helps,

Erik

Status: offline 		I have flown a 4 lb Burrito with an OS 46. It was barely OK. The 46 develops about 7 lbs static thrust. I have a Saito 91 on my 5.5 lb profile. I would not like a 46 on a 5.5 lb plane.

Anyone know if this plane can be modified to accept standard size servos?


I'd bet money on it. I haven't taken mine out of the packaging yet, but given that it's a .40-sized plane, I'm certain that anyone with a little experience and ambition could do it. It may alter the flying weight, however, and therefore the flying characteristics. If you put standard servos in the tail, you will probably be adding at least an extra 2 ounces back there, which could equate to needing several ounces on the nose to make it balance properly. Until a few are built and reported on, we won't really know how the plane tends to balance. You could be the first one to do the standard servo mod and let us know how it goes. :-)

As far as pics, I'll hopefully be starting on mine next week and plan to start an official build thread to document the process.

Status: offline 		mmmdowning,

I'd love to hear about your electric version as it comes together. Those 225MGs should really be a nice combo with the plane. And I agree, it looks really nice. If it flies as good as it looks, it ought to become very popular.
