From the MVVS Canada website: "This combo spins a Menz "S" 18x8 propeller at 8400 rpm, producing approximately 17 pounds of static thrust! On a 10-14 pound aerobatic airplane
I made my mind. Yesterday I ordered MVVS 1.6 from justengines (UK). I saw all sources in USA are backordered so I turned to UK. Even with insane exchange rate the price is fine (we don't pay UK VAT here).

.870 is very close to 7/8. most alum. bar stock or any metal comes in a few thousands shy of what it's suppose to be. I don't see why a 7/8 carbon fiber tube wouldn't work. If it's tight, just do a little sanding. .005 isn't much.
As for the wing tube I measured it with digital caliper. It looks like it is pure metric size as OD is exactly 22.00mm and length is 650 mm. I just sent an e-mail to pbgcomposites with question what can I do about it.
Regarding the weight I checked with powe********* asking them how it is possible to make 9lb of ths plane. The answer was fast but kind of funy saying that dhis plane is discontinued and was not intended for 3D. Hmmm - I don't know what to think about that.
I just finished fixing my H9 Edge (1.2 size) from ninor damage (Crosswind and pilots error made it to run into the cage) so I'm starting assembly this Powergobbies Edge.
I checked all parts again and I can say it is beautyfull plane
Very nice design and well built. All parts fit very well. I don't want to be rude to H9 but Powerhobbies Edge looks much better in design and quality. It is built light and strong. I can't find any place in structure that is overbuilt or not strong enough (I noticed a couple weak spots in H9 Edge that I had to fix). Wish me luck.

I need to add this. Guys, if you need MVVS in USA, don't wait for back-order or preorder the stuff. I've never meet such friendly person as Paul from justengines in UK.
I ordered my MVVS there yesterday, and today it is on the way to USA. total 300 GBP for the engine, BCS muffler, alu spinner with adapter and 3 wooden props shipped air right away Even with this insane exchange rates (about $575) I couldn't find a better deal.
