The 23/10 will swing about at about 6700-6900 depending on the prop combo. As T3beatz states the engine will also swing the 24/8. It all depends on the airframe and what you want to do with it in the air! You will not go wrong with the 23/10.
I have a selection of props every time I fly a new plane, and I will ''dial'' in the engine/prop combo over a couple of weeks of flying.
The 50cc pics that T3beatz posted. Interesting eh!!!!!
There ARE 2 versions of the RCGF 50cc. One has the cast crankcase and one is cnc'd out of billet aluminum. The one posted on the zrcgf. com site is the cast crankcase. This is because the we are still testing and evaluating the new model engine. Still some minor issues, that we are working through with the factory, and it will be ready for prime time. We will be updating the web site with the new model very shortly. Our next shipment will have the Aerovate 50cc B engine complete with all the mods/tweaks in 'em. It will update the current 50cc line.
We are very particular about releasing an engine to our customers until it has the Aerovate quality aspect that we expect. The Aerovate engines are spec'd and built by the factory to specific standards that we have developed.
As to the appearance of the engines looking like the DA.... YUP......in fact they are DA cylinders. There are only 2 cylinder manufacturers in China, that make 'em for ALL 2 stroke engines (this includes lawnmowers, chainsaws, weedeaters etc etc etc). The factory picked the cylinder. The Aerovate 62cc.... it uses the same cylinder as the G62 engine.....
The Aerovate engines are not knockoffs, but do have similarities with other engines. The engineering INSIDE the engines is what makes and sets them apart. The performance aspects of the engines are mostly leaders and not followers.
The XYZ and Turnigy are one and the same. I have few comments on these engines.
The TBZ props are produced by the boys that used to run/own the XOAR props and left to pursue other opportunities. Great looking props. (Both of them!!!!) Both are GREAT performers too.
