Yes we could just make it there from here.

Just curious about how your flight testing is going. Is the UL engine performing the way you had hoped?

Default Flight testing

Over all the aircraft and engine are performing as advertised.
The engine is very smooth and easy to operate.
The cylinder temps are in the 260 to 280 F @ 95 to 100 F ambient.
The main issue is the Oil temps. They are higher than I want.
We are in the process of trying different solutions.
Since this cowl was a not specifically designed for this combination, we were not able to mount the Heat exchanger in the best possible location for airflow.
I see the Rotax may be having similar issues per another post.
Ul Power is in the process of having a cowl made specifically to meet the engine and airframe. We plan to be at Oshkosh with the aircraft.
Stop by to see if possible we welcome the feedback.

Regards

Well I can verify it made it to Oshkosh, got to chat with Al and Brenda while there. Sure seemed to be a nice combination.

Default UL Power Engine.

We are still waiting on delivery of a new designed cowl.
The vendor made the needed measurements in early Oct.
Our understanding is that it will sent soon for us to fit.
We made a change to the oil cooling which seems to have solved the high oil temps.
The plane is down now for changes to the larger sky-view screen and the landing gear modification.
Overall we are very pleased with its performance and support.

Brenda and AL

Hi Brenda.
I'm also looking for comparison numbers against the Rotax. Is there a firewall fwd kit in our future? If the numbers are acceptable I suspect the market might be considerable...especially if it is done as complete and turnkey as the Vans kit.
Good luck with the gear mods - I just got my kit yesterday!

We will compile numbers once we get flying again in January.
Contact Robert Helms at ULPower.net as they are working with a vendor on a firewall FWD package.
