SynergyPilot,
You will need a lot of throttle management since FS110 will be way over powered for the plane.
Stock gear may not have enough ground clearance for anything longer than 13''. (stock setup is 13x6) I am using Bolly F3A carbon gear on mine that is taller than stock.
It may become too fast even for landing since the FS110 will need at least 13x9 or higher pitch.
You may want to beef up the LG plate mounting also.
Good luck,
Hi PatternFlyer,
I think that the OS FS110 will be ideal for that model. The weight will be approx 2.600 kg - typical weight for the classic F3A aircrafts from the 70's where I was using OS HANNO SPEC. 61 and WEBRA SPEED 61 with long tuned pipes. Wingspan was slightly the same 1400 - 1500 mm. They were designed with fuses very slim and not like the modern ships like OSMOMSE, OXALYS, VALIANT etc, where a big, thick and high fuse enables more control, lower constant speed and brilliant KE abilities.
The FS-110 Alpha weighs 600 gram - on the spot. 1.8 hp
The FS-70 Ultimate weighs 480 gram approx. 1.2 hp (I am using this engine in my OXALYS 50)
The WEBRA SPEED 61 weighs 445 gram. 1.96 hp
Weightwise I am dealing with managing 150 gram more weight using the same components - no additional led weight in the rear.
Prop size will be 13 x 6-8 x 3 (Three blade prop) supporting the slower constant speed in the downlines even more.
And yes - LG plate and the LG itself might need to be replaced to something higher, lighter and stiffer. Unfortenately BOLLY seems to have been forced to close their business down. Do you know if there still is some left over dealer stock somewhere - I would be greatful.
I talked to Hatori Japan and they will be manufacturing the cooling header for the OS FS-110 Alpha during december this year. I will be using that one with the short pipe. It fits like a schmack - using that config in the oxalys and the sound is brilliant and very silent.
Hope to hear more ideas and thoughts around this overpowered beast.
