Hey
What is your empty weight of your RV4? Which engine and equipment?
Vans says 903-913 lbs, with Lyc 320 and VFR instrumentation? The Lyc 320 engine is 306lbs +?
My question is do you think it will be possible to build the RV4 with an empty weight down to 830 lbs, 70+ lbs down from std weight.
No paint, polish only, minimum interior and instrumentation VFR only, lightweight seats, lightweight battery, choose prop by weight, fixed pitch, no vacum, el ignition, etc… But no compromise on safety
Then the engine, the Lyc 200 series would be to weak and the ROTAX series to weak and light?
The Titan X340 is estimated to be from 260-290 lbs and the Lyc 320 is from 306 lbs. There might be 50 lbs weight saving from only the engine.
Is this a realistic project?
Will there be problems with the weight and balance by removing 50 lbs firewall forward? Possible to move the engine further forward? Options on engine mounts?
Your thoughts?
Thnx
