Piston Power - test plane 2.1

9,903 MethaManAerospace  3.1 years ago
Auto Credit Based on MethaManAerospace's - - - - - test plane

This is the latest development on the radial piston engine front, I have been testing the possible uses of the 18 cylinder radial engine and it works quite well to power a twin engined aircraft. More testing is required but it flies quite well!

Included is the RAD 18 v1.1 piston engine on its mount and circular firewall.

- VTOL = prop pitch

how to fly:
- make sure that both engines spin in the same direction (preferably clockwise if looking in chase view). If they don't then restart until it works (sorry).
- slide pitch to half way and throttle 50%
- gain speed
- gradually increase throttle to 90% + prop pitch to last notch (almost)
- take off speed approx. 90 / 100 mph
- full throttle + prop pitch
- flyaway!

how to use RAD X 18 v1.1 engine:
- save as sub assembly
- prepare a simple place to mount it easily
- mount it however
- good luck!
- /!\ this engine can be mirrored, however some connections are lost and the engine is less reliable, be warned...

This was the first step in the development of this radial engine and there are more to come! stay tuned :)

    @LimitedShelf568 IKR ! Not quite as unpractical though! Thanks for the upvote!

    @CDRxavier It replicates a radial engine, the double wasp. Sure it's not the best engine but that's why there's a development stage, right? Thanks for the upvote BTW!

    Well I have to say sorry, but I am not really appreciating this thing.
    I mean, this is cool, but...
    Do you really need 18 pistons?
