J. The aluminium spacers need something behind them, they will ‘eat’ into the wood over the first few runs moving the engine back. We used ‘penny washers’ 1.6mm thick 25mm dia and I Hysol those to the wood so they don’t chatter. The 230 seems to run smoothly, but it’s a shaker with the huge firing pulse/torque

[@tjh44961]

That engine is incredible! I've been waiting for further installments on this series. One suggestion -- when making cutouts in fiberglass or metal, like your hatch on the bottom of the engine compartment, you should never make square corners, they should be radiused. If for some reason the airframe should be stressed in that area, for instance if it and terra firma tried to occupy the same space at the same time, those sharp corners will be stress risers, and the cracks will start in those corners. And just a point of terminology, the aerodynamic cover over the propeller hub is called a "spinner." Looking forward to the next installment in this project.

[@thelightersideofrc]

Great suggestions and info! Thank you.

Great video and information! That firewall seems extraordinarily flimsy, I would have assumed considering the size of the engine, something made of carbon fiber or at least reinforced fiberglass.

[@thelightersideofrc]

Thank you! The base or starting point of the firewall is not up to the task for any engine. It’s strong and carbon reinforced but requires the appropriate install kit. Some guys fly this plane with a single cylinder 80, an in-line 155 so the install kit finishes off the required items. Lots of aero epoxy needed!

[@thelightersideofrc]

Thanks! Yea the thrust angle is built into the firewall and cowl.

[@gonzodagreek8560]

Hi Jonathan, so happy to see this build starting. I'm a novice prop guy so I don't know with absolutely surety, but....was wondering if the original un-shimmed alignment of the engine isn't actually "off" but rather built into the forming of the fuselage in order to address 'thrust angle' of the engine. I think prop engines want to point up and right to offset torque thrust which is consistent with the shims you added. Any thought on this? - Gonzo

[@thelightersideofrc]

The thrust compensation is built into the firewall and cowl. Just slight adjustments

[@gonzodagreek8560]

@@thelightersideofrc Correcting myself: Thrust adjustment of a prop engine is 'down and right'. Good luck with the build.

[@louwrensvanniekerk8104]

It will be cool to see one with a turboprop engine fitted

[@thelightersideofrc]

Hey that would be different

[@brianroberts5062]

I'm not sure you are mounting the engine correctly. You did say that you had no manual. These large Gas engines need down and right thrust otherwise the torque from the motor will cause major issues. I know that doing this destroys the symmetry of the cowl and the spinner but that is unfortunately the way these need to be mounted. I am in the process of building a super scale 3200mm P-38 that runs 2 x Roto twin cyl 85 FSI UAV engines with electric start and generators. I have not uploaded the engine instal videos to youtube yet but there is about a 1cm gap on the cowl top and on the left side, extra spacing when compared to both right and top. The P-38 is from WindRC and I worked with the factory to get the model built for the Rotos and they built the correct thrust angles into the firewall install itself. You may want to check around with CARF about a build manual and thrust recommendations. From your video I picked up that the firewall already had down thrust pre built. I could not determine if there was also any right thrust. I assume that the engine turns counter clockwise? KOLM do both rotation directions so maybe that was not pre built. I turned up aluminium spacers for both left and right engines on my lathe as the right engine needed an additional 2mm length to fit the cowl on that side. You may need to make your own spacers to push the motor forward the get the correct thrust angle. This is a good reference but you should get the exact angles from CARF. rckavalaacroteam.com/rc-engines-right-thrust/

[@thelightersideofrc]

Hello Brian. The firewall does have down and right thrust built in. The CARF Strega is pretty much designed for this engine but others have installed the 155 Inline Kolm or other smaller engines which requires a lot of redesign. Thanks for the information!

[@flyboywbl]

Yay!! this is awesome. Question, Won't moving the engine throw off your thrust angles?

[@thelightersideofrc]

Engine Firewall is offset to the proper angle in the mold along with the face of the cowl. So getting engine aligned to this is critical.

[@flyboywbl]

@@thelightersideofrc gotcha.

[@doughughes5107]

Great video John. Was it necessary to introduce side and down thrust angle on the engine instal? To compensate for torque twist? Superb method of hatch build.!

[@thelightersideofrc]

Yes for sure. The compensation is built into the firewall

[@ArneChristianRosenfeldt]

An inline3 Rocks end to end. Counter to the rotation. I wonder what the propeller says to this. I propose a flywheel in the back with the same weight and inertia as the propeller+hub. Then mount the engine cg on a gimbal mount to keep the light part of the plane free of vibration.

[@artpeck9272]

@@thelightersideofrc Sorry, I wasn’t being critical! I was just wondering if the shims you had to use to square things up might have inadvertently cancelled out the built in thrust angle. It’s a beautiful model and an amazing engine.

[@thelightersideofrc]

@@artpeck9272 hey Art. Oh no problem at all. I understand the question. Basically the firewall has the angle built in. It’s designed for this engine so the backplate also needs to line up to the cowl. So the reason for the small shims was to get the spinner in the right location for it to all jive. 😵‍💫😊😊

[@artpeck9272]

@@thelightersideofrc When I built r/c models many moons ago, we did the same thing. Our club built a set of templates that we passed around to build a version of the RC Modeler Ugly Stik. We had set the thrust angle in the templates, but it never seemed to be perfect. So, like you did, the builder had to stick in some shims to get the alignment just right. Ha! I just remembered we had to lobby our local hobby shop to get a selection of K&S brass washers.
