Balsa USA Stingray with DLE-20, RC Plane Build N0 16: Installing Engine Mount for the DLE-20 RA

[@anthony3D]

Cet épisode était très zen avec les découpes,les perçages et les collages du bois plus la musique. Les écrous griffes qui s'enfoncent dans le pare feu en gros plan👍😄 j'ai adoré, merci.

Awesome thanks!

One thing I would highly suggest from all my years of turning wrenches... Use blue loctite and not the red. If you ever have to remove that engine mount for whatever reason, it's going to be a bear and require heat to break that red loctite loose. Also, do yourself a favor and pin that firewall in. I use toothpicks or the wood sticks from those long cotton swabs. Just some added insurance, especially with a gas engine. Over 20cc I use aluminum angle you can get at any of the hardware stores on the backside of the firewall as bracing along with pinning the firewall. Other than that, its looking great man, keep up the goodwork!

[@JamesRCPlaneTech]

Thanks I appreciate the suggestions. I was thinking about doweling in the firewall, but thought the double triangle bracing would be strong. But I’ll consider it again, thanks

Nice camera work by the way!

Hello James nice work again I'll have to agree with pervious poster that a hatch is cool way to conceal & keep your smooth lines. I'm looking at that mount and keep thinking that might act like diving board with eng all the way at the ends, I've been known to be wrong before. You could do a mock up now that the holes are set.

[@JamesRCPlaneTech]

Thanks! Ya, I saw the previous post also , and have been considering it. It’s pretty tight space up there , so I’d have to make sure there is room for mountings.

[@stevearmett1565]

Personally I only ever mount petrol engines to metal beam mounts I don't trust plastic to hold up and to be honest they aren't much different price wise and take up less space. I would also have mounted the engine sat on top of the mount rather than having it hang down underneath as that will put more stress on the mount it's designed to be stronger on top unless you have completely inverted the mount ? I am sure it will be fine but you know for next time doing it my way would also mean your mount would have been lower and more central 👍

[@JamesRCPlaneTech]

Thats a good point. I just flipped it and didn’t think about doing it the way you suggested. I’ll have to remember that. Nice! Thanks

[@savageokie3661]

You should look into a transfer punch set. You can find a set for around $20. Use them like an awl.

[@JamesRCPlaneTech]

Thanks. I do have a set of them. Sometimes I forget what tools I have. I do like the awl for wood a plastic, but for sure center punches are useful also.

[@stevearmett1565]

Rather than putting a window or hole in for the carb adjustments I would just make a hatch 👍

[@JamesRCPlaneTech]

I have been thinking about that as well. I will need a hatch for the gas compartment and maybe I’ll do one for the carb as well. I’ll look at it, but the only problem I may run into is making room for any mounting needed to support it. It’s super tight up there.

Merci pour la vidéo et le pot d'echappement aura T il bien sa place ?

[@JamesRCPlaneTech]

Yes, will be good. Thanks!

[@HenryTyson]

Sir, could you tell which engine mount that is, I have the same motor in aP40 TF

[@JamesRCPlaneTech]

Hello , this is a Great Planes adjustable 1.20 to 1.80 mount. I modified by cutting the center out so the DLE could fit (check the video if interested). Great Planes is no longer in business, but you can still find them on eBay and other sites. They made a few sizes, so check. For the DLE 20 in the future, I would probably use one of the mounts that are available from Red Wing hobby or Valley View RC or similar. Thanks

[@joepellissier2091]

Well done…sure you couldn’t go with a bigger motor…lol

[@JamesRCPlaneTech]

Ha! The specs say up to a 30cc ! I’m used to glow, this thing takes up lots of room.

[@duainrothman7930]

Ok my mistake I didn't watch to the end

[@JamesRCPlaneTech]

The mount options for this engine have been a little puzzling for me. It’s a popular engine but it seams like there is not a well established mount to use for it. We’ll see how this one works.
