New plane launcher in development

[rifleman_btx]

So far, the power seems good enough, ill be doing a test launch tomorrow. This is v3 in the works now.

Any chance of a video?!?

Yeah when I get the issues worked out completely. I'm not gonna waste anyones time on failure. I'm gonna get this right so others who may want to copy it can do so without failure

Well, it might be fun to see the failures too! Just kidding. I really don't want to see that. But I am interested in building one myself. My flying site is fine for landings but any extended take off becomes a roll of the dice. Thanks for sharing!

No problem, it's almost there just a question of power and launch angle, right now the plane does a back flip at the end of the ramp, so testing if it's over powered first then going go.to Check launch angle

Sorry I need a way to remove this and the following post, YouTube was being a pain, and it cause problems to occur.

rifleman_btx Sweet! It looks like it has the power to launch a 90mm jet!

I've only seen the dog tether bungee launch setups for sailplanes, I've never made one or used one. But I think I remember that the attachment point/hook needs to be forward of the CG. Could that be the issue with the backflip?

It might be it, I got inspired from IBCrazy, and his launcher

[SanExup]

What a great concept! I don't need another project but this is worthy!

We shall find out tomorrow if it's feast or famine.

I hope it's a success!
