Micro Stomper E20/Capacitor plane

[@zoltore23]

So...I am 57 years old. I remember those balsa wood airplanes. I remember winding up the rubber bands so much that the whole airplane crunches up. I moved up from those models where you would pin down the pieces on a grid (no super glue back then). I remember using dope to tighten up the tissue. Then I tried putting engine in them. Sadly most crashed. You have INSPIRED me to get back into the hobby. Thank you!

[@joshuawfinn]

These are the stories I love! Let me know if there's anything I can do to help you on your return to model airplane bliss!

[@GrandadIsAnOldMan]

Glad you ran it with the capacitor, lovely to see that 😊👍

[@joshuawfinn]

The capacitor units are a game changer. They've been around for 15 years but are getting really good now.

[@archivist17]

@@joshuawfinn I must admit I enjoy the capacitor planes.

I built a Stomper a long time ago when I was a teenager. I only had an AM10 to go in it. It flew fine as a sports model but was underpowered. More recently I have flown Dixielanders with electric motors. I flew one in an open electric flyoff with George Fuller timing and won. He was delighted. Unfortunately he was starting to be ill . With the c of g further forward it is an exellent model to fly for fun. With the c of g on the trailing edge it can climb fast and is very competitive. Here in England there is going to be a Dixielander competition this season. I’ve flown a mini Pearl in E36 electric. I think it was a Don de Loach kit. Taming yours when so overpowered was impressive. I really enjoyed your video.

[@joshuawfinn]

Dixielander is a good airplane. BMJR is talking about making a kit for the full sized one. I'm considering a reduced version for 1/2A Nostalgia. Pearl is of course a descendent of it...quite a little powerhouse. Mine is a good flier.

What a cute little critter u have there Joshua ! With crazy loops and rolls in first flights to lovely long circle flights to end ! Real beauty !👍👍

[@bobcanada3656]

are you using wing washout on the wingtips? Especially the right wing. It looks like your right wing is tip stalling. It also looks like the engine could use a about 3 degrees down thrust along with your left you have build in.

[@joshuawfinn]

I can see the possibility of downthrust helping. Washout is already present. The reality is the Stomper wasn't designed to operate at high power levels with a high wingloading as seen on E20 planes. If you notice, it's really happy on the capacitor setup and I've since kept it with that since it'll fly over 2 minutes in dead air consistently on that.

[@bobcanada3656]

@@joshuawfinn Excellent time. Can't argue with that. I just like the idea of a more efficient wing when trimmed closer level wings in the turns. JMO.I remember reading somewhere that the F6F Hellcat had 6 degrees down thrust.

[@woutmoerman711]

Thanks for the video, Joshua! Here in the Netherlands the Pearl is popular in e36. Great platform. (Oops, I wrote e30 at first but it is corrected now)

[@curtis5445]

Excellent! So enjoyable to hear the history, trim it and fly it. Thank you.

[@joshuawfinn]

I'm a history geek if you can't tell. 😀

[@urdooinitrong7753]

wow! What a beauty Josh! I loved the evolution of trimming. Such a major improvement! Makes your trees even more terrifying... Could you cut them down and build a cabin maybe??

[@joshuawfinn]

Gonna sell the trees for lumber eventually. 😉

[@archivist17]

@@joshuawfinn ...and grow balsa in its place? 😀

[@russedmonds227]

Could having the cg so far back on the wing be part of the over elevation problem?

[@joshuawfinn]

Actually other way around. Aft CG allows less incidence to be used to achieve steady glide.

[@russedmonds227]

@@joshuawfinn doesn't an aft cg cause a nose up pitching moment?

[@joshuawfinn]

@@russedmonds227 only if it's accompanied by excessive incidence. Obviously there's an aft limit at which the stability goes neutral and then negative, but there's also an optimum just forward of the aft limit where the magic happens.

[@russedmonds227]

@@joshuawfinn Ok I get it. Thanks Josh !

Hermoso modelo y lo bien que vuela. Felicidades

[@woutmoerman711]

What's not clear to me is the exact difference between the first half of the video and the part from 11:00. The second half has a longer motor run but less power, but why?

[@joshuawfinn]

Up to that point I was flying it on an E20 setup which is pretty powerful and challenging to trim. The second power system is a capacitor--super fast charging, lightweight, easy to trim.

[@mikedunn7795]

Nice model,and great flights towards the end! I grew up with rubber models,including a soldered wire frame,silk covered rubber powered model my dad bought for me which I haven't seen since childhood. Are these new cap powered models capable of longer powered flight than the best rubber planes?

[@joshuawfinn]

Capacitors generally don't give the same endurance as rubber, but they make for an extremely easy flying experience, and there's very little prep work and they charge fast, so it's a different experience. It's a ton of fun!

[@robertbrol]

What's the covering on it. Beautiful little airplane.

[@joshuawfinn]

0.6 mil doculam. I did a video on that a while back.

[@davidstambaugh569]

In England when you say gas power it really is either instead of alcohol.

[@joshuawfinn]

Correct, however for whatever reason the AMA and NFFS both refer to them as AMA Gas and Nostalgia Gas, respectively. SAM models typically actually are gas, running 2 stroke gasoline.

[@alfredobarrios4356]

Buenisimo josh. Este modelo es paresido a uno que costrui yamado cortazar

[@benrobertson7855]

Great stuff.be interested to compare the glide to the satellite. Regards.

[@joshuawfinn]

Yeah satellite will come later. No spoilers allowed on that story. 😉

[@themadscientest]

Makes me wish a model company that does scale kits would come out with a supercapacitor kit for a free flight cabin cruiser or biplane.

[@joshuawfinn]

For what it's worth, these 10F units work just fine in peanut scale models. 😀

[@themadscientest]

@@joshuawfinn I would just love to see a model company come out with a full kit for a stick and tissue model with complete power pack or even something like the Guillows Mini Models with a power pack. I had a foam Air Hogs supercapacitor plane as a kid and loved the simplicity, would have been nice if it was easily repairable.

[@jimbo2629]

There are plenty of Chinese foamy capacitor models that are cheap. They fly wonderfully if you give the wings dihedral. If you don’t they aren’t much good.

[@themadscientest]

@@jimbo2629 That's the problem, FOAM! I may just have to put my own power kit together for a project like that. Although right now I'm working on not flying models that use diesels!

[@gliderarts3573]

Just flew my 1st ever electric free flight today with timed Motor cut off....it was awesome..... I temporarily converted it to twin motor steering and it was so boring so I made it back into a free flight again I'll tell you motors on gliders boring...

[@joshuawfinn]

Glad you're enjoying it!

[@RichardTapp1]

Flying amongst the trees is so "unnatural" to me. I realise that is a contradiction. What could be more natural. But I have only flown free flight at fields with square miles of open land. So different. How did you get it out of the tree near the end of the video?

[@joshuawfinn]

We fly with what we've got. It's refreshing every time I go to big fields. None of our trees are particularly tall so a 20m carbon pole solves almost all retrieval issues.

[@MikeDavies621]

@@joshuawfinn So, where do you get the poles from, Joshua ? And what is their intended use ? Great vids you put out btw, I'm addicted :-)
