200 flights of the Mini Max and counting..

201 actually at this point in time.

On my second motor, a Graupner speed 280.

Did a nice roll yesterday.. accidentally. If only I could remember how I did it.

Can I make it to 500? Or 1000? You can bet I'll be trying.

Kevin.

Mini Max lover.

I hope to be flying mine by next weekend.
It sounds as though the motors that come stock with the Mini Max are a little more durable than the GWS ones.
Best of luck! I hope you hit 1000.

Thanks Bryan.

I suppose I should include some pics of it's present self.

Note the full size 8x6 Tiapan prop. The original was damaged by cow. Note the new tail section. Original was chewed by cow. Made some mods instead of using the plastic wing joiner too.

Original motor died after 57 hours of flying. Maybe they don't like cow spit? I've noticed The Graupner speed 280 runs cooler than the stock mabuchi motor so I'm expecting even longer life from the Graupner.

Great VonBaron!

I got about half way through building a Mini Max for my father last night. This is our family TigerMoth squadron's first example of this more powerful airplane (although I'm "tricking out" my TM with a homemade twin motor and CF reinforcement -- so we'll see who wins Saturday weather permitting).

I've read through much of the information here on E-zone about the Mini. I'm happy to report I have one of the "newer" kits with an aluminum wing socket and fiberglass spars. That seemed to be the key to getting a great airplane.

I was planning on putting packing tape along the bottom of the wings as I do with the Tigermoths.

I'm soldering together 7 AAA NiMH cells for a pack.

Flybry, we really ought to put together a local E-Fly club and schedule events once a quarter or so. I guess MRS blew through their first 10 Mini Max's (the ones for $49 including ESC and Battery) in less than 48 hrs. They have 30 more on backorder.

I'll post pictures as I complete the plane and take the first flights.

Melfsmite, 7 AAA nimh cells sound just right for Max.

Let us know what you think of it.

Hi VonBaron,

Can you let me know a little about the difference in the stock Mabuchi and Speed 280?

Does the Speed 280 seem to have more power than the Mabuchi?

Does it have a longer life?

What kind of batteries do you use on each?

Holy Smoke!
I didn't realize that Electrics were picking up that fast here in Salt Lake.
As soon as the Olympics are over, I'll have a lot more time on my hands to start organizing something.
I definitely want to start a club that's for sure!

Tinsink, the differences are minor it seems. The shape is different (the speed 280 is round) but it isn't any heavier. Still fits the same gearbox. Power output seems the same for the same cells and prop. Endurance is the same also.

It's a good replacment but not a step up in power at all.

I haven't flown the Graupner speed 280 to destruction yet. I've only had 33 20 minute flights (11 hours) with the new motor so how it's longevity compares to the original yet I don't know. However the Graupner 280 does seem to run a little cooler so maybe it will last longer. Then again I'm spinning a full size prop now so the rev up load will be greater.

BTW the Graupner is still a Mabuchi motor relabled. Graupner pick the good ones so I tend to trust them more than others.

I finished my father's last night. I'll attach a couple of pics.

One thing... the firewall looks VERY weak to handle the stress of landings. Vonbaron, how did you strengthen yours to last? I added a little more epoxy around the bottom, but I'm thinking a piece of triangle stock glued into the bottom of the plane to the firewall would help immensely.

Any advise?

Oh, two more things. First, the "addendum" wing fix still includes bamboo struts. They have been lengthened. The joiner is aluminum and the taping has been widened to add strength. The new wing struts are not fiberglass but the wing seems very robust with the change.

Second, those wheels are freeking heavy. It'll be a nice change to have some durable ones after the TM "break a wheel a month" scheme -- but sheesh -- those things are bricks! Has anyone tried the hyperlite wheels on this plane?

Thanks!

Melfsmite, yes the firewall does come away on a good ding. I just epoxied mine back on and it took a cow to remove it again.

I love those Mini Max wheels! The Max has plenty of power and hauls them up no problem. I didn't think they were heavy. Of the hundreds of landings I've had I've only ever nosed over once with them in thick grass.

Nearly forgot. That tail skid will come off after a few landings. I put a foam skid on mine. Some people use a little tail wheel.

Running a dowel down the full length of the fuse helps prevent fuse crumple too.

Great!

Thanks for the advise Vonbaron.

It looks like tommorrow lunch for a flight test.

Hi there Gang

I'm looking for an r/c aircraft that's a little more capable with power and ability than my TM, but can still be used in the local park/soccer field. Would you recommend the Mini Max??

I'm getting frustrated at the choice of models available. I'm on a limited budget.....

Although the minimax does have a more powerful powerplant than the old DX-A on the Moth, I wouldn't say it is more "capable" than the Moth and it does take a little more room than the moth IMO. If you really just want a new plane then the Minimax is a sweet plane that will loop all day. If you just want more power then get an M100 for the Moth and you will definitely know what "capable" means.
