RE: A plane for 4 geared speed 400's?

Whew - brave choice - that kit's a lot of work! I've seen quite a few threads on RCGroups on that one, and everyone seems to think it flies pretty well. Just hope you like building with sticks!

I'm about to start on a Short Solent for quad 400's:

RE: Suggestions for 60-90 sized kit...any nice-flying scale subject

Great suggestions guys, thanks - keep em' coming. The reason that I can't deal with nose gear is just that the field is too rough, and has the odd gear-eating badger hole that needs to be avoided....

Suggestions for 60-90 sized kit...any nice-flying scale subject

Hi folks,

A friend and I were looking for inspiration for winter projects for next season, and wanted to try something a bit more scale-ish than normal. We both have ample flying experience, so...

RE: Help ID'ing new toy

Yep, definitely a Gerasis DG-600, I had one for a few years. Bad news...I hated it. Brutal low speed handling, and very spotty quality control.

Do NOT get it too slow or it will spin, and it...

RE: Tow Plane Suggestions

Hey guys,

The Calgary group is lining up a Brison 2.4 powered UltraStick 120 (mine) and a ZDZ80 powered Bridi Big Bee for this season, both of which are proven towplanes.

Tip Plates

Hi all,

Are vertical wingtip plates legal in this class?

Thanks,

RE: pre guessing a wings weight?

Not really, I'm afraid. The only guideline would be that there's a bit of an exponential relationship between required structure and size.

It's always easiest to use similar kit/design weights,...

RE: Retracts for rough-field operation - 16 lb model

Okay, thanks, will do. I'd really like to keep the retracts if possible...a fixed gear version of a retract-equipped warbird is just wrong.

It would be my own design, since I don't know of any...

How would I go about estimating the effective washout that would
result from a transitional airfoil series? Programs like LiftRoll
don't account for this possibility.

RE: Senorita into a electric Tow plane

C40 as in Hacker C40? Not much beyond 2m. You need a B50 to start flying 0.60 size models, let alone towing anything. The big AXI would be a good choice (16-30 cell motor from Hobby Lobby), and not...

RE: Senorita into a electric Tow plane

A 0.40 would tow light 2m glider pretty well, but not much more than that. Figure something along the lines of a Zenoah G62 or Desert Aircraft DA50 for the 4m and up range (my next project, I hope).

RE: Senorita into a electric Tow plane

You can't use the high start hook to tow, because then sailplane will want to climb like it does on a high start launch. The release always goes in the nose (or the chin, worst case), and can be as...

RE: Senorita into a electric Tow plane

Not really a fair comparison, since the Actro is WAY more powerful than a .61FX.

I can do mine however (US$), about equiv to a Zenoah G38 @ 40A, or more at 50A like planned for next season:

RE: New to sailing, need advice

Proper hand launch gliders are usually 8-12 oz and reasonably fragile, is that really what you're looking for?



Technically - sink rate. Practically - nothing.

RE: Senorita into a electric Tow plane

RE: Senorita into a electric Tow plane

Sorry, that was wrong. It should have been 100W/lb for the combo (ie.)

13.5lb tug + 12 lb sailplane requires 1550W, give or take.

Towing it fun, but it's challenging (especially for the tug...

RE: Kadet Seniorita electric conversion

A Senorita would be too small to properly tow 4m sailplanes, but a Senior might be okay. They're both a little slow.

At any rate, check out my article on www.liftzone.com
