Default Duraplane conversion

I was just wondering if it's possible to convert a duraplane 20 http://www2.towerhobbies.com/cgi-bin...&I=LXE585&P=ML to electric, without spending too much money? I posted this is the beginners forum, but then I saw this... sorry about that

What is the budget? What kind of performance are you looking for?

My budget is anywhere up to 300 dollars total, and I'm not looking for performance, just a slow, stable, easy to handle trainer.

Hmmm...
Brushless suggestion:
AXI 2820/10 $115.00
3S2P Thunderpower 4200 mah $160.00
Castlecreations phenoix-45 $120.00
11X7 APC E prop- $3.00
= $398.00


Brushed Suggestion
Endoplasma $25.00 - http://www2.towerhobbies.com/cgi-bin...&I=LXW933&P=ML
GD-600 GB- $13.00 - http://www2.towerhobbies.com/cgi-bin...&I=LXSL79&P=ML
12T pinion (3.8:1) - $4.00 - http://www2.towerhobbies.com/cgi-bin...?&I=LXTG41&P=M
Castlecreation Griffon 40a $64.95 - http://www.castlecreations.com/produ...riffin-40.html
11X7 APC E prop- $3.00
10 cell GP 3300's $60.00 or 3S2P TP 4200 @ $160.00

= $169.95 with Nimh's or $269.00 with Lithiums.

The Brushed setup will be about 37 amps and 59 oz of thrust.

Woah. $90 for a 10-cell pack of GP3300s? I think cell cost is around $6.25 each for those where I shop. You could get two CP2400 NiCd packs for the same money, about $90.

Great Planes C50 ESC is only about $50, IIRC.

...and Tower's out of Endoplasmas as of this morning. If Tower's out, everyone's out, so don't bother asking where else you can get one

The Duraplane 20's wing loading will be awfully high. If you want slow, stable, and easy-handling, get a Tower Trainer 40 ARF instead. With the same power system, it comes out lighter than glow. By no means is it a stump-puller, but it does okay for itself.

Oops. Meant to type $60.00 not $90. Number and math corrected above.

I much prefer the programmable CC controller over the GP C50. The features are worth the extra $15.00

You can save a fortune by buying second hand equipment in the forums. You can feasibly cut those numbers by 40%, by just posting a Want to Buy (WTB)
The weight will probably be about 1/2 to 3/4 higher than the IC weight with NIMH's. However with Lithiums, that wont be the case.

Don't you guys think that the Duraplane is an unusual electric conversion. A foamie could be used and not require as much battery and motor. Check out the 3D Blade from Nesail.com for $39 .

With the size of this plane an its purpose, there arent many foamies out there that can fill the roll he is looking for. He may already own the plane and some people prefer balsa over foam. The blade is a very good plane, but on the other side of the spectrum for what he is looking for.

The Duraplane certainly IS an unusual electric conversion, which is precisely why it should be done!

I just suggested that perhaps a lighter balsa trainer might be more suitable for learning.

Thanks for all the help.

Do you think there is any possible way to run on 8 cells? I have a super brain 969 charger at home, and it only goes up to 8 cells max.

Is ther any time of electric plane that can really take a beating? If a foamie can handle ALOT of crashes then I'll deifinitely go for it. I just want a basher until I refine my flying skills.

You can swing a bit larger prop and run it on 8 cells. If you are looking for something that can handle crashes well..then look at foam airplanes and steer away from balsa for the time being. Planes made from EPP are very forgiving. Of course you could convert a coroplast plane as well since they are nearly indestructable.

This may not interest you but I have a suggestion for a plane that is easy to build, very strong, low cost and great to learn on...

JK Aerotech Big-T...72" span, all foam construction $100.00
Kyosho Magnetic Mayhem Reverse motor $20.00
Master Airscrew 3.5 to 1 gear box $22.00
Astro Flight 215D ESC $40.00
10 cell GP3300 battery packs $60.00 ea. (need 2)

As I said, just food for thought...

Bill
