Nitroplanes,

I have sent three emails asking for information on the Cessna SkyMaster 337 Twin 25, the first was March 6, the last was last night.

I have received no response. If you cannot help me that's fine, but at least have the courtesy to respond to a potential customer.

The subject line is Cessna SkyMaster 337 Twin 25.

thanks in advance

ok can you ask me here and I'll help you.

Thanks

Ok, I am interested in the cessna 337, but would be converting it to electric using outrunners as suggested.

I would like to see how involved/difficult it would be to do the conversion, can you send me a copy of the instruction manual or at least the pages that show the front/rear under the cowls.

thanks

IMHO I find the most difficult thing with conversions is the battery access for quick changes at the field.

Keep this in mind when you look at potentially converting the plane.

Thanks opjose, yes you are right that is always a big concern. I am hoping to get the entire manual. Just wanted to start with the motors.

thanks for the feedback.

I'm in the process of getting this manual for you in electronic copy. Thanks will email you when I have it.

Thanks

John,

Thank you so much for taking the trouble to help me. If I had known about the forum I would have started here.

Again thanks for the quick response.

I have recently purchased the edge 540 25-45" ARF from nitroplane and I'm interested in what types & sizes of motors that I could use to get it running well...thanks

Largely this is up to you. You should try to work things out yourself if possible.

However here is a hint.... and pretty much outlines what I would be doing ( or just might go ahead and do ) with this plane.

The specs call for a 500watt motor which sounds about right for very good performance.

I put a BP Hobbies 2915 5D, motor in my similiarly sized and weighted Super Sportster EP, with a Tower Pro 60A ESC ( from NP ) and two 2200 mAh LiPo batteries ( also from NP ) in a 3S2P configuration to produce 4400mAh.

I have been EXTREMELY happy with the performance of this .30 equivalent. The plane is a rocket and will fly for just shy of 30 minutes ( !!!! ) on a charge.

BTW: I purchased 4 more battery packs ( again from Nitroplanes) so that I can fly it for a solid hour and a half without recharging, with battery changeouts every 30 minutes.

In NP's stable [link=http://www.nitroplanes.com/c3exoubrmo11.html]THIS MOTOR ( CLICK ME! )[/link] would be about the same.


You would either have to wire up your own deans connector cable to produce the 3S2P configuration or you could purchase one already made from other vendors.

For maximum longevity and good speed I used a 9x6E prop, but for slightly shorter run times but far more vertical/hovering power I use an 11x7E prop.

Remember with electrics, the PROP determines how much power your electronics draw.

If you over prop, you run the risk of damaging the electronics, as the prop will demand more energy than the electronics can handle.

Underpropping results in longer flight times.

Thanks for the reply...the model has arrived and now all I need are some CLEAR instructions...[img][/img][img][/img] does anyone have any suggestions on some GOOD how to build books??[img][/img] I have built models before, but this is my first RC Airplane, so I'm pretty much in the dark...thanks for your time and effort...Tim

Just download the manuals for other similiar planes, ( Hint: Tower, Horizon ) and study those.

Your should really not start with a Nitroplanes ARF as your first one.

There will be a few things you will encounter that you will not know how to deal with.

If you've put together other ARF's before these will be trivial points, but for a novice it will be a big deal.

Find someone with experience building ARFs ( preferably with 2-5 under their belt ) and ask them to guide you through the build.
