I just ordered the Katana V2 .46 yesterday. I plan on using a Satio 82. What's your opinion on this engine with this aircraft? What prop would you suggest? I plan on using the new Spektrum DX-7 radio for this bird. I'm already using it for other aircraft and love it! Question is, using the servos that come with the radio. Will they be strong enough for the job? They are the new DS821 sport digital servos. The specs are: Torque: 72 oz/in @ 4.8v, 88 oz/in @ 6.0v. Also, should I use a 6v battery vs a 4.8 battery? Which one would you recommend? And finally, do you guys recommend mixing flaps to elevator for tighter loops and stonger elevators?
Thanks in advance for your help!

I am flying this plane electric.

I do have an 82 on the Fusion. The saito 82 is a wonderfull motor for these 4.5 pound airplanes. I use the 14-6 APC. You could also use the 14-4 depending on your nitro content (be careful not to over rev with that prop).

I never used those servos, but 88 ounces at 6 volts sounds great for a plane this size. I use 6 volt batteries. If the servos can handle it and you aren't trying to save every last bit of weight, there is no reason not to use 6 volt batteries. The servos are stronger with them, why not, you know?

Fly the plane around and see how you like it's performance. once you are used to it, mix the flaps on a switch and try. I bet it would make it do violent waterfalls. I personally do not care to involve elevator to flap mixes to improve elevators.

Thanks for the reply! What brand and mHa 6v battery would you recommend?

I would go to http://radicalrc.secure-mall.com/sho...=1&cart=528003 and get one of the new 1400 Mah NiMh batteries. They are the cutting edge of NiMh development from what i hear. I have a 4 cell one on a gas ignition.

Radical RC has only done good things for me when i buy from them.

Go to "battery packs", then "receiver packs" and scroll down a few pages.

I used a 14x4W on my saito .82. I also agree that Radical RC is the place to go for batteries. I am using the 6volt 1400 Ma NIMH receiver packs in all of my profiles. They are lighter than most standard 4.8 volt packs that you get with the flight packs.

Thanks guys!
I ordered a 6v 1400 Mah NiMh battery pack from Radical RC yesterday. I also ordered an APC 14x4W prop.
My Katana V2 .46 arrived yesterday as well. I'll start on it tomorrow. The quality of the ARF is great isn't it?

Harry, you've got a great combination there for the Kat. Should be a high performance setup all around!

After flying U Can Do 46's and Hanger 9 Twists a few years, I just ordered a Katana too. Should be here this week sometime. I'll be keeping up with posts on this thread to see what the best package seems to be....

Harry let us know how that DX 7 works out. Im wondering how much room you have to set up the receiver and such.

Dennis,
It worked out GREAT!!! Plenty of room for everything. I used a Saito 82 with a Tru-turn 3-D spinner out front so I had a nose heavy aircraft. I placed the rx battery in the rear compartment of the left wing. I placed the rx and switch in the center compartment of the left wing. I still had to add lead to the tail to balance. I used the servos included with the DX-7 system with a six volt battery. The system works great! The performance of this aircraft with the Saito 82 and the DX-7 is really amazing!!! Unlimited vertical with the Saito 82, and outstanding control with the DX-7 system. I'll try to take a few pictures tonight and post them if you guys are interested.

Harry that sounds good....would like to see how you mounted the 2 receivers in the wing

What LG did you guys use? I have read a few places the the stock LG is very weak. I ordered the Tethierite gear from OMP and after getting them I got to thinking that CF may be the way to go. The Tethierite is well engineered and a great product, but I'm trying to save every Oz. I can.

BTW - OMP seems to be a great Co to deal with. I have talked to them on the phone to order stuff and the service is fantastic !!

Thanks!

As for CF gear don't bother. You won't save any appreciable weight and every CF gear that has been used on a profile will break with little abuse. CF is nice and light and certainly strong in most applications however landing gear is not one of them. There are a few applications where CF has been laminated with other composite materials creating a worthwhile structure but again, weight savings is minimal on this scale.
