I'm looking into buying the KatanaP 46" kit soon and I'm wondering about which engine to buy for that plane. It will be used for 3D, and I'm wondering if a OS .46AX engine will be enough to do all the 3d acrobatics like hovering and so on...

I know I could use a 4 stroke engine with a big prop and not worry about torque, but I'm pretty new to this hobby and I rather stick with 2 stroke engines for now.


Thanks!

If you keep the AUW down under 4 1/2 pounds, a 46 AX will hover it at around 1/2 throttle and power it well for just about all 3d moves. I run a 46 AX on my OMP Edge and it has plenty of juice to pull vertical from a hover (and it's at about 4# 10oz after repairs). A Macs muffler of mousse can pipe will add even more punch to the AX.

If you're new to the hobby (as you said) and are just getting into 3D flying, may I make a suggestion? Try the OMP Edge. The ARFs are sold out but the kits are available. It's a much better intro plane for 3D than the Kat P, IMHO. The Kat P is a very capable plane but requires a bit more skill on the sticks, especially down low. Edge is very capable also but it's wing shape makes it very stable in hovers and lets it slow to a crawl. Just my $.02. They're both great planes but I think the Edge would allow you to learn more 3D at a better pace and comfort level.

Hey Berwyn Bill,

Thanks for replying!

John from OMP recommended the same thing you said. Basically in order of difficulty, or learning order I should go with the Edge, Yak and then finally Katana.

I really want a kit tho, and the Yak 57" is the only one left in stock... Apparently it's a decent plane to learn with. I have never hovered or done any 3d stuff but I have practiced on a lot of G2, even tho in real life it is really different according to most people.

I will wait 1 month, see if they restock, if they don't I'll go with the Yak 57" profile kit.

Cheers everyone!

When you say the 57" Yak, do you really mean the 47"? I hadn't seen a 57" version.

On the OMP website, they show the 47" Edge Kit as being in stock, but John may have given you a better inventory check. The Edge and Yak were designed by Mike Pilkenton, he's online here as Salmon . They are very good designs. I don't think you would ever be disappointed in the Edge or the Yak. Check with John or Dion about the 47" Edge Kits stock status. If you can only get a 47" Yak kit, that's still a great plane, just get used to it slowly and it will become your evil minion!!![sm=biggrin.gif]

Yes, the 47" Yak and the 47" edge are very very simlar and both could be used as very good 3d trainers. The Edge is the king of 3d trainers but the Yak is a very close second. the Yak was designed to have a little more yaw authority or agility. Some stability is given up for this but still a very stable plane for learning. The Katanas are a step up from them.
