Status: offline 		Well I ended up going with OS .46's. They were on the shelf and I did not want to wait for the TT.

Just for everyones benefit. If you choose the newer OS .46 with the remote needle valve, you have to modify the engine mounts that come with the kit. You can not put the engine 11.2 cm from the firewall if you use the OS. Since the mounts that come with the kit are quite beefy I modified the mount by taking half the surface off the part of the engine mount where the needle valve hits the mount, with a band saw. You can also relocate the needle valve or use differant engine mounts, I figured it was easier to modify the mount. I did not have a camera charged so I do not have any pictures of the mount yet.

Status: offline 		The big problem with this plane is that when you set it up with standard .46's and do everything by the manual the plane is REALLY tail heavy. My solution was to build a battery tray for the nose of the plane. I just could not bring myself to rely on the 4 nose cone mounting blocks that got CA'ed in place to carry 20 ounces of lead. Yes you read correctly 20 ounces of lead. So what I will be doing is placing a larger 3300 maH Ni-MH battery in the tray and any additional weight that my be required. I am certin that I can get the required weight down to 6-8 ounces. I will post more when I know for sure.

Status: offline 		Has anyone else had a problem getting this plane to balance?

I am not to that point yet. I have not had a chance to work on the plane since I bought the engines and I want to bench the engines really well before they go onto the plane. I suppose I am half way completed and have not had any real problems with the kit except the engine mounts and the pictures in the manual need a little description at times. I am going to put three blade props on the plane for the look. I figure it will have more than enough power. Stinks that I can not use the supplied spinners but I think it will look better with the 3-blades on it. Will probably order some polished spinners when I get a chance.

Du-Bro has some excellent plastic spinners for three bladed props. Tru-Turns run about $30 each for 3b spinners. Spin-Right and Dave Brown also will supply 3b spinners, but check the balance. I've seen them 'way off.

Status: offline 		Well I built my battery tray and put 2-1650 maH Ni-MH AA packs running in parallel thru sperate switches, I still had to add 9 3/4 ounces of weight to balance it at 85 mm back from the leading edge at the cabin, mid point in the range. But I am happy, I was able to cut the weight by more than half of what it was going to require if I left everything in the position the manual calls for. It is not the 6-8 oz. I was shooting for but if I decide to move back to the 90 mm location I will be at 7 oz. So I can live with that.

EXACTLY!!!! The correct CG is 95 mm!! But you may still need to add a little weight to balance.

Status: offline 		You're going to move the servos in front of the spar.... not a bad idea at all. I was really suprised to see that it required any nose weight at all, I was guessing it would come in rather nose heavy as far fwd. as the engines are.
