Status: offline 		Any one made any more progress with there Falcon yet? I have the new nose gear mounts done and cut the covering off the bottom of the wing to change out the gear mounts for the bigger Robart gear. By the way can I change my 85 degree to 90 for the mains that I was putting in till I found that yesterday? Todd

Status: offline 		Yes I had three flights on sunday. on the ali. a little trim , on the elevator, little trim up.
On the ele. make sure that the top of the stab is even with the ele. NOT THE BOTTOM.
The C/G is perfect at 13 inches. I even had one deadstick. and it like to glide. I did not use flaps. The Byron fan system works great at 4-1/4 outlet. I will try 4 inch outlet next , after that some props. I use spring/air Robarts.

Status: offline 		I just got my Falcon 120. I'd like to know what size motor to put in this jet? I'm thinking about a GMS120 or an OS140.

Have any of you out there tried these combinations? Thanks.......

For a jet I'd use a turbine. For a pusher prop job go with the OS140. Can't ever have too much power.

To start with I had a GMS 120 that I put in, but the next engine will be an OS 160. The retrcts are ROBART 520 series with a fork type strut I made. I spoke to robart and ordered parts to install a 656 ROBO STRUT in nose gear. The wings come off easy with a wing nut ( did not use 6mm plastic bolt supplied) and I plan to leave the booms on (THEY ARE A PAIN).



This from earlier in the thread.

Status: offline 		The Falcon pictured in Randy M. post is mine. It is packing
a Ram 750 air start. Fuel is 90 + ozs in a bottom 50 oz, 32
oz sitting on top of the 50 and the tank that comes with the
plane. The dry weight is 16.5 lbs and ballanced forward of the
13 in. for the test flight (nose heavy is much better than
tail heavy on first flight). The plane has not flown yet because
of other problems unrelated to flying, but hopefully by this
week end. Results will be posted, good or bad, using the new
XPS 10 channel reciever in a JR 10S.

ORIGINAL: JIMZACH

Hi guys, First flight was UGLY. GMS 120 with the 14x7 three blade is not enough, needs more blade to start with. RPM'S in the air were verry high but no push. Take off took for ever and then shot straight up , landing after cutting power went straight down. I found out on second flight both problems were better wih at least half flaps. For you guy's with JR radios down load BVM data safe program for BOB CAT it will give you basic set up and crow. Next step will be to replace GMS 120 with OS 160, Already ordered pusher pipe from WESTON UK.

Hello Jim, do you need that special pusher pipe that you mentioned or can you just run it with the conventional silencer, I'm not looking to set any speed records or anything like that... Another Question Bud, when you order that OS 160 do they have a different model for the rotation or do you just flip the prop???
Thank You Jim,
Mojo
