RE: TBM Shock Jet
mine shows a weight of 1lb 8 oz's without the wing, and it does fly slightly nose heavy, I will move both flight batteries back a little more. but I think the plane is very tolerant of cg range.

RE: TBM Shock Jet
I weighed mine last night. Without the wing I'm showing 2.3 lbs on the front wheel with the UAT empty. I checked the gear last night. The axle holes are offset .5" from the center of the 4 bolt mounting hole pattern. The way I have the gear mounted, the wheels are offset towards the rear of the plane. If I turn the gear around, it will move the mains 1" forward. That should reduce the amount of weight on the front wheel. I haven't checked the CG yet but I have 2 heavy battery packs in the nose that can be moved if needed. It shouldn't be a problem to get this set.

RE: TBM Shock Jet
Kevin, That is a good weight. My plane with out the wing was in the same area. When you put the wing on the weight comes off the nose wheel. Check yours with the wing on and you will be very close I think.

RE: TBM Shock Jet
Meesh, I have two five cell packs, one is in the nose and the other is on top of the fuel tank. I think I will move the other back some more to suit my flying style.

RE: TBM Shock Jet
Kevin,
I rotated the main gear last night so that the straight edge of the aluminum is facing the nose of the plane. Measured without the wing installed, the weight on the nose wheel went from 2 lbs 3oz to 1 lb 12 oz. A 7 oz change! That should hlep rotation on take off. BTW, I'm showing nose heavy with my two batteries up front. I'll try moving the Rx battery rearward. thanks Bob |

RE: TBM Shock Jet
Ok I put 3 perfect flights on the plane today.
As for landing, you guys should not be having issues. Near the end of your downwind pattern, be full flaps and idle power. Make your turn for final wide and use it to lose altitude. When you come out of that turn, you should be adding about 4 clicks of power to drive the plane to the runway at a level attitude. At about 30 yards from the threshold of the runway, chop it to idle and hold the nose level. You will have a perfect sink and a slow landing and it will even ride a wheelie for you down the runway. |
RE: TBM Shock Jet
Still can't get mine to flare (or hold the nose up during short final) unless I keep power at about 1/4 right up to touch down. If I go to idle before touching down, the nose drops and the nose wheel touches first causing it to bounce back into the air. I have learned how to prevent this by keeping the power up, but I would really like to be able to flare and then hold the nose wheel off until it slows down a bit. It measures 1.4 pounds on the nose wheel. The only thing I can think of that might be contributing to this that I have to mix quite a bid of down elevator to keep the nose down with full flaps. I guess my next thing to try is to change receivers so I can use crow. As has been suggested, this should allow me to reduce the amount of flaps needed for landing and thus use less down mix.

RE: TBM Shock Jet
Hey Guys,
Finished mine last night. Total weight is 15 lbs. 3 Oz. with the UAT full. PST J600R with the ECU battery mounted in the nose, Rx battery mounted above the fuel tank just behind the bulkhead. Question about the CG. As configured, without the wing, it balances 2 5/8" in front of the main gear, 3/8" back from the recommended 3". How sensitive is this plane to CG changes? Should I add some nose weight to move it up to the 3" mark? Thanks Bob |
RE: TBM Shock Jet
That's just about where mine is and it's fine. I started with mine exactly at the 3"CG and felt it was extremely nose heavy (still flew well ..just not where I like it). This plane is very tolerant of CG range. Best of luck!

RE: TBM Shock Jet
Thanks Cagmo. That's what I needed.
If the weather co-operates I will maiden it this Saturday. Bob |
RE: TBM Shock Jet
mine was right on the 3 inch mark as well for maiden and subsequent flights that weekend. flies fine but is nose heavy and required a bunch of down while inverted. I will be moving it back before I fly it again, probably at least 1/2 to 3/4 of an inch. years of flying giant scales three inches behind the aft cg has made me used to tail heavy flying.

RE: TBM Shock Jet
The airplane holds a good attitude all the way down final. I found that you can be at idle all the way in, assuming its not gusty. The plane floats for days, if your too fast you will not have much of a flare. The CG on mine is per the directions. You can see the attitude at landing in the pics above and the plane is less than 15 MPH.

RE: TBM Shock Jet
made three flights Saturday and six flights today, overcast weather but finally got some rain so I made my first flights in months here at home. full flaps on landing require a good amount of power to keep it airborne, lots of drag. smoke system was about useless today with the gray skies. replaced the 1250 nicad ecu pack with a 4400 li-po, made all six flights today on a single charge and just finished charging, 966MA back in to peak.
Off to Woodland next weekend. Kevin |
RE: TBM Shock Jet
Bob,
The vent has to reach the highest part of the tank or you'll never get it full. Bob |

Thanks for the clarification!
I looked in the Fridge after I saw your picture and found what I needed. Thanks! |
RE: TBM Shock Jet
Guys,
I maidened mine on Saturday. It was quite windy,15mph, but it was going right down the runway. It took off by itself in about 100' off of grass and climbed out nicely. It flew very weel even at 1/3rd throttle but I noticed that it wanted to climb at high throttle settings. Anything half throttle and less was fine. CG is about 3/8" to 1/ behind the rcommended 3" without the wing. It stuck nicely on landing. Any suggestions?? Bob |
RE: TBM Shock Jet
mine climbs at full throttle as well, but i only use it for verticals and it is not really that much of a bother so I just fly it.
Kevin |
RE: TBM Shock Jet
Same here with full throttle, like Kevin said, just fly it.:D Here's some pics in the air with smoke.

RE: TBM Shock Jet
If that's normal then that's OK. I just never heard anyone mention it.
Thanks Bob |
