- nice version of 109. Review by johann
as others have said, it is important to keep the motor cool and some forward rake is a good idea to tame it's already demanding ground handling ( not really a big deal once you know what to expect) I just wish it was back in stock at the time of this review. Like my Dynam 262, I would like to get another from Grayson to have bone stock ( well, maybe just a new paint job) to have as an everyday, keep it in the car, flier. (Posted on 11/13/2015)

The paint detail and layout is very good.
Things I did that you should consider on your build.
#1 Rake the landing gear forward of the CG line.
#2 get rid of the factory ESC and replace with a 50 amp esc. though both Detrums have a stutter at below 10% throttle.
#3 glue or change the motor mount screws in place.
#4 cut a hole in the fuselage behind the cowling air scoop for ventilation
Go to the RCgroup web boards and read up on this plane. I haven't maidened mine yet, but will very soon
The cg came out right on the money with a 3000 MAH battery. if it's like the other Dynam models, I guess it will fly better with the CG forward of the recommended range. (Posted on 5/13/2014)

1. The fuselage packaging is poor and the top, front edge of the vertical stabilizer was dented in. Went to Home Depot and matched the paint colors from the horizontal stabilizer before I attached it to the fuselage. After some micro balloons, epoxy and paint, you can't event see the damage.
2. The retracts are weak and easily bend, even on gentle landings. I solved this by purchasing the 4mm x 75 degree Dynam retracts and changing the metal gear to 5/32" music wire. Then I put on Dubro 2 - 3/4" wheels and just left the gear doors off. Landings in grass were still impossible without nose over, so I added a 1/4" aluminum spacers to both the aft bolt downs for the retracts, and this put the wheels well ahead of the CG to help with roll overs. The 4mm x 75 degree Dynam retracts fit perfectly and are much better than the stock 3.6mm x 75 deg ones, because the metal gear attachment block is made out of aluminum instead of plastic. I have since had rough landings with no retract damage.
3. On all my planes I always change the elevator servo to metal gear, since this is about the highest loaded servo and susceptible to striping the plastic gears.
4. I added stronger magnets to hold down the canopy, after it flew off during one of my first flights.
5. Beware that the motor gets hot and can melt the motor mount. I read other reviews, where some have added cooling holes to help cool the motor. I intend to do this soon, as it is not starting to get hot in Atlanta.
I also added flaps and they work great to slow down the plane, and to make nice scale landings. I used one of the retracts that I removed to make a bomb drop and can't wait to try it. (Posted on 4/19/2013)
