| Jim , OTH | How is excessive free play in the nose wheel tracking best rectified? 07/17/2016 @ 18:08 [ref: 69720] |
| Ken Pickering Winnipeg, MB | Just picked up a CH300 partially completed. It seems that almost all the airframe compnents have been purchased (atleast the "special" ones like cowl, canopy, etc).
Plan to start on completing it in the fall of 09. Cheers! 01/30/2009 @ 09:37 [ref: 23583] |

| Phil Gower toowoomba, OTH | Hi I have an unfinished Ch300 project which is taking a long time to even get started on. Good to hear positive reviews, It may be for me a retirement project!!!
Need some + ve feedback to get on track with it. have all the parts, need to start. 04/22/2005 @ 05:32 [ref: 10008] |
| Tim the Builder , AB | Does Chris Heinz still have CH300 plans available or is it a classic shell game puzzle? 12/25/2004 @ 05:24 [ref: 8960] |
| Chris Horsten Brampton, ON | This Zenair CH-300 was bought with only 277 hours on it. After almost 20 years, the canopy is in excellent shape and the airframe also. A hard landing cracked and bent the vertical upright angles in the centre of the firewall, but this was easy to fix using the old metal fitting and new angles. Despite being stored or flown, birds nests were found under the belly pan. Panel is currently being refitted with all electonics and one electric Turn & Bank. This is a nice aircraft with plenty of room and a great useful load. Now if only I can get it to match some of those performance numbers you guys are getting!

| Bob Russell Winnipeg, MB | I am in the process of finishing off a CH300 that I bought partialy done . Currently am waiting for a canopy and and engine for it . I have had the pleasure of a flight in a CH200 and was impressed by the stability of it. I was lucky enought to get to fly it for a bit. I am anxious to have mine done but am taking my time with it .It is great to see pictures of finished airplanes and hear the good reports of performance and reliability.

| John Bagshaw Blind Bay, BC | I fly a CH 250 tail dragger/150 Hp Lyc. from a grass strip, El. 1555'. It has the CH 300 canopy, and cruises about 160 mph. It is a bit smaller/lighter version of the CH 300, so there are likely some differences.
My ASI does not indicates until 40mph, so I have no real idea of stall speed, flaps up or down. In both cases: a. Stall speed is somehwere below 40 mph; b. This airframe gives a definate warning judder and "oil can pop" just prior to the stall; c. Wingdrop is easily controlled by rudder even when the aircraft is held in a fully developed stall; and, d. Recovery is virtually instant with release of back pressure. I turn final with full flap, minimum 80 mph, decreasing to min 60 mph when wings level until over the threshhold. That seems to work well for this airframe, even when close to max landing weight. I'll add 10 kts to both in significantly gusty conditions. I normally take off clean, but will use 1/3 flap on a hot day when close to gross weight. The aircraft is not as pretty as an RV-4 or 6, but seems to perform about as well. And it is affordable for the average mortal. Great bang for the buck, and a joy to fly. 03/01/2004 @ 21:31 [ref: 6885] |

| Rob Treleaven Burlington, ON | Just bought a Tri-Zenith CH300 with 160h.p.Lycoming.
No P.O.H. - any comments/guidance re operations from owners would be appreciated. Great machine from what little flying I have done in it to date. Seems to want about 80-85 mph finals, 90 climbout, and roars along at 140 mph at 2400 rpm. Very stable. Requires little rudder, and power right to the runway on landing. Comments about flaps settings (seems like much more flaps available than needed - any elevator stall issues at full flaps??) /soft field/ etc. appreciated. My A/C is C-GHVL 11/01/2002 @ 18:17 [ref: 6005] |
