+1 Great Articles. With your permissions, I would like to do the same and distribute copies of these articles to our local clubs. Our local Hemet Model Masters field is now turbine friendly during the non-fire season. We have seen a significant growth in daily jet activities at our local field, so we are putting together some jet training lessons for the new jet pilots. These are great articles and will surely help us promote jet flyings in a safe and enjoyable surrounding.

Jeremy& Tiger,
EXCELLENT articles for anyone considering getting into R/C jets. Jeremy's update was right on the mark and Tiger's Checklist was superb. I printed copies for distribution at various events including a Model Forum in Syracuse, NY later this month. Credit will be given to both.
I'm also mentoring a couple of jet guys in my local club who are currently in the ICDF and EDF stages and I'll host a jet rally later this season. Currently, my local club has a ban on turbines and I hope to have this lifted. Your articles will also help with this action. Many thanks again for contributing these posts.

Gents, please feel free to use the information in my post, as long as it is for education and not for profit...and please re-download the checklist in the post above...it is also attached to this post...I uploaded the final version.

Also, consider the following jet turbine training syllabus - I'm interested in see yours if you have one:

Draft RC Turbine Aircraft Flight Training Syllabus

Assumptions:

A. The student is willing to learn and can set his/her pride to the side during training in the name of meeting several criteria before moving to the next step in training.
B. The student has flown a minimum of 50 flights on high performance aircraft capable of over 100 miles per hour.
C. The student is able to fly non-high performance aircraft confidently and with wind.

1. My turbine training plan starts with a Conventional Prop Trainer aircraft like an Arrow, Ugly Stick or Avistar for step by step training on basic maneuvers to confirm (or establish) a skill base. The basics must be solidified before moving forward. If maneuvers are demonstrated correctly, then I'll move right along to the next step. Solid habit patterns with the most basic aircraft are a required foundation for success flying any complex aircraft.
1a. Landing patterns, both directions. Constant rate of decent approaches with few, calculated throttle corrections. Square patterns and constant radius patterns should be observed.
1b. Go-arounds using "correct procedure" - throttle, level, gain speed, smooth pull up to 10 degree climb out straight down the runway, turn crosswind when past the end of the designated runway.
1c. Level figure eights and simple aerobatics WITH throttle control. Example: Loop starting with level flight at half throttle, then full throttle on the way up with half throttle when level inverted and idle when pointing straight down, then smoothly back to half throttle while reaching level flight.
1d. Takeoffs and landings WITH rudder control to maintain centerline!
1e. Mains only touch and goes probably should be a goal for aspiring turbine pilots, but not absolutely necessary.

2. Next is the simulator using a turbine with flaps and retracts.
2a. Learn switch positions and basic turbine flight characteristics with actual transmitter the turbine student will use for flight if possible.
2b. Learn how to use drag to manage speed and carry power through the final turn to land so spool up time is not a factor in a go-around situation.
2c. Learn how to apply brakes and simultaneously maintain directional control on centerline for landing.

3. Third is the new foam Habu with flaps and retracts. Do the flights practiced on the simulator in real life. Good foundational training will be solidified with application at the field with wind, sun and natural distractions.
3a. Transmitter switch locations should already be familiar. Practice take-off, gear up ASAP, straight and level climb out, flaps up before reaching full speed.
3b. Small flap deflections will give enough drag (10 degrees for take-off and approach flaps, 30 degrees for full landing flaps).
3c. Power on final approach with full landing flaps is an essential part of the learning curve.
3d. Aiming for specific touch-down locations is required before moving on to the next stage. An aspiring RC turbine pilot needs to be able to land "in the zone" on the runway. Each runway will require a different level of proficiency, but being able to hit a 20 foot long section every time with the Habu will build good habits. The aircraft should touch down before reaching the second 1/3 of the runway.

4. Next use the foam complex Habu with spool up lag programmed into the transmitter (3 seconds) to fly the full turbine waiver check profile. This is a confidence building phase. The goal is to make a waiver check preflight brief and maneuvers familiar so there are few surprises during the real thing.
4a. Habit patterns are further reinforced with the turbine lag training. Takeoff, figure eight, two aerobatic maneuvers with looping/rolling elements, high speed circuit, go-around, landing within 6 min.
4b. Before connecting the battery and taxiing out, have the student brief the required items for the waiver check (start/shutdown procedures and emergency considerations, fire-fighting equipment/ phone number, and turbine lag management).
4c. Go-arounds while managing simulated spool up lag (by transmitter programmed 3 second power ramp) with solid procedures: make the decision to go around, smooth full power input, flaps to approach setting, arrest descent, gear up, accelerate, flaps up all while maintaining runway heading, then turn crosswind when at least beyond the designated end of the runway. This procedure should be methodical and smooth.

5. Last is to ask them if they mind a visual check over their new (or used) turbine aircraft to make sure it is ready for start-up. Ask them to correct anything not in order before starting, make a recommendation on how to adjust or fix the item…resist the urge to do it for them!
5a. A new turbine will have to be properly primed to avoid a hot start or fire, ECU programmed for TX and fail safe set up to shut down if signal lost.
5b. The AMA recommends a person be on a buddy box for up to five flights on a turbine jet before a turbine waiver check. It is best if the student used their turbine aircraft, radio and similar buddy box. Any small issues that the student’s aircraft has should be able to be worked out within the five flights. Recommend flap deflection adjustments or rate adjustments if required. Allow the aircraft owner to make these changes and only assist, let them make the changes.
5c. A person might be confident and ready for turbine waiver check flight after five flights on a buddy box (or with experienced spotter if buddy box is not available). Practice all correct procedures so they become habit. Increase the number of flights if the person needs more practice to be comfortable and SAFE.

6. One option is for an experienced spotter to hold the fire extinguisher during preflight and turbine starts. Read off checklist items out loud as the new person completes each item to make sure a good solid foundation is developed. The person can elect not to use the checklist when they are on their own after the waiver check.

7. Recommend the aspiring RC turbine pilot for turbine waiver check when they are ready and provide names of turbine check CD and waiver check pilot to call for an appointment in the local area or a short drive away. Might be worth providing a simple certificate to the trainee that shows the competencies they've accomplished and that they are recommended for the turbine waiver check flight.

8. Give them a laminated, spiral bound copy of a checklist so they can review at a later date, or at minimum, for proficiency at the beginning of a new season.
