How To Use This Mod Section

CLICK on Illustration notations and diagram above or Mod Description below for full mod descriptions and photos.

When determining what mods are applicable for which specific model or vintage Mooney, it is important for you to understand that our Mod Menu is presented in sort of a Building Block process. Older vintage Mooney owners should also see 201/MSE and M20K/Turbo etc. sections for many more mods which may be applicable to their model Mooneys as well.

Many of the mods listed here are only applicable for pre-201's, but many other mods listed on the M20J/201/MSE Section are also applicable for pre-201's as well as other model Mooneys. Therefore, older vintage owners should also refer to the M20J/MSE Section as both sections combined constitute the bulk of the mods available for Lycoming powered non-turbo Mooneys.

Besides contacting us directly and reading the other information available within this section, we also recommend you print the Mod Menu's 3 sections for future reference later.

Note: Most every mod listed also has a Model Applicability Note.

#100SMM: 201/212 Trophy Speed Kit Mod Installed: $4,995.00+/-

This kit is most effective of any speed mod we offer! Not to be confused with ony other gap and faring kit. It is the heart of any Pre-201 speed process. As installed at our facility is actually a complete assembly of most all of the OEM M20J/K style farings and seals commonly sold individually (by others), but in our installed kit, we include most together forming a very comprehensive and effective 211 Flight Speed Speed Kit Mod. For most pre-201's it usually contains some 36+/- components, and when done in it's entirety, is the single most effective speed mod we offer.

We consider it the Cornerstone Mod for all Pre-201 M20's and all owners say it is A MUST! (Applicable to: M20C, E, F, G)

Quality OEM Mods Aren't An Expense, They Are An Investment

#120MM: OEM MSE/Ovation Style Fiberglass Sculptured Wing Tips* Installed: $6,995.00*+/-

This mod involves duplicating the factory M20J and on installation by changing the outboard wing skins along with installing the newer internal outboard aileron rib/counterweight assy. Usually, new ailerons are also included, but you should check with us for your specific model M20. In short, this mod duplicates the stock factory Mooney OEM Original Equipment Mfg.) installation exactly, and is not to be confused with other less efficient and un-attractive (non-oem "bolt on" type) W/Tips which retain the original aileron counterweight etc. Options: Install Internal Hi-Efficiency VOR Blade antennas internally inside the Fiberglass Wing Tip Assy. (And remove the stock cats whisker VOR antennas commonly found on vert stab/tail), add: $1,995.00+/-Strobe lights or Forward Facing Recognition or the nifty additional Peripheral Quarts Landing Lights, add: $1,590.00+/-

*Important Note: This mod is not to be confused with the less expensive but esthetically pleasing Lasar style add on type tip. The Lasar style tips are available for approx. $2,995.00+/- installed, but DO NOT change the aileron counter weights or the end wing skin. (Applicable to all M20 Aircraft prior not yet having same installed)

#123MM: OEM Mooney MSE/252/Encore Overlapping (Full sealing) Nose Gear Doors Installed $1,495.00+/-

This mod not only increases cruise, but also assists in significantly lowering the exhaust din and thus making the cabin quieter. This simple mod is sooo effective, we strongly recommend this for all Mooneys and feel there is no excuse to by flying a M20 with out them!

(Applicable to all M20 Aircraft prior to '84 not yet having same installed).

Mod Notes: See separate price lists in other sections such as Interiors/Glass, Avionics/Autopilots for current prices, and applicability prior to ordering custom interiors, avionics, Bose Headsets, avionics or autopilot installs. All Mod prices herein listed are estimates as we reserve the right to change specifications, prices, and applicability without notice and upon examination of your individual specific Mooney. Damage History or previous Mods may make your aircraft non OEM and thus affect our ability to install certain mods etc. Any and all quotes therefore, are not binding until inspection is made of your aircraft and may be subject to change due to items out of our control such as hidden damage, mods, corrosion, etc.

Most all our Mooney Mods utilize the much preferred OEM (Original Equipment Mfg.) factory procedures, components, and parts unless otherwise noted. Painting (although offered) is never included in pricing except where specifically noted otherwise.
