The International Cessna 170 Association

Hi All Can anyone advise what the sticker on an original set of Winter cowl baffles said for removal temperature? I’ve made myself a set but don’t have a clue what Cessna recommended as to the max temp they should’ve used under? I’m heading North to our remote came on wheel skis, I’ll be taking off ...

Bruce, have you managed to find a set of winter plates for the later model C170B's to copy?

I'm looking for a set and would happily pay someone for a original or fabricated set expecially for the upper cowl.

She's pretty cold up in Northern Canada and the old girl is freezing.....

Thank you all for the great feed back. We are certainly baffled by this change in trim characteristics since removal of the tail. Being there is no horizontal stab adjustments and that it went on exactly like it came off we are stumped by the shortage of forward(up trim tab) adjustment, even though ...

With elevator faired my measurement following the settings listed in the operators manual was set up at 13 degrees. Unfortunately we did not measure the up trim before we disassembled the tail. Now clearly I'm finding for wheel landings this 13 degrees is not enough, expecially the more flap you add...

So are you saying you should measure the max trim tab deflections(up and down) with the elevator full up on the stop and full down on the stop? So which way do you place the elevator to measure the up deflection of the trim tab(up or down)? I had a Freind check his C170B to see how many turns his tr...

Yes your experience is matching mine, but even with twenty degrees of flap with C of G between middle and absolute aft(half way between the two) at or near gross weight I lack the forward trim I would like for a tail up wheel landing with it set at 13 degrees. I'm wondering if other members were to ...

Thanks for all the comments, being there is no adjustment on the horizontal stab and it was placed back on as it was removed, I can only assume the original trim up setting was beyond 13 degrees. The issue then is, since when do C170B's run out of forward trim for wheel landings loaded slightly aft ...

Looking for some advice on elevator trim adjustment. First some back ground info; I've always wheel landed my 1954 C170B without ever running out of forward trim. In summery, as I approached the threshold and rolled in forward trim to give me slight nose heavy control feeling so that I could just re...

Your results are interesting as they have mimicked my last flight test yesterday. This baffled me as my radical right wing drop experienced before was now only subtley noticable as I added flap being more pronounced the more I added but nothing in comparison to what it was doing before(now totally m...

Any luck testing out how your plane stalls skis on and off?

Any notible right wing drop with ski's on that isn't there skis off?

That's great, appreciate it. Please try the stall power off no flaps up to 20 degrees and power on the same.

Did you say you had the larger Sea Plane prop?

Stogie Do you have the larger Sea Plane prop? Would it be possible to have you conduct a few stall tests before you put your ski's on, then again with the skis mounted just to cross check the differences skis on versus off? Today I removed my ski's and reconfirmed the aircrafts rigging is dead on, t...

That explanation makes sense but opposite to what we had guessed! We were thinking perhaps the down wash of the airflow coming off the descending prop blade was hitting the top of the right ski pushing down on it, your explanation makes more sense(or maybe a combination of both?). Its interesting bu...

Sorry, poor terminology, its when the aircraft stalls it drops a right wing with skis on versus straight and level with ski's off.

Has anyone noticed a difference in aircraft trim/STOL with wheel ski's installed versus no ski's? Since I installed my Federal AWB2500 wheel ski's, in a Stol my 170B now drops a right wing. To be sure the aircraft rigging was still correct I removed the ski's and verified the aircraft flys straight ...
